Plasma technology, which can instantaneously transform air molecules into reactive species stimulating plants, potentially contributes to developing a sustainable agricultural system with high productivity and low environmental impact. In fact, plant immunity activation by exposure to a reactive gas mainly consisting of dinitrogen pentoxide (N₂O₅) was recently discovered, while physiological responses to N₂O₅ are rarely known. Here, we demonstrate early (within 10 min) physiological responses to N₂O₅ gas in Arabidopsis. Exposure to N₂O₅ gas induced an increase in cytosolic Ca²⁺ concentration within seconds in directly exposed leaves, followed by systemic long-distance Ca²⁺-based signaling within tens of seconds. In addition, jasmonic acid (JA)-related gene expression was induced within 10 minutes, and a significant upregulation of the defense-related gene PDF1.2 was observed after 1 day of exposure to N₂O₅ gas. These systemic resistant responses to N₂O₅ were found unique among air-plasma-generated species such as ozone (O₃) and nitric oxide (NO)/nitrogen dioxide (NO₂). Our results provide new insights into understanding of plant physiological responses to air-derived reactive species, in addition to facilitating the development of plasma applications in agriculture.

Abstract The development of a nonconventional nitrogen fertilizer, which can be fixed in agricultural fields using decentralized renewable energy sources, presents a feasible solution for sustainable on‐site nitrogen fixation and fertilization. This study focuses on plasma‐generated dinitrogen pentoxide (N₂O₅) as a prospective mediator for the on‐site nitrogen fertilization, allowing nitrogen fertilization directly into culture media. Basal dinitrogen pentoxide fertilization demonstrated almost 100% dinitrogen pentoxide dissolution efficiency as nitrate in a culture medium and nitrogen fertilization effect on plant growth without explicit symptoms of damage. Top‐dressing of dinitrogen pentoxide was also an efficient method for transferring nitrogen into the soil as nitrate, which improved plant growth and suppressed nitrogen deficiency symptoms, while overdose caused adverse effects.

Abstract Gas–liquid interfacial plasmas (GLIPs), specifically atmospheric-pressure plasmas (APPs) interacting with liquids, have garnered global interest for potential applications across various fields where reactive oxygen and nitrogen species (RONS) in both the gas and liquid phases could play a key role. However, APP-induced gas- and liquid-phase chemical reactions display spatially nonuniform features and involve a number of species; thus, they are extremely complicated and have not been fully understood and controlled. Herein, our primary focus is centered on elucidating RONS transport processes in GLIPs without direct plasma-liquid contact to reduce the complexity of this mechanism. Firstly, this review delineates the simplified transport models commonly found in general GLIP systems, including: (1) the transport of remotely generated gas-phase RONS to the liquid phase; (2) liquid-phase diffusion governing dissolution into the liquid phase and volatilization loss to the gas phase; and (3) chemical reactions in the liquid phase governing the generation and loss of short-lived RONS. Second, we delve into RONS transport using our laboratory-built plasma devices, aimed at sterilizing plant pathogens, interpreting results in line with the relevant transport models to aid the comprehension of the heterogeneous transport of RONS. Third, we discussed the innovative control of the plasma reaction process in the gas phase required to selectively synthesize N₂O₅, which is highly reactive at the gas–liquid interface. Finally, future prospects for the efficient utilization of unique reactions at the plasma/gas–liquid interface are discussed.

Abstract Exposure to N₂O₅ generated by plasma technology activates immunity in Arabidopsis through tryptophan metabolites. However, little is known about the effects of N₂O₅ exposure on other plant species. Sweet basil synthesizes many valuable secondary metabolites in its leaves. Therefore, metabolomic analyses were performed at three different exposure levels [9.7 (Ex1), 19.4 (Ex2) and 29.1 (Ex3) μmol] to assess the effects of N₂O₅ on basil leaves. As a result, cinnamaldehyde and phenolic acids increased with increasing doses. Certain flavonoids, columbianetin, and caryophyllene oxide increased with lower Ex1 exposure, cineole and methyl eugenol increased with moderate Ex2 exposure and l-glutathione GSH also increased with higher Ex3 exposure. Furthermore, gene expression analysis by quantitative RT-PCR showed that certain genes involved in the syntheses of secondary metabolites and jasmonic acid were significantly up-regulated early after N₂O₅ exposure. These results suggest that N₂O₅ exposure increases several valuable secondary metabolites in sweet basil leaves via plant defense responses in a controllable system.

Abstract Homologous recombination (HR) repairs DNA damage including DNA double-stranded breaks and alterations in HR-related genes results in HR deficiency. Germline alteration of HR-related genes, such as BRCA1 and BRCA2, causes hereditary breast and ovarian cancer (HBOC). Cancer cells with HR deficiency are sensitive to poly (ADP-ribose) polymerase (PARP) inhibitors and DNA-damaging agents. Thus, accurately evaluating HR activity is useful for diagnosing HBOC and predicting the therapeutic effects of anti-cancer agents. Previously, we developed an assay for site-specific HR activity (ASHRA) that can quantitatively evaluate HR activity and detect moderate HR deficiency. HR activity in cells measured by ASHRA correlates with sensitivity to the PARP inhibitor, olaparib. In this study, we applied ASHRA to lymphoblastoid cells and xenograft tumor tissues, which simulate peripheral blood lymphocytes and tumor tissues, respectively, as clinically available samples. We showed that ASHRA could be used to detect HR deficiency in lymphoblastoid cells derived from a BRCA1 pathogenic variant carrier. Furthermore, ASHRA could quantitatively measure the HR activity in xenograft tumor tissues with HR activity that was gradually suppressed by inducible BRCA1 knockdown. The HR activity of xenograft tumor tissues quantitatively correlated with the effect of olaparib. Our data suggest that ASHRA could be a useful assay for diagnosing HBOC and predicting the efficacy of PARP inhibitors.

Fixing atmospheric nitrogen for use as fertilizer is a crucial process in promoting plant growth and enhancing crop yields in agricultural production. Currently, the chemical production of nitrogen fertilizer from atmospheric N2 relies on the energy-intensive Haber-Bosch process. Therefore, developing a low-cost and easily applicable method for fixing nitrogen from the air would provide a beneficial alternative. In this study, we tested the utilization of dinitrogen pentoxide (N2O5) gas, generated from oxygen and nitrogen present in ambient air with the help of a portable plasma device, as a nitrogen source for the model plant Arabidopsis thaliana. Nitrogen-deficient plants supplied with medium treated with N2O5, were able to overcome nitrogen deficiency, similar to those provided with medium containing a conventional nitrogen source. However, prolonged direct exposure of plants to N2O5 gas adversely affected their growth. Short-time exposure of plants to N2O5 gas mitigated its toxicity and was able to support growth. Moreover, when the exposure of N2O5 and the contact with plants were physically separated, plants cultured under nitrogen deficiency were able to grow. This study shows that N2O5 gas generated from atmospheric nitrogen can be used as an effective nutrient for plants, indicating its potential to serve as an alternative nitrogen fertilization method for promoting plant growth.

Abstract We have developed a new liquid‐phase noncatalytic selective oxidation of polyhydric alcohols such as glycerol. This method involves the use of a nonthermal atmospheric‐pressure plasma instead of precious‐metal catalysts. We found that noncatalytic selective oxidation of glycerol achieved a conversion comparable to that achieved by gold‐catalyzed oxidation, and the desired glyceric acid, which is a pharmaceutical raw material, was obtained. When the solution pH was changed from strongly alkaline to neutral, the main reaction switched from the one that occurs in the presence of gold catalysts to the one that occurs in the presence of platinum catalysts. These results suggest that the reactive oxygen species generated by nonthermal atmospheric‐pressure plasma irradiation vary depending on the solution pH.

Abstract Large-scale integration of quantum-dot devices is essential for realizing various quantum devices. Graphene-based quantum dots provide a promising platform for spin qubits because of their low nuclear spin density and weak spin-orbit interaction. However, the integration of graphene-based quantum dots remains a challenge. Here, we demonstrate the scalable fabrication of graphene nanoribbon-based quantum-dot devices using a nickel nanobar technique. Fine structures formed in the middle of the nanoribbons exhibit quantum-dot behavior, and more than 56% of devices fabricated on the same substrate show Coulomb diamond features, indicating that large-scale integration of graphene nanoribbon quantum-dot devices is possible with our method. Cryogenic measurements reveal orbital-level spacings between the ground and excited states that are stable up to high-temperature conditions of ~20 K. We explain this stability in terms of the very fine structures formed in the middle of the nanoribbons and their relatively low effective mass.

Abstract Herein, we developed a near-invisible solar cell through a precise control of the contact barrier between an indium tin oxide (ITO) electrode and a monolayer tungsten disulfide (WS₂), grown by chemical vapor deposition (CVD). The contact barrier between WS₂ and ITO was controlled by coating various thin metals on top of ITO (M_x/ITO) and inserting a thin layer of WO₃ between M_x/ITO and the monolayer WS₂, which resulted in a drastic increase in the Schottky barrier height (up to 220 meV); this could increase the efficiency of the charge carrier separation in our Schottky-type solar cell. The power conversion efficiency (PCE) of the solar cell with the optimized electrode (WO₃/M_x/ITO) was more than 1000 times that of a device using a normal ITO electrode. Large-scale fabrication of the solar cell was also investigated, which revealed that a simple size expansion with large WS₂ crystals and parallel long electrodes could not improve the total power (P_T) obtained from the complete device even with an increase in the device area; this can be explained by the percolation theory. This problem was addressed by reducing the aspect ratio (width/channel length) of the unit device structure to a value lower than a critical threshold. By repeating the experiments on this optimized unit device with an appropriate number of series and parallel connections, P_T could be increased up to 420 pW from a 1-cm² solar cell with a very high value (79%) of average visible transmission (AVT).

Reactive nitrogen species (RNS) play an important role in plant immunity as signaling factors. We previously developed a plasma technology to partially convert air molecules into dinitrogen pentoxide (N₂O₅), an RNS whose physiological action is poorly understood. To reveal the function of N₂O₅ gas in plant immunity, Arabidopsis thaliana was exposed to plasma-generated N₂O₅ gas once (20 s) per day for 3 days, and inoculated with Botrytis cinerea, Pseudomonas syringae pv. tomato DC3000 (Pst), or cucumber mosaic virus strain yellow (CMV(Y)) at 24 h after the final N₂O₅ gas exposure. Lesion size with B. cinerea infection was significantly (P < 0.05) reduced by exposure to N₂O₅ gas. Propagation of CMV(Y) was suppressed in plants exposed to N₂O₅ gas compared with plants exposed to the air control. However, proliferation of Pst in the N₂O₅-gas-exposed plants was almost the same as in the air control plants. These results suggested that N₂O₅ gas exposure could control plant disease depending on the type of pathogen. Furthermore, changes in gene expression at 24 h after the final N₂O₅ gas exposure were analyzed by RNA-Seq. Based on the gene ontology analysis, jasmonic acid and ethylene signaling pathways were activated by exposure of Arabidopsis plants to N₂O₅ gas. A time course experiment with qRT-PCR revealed that the mRNA expression of the transcription factor genes, WRKY25, WRKY26, WRKY33, and genes for tryptophan metabolic enzymes, CYP71A12, CYP71A13, PEN2, and PAD3, was transiently induced by exposure to N₂O₅ gas once for 20 s peaking at 1–3 h post-exposure. However, the expression of PDF1.2 was enhanced beginning from 6 h after exposure and its high expression was maintained until 24–48 h later. Thus, enhanced tryptophan metabolism leading to the synthesis of antimicrobial substances such as camalexin and antimicrobial peptides might have contributed to the N₂O₅-gas-induced disease resistance.

Abstract The recent global pandemic of Corona Virus Disease-19 has impacted all aspects of society, producing a growing demand for a powerful virus inactivation method. To assess a potential and mechanism of human coronavirus inactivation using atmospheric pressure plasma (APP) technology, replication of a human coronavirus (HCoV-229E) after He + H₂O APP plume exposure was evaluated using rhesus monkey kidney epithelial cells. The HCoV-229E titers were reduced by 3 log₁₀TCID₅₀ after the APP exposure for 30 s, showing a strong virus-inactivation efficacy of the APP. It was experimentally verified that the APP produced the liquid-phase reactive oxygen and nitrogen species (RONS) at high rates [e.g. ^•OH: ∼1.7 nmol s⁻¹, H₂O₂ (including H₂O₂ precursors): ∼9.2 nmol s⁻¹, NO₂⁻ (including NO₂⁻ precursors): ∼3.3 nmol s⁻¹]. However, an administration of H₂O₂ with NO₂⁻ failed to inactivate the virus and only Mn type superoxide dismutase among several RONS scavengers for ^•OH, HO₂^•/O₂^{•−, 1}O₂, and ^•NO/^•NO₂ was significantly effective for the recovery of the APP-induced decrease in the viral titers. This suggests O₂^•−-related chemical reaction in a network of interconnected reactions induced by the APP exposure is very important for the APP-induced virus inactivation. These results provide new insight into a more efficient inactivation method of human coronavirus using APPs.

<title>Abstract</title> Nitrogen is a very common element, comprising approximately 78% of Earth’s atmosphere, and is an important component of various electronic devices while also being essential for life. However, it is challenging to directly utilize dinitrogen because of the highly stable triple bond in this molecule. The present review examines the use of non-equilibrium plasmas to generate controlled electron impacts as a means of generating reactive nitrogen species (RNS) with high internal energy values and extremely short lifetimes. These species include ground state nitrogen atoms, excited nitrogen atoms, etc. RNS can subsequently react with oxygen and/or hydrogen to generate new highly reactive compounds and can also be used to control various cell functions and create new functional materials. Herein, plasma-processing methods intended to provide RNS serving as short-lived precursors for a range of applications are examined in detail.

Abstract Inspired by the ideas of many authors, we provide insight on state-of-the-art potential technologies for the prevention and prediction of infectious diseases before they spread. This review also surveys virus sterilization with ultraviolet light and low temperature plasma technologies. Researchers in the various fields of medicine, materials, electronics, and plasma sciences have addressed increasingly challenging demands and the discussion encompasses the major challenges in societies that are faced with the threat of infectious diseases. In addition, technologies that use nanomaterials are evaluated for infection prevention and hygiene purposes. Advances in biomedical diagnostics for health care in terms of complementary metal-oxide-semiconductor transistors-based devices and telemetry for health monitoring are also reviewed.

Abstract The very early nucleation stage of a transition metal dichalcogenide (TMD) was directly observed with in-situ monitoring of chemical vapor deposition and automated image analysis. Unique nucleation dynamics, such as very large critical nuclei and slow to rapid growth transitions, were observed during the vapor–liquid–solid (VLS) growth of monolayer tungsten disulfide (WS₂). This can be explained by two-step nucleation, also known as non-classical nucleation, in which metastable clusters are formed through the aggregation of droplets. Subsequently, nucleation of solid WS₂ takes place inside the metastable cluster. Furthermore, the detailed nucleation dynamics was systematically investigated from a thermodynamic point of view, revealing that the incubation time of metastable cluster formation follows the traditional time–temperature transformation diagram. Quantitative phase field simulation, combined with Bayesian inference, was conducted to extract quantitative information on the growth dynamics and crystal anisotropy from in-situ images. A clear transition in growth dynamics and crystal anisotropy between the slow and rapid growth phases was quantitatively verified. This observation supports the existence of two-step nucleation in the VLS growth of WS₂. Such detailed understanding of TMD nucleation dynamics can be useful for achieving perfect structure control of TMDs.

Despite successful clinical application of non-equilibrium atmospheric pressure plasma (APP), the details of the molecular mechanisms underlying APP-inducible biological responses remain ill-defined. We previously reported that exposure of 3T3L1 cells to APP-irradiated buffer raised the cytoplasmic free Ca2+ ([Ca2+]i) concentration by eliciting Ca2+ influx in a manner sensitive to transient receptor potential (TRP) channel inhibitors. However, the precise identity of the APP-responsive channel molecule(s) remains unclear. In the present study, we aimed to clarify channel molecule(s) responsible for indirect APP-responsive [Ca2+]i rises. siRNA-mediated silencing experiments revealed that TRPA1 and TRPV1 serve as the major APP-responsive Ca2+ channels in 3T3L1 cells. Conversely, ectopic expression of either TRPA1 or TRPV1 in APP-unresponsive C2C12 cells actually triggered [Ca2+]i elevation in response to indirect APP exposure. Desensitization experiments using 3T3L1 cells revealed APP responsiveness to be markedly suppressed after pretreatment with allyl isothiocyanate or capsaicin, TRPA1 and TRPV1 agonists, respectively. APP exposure also desensitized the cells to these chemical agonists, indicating the existence of a bi-directional heterologous desensitization property of APP-responsive [Ca2+]i transients mediated through these TRP channels. Mutational analyses of key cysteine residues in TRPA1 (Cys421, Cys621, Cys641, and Cys665) and in TRPV1 (Cys258, Cys363, and Cys742) have suggested that multiple reactive oxygen and nitrogen species are intricately involved in activation of the channels via a broad range of modifications involving these cysteine residues. Taken together, these observations allow us to conclude that both TRPA1 and TRPV1 channels play a pivotal role in evoking indirect APP-dependent [Ca2+]i responses.

More details Close

The nitrogen-atom endohedral fullerene (N@C₆₀) with relatively higher purity [molar concentration ratio of N@C₆₀ to pristine fullerene (C₆₀)] has been synthesized by controlling plasma ion irradiation energy (E_i) and C₆₀ behavior. We have examined the relationship between the synthesis purity of N@C₆₀ and E_i which is controlled by changing the substrate bias voltages (V_sub) and gas pressure (P_N2) during the plasma irradiation process. It has been clarified that there is an optimum condition of the nitrogen plasma for the high-purity synthesis of N@C₆₀, which consists of the high-density nitrogen-molecular ions (N₂⁺) with suitable E_i from 40 to 80 eV. In addition, control of C₆₀ behavior contributes to an increase in the reaction between C₆₀ and N₂⁺ to form N@C₆₀, resulting in the synthesis of N@C₆₀ with the highest purity of 0.56 % in the world.

More details Close

A gas-liquid interfacial discharge plasma is used for the DNA-associated synthesis of water-soluble gold nanoparticles (AuNPs) by reducing Au ions in aqueous chloroauric acid trihydrate. The plasma is generated by a pulse power source, which can avoid the instability of DC discharges at high pressures. The high discharge current (～ampere) offers a basis for the high rate synthesis of AuNPs. Single-stranded DNA is used as a stabilizing agent since the DNA molecules can be bound to the Au surface. The AuNP size and morphology can be tuned by the DNA concentration. The ability of DNA for stabilizing AuNPs is found to decrease with increasing the DNA length. We also synthesize AuNPs associated with different-base DNA consisting of guanine, adenine, cytosine, and thymine (denoted as dG₃₀, dA₃₀, dC₃₀, and dT₃₀). It is found that dG₃₀ and dA₃₀ have the stronger stabilizing ability for AuNPs than dT₃₀ and dC₃₀ by comparing the intensities of surface plasmon resonance (SPR) peaks of AuNPs after extracting them from as-synthesized samples by centrifugation.

Plasma flow velocity shears parallel and perpendicular to magnetic field lines are independently controlled and superimposed by a modified plasma-synthesis method with concentrically three-segmented electron and ion emitters. The fluctuation amplitude of a drift wave with an azimuthal mode number m = 3 is observed to increase with increasing parallel shear strength in the absence of a perpendicular shear. When the perpendicular shear is superimposed on the parallel shear, the drift wave with m = 3 is found to transform into that with m = 2. Furthermore, the parallel shear strength required for excitation of the drift wave increases with a decrease in the azimuthal mode number. Based on these results, superposition of the parallel and perpendicular shears can affect characteristics of the drift wave through variation of the azimuthal mode number. These phenomena can be verified by theoretical calculations of the growth rate of the drift wave using an eigenmode analysis.

Selectively launched electromagnetic waves with left- and right-handed polarizations for m = 0, +1, and -1 modes are investigated in terms of polarization reversal around an electron cyclotron resonance (ECR) region in inhomogeneously magnetized plasmas, where m is an azimuthal mode number. It is observed for the first time that a left-handed polarized wave for m = 0 mode is absorbed near the ECR point as a result of the polarization reversal in the axial direction. Dispersion analysis in bounded plasmas can explain this quantitatively. For m = +1 and -1 modes, on the other hand, polarization reversal occurs along the radial axis, i.e., wave polarization for m = +1 mode is right-handed (left-handed for m = -1 mode) around the central area and left-handed (right-handed for m = -1 mode) around the peripheral area of the cross section of the plasma column. Furthermore, we investigate plasma-potential structures formed by ECR of high-power m = +1 and -1 waves and, for the first time, demonstrate control of the plasma-potential structure by changing the azimuthal mode, i.e., a positive potential hill is formed near the ECR point around the central and peripheral areas for m = +1 and -1 modes, respectively.

The encapsulation of C₆₀ molecules inside double-walled carbon nanotubes (DWNTs) is realized by means of a plasma ion-irradiation method. Transmission electron microscopy observations confirm that DWNTs have been filled with C₆₀ fullerenes having amorphous morphology. More importantly, electrical transport measurements indicate that C₆₀-encapsulated metallic DWNTs exhibit a novel negative differential resistance behavior.

The effects of ion flow velocity shears parallel and perpendicular to the magnetic-field lines, which are precisely controlled by a segmented electrode, are investigated in open-ended magnetized plasmas. The perpendicular flow velocity shears are demonstrated to suppress drift-wave, flute, and ion-cyclotron instabilities. On the other hand, parallel flow velocity shears are observed to destabilize D'Angelo mode, drift-wave, and ion-cyclotron instabilities depending on the sign of the parallel shear. The combined effects of the parallel and perpendicular flow shears will be important for controlling instabilities in magnetized plasmas.

More details Close

The external and independent control of parallel and perpendicular flow shears in collisionless magnetized plasmas are realized using two newly-developed plasma sources. The ion flow velocity shears parallel to the magnetic-field lines are then observed to destabilize not only the D'Angelo mode but also the drift-wave instability depending on the sign of the parallel shear in the absence of field-aligned electron drift flow in laboratory experiments. On the other hand, perpendicular ion flow velocity shears are demonstrated to suppress the drift-wave and the ion-cyclotron instabilities, and furthermore, these suppressions are found to take place independently of the sign of the perpendicular shear.

The polarization reversal from a left-hand (LHPW) to a right-hand polarized wave (RHPW) and the resultant electron cyclotron damping of the LHPW are experimentally observed for the first time. Our experimental results indicate that the polarization reversal arises simultaneously with the conversion of the propagation angle of the wave, in which finite-plasma boundary conditions are considered to be inherent.

Laboratory investigations on the formation of space-related electric fields have been performed using collisionless magnetized-plasma flows. In a set of experments, potential differences are externally applied along magnetic-field lines, different plasmas come into contact with each other under the currentless condition, a high-speed plasma flow is injected into a region of converging manetic-field lines, large-amplitude electron plasma waves are generated in a uniform magnetic field, and local electron-cyclotron resonances occur in various kinds of nonuniform magnetic fields. It is found that the elcetric field is formed in the region of density gradient, a U-shaped double layer (DL) is accompaned by ion-cyclotron oscillations, a DL is formed in the currentless system, and that an electron local-plug results in the formation of a potential dip and hump with a scale length of the order of Debye length. Electron- and ion-acceleration electric fields with a scale lengths of a magnetic-field gradient are also found to be formed by passing ions and electrons through nonuniform magnetic fields, respectively.

<p>Fine bubbles generated by plasma in water that we named as "Plasma Fine Bubbles," have high potential to generate long-life ultrafine bubbles due to electrical charges. It is shown that the residual bubbles formed by collapse of streamer gas channels which show a similar process of cavitation bubbles in various points such as growth, shrink, collapse, rebound, and fragmentation. There are also introductions about ultrafine bubbles measured by a dynamic laser scattering method, amount of electrical charge of plasma fine bubbles estimated by analyzing their movements under application of an intense electric field strength, evidence of hydrogen gas generation in laser/spark induced bubbles and a distinguishing method for between gas bubbles and solid particles.</p>

Cavitation bubbles were generated by an underwater shock wave and formation of microjets in the collapse process were visualized by a high-speed camera. The directions of the microjets showed the same direction of the initial shock wave propagation. These results imply that the direction of the microjets were affected by the compression wave not expansion wave which was generated by reflection at an interface between water and air.

This paper describes historical overview and recent activity on “plasma electrochemistry”, which involves materials processing with plasmas in contact with liquids. Nano-materials synthesis and organic-pollutant decomposition are the most active application areas. The most important part of the plasma electrochemistry is the plasma/liquid interface. The physicochemical processes near the plasma/liquid interface have been gradually clarified through experiments and numerical simulations. These are briefly described in this paper together with future issues for understanding effects of electric double layer and nano-scale steep density gradient.

Recently, plasma applications for bio-medical field are investigated. In this study, for the purpose of development of the minimally invasive gene transfection using discharge plasmas, as a first step, DNA is encapsulated into carbon nanotubes in order to deliver the DNA without damage. In addition, for the purpose of improving the transfection efficiency, the discharge plasma including hydroxyl radical is irradiated for a few second to the cell mixed with a fluorescent material. As a result, the transfection efficiency becomes high (30%) and viability is more than 90%.

Publisher: The Japan Society of Mechanical Engineers

More details Close

Highly-ordered periodic structures of the gold nanoparticles (AuNPs) are formed by transcribing the plasma structure to the surface of the liquid, where the spatially selective synthesis of the AuNPs is realized. Furthermore, the plasma structure is controlled by using a ring or disk electrode under the strong magnetic fields up to 4 tesla. The ring structure of the nanoparticles is found to be formed in accordance with the shadow region of the ring electrode. It is found that the AuNPs are synthesize by the reduction effect of the hydrogen radical via irradiation of neutral radical of the plasma and are destroyed by the oxidation effect of the fluorine radical via high-energy plasma ion irradiation.

放電プラズマ窒素固定の研究は，無尽蔵原料と自然エネルギーで価値ある物質を創成できるため，化石燃料に依存しない持続可能な社会の実現に寄与する．本研究では，高効率なプラズマ窒素固定の実現に重要な，高圧下での体積充填的な振動励起窒素生成を目指し，申請者独自の過電圧生成電離波による非自己維持放電プラズマの生成法を研究する．非自己維持放電プラズマは，放電電力の多くを窒素解離の活性化エネルギー低減に寄与できるとされる振動励起窒素生成に利用できる可能性があり，電力効率の高い窒素固定の鍵となる可能性がある．さらに，大気圧下に近い高圧下での過電圧生成電離波は空間一様な電離に寄与できると考えており，反応体積を確保した実用的な窒素固定実現に向け重要である．今年度は特に非自己維持放電プラズマの生成条件を詳細に検討し，高振動励起窒素生成とその観測技術の向上に注力した．その結果，非自己維持放電用の直流電圧の重畳印加により，発光分光法から回転温度が100K以下の上昇の時，ラマン散乱計測から1000K程度の振動温度上昇が得られる条件が判明した．0.1気圧における非自己維持放電の各パラメータ調整の結果，重畳直流電圧の増加と共に振動温度が非線形的に上昇し，本研究の非自己維持放電プラズマを用いることで，選択的な振動励起が実現できることを実験的に示した．この結果は，活性化エネルギーの低い窒素解離反応が期待できる高振動励起窒素（v>12）の効率的生成が期待できるプラズマ源となっている可能性を示しており，効率的なプラズマ窒素固定の実現に向け有意義な進展が得られた．過電圧電離波生成に関しては，当初の予定通り絶縁破壊の遅延制御の有効性が期待されるという知見が得られた．

The purpose of this study is to distinguish reactive species generated in gas-liquid interfacial plasmas by their lifetimes, to clarify the generation and extinction processes of "extremely short-lived reactive species", which react and self-dissolve in less than one second, and to experimentally clarify their effects on biomolecules and cells. The research was promoted by constructing an "atmospheric pressure plasma apparatus with high-speed liquid flow". As a result, we succeeded in the time-resolved measurement of extremely short-lived reactive species (OH radicals and nitrite precursors) in high-speed liquid flow for the first time, and constructed a reaction diffusion model that takes into account the surface localization distribution of OH radicals and consumption by long-lived reactive species. In addition, the effects of the extremely short-lived active species on biomolecules (amino acids) were also clarified.

When rice seeds were irradiated with atmospheric plasma, the occurrence of "Bakanae disease" and bacterial damping-off disease in rice seedlings was suppressed. Irradiation of Arabidopsis thaliana with plasma reduced the level of virus multiplication. It has been known that reactive oxygen species act as a signaling molecule for plant immune system. Interestingly, the comprehensive analysis of reactive molecules produced by atmospheric plasma irradiation indicated that peroxynitrite (HOONO) and pernitric acid (HOONO2), which have antimicrobial activity, and N2O5 accumulated in gas phase, and NO3- was detected in liquid phase. Furthermore, in plants irradiated with atmospheric plasma, defense-related gene expression: PR1, PDF1.2 and ChiB, was significantly induced, suggesting that plant immune system seems to be activated by irradiation of plants with atmospheric plasma.

The charge transport mechanism in water was clarified by constructing a measurement system of the electric potential and by analyzing an equivalent circuit model proposed in this study. Also, it was clarified that the micro bubbles generated by underwater plasma moved with the velocity of higher than 50 m/s by the electric field, and its electrical charge quantity of the bubbles was estimated. Furthermore, a device which gives only electrical charge stimuli without chemical stimuli to the cells was developed and it was clarified that the actin filaments in the cells were elongated by the charged stimuli. Also, we clarified the generation mechanism of the directional microjet aiming at injecting charges to the inside of the cells and propagation mechanism of the negative streamer, by developing the visualization method of the small pressure.

We have challenged to create “ultrasensitive cell-based sensor array” which can detect the temporal-spatial distribution of infinitesimal heterogeneous stimuli generated by the atmospheric pressure non-equilibrium plasmas. We measured the 2-dimensional distribution of oxidation stimulus (reactive species), electric stimulus (charged particles), pressure stimulus (shock wave) which were generated in the solution irradiated with atmospheric pressure plasma jet or in-liquid micro plasma. Furthermore, we arrayed the cells which have overexpressing channels responding with each stimulus, and measured the 2-dimentional distribution of fluorescence intensity proportional to the concentration of calcium ion or gene-simulated fluorescent molecule in the cells. As a result, we have demonstrated that the cells can act as the sensor arrays for oxidation stimulus, electric stimulus, and pressure stimulus.

Dental implants are widely used as highly predictive treatments, however, there is no fundamental solution to peri-implantitis. Therefore, in this research, we aimed to construct a completely new comprehensive implant recovery system for peri-implantitis by selecting the site and time and applying radicals using the latest engineering technology. In this study, we first developed visible light responsive titanium oxide and atmospheric pressure plasma jet irradiation equipment that are most suitable for the implant recovery systems. Using these, we were able to acquire the basic technology to construct an implant recovery system that can be reliably and safely restored without removal in the oral cavity.

Recently, non-equilibrium atmospheric pressure plasma (APP) emerged to exert diverse biological responses, though the underlying mechanisms remained to be determined. This study aimed to explore precise mechanisms underlying of plasma-inducible increases in intracellular Ca2+ concentration in insulin-responsive cells, which has been recently discovered by our research group. Our results demonstrated that increases in intracellular Ca2+ are induced by continuous low-dose O2－/ ONOO－ supply, which is mediated through TRP channel activation. Our findings indicate the potential of APP for regulating insulin-responsive cell functions. Moreover, APP showed inhibitory actions on adipogenic differentiation of 3T3L1 cells. Together, these results demonstrate that APP-induced TRP channel activation is intimately involved in various cellular responses triggered by APP exposure.

Irradiating ultra intense ultrashort laser pulses on nano size cluster targets, protons are accelerated due to Coulomb explosion, the energies of which are of the order of a few MeV. In terms of the reactions between Lithium and the protons, neutrons are generated. optimizing the laser and target parameters, we maximize the coupling efficiency of neutron yields. In particular, the cluster targets are made of two or three atomic components in order to produce quasi-monoenergetc protons. The resultant neutrons are expected to have relatively low temperatures lower than a few 100 keV because the endothermic reactions.

In order to create novel photoelectric conversion devices which can generate multiple excitons in the full-spectrum light region, we synthesized the n-type semiconducting carbon nanotube (CNT) which can extract the excitons from the nano-graphene or transition metal dichalcogenide (TMD), and then, fabricated the CNT/graphene・TMD photoelectric conversion devices. In the beginning, it was clarified that the nano-graphene can be formed on the CNT surface by irradiating the CNT with the methane plasma. We tried to dope nitrogen or cesium ions into the CNT by plasma ion irradiation method, and found that the n-type semiconducting CNT can be synthesized. Furthermore, we fabricated the CNT/TMD photoelectric conversion device and succeeded in photovoltaic power generation using the CNT/TMD device for the first time.

In the beginning, it has been experimentally verified that micro-scale plasma was generated by applying a pulse voltage to coaxial type thin electrode and had the capability to enhance the cellular uptake of drugs and genes. Next, investigation of effects of separated plasma-derived stimuli on drug uptake showed that plasma-produced short-lived reactive species contribute to the drug uptake. Furthermore, it is clarified that relatively short-lived reactive species (i.e., deactivated within approximately 10 min) in plasma-irradiated saline induced physiologically relevant calcium ion influx through ion channel on cell membrane, which triggers activation of gene and drug uptake.

Plasma consists of a variety of reactive species (ions, electrons, radicals and emitting photons). In discharge plasmas, these reactive species are generated via ionization and dissociation of gaseous molecules through collisions with accelerated electrons. Due to enhanced reactivity of these reactive species, plasma are indispensable as key manufacturing technology for advanced industries and eventually have taken a role as core technology to support the state-of-the-art advancement of scientific frontiers. This project led the worldwide research activities, and created the field "Plasma Medical Innovation". A key significance of this study is to establish unique schemes to evolve the interdisciplinary field of plasma science, medical science and molecular biology.

Two functions of the plasma generated reactive species for agricultural applications, the germination suppression of pathogenic conidia and the induction of defense related genes of rice seeds, are experimentally investigated. The germination suppression effect is enhanced by the water molecular fraction increase in plasma, correlating with hydroxy radical density in the plasma effluent and nitrate ion concentration in the conidia suspension. On the other hand, the gene expression degree of the defense related genes of rice seeds are significantly increased under a certain plasma effluent exposure condition and are varied simultaneously with the mixture variation of the reactive species. The difference of the reactive species correlated with the germination suppression and the defense related genes indicates the feasibility to switch those functions by the reactive species control in the plasma effluent.

Synthesis of vertically standing graphene from single-walled carbon nanotube (SWNTs) is realized through the adjustment of ion energy coming to the substrate during plasma CVD. The detailed electrical measurements reveal that the vertically standing graphene on SWNTs acts as a quantum dot for the carrier transport of SWNTs with high thermal stability. Decoration of nanoparticles on the vertically standing graphene is also realized aiming for the molecular motor application. Clear plasmonic response can also be observed from the nanoparticles decorated on the vertically standing graphene. Since the novel hybrid nanomaterial, nanoparticle decorated-vertically standing graphene/SWNTs, includes optically responsible and room temperature stable quantum dot structure, this novel material can be useful for wide variety of optoelectrical applications.

For the purpose of arrangement control of heat-fragile nitrogen-atom endohedral fullerene (N@C60), we have performed the encapsulation of N@C60 into carbon nanotube (CNT) using a droplet jet plasma. First, we dissolved empty C60 in toluene and irradiated the C60 to CNT using the plasma. As a result, we have been successful in encapsulating the C60 ions into CNT. Second, highly-concentrated N@C60 was irradiated to CNT in the same way as C60, however, N@C60 cannot be detected in CNT. By investigating the effect of ultraviolet light (UV) on N@C60, it is found that the N@C60 was decomposed by the UV in proportion to the UV irradiation time, and therefore, we have identified the causation of absence of N@C60 in CNT as the instability of N@C60 by the irradiation of UV emitted from the plasma.

Electron temperature gradient (ETG) perpendicular to magnetic field lines is formed by superimposing high-temperature electrons of an electron cyclotron resonance (ECR) plasma upon low-temperature thermionic electrons. The formed ETG is found to excite a high-frequency fluctuation (ETG mode), and also, to stimulate a low-frequency fluctuation (drift-wave mode) excitement via multi-scale nonlinear interaction, which ultimately causes ETG mode energy to be transferred to the drift-wave mode. Furthermore, the strong E×B velocity shear is demonstrated to suppress the ETG mode and drift-wave mode, experimentally.

A transfer-free method for growing graphene directly on a SiO2 substrate has been realized for the first time by plasma chemical vapor deposition (PCVD). Using this method, high-quality single-layer graphene sheets can be selectively grown between a Ni film and the SiO2 substrate. Systematic investigations reveal that the relatively thin Ni layer and PCVD are critical to the success of this unique method of graphene growth. Selective edge functionalization of graphene is also realized by mild plasma treatment. The electrical transport properties of graphene can be tuned from p-to n-type with our developed mild plasma treatment.

We have produced alkali-metal-and fullerene-encapsulated single-walled carbon nanotubes (Cs@SWNTs and C_<60>@SWNTs) by plasma ion irradiation, and investigated their electronic transport properties in comparison with those of pristine SWNTs by adopting field effect transistor (FET) configurations. Although it is confirmed that pristine SWNTs and C_<60>@SWNT5 show a p-type transport property, Cs@SWNT5 clearly exhibit an n-type transport property, which is explained in terms of electron transfer from encapsulated Cs atoms toward the surrounding SWNTs. These results signify that the encapsulation of atoms or molecules inside single-walled carbon nanotubes by plasma ion irradiation has potential for controlling the electronic structure of SWNTs. The basic characteristics of gas sensor based on C_<60> (or SWNTs) and polymer composite material were observed. The composite material of polyethylene glycol (PEG)-grafted SWNTs (PEG-SWNTs) and conductive polymer: polyaniline is coated on to a glass plate with 4 comb-like electrodes by spin coater. PEG-SWNTs are synthesized by heat-treatment of toluene solution including Azo-PEG (macro Azo initiators). According to the measurement, it turned out that the change at time of impedance for the acetone and the ethanol was different clearly. Especially, acetic acid is observed the decrease in the impedance which originates in carboxyl radical, and shows a reaction which is obviously different from other materials. Therefore, it turned out this sensor to provide the function for the specific gas detection.

1.平成16年度までは,容量結合支援誘導結合型高周波放電による高気圧反応性プラズマ発生装置を用いて,高気圧プラズマでヘキサメチルジシロキサンHMDSOを使用した球殻構造ナノスケールシリコン(Si)物質(Siフラーレン)形成実験を行ってきたが,HMDSO中の酸素,炭素が不純物として残留し,Siフラーレン形成が困難となる問題が発生したため,平成17年度は新しいSiフラーレン形成方法として,電子銃を利用したSiプラズマの生成を試み,それを用いた新規原子内包Siフラーレンの形成実験を行った. 2.直径14cmのステンレス製真空容器内部に電子銃を設置し,熱電子をSi固体に照射することでSiプラズマを生成する.Siプラズマは電子銃からの電子電流によって制御可能である. 3.本研究ではSiクラスターに内包させる物質として,ガス原子と金属原子を対象とした.ガス原子としてはアルゴン(Ar)を用い,装置中心に設置したヘリカルアンテナに高周波(13.56MHz)電力供給し誘導結合プラズマを生成することで,Siクラスターに作用させた.一方,金属原子としてはタングステン(W)を用い,ヘリカルアンテナ上部に設置したWグリッドへの負バイアス印加によるスパッタ効果を利用して,W原子をSiクラスターへ作用させた. 4.Arガスを導入せずにSiプラズマのみを用いて基板へ堆積した物質の質量分析を行ったところ,質量数が28の整数倍である純粋なSiクラスターの形成が確認された. 5.Arガスを導入した場合には,純粋なSiクラスターに加えて,質量数が28の整数倍から高質量側に12だけシフトした物質が質量数300〜600の範囲で検出された.この質量スペクトルのシフトは,質量数が12,40,68,96のいずれかの物質がSiクラスターに作用したためと考えられる.Arガス圧力の増加によりシフト成分が検出され,ヘリウムやクリプトンなど他の希ガスを用いた場合には質量数がシフトした物質は検出されなかったことから,Ar(質量数40)がSiクラスターに作用した結果であると考えている. 6.Arガスを導入して形成したSiクラスターの組成分析を行った結果,Ar成分の含有を示すスペクトルピークが検出され,この化学結合状態を解析することによって,自由空間中のArには見られないエネルギーの変化(ケミカルシフト)が観測された.これは純粋なSiクラスターが球殻構造を形成し,その中心部にAr原子を内包することで,Ar原子が周囲のSi原子から影響を受けるためと説明できる.以上の結果から,電子銃を利用したSiプラズマ中にArガスを導入しArプラズマを作用させることで,Ar原子内包Siフラーレンを形成できることが明らかとなった. 7.Si-W混合クラスター形成実験を行ったところクラスター内にWの存在が確認された.金属内包Siフラーレン形成に向けて実験を継続して行っている.

1. When a substrate covered with dispersed single-walled carbon nanotubes (SWNTs) is immersed in an alkali-fullerene plasma of Cs^+ -C_<60>^-, both of C_<60> and Cs encapsulated SWNTs (C_<60>@SWNT, Cs@SWNT) are formed as a result of accelerated-ion irradiation in an energy-controlled manner through the plasma sheath. Furthermore, the SWNT encapsulating a junction of Cs atoms on one side and C_<60> molecules on the other [(Cs/I)@SWNT] is observe to be formed in the case of applying bias voltages with polarity change. 2. For the purpose of creating an ideal nano-pn junction, an alkali-halogen plasma such as Cs^+ -I^- is successfully generated using a magnetron discharge method with alkali salts. The substrate bias method leads to the generation of both the I@SWNT and junction encapsulated SWNT, (Cs/I)@SWNT. 3. Electronic transport measurements reveal that C_<60>@SWNTs give rise to a p-type semiconducting property, but that Cs@SWNTs exhibit air stable n-type transport characteristics changing from p-type transport behavior via ambipolar behavior as the Cs-injection quantity inside SWNTs is increased. Moreover, Coulomb oscillations are observed under low temperatures, which is derived from the electronic structure modulated mainly by the encapsulated Cs atoms. 4. In the case of I@SWNTs the threshold gate voltage of FET, which shows the p-type conductivity, is found to shift to a more positive value as the I-injection quantity is increased, indicating the strong enhancement of p-type property. Finally, the electronic transport property of (Cs/I)@SWNT is observed to behave as a diode, suggesting the formation of nano-pn junction. Thus, our evolved carbon nanotubes created by plasma ion irradiation are considered in principle to be provided with hidden potential as an ultra-super nonlinear-electronic microdevice.

1、伝導冷凍型超電導マグネット(最大磁場強度4T,開口44cm,長さ25cm)の内側に直線型真空容器(直径20cm,長さ160cm)を設置し,装置の一方の端で熱陰極型直流放電プラズマ発生源を用いてアルゴンプラズマ流(電子温度1〜2eV,プラズマ密度10^9〜10^<12>cm^<-3>)を生成し,真空容器内に導入した.この時,磁場強度が最大である装置中央にマイクロ波入射用のアンテナを設置し,そこからプラズマ中にマイクロ波信号発振器により発生させたマイクロ波(周波数60及び6GHz,出力150mW)を入射した. 2、昨年度の研究成果から,マイクロ波が磁力線に対して斜め方向に伝搬する,すなわち有限の半径方向(磁力線垂直方向)波数を有することが左旋円偏波から右旋円偏波への偏波方向反転の原因である可能性が示唆されているので,本年度はまずプラズマ直径を変化させることで半径方向波数を変化させ,その偏波方向反転への効果を調べた.その結果,プラズマ直径が細くなるに従って,すなわち半径方向波数が大きくなるに従って偏波方向反転が電子サイクロトロン共鳴点(ECR点)に近い位置で起こることが明らかになった. 3、次に,電子密度,電子温度を変化させで偏波方向反転の特性を調べたどころ,電子密度が高いほど,また電子温度が低いほど偏波方向反転が起こりやすいことが分かった. 4、これまでの結果を考察するために,有限境界および不均一磁場配位の効果を導入したプラズマ中電磁波の分散関係および偏波方向の度合いを理論的に求めたところ,半径方向の境界条件に起因する左旋円偏波と右旋円偏波の分散関係の結合,および同軸状プラズマ円柱の導波管としての効果によって偏波方向反転が引き起こされていることが明らかになった. 5、この理論的に得られた分散関係を実験結果と比較したところ,半径方向波数への依存性なども含め非常に良く一致し,左旋円偏波のECR点での減衰を右旋偏波への偏波方向反転によって説明できることを明らかにした.

The multi-walled carbon nanotubes (MWNTs) are formed by plasma-enhanced chemical vapor deposition directly on the rf electrode under the condition of the strong magnetic field. It is noted that the nanotube structure at B_z=0.03 T is very thick from the analysis by the transmission electron microscopy (TEM), it is confirmed that a few MWNTs combine with each other and become the thick nanotube-like graphitic material. In this case, since the ions are accelerated by the negative sheath voltage (V_<sh>) in front of the rf electrode and impinge on the rf electrode with high energy, the generated MWNTs are considered to be deformed by the bombardment of the high energy ions. When the strong magnetic field (B_z=2 T) is applied perpendicularly to the sheath electric field, the magnetic field prevents the high energy ions from directly impinging on the rf electrode due to the magnetization of ions, even if the large sheath electric field exists. Furthermore, the current of the ions as a carbon source toward the rf electrode remains to be enough large to form the nanotube. Thus, the MWNTs formed at B_z=2 T are found to be well-aligned by the sheath electric field and not to be deformed due to the reduction of the ion bombardment energy toward the rf electrode. This result can be explained by the reduction of the ion bombardment energy, which is caused by the magnetization of the ions for B_z=2 T. It is found that the controls of the sheath voltage and the ion bombardment energy by the magnetic field introduction have crucial effects on the nanotube growth.

空間に浮かせたまま3次元的に結晶成長をさせることができれば、結晶は基板などに邪魔されることなく自由に成長し、純粋な結晶を作る上で極めて有用と考えられる。本研究では、低電子温度化したメタン水素プラズマ空間内に、負に帯電したダイヤモンド微粒子を浮上させ、その表面に成膜することによりダイヤモンド微粒子の空間的成長過程を明らかにする。真空容器内にダイヤモンド微粒子浮上装置を組み立てて実験を行なった。実験装置は円筒状であり、上下の部分に分割する。下部はプラズマ源であり、13.56MHzの平行平板高周波放電を行ってプラズマを生成する。上部との境界には、竜子温度制御用のグリッドを設置し、このグリッドの位置を調整することによって上部に生成されるプラズマの電子温度を制御する。グリッドによって低温化された上部のプラズマ領域にダイヤモンド微粒子を注入し、プラズマ中に浮上させた。2時間、4時間、8時間経過後に浮上微粒子を回収してラマン分光、及びSEMで表面を観察した。2時間のダイヤモンド微粒子の表面に数10nm程度の結晶核が多数成長してることが分かった。4時間、8時間とプロセス時間が増すにつれて、結晶核の密度及び大きさが増加することが分かった。この希晶核の成分は炭素であることが分析の結果分かった。結晶核の形状ば正四角錘のようであり、(111)面をもつダイヤモンド結晶核の発生と思われる。このとき、ダイヤモンドの外部加熱は無く、200度以下の低温でダイヤモンドが成長したものと考えられる。この条件の元で、ニッケルの基板にも同様な結晶核が観察された。本研究で用いたダイヤモンド浮上成長法は、低電子温度プラズマ中でのみ有効であることが分かった。

今年度は、メタン(CH_4)/水素(H_2)混合ガスによる非平衡反応性高周波(RF)グロー放電の、弱磁化プラズマ内に設置した触媒金属を兼ねたRF電極に外部から直流電圧を印加して電位(V_<RFE>)を制御した場合の、カーボンナノチューブ(CNTs)成長状態とフラーレン形成量の詳細を調べた結果、以下のことが判明した。 (1)RF電極に生じる自己バイアス電圧(-300V)よりもやや高いV_<RFE>=-210Vの場合、CNTsは殆ど存在せずに多面体状グラファイトが大半を占めていた。しかし、V_<RFE>を負に深くすると、CNTsが頻繁に観察され、V_<RFE>=-400Vでは、単独に成長した直径70nm、長さ10μmの細長い多層CNTsの形成が確証された。更に、フラーレンを内包したCNTsの形成を示唆する結果が得られている。 (2)現行の質量分析の他に、可視/紫外吸収分光器による水冷式RF電極上に堆積した煤の分析を行った。その結果、フラーレンC_<60>とC_<70>の吸収が観測され、それらの強度はRF投入電力の増加に比例して増えることが判明している。ゆえに、各種パラメーターの最適条件を見出すことにより、フラーレンの大量合成のみならず、ナノチューブ形成機構の解明にも大きく寄与すると考えている。 (3)我々の実験におけるガス混合比(H_2/CH_4=1/9)は、従来の熱又はプラズマCVD法の場合と比べると逆転しているため、従来の基板加熱膜成長法とは全く異なるC_<60>因子のより高次構造の炭素クラスター形成機構が存在することを示唆する結果が得られた。以上の結果を総合すると、CNTsの単独形成・成長とフラーレン形成には、RF電極表面に平行な弱磁場を印加するマグネトロン放電方式による特異な放電形態に起因した、電極へのイオン衝撃による多面体状グラファイトの分解・合成の促進と、それに伴なうRF電極表面温度変化との相乗効果が重要であるという結論に達した。

(2)昨年度の実験結果から,垂直方向に磁場を印加し,中央の透明電極に電位を印加することで,微粒子雲が水平面上で剛体回転を始め,その回転方向,速度が透明電極電位に依存していることが分かっている. (3)本年度は先ず,この微粒子雲回転運動の磁場強度依存性を観測した.その結果,磁場の増大とともに回転速度は増加していくが約1テスラで最大になり,その後は磁場の増大とともに回転速度は減少し次第に飽和していくことが,テスラ級の強磁場を印加することによって初めて明らかになった. (4)次に,アルゴンガス圧力を変化させて(3)と同様に磁場強度依存性を観測したところ,ガス圧力の増加とともに微粒子雲回転速度が最大になる磁場強度が正にシフトしていくことが分かった.これらの結果は,微粒子雲の回転がアルゴンイオンとの衝突により駆動され,そのアルゴンイオンの衝突時の運動量がイオンサイクロトロン周波数とイオン-中性ガス衝突周波数との関係で決まるためと考えられる.微粒子雲回転速度が最大になる時,これらの周波数がほぼ一致していることも明らかになった. (5)微粒子雲に衝突するイオンの軌道をモデル化し,微粒子雲回転速度の数値計算を行ったところ,ほぼ実験結果と一致し,テスラ級強磁場中での複雑な微粒子雲の回転機構を説明することができた.

The endohedral metallofullerene K@C_<60> was successfully formed by the energy and flux control of K^+ and C^-_<60> ions flowing into substrates in experiments of the thin-film formation with a potassiumfullerene (K^+_-C^-_<60>) plasma. Since the K@C_<60> production ratio to C_<60> was at most 30% and usually 5〜10% or less, however, it was difficult to clarify the relation between the plasma effect and encapsulation mecharuism. From the abovementioned viewpoint, the experiments were carried out by a sodiumfullerene (Na^+_-C^-_<60>) plasma, where the diameter of Na^+ is srmaller than that of K^+. The following results were obtained. According to the mass analysis of thin films formed on the substrates, the large massspectrum peak (Na(@)C_<60>) corresponding to the Naendohedral fullereoe is observed. The average intensity ratio of Na(@)C_<60> to C_<60> is turned out to be 30〜50%. Moreover, the Na(@)C_<60> production ratio to C_<60> in a narrow region of the substrate attains to 200% or more. When the substrate bias is chansed, the average spectrumpeak intensity of Na(@)C_<60> is found to give the maximum value at a specific voltage. The composition and structure of the thin film are directly investigated by the highresolution electron microscope (HREM) observation. A lot of C_<60> molecules with dark shadows around the centers are observed over the image of the thin film in the narrow region of the substrate. The round material imaged by the HREM is considered to be C_<60> encapsulating Na inside the cage, because the Na^+ diameter almost corresponds to the dark shadow diameter. It can be said that a large amount of production of the Na-C_<60> compound materials containing Na@C_<60> facilitates the constituent analysis and structure observation for the purpose of clarifying their physical and chemical properties. This work is also important in the sence of establishing the method of forming fullerenebased thin films with new functions.

1) A Gifford-McMahon (GM) cryocooled superconducting magnet with a 40-cm-diam and 40-cm-length magnet bore produces the high magnetic field of 4T (max) at the axis center of the bore. A cylindrical vacuum chamber is inserted into the magnet bore and an argon (Ar) plasma is generated by a dc discharge between a spiral-shaped hot tungsten cathode and a tungsten mesh anode located in the upstream region of the chamber in a low pressure argon gas. The oven temperature for sublimation of the fullerenes (C_<60>, C_<70>) is changed to cover the temperature range of 350-400℃. The high energy electrons of the Ar plasma are injected into this oven and ionize the neutral fullerene vapor within the oven. 2) At the first step, an omegatron mass analyzer is used for a fullerene-ion mass separation, the principle of which is based on the ion cyclotron resonance, in order to clarify that the electromagnetic isolation technique is able to be applied to the fullerene whose mass number is very large. As a result, it is found that the frequency spectra yield two peaks, the frequencies of which are in good agreement with the predicted ion-cyclotron frequencies of C_<60> and C_<70>, respectively, when high magnetic field (B=1〜2.4 T) is applied. Furthermore, it is found that the mass resolution M/ΔM increases with an increase in B, reaching M/ΔM=30 at B=2 T. 3) Next, we develop the fullerene-ion mass-separation device using a helical antenna, which can separate and purify the fullerenes at a high rate. This helical antenna can inject a large RF power into the high-density fullerene-plasma. It is also demonstrated that the fullerenes can be separated by this device and the ion current collected at the C_<60> peak increases with an increase in the RF power, which proves the possibility of isolating new-function fullerenes.

1) A modified plasma-synthesis method is developed in order to actively control an ion flow energy in a magnetic field, where ion and electron emitters of the same diameter are oppositely set at cylindrical machine ends and the ion emitter is concentrically segmented into three sections. The field-aligned ion flows with radially-different energies are generated in a radially-uniform plasma potential when each section of the segmented ion emitter is individually biased at a positive value above the plasma potential. 2) This ion drift difference between adjacent layers, or a radial jump of the field-aligned ion flow velocity is found to give rise to several types of low-frequency instabilities. 3) One is observed around the radial center where the density profile is almost uniform. This instability is localized around the region of the flow-velocity jump, and the fluctuation amplitude becomes large when the flow-velocity difference between the two electrodes increases. Thus, this instability is considered to be related to the Kelvin-Helmholtz instability to some extent. 4) For the larger flow-velocity gradient, another is observed in the region where the density gradient is relatively large. It is found that the frequency of this instability is the sum of the electron-diamagnetic drift frequency and the frequency which is determined by the ion flow-velocity. Thus, this instability appears to be related to the electron-drift and ion-acoustic coupled wave, which has not been argued in the conventional plasma.
