    Abstract In this study, we investigated the effects of the sheet texture of the Mo underlayer on the c-axis texture of the high-rate-sputtered Nd2Fe14B phase. The magnetic properties revealed that the squareness of the Nd–Fe–B magnetic layer did not depend on the sheet texture of the Mo underlayer but on the substrate temperature: large squareness was obtained when the magnetic layer was sputtered at high substrate temperature above 500 °C. In-plane X-ray diffraction measurements indicated that the intensity of diffraction from the Nd2Fe14B (410) plane did not depend on the sheet texture of the Mo underlayer but on the substrate temperature: high intensity was obtained when the magnetic layer was sputtered at above 500 °C, which was consistent with magnetic properties. These results support that the c-axis texture of the high-rate-sputtered magnetic layer was driven by the c plane with the lowest surface energy among the crystal planes in the Nd2Fe14B phase.

    Microwave irradiation accelerated hydrogen production by catalytic pyrolysis of crystalline cellulose and bamboo via Ni-SiO2-Al2O3. The Debye-Waller factor measured by microwave in situ XAFS suggested that the reaction was accelerated due to the localized high temperature of Ni nanoparticles formed by microwave irradiation. We demonstrated that synergy of the microwave-enhanced pyrolysis of biomass and localized high temperature of Ni nanoparticles accelerate the catalytic pyrolysis of lignocellulose to produce hydrogen.

    Silver Nanowires, Silver Carboxylates, Transparent Conductive Films, Low-Dimension MaterialsAbstract: Silver nanowires transparent conductive films are expected as a material to replace indium tin oxidefilms. Silver nanowires are mainly synthesized by the polyol method, which used protective agents to achievean anisotropic crystal growth. However, protective agents decrease conductivity of the films because theycover the surface of nanowires. In this study, we have conveniently synthesized needle-shaped silvercarboxylates by ultrasound irradiation, and then obtained silver nanowires transparent conductive films byspray coating them on substrates and exposing them to gas-phase hydrazine.<br>Silver carboxylates were synthesized by ultrasound irradiation to mixture that contains silver(I) oxide, aceticacid, propionic acid, and ethanol. These carboxylates were put onto a glass substrate, and then reduced byexposure to hydrazine gas (vaporized hydrazine monohydrate). The obtained samples were characterized byFE-SEM, XRD, TG-DTA, four-probe method, and UV-Vis.<br>Silver oxide completely reacted and silver carboxylates were produced after 1 h of ultrasound irradiation(22.32-44.13 kHz, 100 W). Raw materials were most homogeneity dispersed and consumed at 44.13 kHz. Thestudy on coating conditions of the precursor, in case of short height of the spray, produced transparentconductive films showed low transmittance and very low resistance. And high transmittance and lowresistance were achieved by adjusting the coating time and spray height.

    Copper nanoparticles(CuNPs) are expected to be novel wiring materials because of low sintering temperature and low-priced ingredients. CuNPs are usable as a ink for wiring. This ink printed on a circuit board conducts electricity after proper heat treatment. However, CuNPs oxidize easily in the air. To prevent oxidation of CuNPs, additional costly process are needed such as atmosphere exchanging into an inert atmosphere. On the other hand, organic compounds have been used as protectors for CuNPs, but these non-metallic coverings often reduce conductivity of CuNPs. Hence, Cu-Ag nanocomposites(Cu-Ag NC) have been considered as an alternative method to prevent oxidation. In this study, Cu-Ag NC were easily synthesized under high concentration condition by using ultrasonic irradiation. Ultrasonic irradiation was easily process to combine metal nanoparticles with other materials. However, CuNPs and silver nanoparticles repel each other in a solvent because of positively charged particles. To change charge of CuNPs, oxidization of CuNPs is available. CuNPs were purposely oxidized, then synthesis of Cu-Ag NC became easily. Cu-Ag NC were reduced on a glass substlate, and electric resistivity of the sample were decreased from 2.267 Ωcm to 1.690 × 10^<-4> Ωcm.

    Hard chromium plating has been used to improve hardness, resistance to corrosion, friction and heat in various fields. However, alternative technology of hard chromium plating is desired because of toxicity of raw materials. Thus, we developed a novel method to fabricate a hard film by using Cr nanoparticles. Although this method is easy and environmentally friendly, Cr nanoparticles are expensive at present because Cr nanoparticles are synthesized by vapor deposition. In this study, we tried to synthesize Cr nanoparticles in solvent by ultrasonic decomposition of Cr(CO)_6. Cr(CO)_6 was fully decomposed by ultrasonic irradiation in decanol at 50 ℃ for 30 min. The product had a low crystallinity and particles sizes were about 5 nm. In TG-DTA, products exhibited weight loss (33 %) around 1000 ℃ in Ar by decomposition of organics. In XRD, Cr and Cr_2O_3 were observed after heating at 1000 ℃ in Ar. It is considered that surfaces of Cr nanoparticles were formed oxide shells of Cr_2O_3 as passive layers. When the atmosphere was changed from Ar to air in 1000 ℃, products exhibited weight gain due to oxidation of Cr.

    Recently, graphene has attracted tremendous research interests due to its unique mechanical, electrical and thermal properties caused by a two-dimensional, single-atom-thick structure of sp2-bonded carbon atoms. In the past few years, several methods, such as chemical vapor deposition and exfoliation of graphite powder in high boiling point solvents, have been used to prepare graphene sheets. It is known that chemical reactions, stirring, dispersion and exfoliation are promoted by ultrasound-cavitation. In this study, the production of unfunctionalized and nonoxidized graphene by exfoliation of graphite flakes in solvents is synthesized and characterized. We used 2-propanol (IPA) and acetic acid as low boiling point solvents. A stable homogeneous dispersion of graphene was obtained by solid-liquid sonochemical reactions using IPA and acetic acid mixed solvents. STEM images and electron diffraction pattern shows the presence of mono- and few-layer graphenes. As a result, graphene could be synthesized in low boiling point solvent. The solvent, IPA, was simply and quickly removed by air-drying, and dose not leave any residue of the solvent in the graphene sheets.

    Silver nanowire transparent conducting films (TCFs) are expected to be alternative materials for indium tin oxide TCFs. Silver nanowires are typically synthesized by polyol method. It requires protective agents to achieve an anisotropic crystal growth, however, protective agents cover the top surface of nanowires, and hence decrease conductivity of films. In this study, we have conveniently synthesized needle-shaped silver carboxylates by ultrasound irradiation, and then obtained silver nanowires transparent conductive films by spraying them on substrate and exposing them to gas-phase hydrazine. Silver carboxylates were synthesized by ultrasound irradiation to mixture that contains silver(I) oxide, acetic acid, propionic acid, and ethanol. These carboxylates were put onto glass or polycarbonate (PC) substrate, and then exposed to hydrazine gas (vaporized hydrazine monohydrate) to reduce. The obtained samples were characterized by FE-SEM, XRD, TG-DTA, four-point probe and UV-Vis. Silver oxide was completely reacted and silver carboxylates were produced after 1 h of ultrasound irradiation at 10-40 ℃, that is relatively low temperature compared to conventional method. Decreasing reaction temperature, it was confirmed that diameters of the precursor were reduced by 25%. Diameter and aspect ratio of the precursor were decreased for longer reaction time because of sonofragmentation. To reduce diameter with keeping aspect ratio, lower temperature can be effective. Transparent conductive films, which were produced by spraying and reducing precursor, show high transmittance and low resistance at 80 ℃ of reduction temperature. However resistivity have been drastically increased for higher temperature because their specific one-dimensional shapes have been completely lost.

    Printed electronics is one of the inexpensive fabrication for electronic circuits and it is expected to be an alternative to conventional method such as photolithography. Commercial conductive ink for printed electronics often uses Ag nanoparticles(AgNPs), but AgNPs are expensive. Accordingly, Cu nanoparticles(CuNPs) are expected to replace for AgNPs, because Copper is much cheaper than silver and has high conductivity. However, Copper oxidises easily in the atmosphere. To prevent oxidation of Cu, organic compounds have been used as coverings for CuNPs, but these non-metallic coverings often reduce conductivity of CuNPs. Hence, Cu-Ag nanocomposites(Cu-Ag NC) have been considered as an alternative method to prevent Cu oxidation. In this study, Cu-Ag NC were easily synthesized under high concentration condition with microwaves and ultrasonication. Microwave heating is effective method for synthesis of nanoparticles because of its effect to heat polar solvents quickly and uniformly. Ultrasonication is easily process to synthesize composites of nanoparticles and other materials. The sample synthesized showed the form that AgNPs attached to the surface of CuNPs in its SEM images. Thermogravimetry measurement suggested that the sample has high oxidation resistance against CuNPs.

It requires protective agents in order to achieve an anisotropic crystal growth, however, protective agents cover the surface of nanowires, and hence decrease conductivity of electrodes. In this study, we have synthesized needle-shaped silver carboxylates by ultrasound irradiation without any protective agent, and then obtained silver nanowires by exposing them to hydrazine gas. Silver carboxylates were synthesized by ultrasound irradiation to mixture that contains silver(I) oxide, carboxylic acids(2-6C), and ethanol. These carboxylates were put onto glass substrate, and then exposed to hydrazine gas (vaporized hydrazine monohydrate) to reduce. The obtained samples were characterized by FE-SEM, XRD, TG-DTA, and UV-Vis. Long needle-shaped silver carboxylates were observed after ultrasound irradiation. In contrast to stirrer, we obtained well-dispersed silver carboxylates by ultrasound irradiation. In addition, it was confirmed that the reaction rate is greater than that of stirrer. These results are due to effects of ultrasound, such as strong dispersive power, erosion, and high temperature-pressure reaction field. Silver nanowire TCF were prepared by reducing silver carboxylates. This film indicated low resistivity and high transparency.

    Ecology and Economy synthesis is important in the future. There are some elements to achieve this synthesis. One is a production device. A cheap device is hoped for in not an expensive, special device but the general purpose. The second is a raw material. When synthesizing, neither waste nor the air pollutant are not generated, and it is safe and nontoxic raw material is preferable. The third is a synthetic temperature. Low temperature synthesis as much as possible is suitable from the viewpoint of energy conservation. Sustainable processing for Platinum nanoparticles were developed by novel ultrasonic and microwave liquid-solid reaction. We used Platinum oxide as metallic source and water based solvent in this system. This system can be synthesized 2-3nm Platinum nanoparticle in short time and non-waste, so low-pricing of Platinum nanoparticle is realizable. By using water-ethanol mixed solvent, it can obtain dispersant-free Platinum nanoparticles suitable for catalyst, etc. In this study, fabricated conditions were examined in detail, reaction mechanisms and morphology of products were investigated.

In this work, Graphite Oxide (GO) and Ag/graphene nanocomposites were synthesized by solid-liquid sonochemical reactions easily and briefly. GO was synthesized by means of Hummers method using sonication or stirring. From XRD patterns and FT-IR spectra, the oxidation of graphite was promoted by chemical and physical effects of ultrasound. Ag/graphene nanocomposites were synthesized from GO and silver oxide by sonication. UV-vis spectra showed the peaks of graphene oxide and Ag nanoparticle plasmon resonance absorption. EDX images and electron diffraction patterns confirmed Ag nanoparticles were decorated on graphenesheets by ultrasound. Using sonication, GO and Ag/graphene nanocomposites could be synthesized easily in short time.

    TiNコーティングは, 硬度, 耐摩耗性, 耐食性等に優れ, 審美的な金色を呈すること, さらに抗菌性や生体親和性も期待されるため, 歯科インプラントアバットメント表面の機能向上にも適していると考えられる. しかし, 従来の成膜法(PVD法, CVD法等)では, アバットメントのような複雑な立体構造体への応用は難しく, 成膜プロセス上の煩雑さ, 安全面やコスト面においても様々な問題が残されている. マイクロ波ドライプロセスTiNコーティング法は,圧力や雰囲気置換を行わない大気中においてTiN形成が可能という独自性を持ち, 安価で簡便なプロセスであり, アバットメントへの応用に適している. 本研究は, 硬度, 耐摩耗性, 耐食性, 審美性, 細胞動態および軟組織封鎖性という観点から, マイクロ波ドライプロセスTiNコーティング法のアバットメント表面における最適成膜条件の探索を行い, トランスレーショナルリサーチの展開へ向けての基盤を形成する. 今年度は, 市販のアバットメントへの応用を想定した試料の作製・材料学的評価を進めた. Ti6Al4円盤(直径5mm, 厚さ1mm)にマイクロ波ドライプロセスによるTiNコーティングを施した試料を作製した. 反応時間は10分とし, 800℃, 850℃, 900℃, 950℃, 1000℃の反応温度でコーティングを施した. SEM像では全ての反応温度において波模様の微細構造を認めた. XRD分析の結果からは, 反応温度が高いほど窒化が進行しており, 950℃, 1000℃でTiNを認めた. この結果, 市販のアバットメントへの成膜条件として, 上記の反応温度が妥当であることが確認された.

    We aimed to establish the theory of microwave-accelerated solid-solid and solid-gas reactions. We established a methodology to observe the local thermal non-equilibrium on the surface or in the bulk of solids under microwaves. We succeeded in developing in situ measurement instruments for direct observation of local temperature and structure of materials during microwave irradiation using XAFS, Raman, light emission spectroscopy coupled with a high resolution thermography. We demonstrated that the formation of a local high-temperature is the key mechanism that microwaves accelerate chemical reactions. Furthermore, we clearly showed that this method could be used to control solid catalytic reactions and synthesis of new solid materials.

    In this study, a new metastable white phosphor was prepared by using the quenching effect of containerless processing. Novel gas-floating containerless processing system have been developed. The device can control the cooling rate and synthesized a new metastable phase in the La-W-O system, which shows white fluorescence near the eutectic composition of about 80 mol% WO3 in the La2O3-WO3 phase diagram. The metastable phase was estimated to be slightly richer in La than the eutectic composition from the compositional study experiments. The sample containing this metastable phase showed white fluorescence with a high red component than that of CaWO4.

    希土類フリー磁石材料の開発は、我が国のエネルギー戦略における最重要テーマの一つである。本研究はこれまでの当該分野の研究成果を踏まえ、軽元素(H,C,O,N)を利用した新しい物質合成法の反応メカニズムを解明するとともに、軽元素がFe合金の磁性に与える影響を理論計算によって解析し、希土類フリー磁石材料の材料設計指針を構築することを目標としている。初年度前半(4月~6月)は、1.酸化物経由によるナノ組織の形成過程の解析および2.磁気異方性、交換相互作用の第一原理計算について予備検討を開始した。1.においてはこれまでFeの酸化物のみを対象としていたが、今回Fe合金まで範囲を広げて検討した。最初にFe-M合金(M=Si、Mn、Ni)において空気を流した場合の酸化開始温度を求めた。M元素を添加することによって酸化開始温度は高くなり、約800 ℃以上となった。Feの場合は約400 ℃であるから大幅に高くなる。元素によって異なるものの、800~1000 ℃の間で(Fe,M)2O3あるいは(Fe,M)3O4の酸化物を得ることができた。次にこれらの還元条件を検討した。還元は水素ガスを流しながら行った。これも元素によって異なるものの役500 ℃以上でFeに還元されることがわかった。結晶子の大きさも還元温度が高くなるにしたがい増大する傾向にあるが、無添加の場合と比べて結晶子の大きさは小さく、M元素に粒成長抑制の効果があることがわかった。2.においては、理論計算の対象とする物質のスクリーニングを開始した。基盤研究Sに採択されたため本研究は廃止になったが、当該内容を継続して研究を進める。

    In order to prove a hypothesis that driving forces of chemical reaction under microwave irradiation is not only thermal energy derived from microwave irradiation but also chemical energy due to given from microwave energy before its thermallization, emission spectroscopy was conducted to measure a transition process that microwave energy directly transits to light energy.An emission spectroscopic apparatus, which can apply to measuement during microwave irradiation, was developped and light emission spectroscopy was tried under microwave irradiation. Reduced titanium oxide (TiO2-x) was selected as a material. As a result, high intensity nonthermal luminescence superimposed on thermal radiation was observed, suggesting an existence of energy path different from thermal relaxation.
