Abstract The optical transparency of silica glass significantly improves when subjected to compression at its melting temperature. Using a rare hydrostatic iso-pressure apparatus capable of reaching 0.98 GPa at 1800 °C with Ar gas as the pressure medium, we obtained centimeter-sized glass samples, allowing us to measure various properties. Both the density and refractive index increased with pressure, while the refractive index dispersion decreased monotonically. However, Rayleigh scattering intensity, and small ring structures show a minimum around 0.8 GPa. High-energy X-ray scattering analysis indicates that the short-range structure, around 4 Å, governs the monotonic trends in the averaged physical properties, such as density and refractive index. In contrast, non-monotonic changes are observed with the disappearance of intermediate-range order at around 8 Å. This simplification of structural ordering is crucial for achieving extreme transparency in silica glass. The effect of suppression of the 8 Å order is well explained by the predicted topological pruning phenomenon, where large voids and small unstable ring structures vanish, leading to the minimal light scattering under high pressure. Our experimental findings also reveal that the optimal pressure for achieving this transparency is much lower than previously predicted, which makes the process more feasible for mass-production applications.

Abstract The corrosion behavior of sodium silicate glass in water may be understood by clarifying the fundamental processes of interface reactions. We investigated the reaction mechanism of the glass surfaces in contact with water for just an immediate dipping up to 1 h later, using x‐ray photoelectron spectroscopy. Silanol formation due to ion exchange of sodium with hydrogen from water was observed from 0 to 30 s, similar to previously reported molecular dynamics simulations. However, the amount of silanol groups decreased after the formation reaction owing to the dehydration of excess silanol groups generated by the initial reactions, thereby promoting the re‐formation of siloxane networks at the glass surface. The generated siloxane network was relatively stable for 30 min owing to their rather rigid network. The silanol group concentration increased gradually at the surface after 30 min, owing to a deficiency of dissolved sodium ions. Thereafter, the sodium ions attracted to the negatively charged glass surface gradually left the surface, resulting in an increase of silanol groups when the glass–water reaction proceeded. These observations of the glass–water reaction over a short period provide insight for improving the durability of sodium silicate glass products and developing efficient polishing and cleaning procedures for glass fabrication.

Abstract Intercalation into 1D transition metal trichalcogenides (TMTs) in which fibers are bonded by a weak van der Waals force can be expected to create various intercalation compounds and develop unique physical properties according to the combination of the host materials and guest ions. However, structural changes via intercalation into 1D TMTs are not as simple as those in 2D transition metal dichalcogenides (TMDs) and are still not understood comprehensively. ZrTe₃: a typical compound with a 1D trigonal prismatic structure, belongs to TMTs. Herein, through the Ag introduction to ZrTe₃ via solid‐state intercalation, a novel crystal phase with a 1D octahedral structure and a quasi‐amorphous (QA) phase during the structural transition are discovered; the QA phase is a novel state of matter in which long‐range order is lost while retaining 1D order. Based on the Ag concentration, the transport properties are flexibly modulated from superconductivity to semiconductivity. Density functional theory calculations indicate the attraction between Ag ions and the pair diffusion due to their attraction. Furthermore, judging the attraction or repulsion between guest ions predicts whether to induce a QA phase or simple lattice expansion like the intercalation into 2D TMDs.

<title>Abstract</title>The ion-exchange and associated interfacial reaction mechanisms of silicate glasses are critical in elucidating their aqueous corrosion behaviors, surface modification and property changes, hence have potential impact on both science and technology. This work reports findings of the atomic and nanoscale details of the glass–water interfacial reactions revealed by applying reactive force field (ReaxFF) based molecular dynamics (MD) simulations, from which the key mechanisms of the ion exchange, as well as the kinetics of associated interfacial reactions, are elucidated. It was found that the Na⁺ and H⁺ ion exchange can happen between two oxygen ions on a single silicon oxygen tetrahedron or adjacent tetrahedra. In addition, the clustered reaction of two non-bridging oxygens mediated by an adjacent water molecule was also identified. The latter reaction might be the main mechanism of water transport after initial surface reactions that consume the non-bridging oxygen species on the surface. Water molecules thus can play two roles: as an intermediate during the proton transfer processes and as a terminator of the clustered reactions. Statistical analyses were performed to obtain reaction kinetics and the results show that silanol formation is a more favored process than the silanol re-formation within the first 3 ns of interfacial reactions. The results obtained thus shed lights on the complex ion-exchange mechanisms during glass hydration and enable more detailed understanding of the corrosion and glass–water interactions of silicate glasses.

<title>Abstract</title> Silica glass is the most indispensable material in optical communication applications due to its superior optical properties. The transmission loss of silica glass has been reduced over the past 30 years by continuous efforts toward decreasing density fluctuations by lowering of fictive temperature, e.g., through improvements in processing or doping. A recent study has shown that shrinkage of structural voids by hot compression is a promising way to further decrease the loss. However, an atomic understanding of the pressure effect is still lacking. Here, using molecular simulations, we connect the void shrinkage to topological pruning of silica network. Two physical models predict that the Rayleigh scattering loss of pressure-quenched silica glass can be reduced by >50% when the glass is quenched at an appropriate pressure (4 GPa in our simulation). Our studies are consistent with available experimental results and demonstrate topologically optimized structure can give desirable properties for optical applications of silica as well as other glasses with similar network structure.

More details Close

Positron annihilation lifetime spectroscopy (PALS) is a powerful technique in the characterization of void sizes in various kinds of materials. In this work, silica glasses with different fictive temperatures (Tf) were investigated using PALS. Although the density of silica glass is well known as to increase – so that the space is supposed to decrease - with higher Tf, voids were observed to expand. Considering the results of molecular dynamics (MD) simulations, a picture of structure and voids and its temperature dependence in silica glass will be proposed.

「超秩序構造」を理解することにより、ナノスケールで高度に構造を制御し、新規高機能性材料の創出が期待される。現在、構造・物性・機能の制御が完全に達成できていない材料群として、ゼオライト、蓄電池材料、ガラス、半導体材料に着目し、超秩序材料の設計による高機能材料の開発とその社会実装へ向けたスケールアップ検討を目的としている。固体と液体が存在する系で合成されるゼオライトにおいて、多くは固液を分離したうえで固体成分の構造変化等をex situ条件で分析してきた。合成条件下での結晶化の挙動をin situ測定することにより、ex situ測定だけでは得られなかった情報を得ることができると考えられる。触媒などとして用いられるCHA型ゼオライトを対象とし、in situ HEXTS測定を行った。合成装置の改良によってゼオライトのin situ測定の適用範囲を広げ、実際に初めて合成途中にリング構造が変化する様の観察に成功した。特にアルミノシリケート非晶質の重縮合に伴う4員環の増加がCHAゼオライトの核発生前に進行していることを明らかにした。リチウムイオン電池の負極材料として、超高速充放電が可能なTi-Nb-O系材料に着目し、TiNb2O7にInを置換した試料とTi:Nb比が異なる試料を合成して充放電試験を行った。その結果、In置換により放電容量が増加することが明らかになった。希土類シリケート二元系ガラスの合成に成功し、機械特性評価や構造解析を行った。また、リン酸塩ガラスに微量添加したクロムが、化学的耐久性を劇的に向上させること、またそれが強い組成依存性を示すことを見出した。HIPを用いて1800℃、高圧下処理した高純度シリカガラスを得た。これらのガラスのレイリー散乱光係数を測定したところ、0.2 GPaの結果は既報データと整合性が良く、圧力が高いほど散乱が小さくなった。

[本研究の目的]ガラスは通常その原子構造がランダムなため、構造制御による特性の制御や向上は難しい。しかし、代表者は近年高圧高温処理によりシリカガラスの構造秩序性が変化し、光学特性が向上することを明らかにした。特に圧力で空隙構造（原子の存在しない部分）の収縮が起こりやすいため、本研究では、格子定数が空隙サイズに近い結晶基板に接触成長させることで、特殊なトポロジーを有するガラスを作ることに挑戦している。つまり、本研究は、従来超高圧超高温を使わなければできないガラスのトポロジー制御を、結晶基板表面特有の活性な境界条件を利用して実現する、革新的ガラス（薄膜）合成法を構築することを目的としている。 [本研究の実施計画]本研究では、新しいコンセプトによる結晶基板上へのガラス薄膜の作製と構造評価を行い、ガラス構造の制御の可能性、特性向上の可能性を探ることを主な実施内容としている。このため、実施項目として順をおって下記の項目①～④を進めている。① 複数種類の結晶基板を使い、また、表面の活性状態を複数種類の製膜装置を用いて変えて、ガラス薄膜を制作する。② 作製したガラス薄膜の特徴を捉える評価方法を調べ、確立する。③ 作製したガラス薄膜の特性を調査し、特性の向上の有無を調べる。 ④ 2次元ガラスの構造や特性について、コンピュータシミュレーションを用いてモデル化を可能にする。これらを行うことにより、革新的ガラス薄膜合成法及び評価方法を構築することができると考えており、更に、ガラス構造や特性の次元による変化について議論できるようになれば新しい分野を築くことになり、非常に意義が大きいと考えている。令和３年度の実績として、①、②を進めており、③、④に関しては調査や、研究協力者との議論を進めている。

本研究は、北大グループと東北大・産総研グループが連携して、リン酸塩ガラスのプロトン移動度の支配因子を学術的に明らかにすることを目的としている。北大グループは、Na2O-La2O3-GeO2-P2O5系ガラスにおいて、LaをGeに置換することでプロトン伝導度が上昇する現象を見いだしていたが、その原因は未解明であった。そこで、東北大・産総研グループ、およびNIMSと連携して、ガラス構造とプロトン伝導度の相関の解明に取り組みんだ。SPringの高エネルギーX線回折測定によってGeが6配位であることが明らかとなり、XPS,NMR測定より、P-O-Ge結合の形成がプロトンの移動度の向上に重要な役割を担っていると推察された。本研究は、ガラスにおけるカチオン移動現象に関する重要な知見であることから、体系的に整理した上で論文投稿する予定である。また、北大グループは、Na2O-SiO2-P2O5系ガラスにおいて、Naの90%以上をプロトンに置換することでプロトン伝導が発現することを見出した。この組成系は、現在までに報告されている中で最も単純な3成分系である。最近、高エネルギーX線回折測定によりSiが6配位であり、プロトン伝導の活性化エネルギーが、これまで検討してきたガラス系の中で最も高い1.2eV以上であることが分かった。このガラス系は、本研究課題の目標である『ガラスにおけるカチオン移動現象の科学』を深める上で重要であることから、東北大・産総研グループと連携して、プロトン伝導とガラス構造との相関について詳しく検討する予定である。
