    Research paper (scientific journal)   Multiple Authorship

    溶融法で作製したガラスはプロトン(=OH基)濃度が低く、ガラスのプロトン伝導性は一般的に非常に低いです。以前に我々は燃料電池発電雰囲気に曝されることでガラスのプロトン伝導性が向上することを見出しています。燃料電池発電雰囲気を模擬した独自開発のin-situ赤外線分光装置を用いて、発電下でガラスのプロトン濃度が上昇するプロトン注入効果を初めて定量的に明らかにしました。論文では放射光X線による構造解析と合わせてプロトン注入を議論しています。

    室温付近でも高いAg+イオン伝導性を示すAgI-Ag2O-B2O3ガラスを先鋭化して電界印加することで、室温かつ大気圧雰囲気においてもAg+イオン放出を確認しました。Ag+イオン放出寿命を電気化学水晶振動子微量天秤による電流値と振動数変化から議論しています。またAg+イオン照射後のガラス基板にはより多数のHeLa細胞が付着することを明らかにしました。兵庫県立大学との共同研究成果です。

    Research paper (scientific journal)   Multiple Authorship

    SiO2(シリカ)はSiが4つの酸素で囲まれていますが、4つのうち一つをフェニル基に置き換えたものがフェニルシルセスキオキサン(PSQ)と呼ばれます。このPSQ粒子はゾル-ゲル法によって合成でき、粒子をガラス転移温度以上で加熱プレスすることで透明なバルク体に転移し、また絶縁性も比較的高いです。粒子→バルク転移時の変形挙動をin-situ解析したところ、粒子間にボイドが存在する場合は粘弾性挙動を示すのに対して、ボイドフリーのものは弾性変形すること、またボイドフリーの方がより高い絶縁耐圧を示すことを実験的に明らかにしました。
