異なる幾つかの、グリシン濃度, pH、および充填率(=グリシン溶液の質量/MCM-41の乾燥質量))をパラメーターとして、メソポーラスシリカ(MCM-41)に閉じ込められたグリシン水溶液の示差走査熱量測定、X線回折および準弾性中性子散乱(QENS)を305-180Kの温度範囲で実施して、グリシン水溶液の熱的挙動, 構造、および動的特性に対する閉じ込め効果を検討した。

Differential scanning calorimetry, X-ray diffraction, and quasi-elastic neutron scattering (QENS) measurements of aqueous glycine solutions confined in mesoporous silica (MCM-41) were performed at different glycine concentrations, pH, and loading ratio (= mass of glycine solution / mass of dry MCM-41) in the temperature range from 305 to 180 K to discuss the confinement effect on the thermal behavior, the structure, and the dynamic properties of the solutions.
