| Research Abstract |
Differential scanning calorimetry measurements of water and NaCl aqueous solution, confined within mesoporous silica of pore diameter 1.4-45.7 nm, were performed. The freezing temperature of water within the pores decreased with decreasing pore diameter. Crystallization of pure water within the pores was not observed in samples with pore diameters of 2.2 and 1.4 nm. In the aqueous solution, the glass transition was observed, and the temperature was not dependent on pore diameter and NaCl concentration.
