Abstract: The phase transitions of melting and crystallization of dimethylsulfoxide in porous glasses with different pore sizes have been studied using differential scanning calorimetry. The influence of size effects on characteristics of the transitions is revealed. The linear nature of the dependence of the melting temperature shift on the inverse pore radius is established.

Keywords: dimethylsulfoxide, phase transitions, nanoparticles, size effects.
