摘要
The capabilities of an upgraded photopyroelectric calorimetric setup to perform simultaneous evaluations of thermal and optical parameters for a more comprehensive evaluation of several phase transition studies are reported. It has been applied to the study of the nematic-isotropic phase transition of an 8CB liquid crystal hosted in a network of silica nanoparticles, of the sol-gel transition in hydrated parchment fibers and of the nematic-isotropic and the smecticA-nematic transitions of 8CB liquid crystal with inclusions of photochromic molecules.
