Electrocaloric Effect in Triglycine Sulfate under Equilibrium and Nonequilibrium Thermodynamic Conditions
The direct and indirect measurements of intensive electrocaloric effect in a triglycine sulfate ferroelectric crystal are performed under equilibrium and nonequilibrium thermodynamic conditions implemented in ...
Specific Heat and Thermal Expansion of Triglycine Sulfate-Porous Glass Nanocomposites
The effect of restricted geometry on specific heat capacity and thermal expansion of the triglycine sulfate (TGS)-borosilicate glass composites have been studied first. A decrease in the entropy and temperature of the P2(1) ...
Effect of Deuteration on Phase Transitions in Vanadium Dioxotetrafluoride
The crystals of (ND4)3VO2F4 with a high degree of deuteration (~87%) have been grown and a significant (~1.5%) increase in the unit cell volume has been detected. The decrease in the chemical pressure leads to a change in ...
Study of the Physical Properties and Electrocaloric Effect in the BaTiO3 Nano- and Microceramics
The specific heat, thermal expansion, permittivity, and electrocaloric effect in bulk of BaTiO3 (BT) samples in the form of nano- (nBT-500 nm) and micro- (mBT-1200 nm) ceramics fabricated using spark plasma sintering and ...
