Kinetics and thermodynamic parameters of the thermal decomposition of bis(imipraminium)tetrachlorocuprate, bis(imipraminium)tetrachloromercurate and imipraminium reineckate

The phase evolution with temperature in 0.94PbZrO3–0.06Pb(Mg1/2W1/2)O3 antiferroelectric ceramic

“…The enthalpy change was calculated directly from the amount of heat change involved in each step per unit mass of the sample. The H* was thus determined and implemented to calculate the specific heat capacity (C p ) using the following equation [30,31]:…”

“…Consequently, the changes of entropy ( S*) and Gibbs energy ( G*) were calculated using the following equations [30,31]:…”

Effect of BiAlO3 modification on the stability of antiferroelectric phase in PbZrO3 ceramics prepared by conventional solid state reaction

“…The enthalpy change was calculated directly from the amount of heat change involved in each step per unit mass of the sample. H*, thus determined, was implemented to calculate the specific heat capacity (C p ) using the following equation [31,32] …”

Direct polyamidation in green media: Studies on thermal degradation of novel organosoluble and optically active flame retardant polyamides

“…The positive values of DH indicate that the dissociation processes are endothermic in nature and enhanced with the rise of temperature. DG values for the dissociation constants are positive, thus dissociation processes are non-spontaneous[39][40][41].…”
