THE LAWS OF THERMODYNAMICS AND THERMODYNAMIC STABILITY OF THE MODIFIED CHAPLYGIN GAS
Modern Physics Letters A, 2010Laws of thermodynamics have been examined for the universe filled with a perfect fluid, obeying an adiabatic equation of state p = γρ-A/ρα (called modified Chaplygin gas), where γ, A and α are positive constants and ρ and p are energy density and thermodynamic pressure respectively.

Thermodynamic stability of biomolecules and evolution
Journal of Theoretical Biology, 2017The thermodynamic stability of biomolecules in the perspective of evolution is a complex issue and needs discussion. Intra molecular bonds maintain the structure and the state of internal energy (E) of a biomolecule at "local minima". In this communication, possibility of loss in internal energy level of a biomolecule through the changes in the bonds ...

Thermodynamic stability of Pt8V
Journal of Alloys and Compounds, 2006Abstract The thermodynamic stability of the ordered Pt 8 V phase has been experimentally investigated for the first time. Pt 8 V is shown to be stable but the ordering kinetics are sluggish, in common with other A 8 B phases. The order–disorder temperature T c is determined to be 810 ± 10 °C.

Global and Local Thermodynamic Stability
Journal of Non-Equilibrium Thermodynamics, 1999An attempt to relate the local dynamics of the stability and the global behavior of thermodynamic stability is presented through the study of the heat conduction in an infinite unidimensional solid bar. The problem is solved analytically in order to conclude that the structures are independent of the sign of the perturbation and the show that the ...

Thermodynamic stability of Sr2CeO4
Thermochimica Acta, 2006Abstract Thermochemistry of the reaction between SrCO 3 and SrCeO 3, represented as SrCO 3 (s) + SrCeO 3 (s) = Sr 2 CeO 4 (s) + CO 2 (g), was studied over the temperature range 1035–1135 K. The equilibrium pressure of CO 2 (g) over the ternary phase mixture of SrCO 3 (s), SrCeO 3 (s) and Sr 2 CeO 4 (s) was measured at various temperatures by ...

Thermodynamic stability of Sm2TeO6
Thermochimica Acta, 2008Abstract The vapour pressure of Sm2TeO6 was measured using a thermal analyser with a horizontal arm. This TG based transpiration technique, was validated by measuring the vapour pressure of pure TeO2(s). The temperature dependence of the latter was measured to be log p (Pa) = {14.2 − 13321/T (K)} (±0.03) in the range 884–987 K. These data yielded a

Thermodynamic stability of CaRuO3
Journal of Alloys and Compounds, 1991Abstract The e.m.f. of the galvanic cell Pt, CaO, CaRuO 3 , Ru|15 CSZ|O 2 ( P O 2 = 0.21 atm), Pt was studied over the range 971–1312 K using 15wt.%CaO-stabilized ZrO 2 (15 CSZ) as the solid electrolyte. This study yielded the least-squares expression E (1) = 754.16−0.36659 T ±1.70 mV.

Thermodynamic States and Their Stabilities
2023A cursory survey of laws of thermodynamics relevant to the problems of phase transformations is given. Although similar information can be found in other textbooks, e.g., [1], the succinct presentation of the basic ideas and methods is helpful for understanding the general concepts in phase transformations.
