Thermodynamic stability of Sm2TeO6

Thermochimica Acta, 2008
Abstract 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

Global and Local Thermodynamic Stability

Journal of Non-Equilibrium Thermodynamics, 1999
An 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 stabilization of nanocrystallinity

Zeitschrift für Metallkunde, 2005
Abstract Nanocrystalline materials are polycrystals made up of nanometer-sized grains separated by a network of interfaces – grain or phase boundaries – that generally make a positive contribution to the total energy of the system. Consequently, there exists a thermodynamic driving force for reducing the overall interface area, which ...

Thermodynamic stability of Sr2CeO4

Thermochimica Acta, 2006
Abstract 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 SrCeO3

Journal of Solid State Chemistry, 2004
Abstract Thermochemistry of the reaction between SrCO3 and CeO2 as SrCO 3 (s)+CeO 2 (s)=SrCeO 3 (s)+CO 2 (g) was studied over the temperature range 1113–1184 K. The equilibrium pressure of CO2(g) over the ternary phase mixture of SrCO3(s), CeO2(s) and SrCeO3(s) was measured at various temperatures using a ...

Thermodynamic stability of CaRuO3

Journal of Alloys and Compounds, 1991
Abstract 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.

On the thermodynamic stability of liposomes

Journal of Colloid and Interface Science, 1990
Abstract The spontancity of liposome formation and their thermodynamic stability are discussed. It is shown that in general liposomes do not form spontaneously and that some energy input is required to prepare them. This clearly illustrates that their free energy is not the minimum the system can achieve even though they can be made stable for ...
