ULTRAVIOLET-VISIBLE ABSORPTION SPECTRUM OF C60 VAPOR AND DETERMINATION OF THE C60 VAPORIZATION ENTHALPY
Journal of Chemical Physics, 1994Co-Authors: L. Mac Toth, David H. MetcalfAbstract:Ultraviolet‐visible absorption spectroscopic studies of C60 vapor were carried out in the temperature range 400 °C–720 °C. The enthalpy of sublimation (180±10 kJ/mol) was obtained through the use of the Clausius–Clapeyron Equation.

Clapeyron Equation and phase equilibrium properties in higher dimensional charged topological dilaton AdS black holes with a nonlinear source
The European Physical Journal C, 2017Co-Authors: Hui-hua Zhao, Li-chun Zhang, Ren ZhaoAbstract:Using Maxwell’s equal area law, we discuss the phase transition of higher dimensional charged topological dilaton AdS black hole with a nonlinear source. The coexisting region of the two phases is found and we depict the coexistence region in the P–v diagrams. The two-phase equilibrium curves in the P–T diagrams are plotted, and we take the first order approximation of volume v in the calculation. To better compare with a general thermodynamic system, the Clapeyron Equation is derived for a higher dimensional charged topological black hole with a nonlinear source. The latent heat of an isothermal phase transition is investigated. We also study the effect of the parameters of the black hole on the region of two-phase coexistence. The results show that the black hole may go through a small–large phase transition similar to those of usual non-gravity thermodynamic systems.

Phase transition and Clapeyron Equation of black holes in higher dimensional AdS spacetime
Classical and Quantum Gravity, 2015Co-Authors: Hui-hua Zhao, Li-chun Zhang, Ren ZhaoAbstract:Using Maxwell's equal area law, we study the phase transition in higher dimensional anti-de Sitter (AdS) Reissner–Nordstrom black holes and Kerr black holes in this paper. The coexisting region of the two phases involved in the phase transition is found and some coexisting curves are shown in figures. We also analytically investigate the parameters that affect the phase transition. To better compare with a general thermodynamic system, the Clapeyron Equation is derived for the higher dimensional AdS black holes.

Prediction of the liquid–vapor equilibrium pressure using the quasi‐Gaussian entropy theory
Journal of Chemical Physics, 1996Co-Authors: Andrea Amadei, Danilo Roccatano, M. E. F. Apol, Herman J. C. Berendsen, Alfredo Di NolaAbstract:We derived a method to evaluate the liquid–vapor equilibrium pressure, with high accuracy over a large range of temperature, using the quasi‐Gaussian entropy theory. The final expression that we obtain for the equilibrium pressure as a function of the temperature can be considered as a very accurate approximate solution of the Clausius–Clapeyron Equation. The method was applied to water, methanol and mercury, and was compared to two usual approximations of the Clausius–Clapeyron Equation.
