Canonical equilibrium distribution derived from Helmholtz potential
Oikonomou, Thomas; Baris Bagci, G.; Tirnakli, Ugur - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 24, pp. 6386-6389
Plastino and Curado [A. Plastino, E.M.F. Curado, Phys. Rev. E 72 (2005) 047103] recently determined the equilibrium probability distribution for the canonical ensemble using only phenomenological thermodynamical laws as an alternative to the entropy maximization procedure of Jaynes. In the...

High performance high-purity sol-gel derived carbon supercapacitors from renewable sources
Garcia, Betzaida Batalla; Candelaria, Stephanie L.; … - In: Renewable Energy 36 (2011) 6, pp. 1788-1794
In this study highly pure carbons synthesized using resorcinol furaldehyde catalyzed with hexamethylenetetramine (an amine base) are tested for supercapacitor electrodes. This synthesis is not only from all-organic renewable sources, but can also significantly increase the performance of the...

Random-walk diffusion and drying of porous materials
Mehrafarin, M.; Faghihi, M. - In: Physica A: Statistical Mechanics and its Applications 301 (2001) 1, pp. 163-168
Based on random-walk diffusion, a microscopic model for drying is proposed to explain the characteristic features of the drying-rate curve of porous materials. The constant drying-rate period is considered as a normal diffusion process. The transition to the falling-rate regime is attributed to...

Mechanistic investigation into water tolerance of non-catalytic biodiesel conversion
Kwon, Eilhann E.; Yi, Haakrho; Jeon, Young Jae - In: Applied Energy 112 (2013) C, pp. 388-392
This study provides a systematic approach to understand the water tolerance of a newly developed non-catalytic biodiesel conversion process. The influence of water on the non-catalytic biodiesel conversion process was compared directly with the conventional transesterification reaction, which...
