Investigation of Thermodynamic Properties of Heavy Metals from Melting and Critical Point Properties [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2015
A statistical mechanical based equation of state has been employed to calculate the liquid density of lead, mercury, bismuth and lead-bismuth and lead-lithium eutectic alloys.The equation is basically that of Song, Mason and Ihm [Ihm G, Song Y, Mason EA.

Photodynamics of clusters of the major components of the atmosphere

open access: yesInternational Journal of Photoenergy, 2004
Weakly interacting molecules leading to collisional complexes, and to either stable or metastable dimers, potentially play an important role in molecular and surface physics, in astrophysics, in atmospheric photochemistry and physics, and climate ...

Formation of dimers in polar gases: contribution of metastably bound molecules to the second virial coefficient

open access: yes, 1967
The contribution of metastably bound double molecules to the second virial coefficient B(T) of a polar gas has been calculated by assuming the dipoles to be in the head-to-tail position.

Chiral liquid-crystalline polyacrylates from (S)-(-)-2-methyl-1-butanol. Synthesis, mesomorphic properties and light scattering

open access: yesJournal of the Brazilian Chemical Society, 2001
The synthesis and mesomorphic behavior of two chiral side chain liquid crystalline polyacrylates from (S)-(-)-2-methyl-1-butanol are described. These new polyacrylates show a dependence of the phase transition temperatures on both, molecular weight and ...

Interest of the normalized second virial coefficient and interaction potentials for crystallizing large macromolecules

open access: yes, 2002
International audienceIt has been shown for several years that the second virial coefficient, A(2), can be helpfully used to describe the thermodynamic behavior of biological macromolecules in solution prior to crystallization.

Second virial coefficient in one dimension as a function of asymptotic quantities

open access: yes, 2005
PTHA result from Dodd and Gibbs (J. Math. Phys., 15, 41 (1974)) for the second virial coefficient of particles in one dimension, subject to delta-function interactions, has been obtained by direct integration of the wave functions.
