Integral equation study of the solvation force between macroscopic surfaces separated by thin films of diatomic, chain, and network solvents
Article Abstract:
A study of the effects of the nonsphericality of solvent molecules was conducted using the simple models of associating fluids in the singlet approach of internal equation theory. The derived results were found to be capable of qualitatively reproducing the most important experimentally observed characteristics of the solvation force. Negative solvation forces were observed between macroscopic surfaces in linear chain solvents while the solvation forces in the network solvent are observed to be almost monotonic, repulsive and positive at short separations.

Adsorption of dimerizing and dimer fluids in disordered porous media
Article Abstract:
The associative extension of replica Ornstein-Zernike (ROZ) equations were used for a simple, hard-sphere fluid model that allowed dimerization of particles as a result of the associative site-site interaction. The main purpose of the study was to analyze the accuracy of theoretical results acquired with the associative hypernetted chain (HNC) approximation and Percus-Yevick (PY) approximation against computer simulations. The HNC closure was more superior in solving the equations than the PY closure.

Optical pumping of dye-complexed and -sensitized porous silicon increasing photoluminescence emission rates
Article Abstract:
A study was conducted to analyze energy transfer from porous silicon to a very limited group of impregnating dyes supporting negligible absorbance at wavelengths commensurate with the porous silicon excitation spectrum. Porous silicon samples were prepared in an electrochemical cell made from high-density polyethylene. Results indicated that the degree of porous silicon-dye interaction was porous silicon-structure dependent.
