2014 We report results of light scattering study of interactions in a mixture of a surfactantstabilized colloid and hydrogenated polyisoprene polymer. With a virial expansion the smallangle scattering intensity from the mixture is calculated as a function of colloid and polymer concentrations. Using the obtained formula we measured the mutual excluded volume between a polymer molecule and a col...

New model xDLVO-CGhybr calculating second osmotic virial coefficient of protein solutions is developed. Data calculated agrees well with experiments due to accurate estimation electrostatic protein–protein interactions using a hybrid methodology.

An interaction potential at different orientation for the CH4 and CO2 complex was derived at theB3LYP level of theory and 6-31+G* basis sets. The potential energy surface was computed on somemolecular geometries. The complete basis set limit of the interaction energies were fitted to wellknownanalytical functions. To determine the second virial coefficients B, U(r) is used to obtain themodel’s ...
