The papers discuss the features of clustering in aqueous solutions ethanol. It is assumed that volume an elementary cluster smaller than total molecular volumes components make up this cluster. justified form concentration dependence parameter. Based on data composition water-ethanol solutions, was obtained. value determination accuracy does not worse . Applying group description molar solution...

We report on the development of force-field parameters for accurately modeling lithium and hydroxide ions in ethanol in solution. Based on quantum calculations of small molecular clusters mimicking the solvent structure of individual ions as well as the solvated LiOH dimer, significant improvements of off-the-shelf force-fields are obtained. The quality of our model is demonstrated by compariso...

Transport of liquids by pervaporation takes place by a solution-diffusion mechanism. In order to investigate the “solution part” of this transport model, preferential sorption has been compared with preferential permeability. Sorption equilibria and pervaporation experiments for the systems water-ethanol-cellulose acetate, water-ethanol-polyacrylonitrile and water-ethanol-polysulfone have been ...

core-shell nanostructures are emerging as more important materials than alloy nanostructures and have much more interesting potential applications in various fields. in this work, we demonstrated the fast and facile synthesis of core-shell nanoparticles consisting of pt thin layer as the shell and ni nanoparticles as the cores. the described method herein is suitable for large-scale and low-cos...
