Solvent size effects on the depletion layer of a polymer solution near an interface

Article Abstract:

The effect of solvent size on the depletion interaction between polymer coils and a hard wall was investigated by the real-space version of self-consistent field theory (SCFT). The results found through analysis of the respective free energies of polymer coils and solvent molecules revealed an increment in the transnational entropy of the solvent is the key to strengthening the depletion interaction.

Treating entropy and conformational changes in implicit solvent simulations of small molecules

Article Abstract:

The magnitude of errors incurred by fixing solutes into the single conformation when computing hydration free energies with implicit solvent models are discussed. The single-conformation hydration free energies have varied depending on the solute conformation and have differed substantially from true hydration free energies computed by using the same parameters.

Controlled electrophoretic deposition of uniquely nanostructured star polymer films

Article Abstract:

The controlled electrophoretic deposition of polystyrene/divinyl/benzene (PS/DVB) star polymer films from a colloidal suspension is demonstrated. The nanostructured films could be utilized in optical and biological device applications.
