Solute Effects on the Helix-Coil Transition [PDF]
We discuss the effects of the solvent composition on the helix-coil transition of a polypeptide chain. We use a simple model to demonstrate that improving the hydrogen-bonding ability of the solvent can make the transition less cooperative, without ...

Porosity and morphology control of mesoporous Cu-BTC Metal-Organic Framework microparticles [PDF]
In this study, Cu-BTC structures, one of the most widely used metal-organic frameworks (MOF), were synthesized by solvothermal technique, and the effect of metal-to-ligand ratio and the solvent content on their crystalline structure, chemical bonding ...

Coupling hydrophobic, dispersion, and electrostatic contributions in continuum solvent models [PDF]
Recent studies of the hydration of micro- and nanoscale solutes have demonstrated a strong {\it coupling} between hydrophobic, dispersion and electrostatic contributions, a fact not accounted for in current implicit solvent models.

We investigate local phase transitions of the solvent in the neighborhood of a solvophobic polymer chain which is induced by a change of the polymer-solvent repulsion and the solvent pressure in the bulk solution.

Solvent mediated interactions between model colloids and interfaces: A microscopic approach [PDF]
We determine the solvent mediated contribution to the effective potentials for model colloidal or nano- particles dispersed in a binary solvent that exhibits fluid-fluid phase separation.

Critical Casimir forces and colloidal aggregation: A numerical study
We present a numerical study of the effective potential $V_\mathrm{eff}$ between two hard-sphere colloids dispersed in a solvent of interacting particles, for several values of temperature and solvent density, approaching the solvent gas-liquid critical ...
