Discrete solvent effects on the effective interaction between charged colloids [PDF]

open access: yes, 2000
Using computer simulations of two charged colloidal spheres with their counterions in a hard sphere solvent, we show that the granular nature of the solvent significantly influences the effective colloidal interaction. For divalent counterions, the total

Critical Casimir Forces and Colloidal Phase Transitions in a Near-Critical Solvent : A Simple Model Reveals a Rich Phase Diagram [PDF]

open access: yes, 2014
From experimental studies it is well-known that colloidal particles suspended in a near-critical binary solvent exhibit interesting aggregation phenomena, often associated with colloidal phase transitions, and assumed to be driven by long-ranged solvent ...

Modeling the absorption spectrum of the permanganate ion in vacuum and in aqueous solution [PDF]

open access: yes, 2017
The absorption spectrum of the MnO$_{4}$$^{-}$ ion has been a test-bed for quantum-chemical methods over the last decades. Its correct description requires highly-correlated multiconfigurational methods, which are incompatible with the inclusion of ...

Effect of the environment on the electrical conductance of the single benzene-1,4-diamine molecule junction

open access: yesBeilstein Journal of Nanotechnology, 2011
We investigated the effect of the environment on the electrical conductance of a single benzene-1,4-diamine (BDA) molecule bridging Au electrodes, using the scanning tunneling microscope (STM).

Porosity and morphology control of mesoporous Cu-BTC Metal-Organic Framework microparticles [PDF]

open access: yesProgress in Physics of Applied Materials
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 ...

The local phase transitions of the solvent in the neighborhood of a solvophobic polymer at high pressures

open access: yes, 2014
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]

open access: yes, 2009
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.

Optimisation of solvent replacement procedures according to economic and environmental criteria in pharmaceutical industry [PDF]

open access: yes, 2006
During pharmaceutical syntheses, the reaction solvent has often to be switched off from one reaction step to the following one. Because of the standard industrial practices, solvent replacement generally constitutes a slow and high solvent-consuming ...
