Practical Broad-Band Tuning of Dye Lasers by Solvent Shifting [PDF]

open access: yes, 1986
We have operated a dye laser over a broad wavelength range (593.8-667.0nm) by shifting the dye emission profile with incremental changes of solvent composition. This was accomplished with the laser operating continuously, and only minor adjustment of the

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

Can scleroderma be induced by anesthetics? Case report

open access: yesMedycyna Pracy, 2016
Occupational exposure to solvents is consistently associated with the risk of systemic sclerosis. We pose the question of whether the occupational exposure to anesthetics may favor the occurrence of this disease.

Solute Effects on the Helix-Coil Transition [PDF]

open access: yes, 2002
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 ...

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.

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 ...

Demixing of colloid-polymer mixtures in poor solvents

open access: yes, 2002
The influence of poor solvent quality on fluid demixing of a model mixture of colloids and nonadsorbing polymers is investigated using density functional theory.

Solvent Mediated Assembly of Nanoparticles Confined in Mesoporous Alumina

open access: yes, 2006
The controlled self-assembly of thiol stabilized gold nanocrystals in a mediating solvent and confined within mesoporous alumina was probed in situ with small angle x-ray scattering.
