General description

Electrophoretic mobility of polymethylmethacrylate (PMMA) particles in a low-polar, density- and refractive-index-matched mixture of cyclohexylbromide and cis-decahydronaphthalene was investigated. cis-decahydronaphthalene (cis-DeHN) undergoes zeolite-catalyzed conformational isomerization to trans-DeHN.

We present a method to accurately measure the electrophoretic mobility of spherical colloids at high volume fractions in real space using confocal laser scanning microscopy (CLSM) and particle tracking. We show that for polymethylmethacrylate (PMMA) particles in a low-polar, density-

A modification of the CHARMM36 lipid force field (C36) for cholesterol, henceforth, called C36c, is reported. A fused ring compound, decalin, was used to model the steroid section of cholesterol. For decalin, C36 inaccurately predicts the heat of vaporization (~10

Spontaneous crystalline-to-amorphous phase transformation of organic or medicinal molecules in the presence of mesoporous materials has been observed, for which pathway was suggested to be via the vapor phase, that is, sublimation of the crystalline molecules followed by adsorption on
