Enhanced Drug Dissolution and Bulk Properties of Solid Dispersions Granulated with a Surface Adsorbent

Pharmaceutical Development and Technology, 2001
A combination of solid dispersion and surface adsorption techniques was used to enhance the dissolution of a poorly water-soluble drug, BAY 12-9566. In addition to dissolution enhancement, this method allows compression of the granulated dispersion into tablets. Gelucire 50/13 (polyglycolized glycerides) was used as the solid dispersion carrier.

Characteristic features of the velocity dispersion of surface acoustic waves in anisotropic coated solids

Ultrasonics, 2002
Basic patterns of the velocity versus wavenumber dispersion of the surface waves in solids coated by a relatively light or dense, "slow" or "fast" layer are discussed in the general case of an arbitrary anisotropy of substrate and coating materials.

Dispersion and Attenuation of Surface Acoustic Waves of Various Polarizations on a Stress-Free Randomly Rough Surface of Solid

Annals of Physics, 1995
An approach to obtaining the dispersion equation of surface acoustic waves (SAWs) on a stress-free, randomly rough surface of an anisotropic elastic medium is suggested. The problem is solved in the approximation of a weakly rough surface using Green's function technique. The dispersion and attenuation of sagitally and shear horizontally polarized SAWs

Application of Shereshefsky's equation for the determination of solid surface dispersion energy

Journal of the Chemical Society D: Chemical Communications, 1971
A simple method for obtaining solid surface dispersion energies by measuring adsorption from solution and applying Shereshefsky's equation has been tested with experimental data from the literature on the adsorption of stearic acid from C6H6 solution on to mercury, iron, copper, and nickel giving results that compare favourably with those obtained by ...

A surface-immobilized model compound investigation of catalytic reactions in dispersed solids

Energy & Fuels, 1993
Reactions of the silica-immobilized model compounds, ≃Ph(CH 2 ) n Ph(n = 1, 3, 4) and ≃PhCH 2 CH 2 OPh, with dispersed acid catalysts have been studied at 310-375 °C in the solid state. Reactions of these model compounds in the presence of a small particle size (15 nm) silica-1% alumina catalyst yield products typically expected for acid-catalyzed ...
