CL-20/CAB energetic composite microspheres prepared by premix membrane emulsification

Uniform-sized PLA nanoparticles: preparation by premix membrane emulsification.

Nanoparticle size is crucial to drug release behavior and biodistribution in vivo, but few studies have been performed on biodegradable nanoparticles with narrow size distribution. In this note, uniform-sized nanoparticles were prepared by a facile method combining emulsion-solvent removal and premix membrane emulsification for the first time. After preparation of coarse emulsions, additional p...

Optimization and Evaluation of Monodispersed Tetrandrine-Loaded PLA Microspheres Prepared With A SPG Membrane Emulsification Technique

To improve pulmonary drug concentrations and to maximize the effectiveness and minimize the adverse side effects, uniformsized tetrandrine-loaded polylactide (PLA) microspheres with a suitable particle size for pulmonary inhalation were prepared by the Shirasu Porous Glass (SPG) membrane emulsification technique. The main parameters influencing PLA microsphere properties were investigated: tran...

On the preparation of lecithin-stabilized oil-in-water emulsions by multi-stage premix membrane emulsification

Evaluation of diltiazem hydrochloride-loaded mucoadhesive microspheres prepared by emulsification-internal gelation technique.

The problems of frequent administration and variable low bioavailability (40-60%) after oral administration of conventional dosage forms of diltiazem can be attenuated by designing it in the form of mucoadhesive microspheres which would prolong the residence time at the absorption site to facilitate intimate contact with the absorption surface and thereby improve and enhance the bioavailability...

Electrochemical properties of tungsten sulfide–carbon composite microspheres prepared by spray pyrolysis

Tungsten sulfide (WS2)-carbon composite powders with superior electrochemical properties are prepared by a two-step process. WO3-carbon composite powders were first prepared by conventional spray pyrolysis, and they were then sulfidated to form WS2-carbon powders. Bare WS2 powders are also prepared by sulfidation of bare WO3 powders obtained by spray pyrolysis. Stacked graphitic layers could no...
