the purpose of this work was to develop once daily sustained release (sr) matrix tablets of naproxen, an anti-inflammatory agent. the tablets were prepared by wet granulation method along with hydrophilic matrix materials like methocel k 15m cr and methocel k 100m cr. the granules were evaluated for bulk density, angle of repose, compressibility index, total porosity and drug content. the table...

Electrodeposition is a simple and economic technique for precision coating of different shaped substrates with pure metal, alloy or composite films. Dc electrodeposition was used to produce Cr, Co-Cr and Co-Cr/TiO2 nano-composite coatings from Cr(III) based electrolytes onto 316L SS substrates. The effects of TiO2 nanoparticles concentration on co-deposition of these particles along with Cr con...

In this study, the retention substance bentonite was used in preparation of a mesoporous silica nanocatalyst. The analysis sorbents from sorption isotherm study and results obtained were summarized. Also discussed are chemical composition Navbahor deposit, types sorbent isotherms by adsorption various gases on sorbents, descriptions phase samples synthesized textures, physic-chemical characteri...
