Preparation of Silver - Coated Polystyrene Composite Particles
We report a feasible approach to the preparation of monodispersed metal-shell composite microspheres based on a combination of surface reaction and surface seeding techniques. The method was implemented for coating polystyrene (PS) spheres with silver shell having a variable thickness by controlling the amount of reagents in the reaction procedure. These composite spherical particles in dimensi...

15 صفحه اولSolid state preparation of CdO nano-particles by thermolysis of a precursor as compacted nanosheet
A novel complex of cadmium (II) [CdL0.5(NO3)(H2O)](1), L= N,N-bis (O-hydroxyacetophenone) ethylene diamine, have been synthesized as single crystal and nano size. Compound 1 in nano size was obtained under sonochemical irradiation and has been characterized by IR, 1HNMR spectroscopy, X-ray powder diffraction (XRD) and scanni...

متن کاملTheophylline-Ethylcellulose Microparticles: Screening of the Process and Formulation Variables for Preparation of Sustained Release Particles
Objective(s) The aim of this study was to formulate and evaluate microencapsulated controlled release preparations of theophylline using ethylcellulose as the retardant material with high entrapment efficiency. Materials and Methods Microspheres were prepared by water-in-oil-in-oil (W/O1/O2) emulsion-solvent diffusion (ESD). A mixed solvent system consisting of acetonitrile and dichloromet...
