This work makes an investigation of Polyvinyl Alcohol (PVA)/Polyvinyl Pyrrolidone (PVP) composite scattered by copper oxide nanoparticles. Spectroscopic techniques have been utilized for studying the mechanism reaction between PVA/PVP and CuO NPs. Cell viability antibacterial assessment are used investigating activity nanocomposite systems. XRD FTIR-ATR approved complexation miscibility PVA, PV...

The objective of this work was to study the effect of concentration and viscosity grade of HPMC, different diluents and inclusion of solid dispersions on the matrix tablets of aceclofenac. In present study, aceclofenac, a novel NSAID used for symptomatic treatment of pain and inflammation was formulated into matrix tablets with HPMC of two different viscosity grades (E50 LV and K15 M) by direct...

The effect of solvent power and flow rate on the permeability of a size exclusion chromatography (SEC) column packed with a novel polyvinylpyrrolidone (PVP)-grafted porous silica resin was studied. The PVP-silica resin was prepared from a porous silica size exclusion resin onto which a terminally anchored PVP layer was graft polymerized. The terminally anchored PVP layer was synthesized via a f...

various concentrations of copper were embedded into silica matrix to xerogel forms using copper source cu(no3)2∙3h2o. the xerogel samples were prepared by hydrolysis and condensation of tetraethyl ortho-silicate (teos) with determination of new molar ratio of the components by the sol-gel method. after ambient drying, the xerogel samples were heated from 60 to 1000˚c at a slow heating rate (50°...

effects of formulation parameters on the fractional release profile of diclofenac sodium from matrices having the manufacturing formulation ingredients are studied. as a content of cetyl alcohol (rate controlling agent) in the matrix increases, the fractional release decreases. the fractional release increases either by increasing sucrose content outside the granule or by decreasing sucrose con...

Copper has two key properties that are being exploited in consumer and medical device products in the last decade. On the one hand, copper has potent biocidal properties. On the other hand, copper is involved in numerous physiological and metabolic processes critical for the appropriate functioning of almost all tissues in the human body. In the skin, copper is involved in the synthesis and sta...

Our long-term goal is to develop a hybrid cellulose-copper nanoparticle material as a functional nanofiller to be incorporated in thermoplastic resins for efficiently improving their antimicrobial properties. In this study, copper nanoparticles were first synthesized through chemical reduction of cupric ions on TEMPO nanofibrillated cellulose (TNFC) template using borohydride as a copper reduci...
