Newly synthesized Polypropylene-g-Polyethylene glycol polymer was first time used for a compartment-less enzymatic fuel cell. Working electrodes based on Polypropylene-g-Polyethylene glycol were operated as unmediated and mediated system (with ferrocene and gold/cobalt oxide nanoparticles). Glucose oxidase and bilirubin oxidase was selected as anodic and cathodic enzyme, respectively. Glucose w...

Polyethylene is widely used as a packing material for different purposes of human life. Accumulation of polyethylene in the environment may cause ecological threat. To prevent the accumulation of polyethylene in the environment, a total of seven actinomycetes were isolated from Koringa Mangrove sediments, near Kakinada, Andhra Pradesh. These isolates were able to grow on mineral salts medium co...

Purpose: Venlafaxine hydrochloride sustained release formulation increases patient compliance by reducing frequency of administration and it also reduces side effects like nausea and vomiting. Hence the objective of present investigation was to develop triple layer sustained release tablets of venlafaxine HCl using xanthan gum or polyethylene oxide. Methods: The venlafaxine HCl 150 mg sustained...

in this study, magnetic iron oxide nanoparticles (fe3o4) with the size range of 20-30 nm were prepared by the modified controlled chemical co-precipitation method from the solution of ferrous/ferric mixed salt-solution in alkaline medium. in this process polyethylene glycol was used as a surfactant to prevent the solution from agglomeration. the prepared magnetic nanoparticles were characterize...

The aim of this study was to develop a multilayer (core/coat) dosage form via co-extrusion, the core providing sustained drug release and the coat immediate drug release. In this study polymers were selected which can be combined in a co-extruded dosage form. Several thermoplastic polymers were hot-melt extruded and evaluated for processability and macroscopic properties (surface smoothness, di...

The spreading of aqueous dispersions of trisiloxane with various polyethylene oxide chain length surfactant solutions over hydrophobic surfaces is considered from experimental point of view. It is shown that the transfer of surfactant molecules from the droplet onto the hydrophobic surface changes the wetting characteristics in front of the drop making them useful in waterbased coatings for pla...
