  • Porous polymer scaffold useful for tissue engineering in stem cell transplantation
    Patent number: 9925298
    Abstract: The present invention relates to the synthesis of porous polymer scaffold from polyethyleneglycol-polyurethane having castor oil linkages under controlled conditions and their use as stem cell delivery vehicles thereby accelerating the tissue regeneration process. The present invention further studies the biodegradability, stability and biocompatibility of porous polymer scaffolds in various cell lines and primary bone marrow stem cells. Particularly the present invention further relates to the physio-chemical characterization of the porous polymer scaffolds.
    Type: Grant

  • HIGH-IONIC CONDUCTIVITY ELECTROLYTE COMPOSITIONS COMPRISING SEMI-INTERPENETRATING POLYMER NETWORKS AND THEIR COMPOSITES
    Publication number: 20160049690
    Abstract: The invention relates to high-ionic conductivity electrolyte compositions. The invention particularly relates to high-ionic conductivity electrolyte compositions of semi-interpenetrating polymer networks and their nanocomposites as quasi-solid/solid electrolyte matrix for energy generation, storage and delivery devices, in particular for hybrid solar cells, rechargeable batteries, capacitors, electrochemical systems and flexible devices. The binary or ternary component semi-interpenetrating polymer network electrolyte composition comprises: a) a polymer network with polyether backbone (component I); b) a low molecular weight linear, branched, hyper-branched polymer or any binary combination of such polymers with preferably non-reactive end groups (component-ll and/or component-Ill, for formation of ternary semi-IPN system); c) an electrolyte salt and/or a redox pair, and optionally d) a bare or surface modified nanostructured material to form a nanocomposite.

  • Process for simultaneous preparation of nanocrystalline anatase titanium dioxide powder and hydrazine monohydrochloride
    Patent number: 7510694
    Abstract: The present invention relates to an environmentally benign process for the simultaneous preparation of nanocrystalline anatase titanium dioxide and hydrazine mohydrochloride, in substantial amounts from the acidic aqueous titanium tetrachloride solution by reacting with hydrazine monohydrate at ambient conditions of temperature and pressure. The process of the present invention is simple, easy to operate, pollution free, high in product purity and homogeneous in product particle.
