In this study the polymer composite specimen has been prepared by using polymer Polyvinylpyrrolidone (PVP) a Potassium iodide (KI) and alumina nanoparticles. The polymer composite specimens were developed by using solution cast techniques. The main objective of the project is to study microstructure, XRD, ionic conductivity, ionic transference number, glass transition temperature using DSC, mic...

We theoretically investigate the ground-state properties of ferromagnetic metal/conjugated polymer interfaces. The work was partially motivated by recent experiments in which injection of spin-polarized electrons from ferromagnetic contacts into thin films of conjugated polymers was reported. We use a one-dimensional nondegenerate Su-Schrieffer-Heeger Hamiltonian to describe the conjugated poly...

We report the design of erodible 'mixed multilayer' coatings fabricated using plasmid DNA and combinations of both hydrolytically degradable and charge-shifting cationic polymer building blocks. Films fabricated layer-by-layer using combinations of a model poly(β-amino ester) (polymer 1) and a model charge-shifting polymer (polymer 2) exhibited DNA release profiles that were substantially diffe...

This paper discusses about preparation of biodegradable polymer /clay nanocomposites based on organically modified montmorillonite clay; i.e. cloisite 10A and biodegradable polymer chitosan by solution mixing technique and their characterization. The nanocomposites were successfully prepared and their structures were characterized by powder x-ray diffraction (XRD), particle size analyzer (Beckm...

A molecularly imprinted polymer for recognising selectively 2,3,7,8tetrachlorodibenzodioxin (TCDD) was made by a new non-covalent method employing a “dummy” template. The proposed way represents a simplification of a synthetic scheme proposed by Lübke et al.[1] for covalent imprinting. Comparison of extraction yields of the novel polymer, a non imprinted polymer and an imprinting polymer, prepa...

biomedical applications of superparamagnetic iron oxide nanoparticles (spions) requiring precise control over their physical and magnetic properties, and proper surface treatment. here we report a practical and effective electrochemical strategy for preparation of the polymer coated spions. in this strategy, in situ polymer coating on the surface of spions was achieved through electrodeposition...
