Polymer solar cells, a highly innovative research area for the last decade until today, are currently maturing with respect to understanding of their fundamental processes of operation. The increasing interest of the scientific community is well reflected by the—every year—dynamically rising number of publications. This chapter presents an overview of the developments in organic photovoltaics e...

Results: The experimental results showed that the recovery of variable concentrations polymer flooding was higher than that of constant concentration polymer flooding, under conditions of same total amount of polymer and similar water flooding recovery. Its sweep efficiency and displacement efficiency were also significantly higher than those of constant concentration polymer flooding. Moreover...

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...
