Exciton harvesting is of fundamental importance for the efficient operation of organic photovoltaic devices. The quantum efficiencies of many organic and hybrid organicinorganic devices are still limited by low exciton harvesting efficiencies. This problem is most apparent in planar heterostructures that suffer from a direct tradeoff between light absorption and exciton harvesting. One approach...

We have fabricated new types of polymer hydrogels and polymer nanocomposites, that is, nanocomposite gels (NC gels) and soft polymer nanocomposites (M-NCs), with novel organic/inorganic network structures. Both NC gels and M-NCs were synthesized by in situ free-radical polymerization in the presence of exfoliated clay platelets in aqueous systems and were obtained in various forms and sizes wit...

The efficiencies of both organic and hybrid (organicinorganic) solar cells have increased markedly in recent years, making them an exciting and commercially valuable prospect. Despite this progress, a literature survey that we have performed suggests that a large number of reported solar cell efficiencies are being incorrectly measured and reported in journals, with the device efficiency being ...

the processes of cultural transformation in britain in the second half of the 20th century, the fall of the empire, immigration from former colonies and the expansion of the multiculturalism, have influenced new ways of looking at the conceptions of identity of diasporic subjects within britain. examining these experiences, diasporic novelists write about the second generation immigrants in con...

background the prevalence of peptic ulcer disease in hemodialysis patients is more than the general population. they are also more prone to complications including upper gastrointestinal bleeding. the aim of this study was to compare the efficacy of 14 days hybrid regimen with 14 days triple therapy for helicobacter pylori ( h . pylori ) eradication in hemodialysis patients. methods forty hemod...

this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

the share of dc-based renewable energy resources (rers) and electricity storage systems are increasing due to developments of smart grid technologies. moreover, the share of dc-based load has rapid growth due to significant developments of power electronic technologies. therefore, a more flexible power system is required for efficient integration of emerging loads and generators. in this paper,...
