Rubrene, perylene, -quaterthiophene, and tetracene single crystals were grown and placed between indiumtin-oxide and Al electrodes; the current-voltage characteristics of the so-fabricated two-terminal organic devices were measured at ambient conditions under solar simulator illumination. While rubrene single crystals do not exhibit any photovoltaic effect, open-circuit voltages reach values up...

background: fluoride is used increasingly in a variety of industries in india. emission of fluoride dust and fumes from the smelters of primary aluminum producing industries is dissipated in the work environment and poses occupational health hazards. objective: to study the prevalence of health complaints and its association with fluoride level in body fluids of smelter workers in a primary alu...

Studying the properties of structures where at least one spatial dimension is on the nanometer scale is motivated by many factors from engineering (such as the semiconductor industry’s push towards higher density integrated circuits), chemistry (developing methods to produce particles of well controlled size and structure), biology (using DNA to control the self-assembly of small structures) an...

one of the important bottle-necks in production of microalgae based biodiesel is thelack of an efficient method for harvesting of microalgae from the culture medium. in thisstudy, the electroflocculation method was developed for harvesting of microalgaedunaliella cells from culture medium. the effect of several parameters such as thecurrent density, electrical conductivity of culture medium, ti...

background & aims of the study: detergent and phosphate are one of the main and vital threats (eutrophication phenomenon and production of synthetic foam) for the source of drinking water, agriculture and industrial uses in the ahvaz, iran that threaten human health. the aim of this study is the evaluation of the efficiency of the electrocoagulation (ec) process in the removal of detergent and ...

Rational design of active electrode materials is important for the development of advanced lithium and post-lithium batteries. Ab initio modeling can provide mechanistic understanding of the performance of prospective materials and guide design. We review our recent comparative ab initio studies of lithium, sodium, potassium, magnesium, and aluminum interactions with different phases of several...
