The aim of the present paper is to study the flow of nanofluid and heat transfer characteristics between two horizontal plates in a rotating system. The lower plate is a stretching sheet and the upper one is a solid porous plate. Copper Cu as nanoparticle and water as its base fluid have been considered. The governing partial differential equations with the corresponding boundary conditions are...

In this study, chitosan (CS)/poly(vinyl alcohol) (PVA) (CS/PVA) blend nanofibers with varying weight ratios and silver (Ag)/copper (Cu)/CS/PVA composite fibers have been prepared successfully by the electrospinning process. The tip-to-collector distance was kept at 15 cm, applied voltage varied from to 25 kV. effects of on morphology diameter were investigated. resultant characterized using sca...

Background: Re-epithelialization has an important role in skin wound healing. Delays in re-epithelialization are more likely to create the chronic wound. Impaired wound healing leads to a large burden of morbidity and mortality. Current treatments based on the use of autografts, allografts and xenografts, suffer from limitations such as, quantity of donor skin available, donor-site infection, p...

Biomolecular templates provide an excellent potential tool for bottom-up device fabrication. Self-assembling alpha-synuclein protein fibrils, the formation of which has been linked to Parkinson's disease, have yet to be explored for potential device fabrication. In this paper, alpha-synuclein fibrils were used as a template for palladium (Pd), gold (Au) and copper (Cu) nanoparticle chains synth...

Plasmonic resonances in metallic nanoparticles have been used since antiquity to colour glasses. The use of metal nanostructures for surface colourization has attracted considerable interest following recent developments in plasmonics. However, current top-down colourization methods are not ideally suited to large-scale industrial applications. Here we use a bottom-up approach where picosecond ...

Metal ions accumulate in the brain with aging and in several neurodegenerative diseases. Aside from the copper storage disease, Wilson's disease, recent attention has focused on the accumulation of zinc, copper and iron in the Alzheimer's disease (AD) brain and the accumulation of iron in Parkinson's disease. In particular, the parenchymal deposition of beta-amyloid (Abeta) and its interaction ...

Abstract For many decades, Cu 2+ ions have been used as fungicides in agriculture. However, the accumulation of soil ecosystem will be disadvantage for environment. Thus, substitution copper nanoparticles ion is necessary to develop long-term efficient, eco-friendly, and cost-effective fungicides. In this study, were synthesized by chemical reduction method with reductive agent NaHB 4 chitosan ...

Introduction: The MRI detection of superparamagnetic iron-oxide particles (SPIO) -labeled cells is important in cell-replacement therapies, which can help monitoring the migration/proliferation of cells following the transplantation. Cells loaded with SPIOs cause signal reduction (negative contrast) associated with dephasing due to the magnetic field inhomogeneity near the cells, therefore the ...
