nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. copper oxide nano materials are of interest on account of their potential uses in many technological fields. in this study  cuo nanoparticles were synthesized via simple sol gel method using basic cuso4 as we...

The present study investigated the effects of exposure to metal oxide nanoparticles on vasculogenesis/angiogenesis using transgenic zebrafish. The study also examined the potential mechanisms involved in those effects using human umbilical vein endothelial cells (HUVEC). TG (nacre/fli1:EGFP) zebrafish were exposed to nano-sized titanium dioxide (TiO2), silica dioxide (SiO2), and copper oxide (C...

The increasing industrial application of metal oxide Engineered Nano-Particles (ENPs) is likely to increase their environmental release to soils. While the potential of metal oxide ENPs as environmental toxicants has been shown, lack of suitable control treatments have compromised the power of many previous assessments. We evaluated the ecotoxicity of ENP (nano) forms of Zn and Cu oxides in two...

copper sulfate was used as a precursor to prepare cuo nanoparticles in reverse micelles (o/w microemulsion).  this is a technique which allows the preparation of ultrafine metal oxide nanoparticles within the size ranging from 50 to 60 nm. the preparation of nano copper (ii) oxide studied was investigated in the inverse microemulsion system. therefore the nucleation of metal particles proceeds ...

Nano-metallic oxide particles have been found to be potentially effective microstructural reinforcements for cement mortar and become a research hotspot in recent years nano-modification technology of building materials. However, different conclusions obtained due various researchers used methods, which resulted deficiency the performance comparison between nano-metallic particles. In present s...

Several studies have reported the adverse effects of nano-CuO on hippocampal CA1 neuron, whereas little has been known about nano-CuO neurotoxicity in vivo. In the present study, we investigated the effects of nano-CuO on spatial cognition and electrophysiological alterations in rats. In addition, histological and biochemical changes in rat's hippocampus were measured as well. Morris water maze...

Nano-structured CuO-Cu2O complex thin film-based perovskite solar cells were fabricated on an indium tin oxide (ITO)-coated glass and studied. Copper (Cu) thin films with a purity of 99.995 % were deposited on an ITO-coated glass by magnetron reactive sputtering. To optimize the properties of the nano-structured CuO-Cu2O complex thin films, the deposited Cu thin films were thermally oxidized at...

BACKGROUND Marine sponge/nano-CuO as a natural catalyst efficiently catalyzed the Sulfonylation reaction of p-chlorobenzene sulfonyl chlorides with amines in order to prepare sulfonamides. The advantages included use of a natural catalyst, ease of handling, requirement of a very small amount of catalyst, mild reaction condition and appropriateness to high yield. OBJECTIVES The current study a...
