The incorporation of copper species is synthesized  in a silica matrix by the sol-gel method. We have doped copper ions and copper particles using two different copper sources: Cu(NO3)2.3H2O and copper particles chemically synthesized. We can prepare the particles of copper metallic, cuprous and cupric oxide and  compare the synthesis and characterization copper species on the silica matrix.  O...

In copper oxide (CuO) based solar cells, various buffer layers such as CdS, In2S3, WS2 and IGZO have been investigated by cell capacitance simulator (SCAPS) in this work. By varying absorber layer thickness, photovoltaic parameters (open circuit voltage, fill factor, short-circuit current density efficiency) are determined. The highest efficiency achieved is 19.6% with layer. impact of temperat...

  Background and aims: Carbon monoxide (CO) is a highly toxic, colorless, and odorless gas with a density close to the air, which is produced by natural processes and anthropogenic sources and is well known for its potential harmful and poisonous effects on humans. Inhalation of carbon monoxide gas can impair the heart and central nervous system. Diatomite supported nano copper oxide catalyst w...

We report the synthesis of copper(II) oxide hollow nanostructures at ambient pressure and close to room temperature by applying the soft templating effect provided by the confinement of droplets in miniemulsion systems. Particle growth can be explained by considering a mechanism that involves both diffusion and reaction control. The catalytic reduction of p-nitrophenol in aqueous media is used ...

Surface chemistry studies of the chemical mechanical planarization ~CMP! of copper are presented in this paper. Blanket copper samples were polished with an acidic alumina-based slurry which contains an organic acid salt ~phthalic acid salt! and an oxidizer (H2O2!. Surface studies using X-ray photoelectron spectroscopy ~XPS! were performed on copper samples after chemical etching or CMP in orde...

Cupric oxide (CuO), having a narrow bandgap of 1.2 eV and a variety of chemophysical properties, is recently attractive in many fields such as energy conversion, optoelectronic devices, and catalyst. Compared with bulk material, the advanced properties of CuO nanostructures have been demonstrated; however, the fact that these materials cannot yet be produced in large scale is an obstacle to rea...

The effect of nanomaterials on biota under realistic environmental conditions is an important question. However, there is still a lack of knowledge on how different illumination conditions alter the toxicity of some photocatalytic nanomaterials. We have investigated how environmentally relevant UV-A exposure (intensity 8.50 ± 0.61 W/m(2), exposure dose 9.0J/cm(2)) affected the toxicity of ceriu...
