Bacterial and viral contamination of touch surfaces allows for transmission of pathogens leading to increased risk of infection. Previous work has demonstrated the antimicrobial properties of copper for contact-killing of microbes for use in hospitals. Less research exists on copper as an antiviral surface and on the effects of nanomaterial copper surfaces in the contact-killing of viruses. Nan...

Nano-scale copper oxide with various morphologies is synthesized via the thermal oxide method and growth in a 5 wt% NaCl solution of spray fog environment. The nano-scale copper oxide is grown on copper metal sheets via the thermal oxide method at 650 ̊C for 60 minutes. Nano-scale copper oxide grains and nanowires are induced on copper metal sheets then placed in 5 wt% NaCl solution of salt spra...

Nano-Al₂O₃ has been widely used in various industries; unfortunately, it can be released into the aquatic environment. Although nano-Al₂O₃ is believed to be of low toxicity, it can interact with other pollutants in water, such as heavy metals. However, the interactions between nano-Al₂O₃ and heavy metals as well as the effect of nano-Al₂O₃ on the toxicity of the metals have been rarely investig...

The demand for new, thermally conducting light weight and anti-corrosive materials is tried by incorporating Copper Oxide (CuO) nano powder in polyethylene matrix material. A laboratory level electro deposition technique is adopted here to prepare Copper Oxide (CuO) nano particles. Their phase composition is confirmed with X-Ray diffraction peaks and verified with standard JCPDS file for Copper...

BACKGROUND AND AIM Nanoparticles can bypass conventional physiological ways of nutrient distribution and transport across tissue and cell membranes, as well as protect compounds against destruction prior to reaching their targets. In ovo administration of nanoparticles, may be seen as a new method of nano-nutrition, providing embryos with an additional quantity of nutrients. The aim of the stud...

Background and purpose: Copper is a trace element that is used in various industries. Copper nano-particles are being used in different skin care products, lubricants, oils, polymers, metal covers, plastics, inks, etc. Previous studies have shown that both copper sulfate and copper nano-particles can induce cellular genotoxicity and DNA damage. So, this study aimed at evaluating and comparing g...

This research deals with the synthesis of nanosized copper as colloidal solution and its application to cotton fabric. Copper nano colloids were prepared by chemical reduction of copper salt using sodium borohydride as reducing agent in presence of trisodium citrate. The size and size distribution of the particles were examined by particle size analyzer and the morphology of the synthesized par...

Nano-copper(0) stabilized on alumina prepared from Cu-Al hydrotalcite has been reported for completely regioselective synthesis of 2,4-disubstituted pyrroles from unactivated terminal aromatic/aliphatic alkynes and isocyanides. The reaction is operationally simple, involves ligand-free inexpensive nano-copper, and affords products in high yields.

The deposition of nano-size copper particles was carried out by means of ink-jet printing on the ceramic substrate (silicon and faience) using Nd +3 :YAG laser. Glycerin and aqueous based nano copper inks were prepared and were inkjetted in this study. The sintered copper film had a grainy structure with neck-like junctions. The microstructure and soldering properties were examined using XRD, S...

A copper/low-density polyethylene nanocomposite (nano-Cu/LDPE), a potential intrauterine device component material, has been developed from our research. A logical extension of our previous work, this study was conducted to investigate the expression of plasminogen activator inhibitor 1 (PAI-1), substance P (SP), and substance P receptor (SP-R) in the endometrium of Sprague Dawley rats, New Zea...
