Summary: Replacing precious metals with low-cost metals is the best solution for large scale production. In this study, a simple method of depositing nickel-molybdenum oxide and nickel on copper substrates was used to reduce corrosion and improve performance. The alloying of copper with nickel shows great potential as a hydrogen evolution reaction (HER) catalyst.

Summary: Copper is a historically used metal to prevent infections and has potential in combating infectious disease outbreaks. Copper nanoparticles and surfaces are common antimicrobial copper-based technologies. The mechanisms explaining their unique antimicrobial properties are not fully understood, but involve membrane rupture, ion accumulation, protein inactivation, and DNA damage. Understanding the toxicity mechanisms of copper nanoparticles and surfaces is important for developing efficient antimicrobial technologies.

Summary: In this study, copper-coated carbon fibers were prepared using electroplating and the effect of annealing temperature on their electrical conductivity and mechanical properties was investigated. The results demonstrated that annealing reduced the defects in the copper layer and increased the XRD peak intensity and grain size of the copper layer, indicating enhanced crystallinity and reduced grain boundaries. After 20 minutes of annealing, the conductivity of the copper-coated fibers increased by 78 times and improvements were observed in their mechanical properties. The impact of grain boundaries on the electronic transport properties of copper was also studied using computational methods.

Summary: The impedance matching performance of carbon nanotubes can be effectively enhanced by developing a uniform magnetic impedance matching layer, which is critical for achieving desirable microwave absorption performance. By utilizing the uniform dispersion effect of polyvinylpyrrolidone on CNTs and its complexation with Ni ions, a uniform coating of Ni nanoparticles on CNTs was successfully prepared through a hydrothermal process. The resulting Ni/CNTs composites exhibited excellent microwave absorption performance, making them valuable for developing novel microwave absorption materials.

Summary: Nickel nanoparticles are widely used in various industries, but their toxicity when orally ingested is not well understood. This study investigated the acute and subchronic oral toxicity of nickel nanoparticles in rats. It was found that the toxicity of nickel nanoparticles depended on the dosage, and they had effects on the brain and immune system. Compared to equivalent doses of soluble nickel salts, nickel nanoparticles may pose additional health risks.

Summary: This study demonstrated that Cu2O microparticles were rapidly dissolved to copper ions inside cells, followed by lysosome-mediated exocytosis. Smaller microparticles had a lower uptake rate but dissolved more quickly, leading to faster exocytosis activation. The rapid release of copper ions resulted in immediate toxic effects, mainly through necrosis, while glutathione buffering ability alleviated copper toxicity. The turnover of intracellular copper was much faster at sublethal exposure levels, but the labile copper(I) concentration only increased by a maximum of 2 times. Tolerance to copper-based nanoparticles depended on their ability to discharge released copper ions.

Summary: Copper-beryllium alloys are commonly used for thermoplastics injection molds due to their high thermal conductivity, but surface coatings are still needed for enhanced abrasion resistance, which can lead to over-aging. Using an electroless nickel-phosphorus coating with heat treatment can increase wear resistance, reduce wear coefficient, and maintain substrate hardness.
