Abstract:

AbstractCopper (Cu) is a vital trace element involved in various physiological and biochemical processes. However, animals can only absorb a small fraction of Cu and the most is excreted, contaminating soil and aquatic environment. Hence, the use of this mineral as a growth promoter is today one of the crucial health and environmental concerns. In recent years, many studies have reported Cu nanoparticles (Cu-NP) as a promising alternative to antibacterial reagents and a growth promoter. Depending on the size, shape, dose and animal species, Cu-NP exhibit a variety of effects on animal performa

The use of nanomaterials in solar cooling applications has gained significant attention in recent years. This study aimed to increase thermal conductivity by depositing copper nanoparticles (Cu-NP) on low-carbon steel using thermal evaporation and a physical vapor deposition (PVD) method. Low-carbon steel was selected as the substrate due to its wide use in thermal applications and strong absorption properties.

Copper nanoparticle (Cu NP) is a promising replacement for noble metal nanoparticles due to its high electrical conductivity and low cost.

Gold electrocatalysts selectively convert CO2 into CO, which can be further processed into a wide range of other commodity chemicals, industrial precursors, and fuel additives.

Abstract:

In this work, copper nanoparticles (CuNPs) loaded cellulose acetate microfibers (CAMFs-Cu) are successfully prepared as a novel heterogenous catalyst. For this purpose, the cellulose acetate microfibers (CAMFs) with a diameter of ca. 300–500 nm are fabricated by electrospinning method. Then, CuNPs are deposited onto the CAMFs via a convenient wet reduction process using copper chloride as precursor and sodium borohydride as reduction agent. The chemical composition of the fabricated CAMFs-Cu is characterized by energy dispersive X-ray (EDX) spectroscopy, powder X-ray diffraction (XRD) and X-ra

Metal-based nanoparticles (NPs) can release metal ions that are toxic to aquatic organisms; however, whether the toxicity is from metal ions rather than unique “nano-scale” effects of the NPs is unresolved. The present study aimed to compare the toxicity of Cu2+ and Cu-NPs in larval zebrafish ( Danio rerio) to clarify whether toxic effects are attributable to release of Cu ions and to determine the effect of the chelating agent ethylenediaminetetraacetic acid (EDTA) and calcium hardness (as CaCO3) on the Cu toxicity.
