The current state of thin film heterojunction solar cells based on cuprous oxide (Cu₂O), cupric oxide (CuO) and copper (III) oxide (Cu₄O₃) is reviewed. These p-type semiconducting oxides prepared by Cu oxidation, sputtering or electrochemical deposition are non-toxic, sustainable photovoltaic materials with application potential for solar electricity. However, defects at the copper oxide hetero...

The increasing use of manufactured nanoparticles (NP) in different applications has triggered the need to understand their putative ecotoxicological effects in the environment. Copper oxide nanoparticles (CuO NP) are toxic, and induce oxidative stress and other pathophysiological conditions. The unique properties of NP can change depending on the characteristics of the media they are suspended ...

An aqueous extract of the shade-dried parts Asparagus aethiopicus L. and densiflorus (Kunth) Jessop was used to synthesize copper (CuO) nanoparticles (Cu NPs). UV-visible spectroscopy performed assess formation Cu NPs. Maximum absorbance obtained between 310–360 nm, confirming CuO NPs were effective against Pseudomonas aeruginosa (ATCC 27853), a gram-negative human pathogenic bacterium. The bac...

CuO nanoparticle was found to be an efficient catalyst for the synthesis of flavanones derivatives from the reactions between 2-hydroxyacetophenones and aromatic aldehydes at room temperature. The protocol offers advantages in terms of higher yields, short reaction times, and mild reaction conditions, with reusability of the catalyst. The structures of the synthesized substituted flavanones wer...

Abstract Background Disulfiram (DS), in the presence of copper (Cu), exhibited potent broad anticancer activity. However, its clinical application is limited due to poor solubility and stability. Hence, a novel nanocombination DS with bacterially synthesized oxide nanoparticles (CuO NPs) was prepared herein improve efficacy typical DS–Cu complex. Our design utilized nanocharacterization prooxid...

The main mechanism of toxicity for fast-dissolving nanoparticles (NPs) is relatively simple as it originates from the intrinsic toxicity of their constituent elements rather than complicated surface reactivity. However, there is little information about the compared toxicity of fast-dissolving NP and its constituent ion, which is essential for understanding the mechanism of NP toxicity and the ...

Three-dimensional (3D) porous ZnO-CuO hierarchical nanocomposites (HNCs) nonenzymatic glucose electrodes with different thicknesses were fabricated by coelectrospinning and compared with 3D mixed ZnO/CuO nanowires (NWs) and pure CuO NWs electrodes. The structural characterization revealed that the ZnO-CuO HNCs were composed of the ZnO and CuO mixed NWs trunk (~200 nm), whose outer surface was a...

Increasing in production and exposure to engineered nanoparticles (NPs), make necessary to acquire information about NP potential adverse health effects. Many studies, focused on NP toxicity, highlighted their cytotoxic potential but there is still a lack of information about the biological mechanisms involved. The aim of this research is the comparison of cytotoxicity between two types of meta...

Nanocomposites based on anodic titanium oxide nanotubes with copper nanoparticles were formed and their structural, optical, electrophysical properties studied. Defects in the structure of samples identified by electron paramagnetic resonance it was shown that, as a result deposition, CuO surface nanotubes. It found that conductivity decreases several orders magnitude an increase number deposit...
