The production of hydrogen (H2) through photoelectrochemical water splitting (PEC-WS) using renewable energy sources, particularly solar light, has been considered a promising solution for global and environmental challenges. In the field hydrogen-scarce regions, metal oxide semiconductors have extensively researched as photocathodes. For UV-visible light-driven PEC-WS, cupric (CuO) emerged sui...

A new amino-cupric silver protocol is described for detection of neuronal degeneration. We describe its selectivity in visualizing both early and semiacute degeneration after intracerebral or systemic administration of a variety of neurotoxicants in rats, and after transient ischemic episodes in gerbils. As early as 5 min after physical trauma, or 15 min following either intrastriatal injection...

1. The musculotropic activity of eledosin on the isolated guinea-pig ileum is antagonized by morin, a flavonoid derivative.2. The anti-eledoisin activity of morin is abolished by fresh rat plasma and by deproteinized rat plasma, but not by deionized plasma.3. Cupric acetate can restore the inhibitory property of the deionized plasma and can also inactivate morin.4. This effect of rat plasma and...

Studies of the chemical properties of the enzyme, catecholase, have shown that this polyphenoloxidase consists of a copper-protein complex (l-3). Indications have also been obtained that the enzymic activity of catecholase is associated with the copper part of the molecule, since it has been found that the addition of certain reagents known to react with cupric ions will inhibit the enzymic act...

Evidence is presented here that cupric ions play a part in the natural spinning of Bombyx mori silk. Proton induced X-ray emission studies revealed that the copper content increased from the posterior part to the anterior part of silk gland, and then further increased in the silk fiber. Spectrophotometric analysis demonstrated that cupric ions formed coordination complexes with silk fibroin cha...

Cupric oxide (CuO) has been used as a non-enzymatic glucose sensor for decades. However, there is paucity of publications on bare CuO-based photo electrochemical (PEC) detection. In this study, active CuO thin film was electrodeposited onto conductive glass and its band gap tuned by etching in NH3 solution. A 6 W light-emitting diode (LED) bulb the light source PEC oxidation. Various physical c...

Highly sensitive gas detecting devices are of significant importance in various applications such as environmental air quality monitoring or occupational safety and health. In the last decades considerable advances have been made in the development of conductometric metal oxide gas sensors and in optimization of sensor performance regarding sensitivity and selectivity. Traditional metal oxide b...

Abstract Cupric oxide (CuO), as a transition metal (TMO) semiconductor, has attracted tremendous attention for various applications. In the present work, we synthesize CuO nanosheets modified by TiO 2 nanoparticles via facile, non-toxic two-step method. Subsequently, morphology and structures of /CuO nanocomposites are investigated. By utilizing common Z-scan technology, broadband nonlinear opt...
