The objectives of the present study were to develop an environmentally friendly, low-price, easy, and fast method for developing antipathogenic (antibacterial, antifungal, antiviral) cuprous-oxide-coated multifunctional fabrics. fabrics first sensitized with citric acid, then Cu2O particles formed using Fehling solution method. cuprous oxide applied cotton To create particles, three different k...

The solubility of cupric and cuprous oxides was measured in water over the range 25 to 350 °C in the presence of various chemical agents (NaOH, NH3, B(OH)3, H3PO4, (OHCH2)3CNH2, (OHCH2)3CN(OHCH2CH3)2, HF3CSO3, HNO3 and mixtures thereof), and in steam to 400 °C as a function of pressure. Large discrepancies exist between the various experimental studies, especially at high temperatures for cupro...

The existence of uncertainties in the tables employed in the determination of lactose, alone and in the presence of sucrose, by the method of Munson and Walker has led to the redetermination of the reducing-sugar values from which these tables were calculated. The original tables were based on the weights of cuprous oxide corresponding to various weights of lactose, and in the present paper all...

We report herein the size-controlled preparation of monodispersed cuprous oxide octahedron nanocrystals smaller than 100 nm. The method is based on the reduction of copper nitrate in Triton X-100 water-in-oil (w/o) microemulsions by gamma-irradiation. The average edge length of the octahedron-shaped nanocrystals varies from 45 to 95 nm as a function of the dose rate. The quantum confinement eff...

We demonstrate a template-free synthetic approach for the preparation of a highly conductive Cu/Cu(2)O nanocomposite electrode by a chemical reduction process. Cu(2)O octahedra were prepared through chemical dehydrogenation of as-synthesized Cu(OH)(2) nanowire precursors. To provide a sufficiently electron-conducting network, the Cu(2)O particles were transformed into Cu/Cu(2)O nanocomposites b...

Metal-semiconductor hybrid heteronanostructures may exhibit synergistically reinforced optical responses and significantly enhanced optical tunability that essentially arise from the unique nanoscale interactions between the metal and semiconductor components. Elaboration of multi-component hybrid nanoparticles allows us to achieve optimized or diversified material functionalities through preci...

The efficiency of third-harmonic generation in cuprous oxide was measured. Intensities followed a noncubic power law that indicates nonperturbative behavior. Polarization anisotropy of the harmonic generation was demonstrated and related to the third-order susceptibility. The results will influence the understanding of harmonic generation in centrosymmetric materials and are potentially relevan...
