Magnetically induced ferroelectric multiferroics present an exciting new paradigm in the design of multifunctional materials, by intimately coupling magnetic and polar order. Magnetoelectricity creates a novel quasiparticle excitation--the electromagnon--at terahertz frequencies, with spectral signatures that unveil important spin interactions. To date, electromagnons have been discovered at lo...

Highly efficient tree branch-shaped CuO photocathodes are fabricated using the hybrid microwave annealing process with a silicon susceptor within 10 minutes. The unique hierarchical, one-dimensional structure provides more facile charge transport, larger surface areas, and increased crystallinity and crystal ordering with less defects compared to irregular-shaped CuO prepared by conventional th...

At cryogenic temperatures thermoset polymers suffer from low fracture toughness. Herein, we present a strengthening and toughening technique for applications using cupric oxide (CuO) nanorods. These nanorods are synthesized via hydrothermal reaction to give an average length of 1.64 ? m diameter 270 nm. They exhibit coefficient thermal expansion (CTE) at temperatures, due the magnetostriction e...

The Cupric oxide (CuO) nanostructures and Fe doped CuO nanomaterials are synthesized by microwave irradiation method. effect of doping on the crystal structure, band gap optical properties samples were characterized using x-ray diffraction, ultraviolet-visible spectrometer, photoluminescence spectrometer Fourier transform infrared spectrometer. X-ray diffraction study confirms size particle in ...

In this paper, we present two approaches to synthesize nanostructured metal oxide semiconductors in a form of multi-layer thin films later assembled as conductometric gas-sensors. The first approach produces combination solid film tungsten trioxide (WO3) with nanoclusters cupric (CuO) prepared by magnetron-based gas aggregation cluster source (GAS). second method is two-step reactive magnetron ...

Male commercial broiler strain chickens were fed either a control diet (based on corn and soybean meal) or the control diet supplemented with cupric sulfate pentahydrate or cupric citrate in seven experiments (six in floor pens, one in wire-floored batteries). In Experiment 1, feeding 125 or 250 mg/kg copper increased growth (4.9%) and decreased feed conversion ratios (3.4%), total plasma chole...
