Micron-sized CoCrNi medium-entropy alloy (MEA) wires are successfully fabricated by Taylor-Ulitovsky method for the first time. The of two different sizes, with diameters 40 and 100 microns, exhibit an excellent combination tensile strength ductility. In-depth microstructure characterization indicates superior mechanical properties stem from synergy Lomer-Cottrell locks, nano-twinning HCP stack...

Tungsten trioxide (WO3) is always oxygen-deficient or non-stoichiometric under atmospheric conditions. Positively charged oxygen vacancies prefer to drift as well as electrons when the electric field is strong enough, which will alter the distribution of oxygen vacancies and then endow WO3 with memristive properties. In Au/WO3 nanowire/Au sandwich structures with two ohmic contacts, the axial d...

We describe a composite of the n-type semiconductors for the photoelectrochemical oxygen evolution reaction (OER). A simple drop-casting technique of mixed precursors and a one-step annealing process were used in the synthesis of the WO3/CuWO4 composite. The composite showed improved photocurrent for water oxidation compared to either of the two compounds individually. We discuss possible elect...

tungsten trioxide (wo3) films have been coated on indium thin oxide (ito) conductive glass substrate, using aqueous solution of peroxotungstic acid (pta) by the sol-gel dip coating method. x-ray diffractometery (xrd) analysis confirmed monoclinic and triclinic structure for the film and powdered wo3 respectively. fourier transforms infrared spectroscopy (ft-ir) exhibited the structure of peroxo...

We report the synthesis of nanostructured tungsten trioxide (WO3) films and their electrochromic characteristics. Plate-like monoclinic WO3 nanostructures were grown directly on fluorine-doped tin oxide glass substrates by a simple and low-cost crystal-seed-assisted hydrothermal method. The growth mechanism of the film is investigated. HRTEM analysis reveals the single crystalline quality of th...

Tungsten nano-oxides of WO3 and H2WO4 have been studied as promising candidates for photocatalytic chromic materials. To date, nanoparticles are generally prepared by hydrothermal synthesis, which requires high temperature environment pH adjustment. In this paper, we report on fabricating via photosynthesis UV irradiation the solution made from dissolving tungsten in hydrogen peroxide. Similarl...

The dielectric behavior of insulations is a key factor affecting the development anti-corona materials for generators. Epoxy resin (EP), as matrix, blended with inorganic fillers micron SiC and nano SiO2 to investigate effect micro doping on conductivity breakdown mechanism composites. Using experimental simulation analysis, it found that nano-SiO2 concentration related dispersion particles. lo...
