Abstract An approach to fabricate double-sided, high-current RE-Ba2Cu3O7-δ(REBCO) tapes for use in ultrahigh-field superconducting magnets operating at and above 20 T is demonstrated. In this work, we modified our advanced metal organic chemical vapor deposition (A-MOCVD) reactor deposit REBCO films on each side of a double-sided buffer substrate single pass. The composition, thickness critical...

Strained InGaAS/AIGaAS quantum well (QW) lasers operating at 0.98 jim are currently of great interest due to their suitability for pumping erbium-doped fiber amplifiers. They are reported to yield a lower noise figure and higher gain coefficient than the 1 .48 jim InGaAsflnP pump lasers as well as 0.8 p.m A1GaAS/GaAS pump lasers. In addition, the InGa.AS/AIGaAS strained QW lasers have lower thr...

Abstract Photoelectrodes capable of cost-effective hydrogen production on a large scale, via photoelectrochemical water splitting under solar light, could offer an elegant solution to many current problems humankind caused by over-reliance fossil fuels and the resulting environmental pollution. The search design low-cost photoelectrode materials substrates for practical applications are require...

The aim of this study was to evaluate the efficacy of low-level 940 nm laser therapy with energy intensities of 5, 10 and 20 J/cm2 on bone healing in an animal model. A total of 48 female adult Wistar rats underwent surgery to create bone defects in the right tibias. Low-level laser therapy (LLLT) was applied immediately after surgery and on post-operative days 2, 4, 6, 8, 10 and 12 in three st...

For the first time, the TiO2 nanorod arrays have been prepared on ITO substrates at room temperature by dc reactive magnetron sputtering technique. These TiO2 nanorods have a preferred orientation along the (220) direction and are perpendicular to the ITO substrate. Both the X-ray diffraction and Raman scattering measurements show that the highly ordered TiO2 nanorod arrays have an anatase crys...

Ordered ZnO nanosheet arrays were grown on weaved titanium wires by a low-temperature hydrothermal method. CdS nanoparticles were deposited onto the ZnO nanosheet arrays using the successive ionic layer adsorption and reaction method to make a photoanode. Nanoparticle-sensitized solar cells were assembled using these CdS/ZnO nanostructured photoanodes, and their photovoltaic performance was stu...

In this paper, in order to improve the efficiency of dye-sensitized solar cells, we introduced zirconia [ZrO2] nanofibers into a mesoporous titania [TiO2] photoelectrode. The photoelectrode consists of a few weight percent of ZrO2 nanofibers and a mesoporous TiO2 powder. The mixed ZrO2 nanofibers and the mesoporous TiO2 powder possessed a larger surface area than the corresponding mesoporous Ti...
