The hexaethylcyclohexaarsoxane complexes [{M(CO)3}2{c>’c/o-(C2H 5A sO)6}], M = Cr, Mo, W, 2 4 have been prepared by the reaction o f (C2H 5AsO)n with the respective metal hexacarbonyl in toluene and characterized by their IR and NM R spectroscopic data. For 2 the molec­ ular structure was established by X-ray structural analysis. The 12 atoms o f the As60 6 ring form a flattened cuboctahedron i...

We investigated curvature-enhanced spin-orbit coupling (SOC) and spinterface effect in carbon-based organic spin valves (OSVs) using buckyball C60 and C70 molecules. Since the naturally abundant (12)C has spinless nuclear, the materials have negligible hyperfine interaction (HFI) and the same intrinsic SOC, but different curvature SOC due to their distinct curvatures. We fitted the thickness de...

Abstract Photocatalytic water splitting system using particulate semiconductor materials is a promising strategy for converting solar energy into hydrogen and oxygen. In particular, visible-light-driven ‘Z-scheme’ printable photocatalyst sheets are cost-effective scalable. However, little known about the fundamental photophysical processes, which key to explaining promoting photoactivity. Here,...

Boron-doped molybdenum silicides have been already recognized as attractive candidates for space and ground ultra-high-temperature applications far beyond limits of state-of-the-art nickel-based superalloys. In this work, we are exploring a new method fabricating Mo–Si–B alloys (as coatings or small bulk components) by utilizing pressure-less reactive melt infiltration approach. The basic assum...

TiO2-based photocatalyst materials have been widely studied for the abatement of contaminants emerging concerns (CECs) in water sources. In this study, 1.5 wt% Mo-doped HRTiO2 was obtained by sonochemical method. The material analyzed and characterized thermal, structural/textural, morphological, optical properties using TGA-DSC, XRD, TEM, FTIR, XPS, SEM-EDS, BET (N2 adsorption-desorption measu...

Co/N-mC composite presented ability MO (178 mg g −1 ) > RhB (141 (T = 25 °C, pH 7.0, C 0 20 ...

Ni-doped Mo carbide with Ni/Mo atomic ratio of 0.1 was supported on SiO2, Al2O3, and a porous carbon material (C), using combination gel combustion impregnation methods. XRD, XPS, XANES, EXAFS analyses indicated that the main active sites for catalysts were metallic nickel carbides. The evaluated in furfural hydrogenation to produce 2-methylfuran (2-MF) batch reactor at 150 °C under hydrogen pr...

Doped transition-metal dichalcogenides monolayers exhibit exciting magnetic properties for the benefit of two-dimensional spintronic devices. Using density functional theory (DFT) incorporating Hubbard-type correction (DFT$+U$) to account electronic correlation, we study magnetocrystalline anisotropy energy (MAE) characterizing Mn-doped MS$_2$ (M=Mo, W) monolayers. A single isolated Mn dopant e...

X-ray photoelectron spectroscopy (XPS) technique was employed to characterize Al2O3-TiO2 support and MoO3/Al2O3TiO2 catalyst calcined at different temperatures from 773 to 1073 K. The Al2O3-TiO2 (1:1.3 mole ratio) binary oxide support was obtained by a coprecipitation procedure with in situ generated ammonium hydroxide. A nominal 12 wt.% MoO3 was impregnated over the calcined (773 K) support by...
