NiWO(4) nanoparticles have been facilely synthesized by a hydrothermal approach, and used as a catalyst for the hydrodesulfurization of thiophene and its derivative 4,6-dimethyldibenzothiophene, showing a significantly higher activity than commercial NiW/Al(2)O(3).

The NIW (non-interaction of waves) property has been proposed by one of the coauthors. The NIW property states that in the absence of any “obstructing” detectors, all the Huygens-Fresnel secondary wave lets will continue to propagate unhindered and without interacting (interfering) with each other. Since a coherent lidar system incorporates complex behaviors of optical components with different...

Copyright©The Oceanographic Society of Japan/TERRAPUB/Springer Alford, 2003). Therefore, a study of the NIW energy transfer from the surface to the deep ocean around these western boundary current regions should consider the effect of strong background shear. Several studies have focused on how the background circulation affects the NIW propagation. Kunze (1985)’s theoretical treatment suggests...

In this paper NiW/γ-Al2O3catalysts were prepared by consecutive impregnation of a W/γ-Al2O3 catalyst with an aqueous solution nickel salt. The structural control the ion precursor in was achieved addition 1, 2-cyclohexanediamine-N, N, N’, N’-tetraacetic acid (CyDTA) as chelating agent at different pH. influence sulfidation pressure (1 bar vs 40 bar) on activity and structure NiW catalysts inves...

The Al, Zr, and Ti modified MCM-41 materials were prepared by the post-synthesis method, and then the Ni-W species were introduced on them by using the co-impregnation method in order to obtain high-performance hydrodenitrogenation (HDN) catalysts. The activity of the catalysts was evaluated by the HDN reaction of quinoline. The optimum HDN activity was observed on the catalyst sup...

Chemical deposition methods like MOD and MOCVD are promising approaches for coated conductors (CCs) due to their reduced cost and easy scaling. High quality La2Zr2O7 (LZO) buffer layers were prepared by MOD on Ni-5%at.W (NiW) RABiTS and subsequent YBCO layers (450 to 800 nm thick) were deposited by pulsed injection MOCVD, leading to a simple low cost architecture NiWRABiTS/LZOMOD/YBCOMOCVD. In ...

Crack-free and uniform nickel–tungsten (NiW) coatings their composite filled with ceramic particles such as silicon carbide (SiC) hexagonal-boron nitride (hBN) were deposited on brass substrates by applying direct current (DC) waveforms. Among all coatings, NiW–SiC–hBN displayed the noblest corrosion potential (−0.49 V) lowest density (4.36 × 10−6 A·cm−2). It also seems that addition of hBN SiC...

The structure of electrolytically deposited nanocrystalline alloys of the CoW-CoNiW-NiW systems under low-temperature heating was investigated by means of high-resolution transmission electron microscopy (HRTEM), high-angle annular dark-field scanning transmission electron microscopy (HAADF STEM), and analytical methods such as energy dispersive x-ray spectroscopy (EDS) and electron energy loss...

Investigations of the plastic deformation mechanisms Ni-W-based heavy alloys varying with increasing temperatures are very important for development hot forming processes and applications at elevated temperatures. In this study, continuous variation strength plasticity a novel alloy was investigated. The tensile Ni48W35Co17 sample 600 °C 471 MPa, which 47% lower than that 100 °C. A in an abnorm...
