The effects of Cr and Ni on three different types steel with carbon ratios under constant conditions such as the welding current 120A, voltage 80V, Diameter 10 mm angle 60 degree was observed. Nickel percentage up to 0.147% Chromium 0.083% contributed affecting mechanical properties steel. Undissolved carbide particles refine austenite grain size. In presence nickel, chromium is less effective ...

The influence of adding manganese to an Al2O3 support for preparing NiMo catalysts the hydroconversion soybean oil was herein evaluated. Two different Mn contents (1 and 5 mol % Mn) were used while Al2O3-Mnx (x = 1 or obtained by sol-gel method. wetness co-impregnation nickel molybdenum precursors onto as-formed supports considering two pH impregnation (5 9). Solids then characterized at oxide ...

Copper (Cu) and stainless steel 316 L are widely used for biomedical applications, such as intrauterine devices orthopedic/dental implants. Amino acids abundantly present in biological environments. We investigated the influence of select amino on corrosion Cu under naturally aerated deaerated conditions using a phosphate-free buffer. increased both aeration at pH 7.4. release was also signific...

Abstract Five different unsupported transition metal phosphides were synthesized and tested for hydrodeoxygenation of phenol in gas phase at 300 °C atmospheric pressure. The phosphide phases two steps: synthesis phosphates temperature programmed reduction. In situ X-ray diffraction reduction revealed the formation phases: Ni2P, MoP, CoP/CoP2, FeP WP. diffractograms showed that phosphate precurs...

Silica core-shell nanoparticles of about 60-120 nm with a closed outer layer of bismuth or molybdenum oxide of 1-10 nm were synthesized by an integrated chemical vapor synthesis/chemical vapor deposition process at atmospheric pressure. Film growth rates and activation energies were derived from transmission electron microscopy (TEM) images for a deposition process based on molybdenum hexacarbo...

Efficient total syntheses of fluvibactin and vibriobactin have been achieved via molybdenum(VI) oxide-catalyzed dehydrative cyclization, Sb(OEt)(3)-catalyzed ester-amide transformation, and WSCI and HOAt-promoted dehydrative amide formation.

Herein, we demonstrate a facile approach to synthesize long nickel nanowires and discuss its suitability to replace our commonly used transparent electrode, indium-tin-oxide (ITO), by a hydrazine hydrate reduction method where nickel ions are reduced to nickel atoms in an alkaline solution. The highly purified nickel nanowires show high transparency within the visible region, although the sheet...

Efficient oxygen-evolution reaction catalysts are required for the cost-effective generation of solar fuels. Metal selenides have been reported as promising oxygen-evolution catalysts; however, their active forms are yet to be elucidated. Here we show that a representative selenide catalyst, nickel selenide, is entirely converted into nickel hydroxide under oxygen-evolution conditions. This res...
