The dark electrocatalytic and light photocathodic hydrogen evolution properties of Ni, Ni–Mo alloys, and Pt on Si electrodes have been measured, to assess the viability of earth-abundant electrocatalysts for integrated, semiconductor coupled fuel formation. In the dark, the activities of these catalysts deposited on degenerately doped p-Si electrodes increased in the order Ni < Ni–Mo # Pt. Ni–M...

Concentrations of heavy metals (As, Co, Cu, Ni, Mo, Pb and Zn) are studied in the soil of Shiraz industrial complex zone, south Shiraz, Iran to asses metal contamination due to industrialization, urbanization and agricultural activity. Soil samples were collected from three different depths. The A and C depths are enriched with metals such as Ni, As, Mo, Cu, Pb and Zn, compared with the B depth...

The title complex, [Ni(II)(C(2)H(8)N(2))(3)](2)[Mo(IV)(CN)(8)]·2H(2)O, crystallized from a mixture of ethane-1,2-diamine (en), octa-cyano-molybdate(IV), [Mo(CN)(8)](4-), and the transition metal ion Ni(2+). In the crystal structure, the Mo polyhedron has a square-anti-prismatic shape, while the geometry around the Ni atom is distorted octa-hedral. The complex ions and water mol-ecules are linke...

The paper studies the influence of 0.5–1.8 wt.% Ni alloying on superplasticity, microstructural evolution, and dynamic grain growth effect in a temperature range 625–775 °C room mechanical properties two-phase Ti-Al-Mo-V alloys. Due to decrease β transus an enhancement alloy diffusivity, increase content significantly improved superplasticity. Ni-modified alloys exhibited 1.5–3-fold lower flow ...

Structures operating at high temperatures and exposed to aggressive gaseous media are made of low-alloy molybdenum TsM-10 of the system Mo-Al-B, TsM-6 of the system Mo-Zr-B and TsM-12 of the system Mo-Zr-Hf-B [1, 2]. Alloy TsM-10 is commercially pure molybdenum deoxidized by aluminium and boron. Alloy TsM-6 is alloyed with up to 0.2 wt. % zirconium and TsM-12, is alloyed with up to 0.03 wt. % z...

The passive corrosion properties of a series of Ni–Cr–Mo alloys were investigated. The alloys studied were C22, C2000, C276, C4 and 625. Potentiostatic experiments at potentials within the passive range were obtained as a function of temperature (25–85 ◦C) for each alloy. Each specimen was subsequently analyzed by time-of-flight secondary ion mass spectrometry (TOF SIMS) and X-ray photoelectron...

To investigate the irradiation properties of Mo-Re alloy of low Re content (atm%: 0% 8:4%), Mo-Re alloy films were irradiated by 200 keV xenon ions at the dose of 5 10 ions/cm. Different irradiation effects were observed on the samples of different Re content. While the sample of pure Mo remained the same after irradiation, obvious localized amorphization phenomenon took place in the sample wit...

A new Zn-Ni-Cd plating process was developed which offers a unique way of controlling and optimizing the Ni and Cd contents in the final deposit. Zinc-nickel-cadmium alloy was deposited from a 0.5 M NiSO4 1 0.2 M ZnSO4 bath in the presence of 0.015 M CdSO4 and 1 g/L nonyl phenyl polyethylene oxide. Using this process a Zn-Ni-Cd ternary alloy, with a higher nickel content as compared to that obt...

The surface chemistry and thickness of the native oxide, hydroxide, modified sub-surface layer three Ni superalloys (alloy 59, 625, 718) were determined by synchrotron X-ray Photoelectron Spectroscopy (XPS) Reflectivity (XRR). Taking advantage radiation techniques, a procedure for normalizing photoelectron intensity was employed, which allowed accurate quantitative analysis revealing total oxid...
