Structure of nickel-iron and nickel-zinc electrodeposits
Electrodeposited nickel-iron and nickel-zinc alloys have been studied using `direct' methods e. g. XRD, microscopy, EDX and GDOES on coatings having different thicknesses and deposited on different substrates. The work has confirmed and extended the ideas of Finch et al. (2, 51), Piontelli et al. …

Synthesis And Characterization Of Nickel Complexes With Relevance To Nickel Acireductone Dioxygenase And Nickel Superoxide Dismutase
<p>This research presents an investigation of synthetic model complexes with relevance to the active site of Ni(II) acireductone dioxygenase (Ni-ARD) and Ni(II) superoxide dismutase (Ni-SOD). Acireductone dioxygenases (ARDs) are a unique set of enzymes found in the methionine salvage pathway that …

Neutron spectroscopic factors of Nickel-56 via Nickel(p,d)-56 Nickel-55 reaction in inverse kinematics
Transfer reactions have been the classic tool for studying the angular distributions, the excitation energies, and the spectroscopic factors of possible single-particles states. With the advent of radioactive beams, there has been a renewed effort to utilize these beams in transfer reactions in …

Heavy-ion damage in copper, nickel and dilute nickel alloys
Though it has long been appreciated that materials differ in their response to heavy-ion irradiation, the reasons for this are not yet fully understood. To more fully characterize the effects of material, alloying element, irradiation temperature and ion dose on the probability of collapse of a …

Control of electrodeposit properties of nickel and nickel alloy by pulse plating.
… Watts and Ni/Fe baths.The electro-depositions of nickel and nickel-iron alloy on copper and mild-steel substrates using Watts and Ni/Fe baths have been investigated. The mechanical properties of micro-hardness and internal stress obtained using the EFCO stress-meter and X-ray diffraction were …

Hydrogen Embrittlement of Nickel
… boundaries on intergranular fracture of charged nickel deformed in tension. Two modes of hydrogen segregation are investigated; lattice diffusion and dislocation transport of "Cottrell atmospheres" of hydrogen. The effect of cosegregation of hydrogen and sulfur is also explored.

Field emission from carbon nanotubes deposited on platinum and nickel/nickel oxide multilayers
… functions were fabricated from platinum and from nickel / nickel oxide. Nickel oxide was deposited by e-beam evaporation or grown by thermal oxidation and characterized by Auger electron spectroscopy, x-ray diffraction and ellipsometry. Carbon nanotubes were deposited onto these test structures …

Computational heterogeneous catalysis applied to steam methane reforming over nickel and nickel/silver catalysts
… direct combustion for electricity generation. Nickel is the preferred SMR catalyst; however, the efficiency of SMR over nickel can be severely hindered by carbon formation, which leads to the deactivation or even destruction of the catalyst particles. Thus, there is significant interest in …

Nickel laterites, origin and climate
Nickel laterites account for ?40 % of global nickel production and contain 60 % of the world's total land based nickel resources. Despite the importance of these deposits published studies, detailing their morphology and formation processes are relatively few and the interaction of variables …
