Understanding and Controlling the Degradation of Nickel-rich Lithium-ion Layered Cathodes
… demanding more energy from batteries. Nickel-rich layered LiNi<sub>1-x-y</sub>Mn<sub>x</sub>Co<sub>y</sub>O₂ (1-x-y ≥ 0.6, NMC) cathodes could potentially provide the necessary energy to meet the demand of the high energy applications. Overcoming the stability issues from oxygen …

Investigating proteomic profiles of skin mucus and blood plasma of rainbow trout (Oncorhynchus mykiss) exposed to low concentrations of waterborne nickel
… of Fire located in the James Bay Lowlands is a nickel rich ore with ongoing mining proposals. This raises the possibility of nickel contamination in one of Ontario’s most precious freshwater regions and peatlands. However, impacts of nickel exposure on freshwater fish species remain elusive. To …

The suitability of Ni-Co catalysts in the dry reforming reaction
… This has led to nonnoble metals such as nickel and cobalt being considered as potential catalysts. Bimetallic nickel-cobalt (Ni-Co) catalysts have garnered a lot of interest as dry reforming catalysts as combining these two metals is believed to produce catalysts that would be more stable …

Characterisation of putative metal transport proteins in the nickel hyperaccumulator Senecio coronatus: investigating candidate genes for nickel tolerance and accumulation
… is known about the molecular mechanisms behind nickel accumulation. This is despite the fact that nickel hyperaccumulators constitute more than 75% of all known hyperaccumulator species. One such species is Senecio coronatus (Asteraceae), which is a useful model to study nickel hyperaccumulation …

Degradation Mechanisms and Applications in Ion Intercalation Materials
… degradation at a single particle scale, using nickel rich materials as an example, then projects single particle degradation into population scale for both solid solution and phase separating materials. Furthermore, I analyze and design improved pulse diagnostics using hybrid pulse power …

Nickel and cobalt sulfide nanomaterials for magnetic and energy applications
… namely bis(piperidinylldithiocarbamato)nickel(II) (1), bis(tetrahydroquinolinyldithiocarbamato)nickel(II) (2), bis(N’-ethyl-N-piperazinyldithiocarbamato)nickel(II) (3), tris(morpholinodithiocarbamato)cobalt(III) (4) and tris(N’-ethyl-N-piperazinyldithiocarbamato)cobalt(III) (5). These …

Relationships between homogeneity, structure and mechanical properties in certain sintered iron, nickel, carbon materials.
… classes of sintered material, each containing 3% nickel and 0.337% 0.03% carbon but with different initial degrees of homogeneity. This was achieved by the use of blended elemental powders, a nickel-plated iron powder produced in a specially developed apparatus and a prealloyed powder. Electron …

Carbon deposition on transition metal- and uranium-oxides
… in carbon deposition with changing composition. Nickel rich spinels were unstable in the reaction gas mixture and generated metallic nickel during exposure. At both temperatures, this gave levels of carbon deposition which increased with increasing nickel content of the original oxide. NiF~04 …

A Nuclear Magnetic Resonance Approach Towards Understanding Surface Modification and its Influence on Ni-rich Layered Oxides in Li-ion Batteries
… transitioning towards a carbon neutral society. Nickel-rich layered oxides are the state-of-the-art material of choice, offering high practical capacities. However, accessing this high capacity induces structural degradation and parasitic electrolyte reactions at the surface. One strategy to …

Stress Effects on Phase Morphological and Compositional Non-uniformity in Intercalation Compounds
… shows that the misfit strain between solute-rich and solute-poor phases could cause the flat interface between them to become unstable and develop non-planar morphology during interface- and diffusion-limited intercalation processes, which is analogous to the well-known Asaro-Tiller-Grinfeld …

Geology, mineralogy and geochemistry of the Cerro Matoso nickeliferous laterite, Córdoba, Colombia
The Cerro Matoso nickeliferous laterite, located in northern Colombia near the town of Montelibano, was developed in pre-Late Cretaceous ultramafic rocks consisting principally of slightly serpentinized harzburgite. The peridotite body is flanked by ferruginous sandy sediments with interbedded coal …
