Electrode materials for calcium batteries: Future directions and perspectives
EcoEnergy, Volume 2, Issue 3, Page 339-368, September 2024.This Perspective primarily focuses on the advancement of positive electrode (cathode) materials for rechargeable calcium batteries and emphasises the potential of solid‐state metathesis routes in designing a wide range of high‐performance electrode materials. Abstract Despite the prevailing dominance of lithium‐ion batteries in consumer electronics and

Studies on Carrier Magnetic Separation of Fine Wolframite [PDF]
Carrier magnetic separation of fine wolframite (-5!1 m) was investigated using coarse magnetite (37~53!1m, etc.) as carriers and sodium oleate as a surfactant by high gradient magnetic separator. Effects of some factors on the carrier magnetic separation

Interaction of punches on orthotropic half-space
Advanced Engineering Research, 2016 An integral equation of the three-dimensional contact problem for an orthotropic half-space (9 independent elastic parameters in Hooke’s law) is obtained where its kernel does not include integrals, but it depends on the solution of a characteristic ...

Niobian wolframite from Glen Gairn, Eastern Highlands of Scotland: a microprobe investigation
, 1989 Electron microprobe data are presented from zoned niobian wolframite crystals in a quartz-wolframite-(cassiterite) vein and wall-rock from a zinnwaldite-bearing granite pluton that forms part of the late-Caledonian Glen Gairn granitic complex in the ...

Crystal Chemistry of Wulfenite (PbMoO4) and Wolframite ([Fe,Mn]WO4)
, 2021 This study examines the crystal chemistry of some natural simple molybdate and tungstate minerals, namely wulfenite (PbMoO4) and wolframite ([Fe,Mn]WO4). Historically, these mineral species have been a challenge to analyze through X-ray diffraction (XRD)

Unsupported sulfides obtained from high specific area mixed oxides as hydrotreating catalysts
Revista Facultad de Ingeniería Universidad de Antioquia, 2013 Several bimetallic Ni-Mo, Co-Mo and Co-W materials were prepared by co-precipitation and a Ni-W material through hydrothermal synthesis. The characterization by X-ray diffraction (XRD) of molybdates confirmed the formation of layered fy phase, while the

Geochemical wolframite fingerprinting - the likelihood ratio approach for laser ablation ICP-MS data [PDF]
, 2018 Wolframite has been specified as a ‘conflict mineral’ by a U.S. Government Act, which obliges companies that use these minerals to report their origin. Minerals originating from conflict regions in the Democratic Republic of the Congo shall be excluded ...
