This new form, tentatively attributed to a peroxo-like species, is also generated after the adsorption of oxygen on the nickel oxide sample deeply reduced by Ar+ bombarding, a fact that points to its stabilization on surface unsaturated nickel sites, produced in a high concentration by sputtering...
Solid oxide cells with nickel/yttrium-stabilized zirconia (Ni/YSZ) cermet electrodes exhibit Ni migration which can cause severe cell performance degradation. The experimentally reported migration behavior of Ni is complicated, and the mechanisms remain under debate. This work discusses the possible mecha...
Notably, foreign media reported yesterday that the Indonesian government is considering significantly reducing nickel ore mining quotas to support the market price of the metal. The Ministry of Energy and Mineral Resources is expected to lower next year's mining quota to 150 million mt, a...

SMM, December 4th: This week, the global nickel ore market remained generally stable, with slight differences in market performance between major producing countries, the Philippines and Indonesia, drawing widespread attention within the industry. In t
h0l, h00, 00 l: h = 2n and 0k0: k = 2n, suggesting the three possible space groups C2 (No. 5), Cm (No. 8) and C2/m (No. 12), however, the only possible space group C2/m (No. 12) is chosen by comparing all possible space groups of molybdenum nickel oxide....
Discover how EBSD can be used to obtain grain size and texture information from NCM (nickel, cobalt, manganese) cathode material. By characterising and comparing samples of different cathode materials at different stages of the battery’s lifetime, it's possible to link the performance with the ...
The oxidation state of nickel in the N200 sample is Ni2+. However, in samples N300 and N400, Ni3+ is also induced ranging from 854.87 to 855.26 eV and 862.22–863.66 eV, respectively. It has been observed that the concentration of Ni3+ ions increases with an increase in calcination ...
1c. We introduce a fast CWT event detection algorithm, that addresses these problems, using the example of single-peak detection. Parallel cluster wavelet analysis (PCWA) for single-peak detection Figure 2a shows a typical time-dependent signal for single-particle detection with the optofluidic ...
