A dense molybdenum oxide layer was fabried on nickel foam (MoO 2 @Ni) and used as the hode in the 1-ethly-3-methylimidazolium chloride/AlCl 3 ionic liquid electrolyte aluminum ion battery. Study on the electrochemical performance demonstrated that the hode could not only exhibit a discharge potential of 1.9 V which is higher than most of the studied metal oxide hodes of Al ion

2017-4-7 · Besides, industrial grade hydrogen peroxide costs $390-500 per ton. One of the means to overcome this problem is the in-situ production of hydrogen peroxide. In this paper, a detailed review was conducted on the generation methods, degradation potential and optimum operating parameters for in-situ production of hydrogen peroxide/hydroxyl radicals.

A Lab-Grown Diamond Is Forever | Hacker News

Thus, the existing synthetic diamond infrastructre cant be used to make npd. The largest npd pieces reported in the literature are 15 x 15 mm cylinders, and they required a 6000 ton press. I don''t want soccer-ball sized npd, just npd big enough, (as well as cheap and readily available) to make typically-sized anvils for high pressure apparatus.
