Rare earth market quotation in China: domestic rare earth price poorly performs in the short term amid the latest price of terbium oxide, europium oxide and praseodymium neodymium metal falls sharply, because the mentality of traders is greatly affected by the decline in listing prices of most enterprises. At the same time, the current market trend is expected to continue in the short term.

This is a mixed monolayer metal two-dimensional nano material. Scientists first used ultra-thin nano titanium dioxide, titanium dioxide is a common photocatalyst material, in titanium dioxide engraving nanopore, form a carrier. And then use the two tungsten sulfide (MO) nano film, two tungsten sulfide and molybdenum disulfide is a single-layer semiconductor transition metal materials has attracted much attention in recent years, due to the direct band gap semiconductors, high quantum yield, and has a significant effect on the valley polarization, optoelectronic applications has better effect than graphene.

Molybdenum market quotation in China: the latest price of molybdenum powder declined slightly while molybdenum bar and ferro molybdenum maintained stability. The price movements are mainly owing to poor performance in terminal market.

How to extract fuel from water? Now a technology is known for electrolysis of water reverse reaction, hydrogen and oxygen are supplied to the cathode and the anode, cathode and hydrogen diffusion through the reaction of the electrolyte, releasing electrons through the external load to the anode, the principle of this technique is widely used in hydrogen fuel cell.
