Cornwall County and its surrounding areas in England have one of the largest tin-tungsten deposits in the world, but since the 1990s, mines that have been mined for centuries have been abandoned due to the collapse of metal prices, making them unable to survive.

A technique that introduces carbon-hydrogen molecules into a single atomic layer of the semiconducting material tungsten disulfide dramatically changes the electronic properties of the material, according to Penn State researchers at Penn State who say they can create new types of components for energy-efficient photoelectric devices and electronic circuits with this material.

A team of researchers led by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a simple method that could turn ordinary semiconducting materials into quantum machines—superthin devices marked by extraordinary electronic behavior. Such an advancement could help to revolutionize a number of industries aiming for energy-efficient electronic systems—and provide a platform for exotic new physics.

Scientists have uncovered some exotic quantum behavior of semiconductor materials that turn them into “quantum machines”.

Just imagine taking two extremely ultra-thin materials with different properties and placing one on top of the other, and obtaining a new material with hybrid properties.

Analysis of latest tungsten market from Chinatungsten Online

The ammonium metatungstate (APT) and tungsten powder prices maintained stability in the week began on Monday May 27 as the market outlook is still unclear in the short term. In the tungsten market, buyers’ expects for terminal demand, trading environment at home and abroad, solutions of inventories in Fanya Metal remain uncertain, and thus they are not active in stocking up. 

Rare earth market quotation in China: rare earth prices have gradually returned to stabilize when market mentality becomes more rational after the ban on imports from Myanmar and the visit of rare earth enterprises of central leaders. Insiders pointed out that domestic environmental protection inspections are not diminished, coupled with the rectification of the order of the rare earth industry, Myanmar's restrictions on exports, the supply is greatly reduced, and that would be a certain positive support for the industry. 

Molybdenum market quotation in China: the latest prices of molybdenum oxide, ammonium molybdate and ammonium heptamolvbdate are unchanged from the previous trading day. In the molybdenum concentrate market, the supply from mines is limited, so the availability of raw materials remains tight, coupled with stabilized offers from large tungsten companies, prices in the raw material side keep at a relatively high level. 

Thousands of miners scoured underground tunnels for cobalt in sunny and dusty areas of southern Congo. Many of them work by hand in the hope of earning a living from the meagre wages offered by the mining site. They are called "human diggers" (reported by American journalist Todd C. Frankel, Photography by Lena Mucha, a German journalist, translated by tungsten online).
