Phosphotene nanoribbons (PNRs) are ribbon-like chains of the two-dimensional material phosphorus, similar to graphene, made up of atomic layers one atom thick.PNRs were first produced in 2019, and hundreds of theoretical studies have predict
DeepMind, the wunderkind of artificial intelligence research, has long been all about fun and games.The London-based group, part of Alphabet, Googles parent company, uses deep learning to train algorithms that can beat world champions of Go
Instead, tungsten is thought to be formed from the explosions of massive stars. Each supernova explosion has so much energy that these newly created elements are jettisoned at incredible speeds of 30,000 km/s, or 10% of the speed of light – and that's how they get dispersed throughout the universe. Because of that, tungsten cannot be cast, forged, or rolled like other metals but must be pressed into shape while in powder form and then sintered. It is frequently alloyed with other metals, such as
What is Boron Carbide? Boron carbide is also known by the name black diamond. It's an organic substance that has the formula B4C and which is often a grey-black powder. It is one the hardest materials known (after cubic boron Nitride and diamond) and it is used in body armor, tank armour and other industrial applications. Boron carbide has an Mohs hardness of about 9.5. Boron carbide does not react with any acid or alkali solution, so it is insoluble even in water. Boron carbide is also kno
There are abundant reserves of silicon. Si and Li can form a Li4.4Si structural arrangement, with a theoretical specific energy of 4200mAh/g. That is almost ten-times higher than that of the lithium-ion battery currently in use. In the present day, silicon materials are used in lithium-ion cells primarily for two reasons. One way is to add nano-silicon to anode materials to create a carbon-silicon anode. To improve the performance, organosilicon compounds can be added to the electrolyte. The Un
