Tungsten disulfide has a layered structure related to MoS2, with W atoms situated in trigonal prismatic coordination sphere. Owing to this layered structure, WS2 forms inorganic nanotube was discovered on an example of WS2 and has been the first material which is able to form it in 1992.  

Current operating computers and electronics are based on motion and energy states, with an operating speed of approximately 1 billion operations per second.  Typically, the rate at which these devices apply voltage depends on the number of transistors. The smaller the switch, the higher the clock frequency and the higher the performance of the computing system. But do you know that in the future, quantum computing will increase the existing limit speed by another 1 million times and achieve 1000 trillion operations per second.

Tungsten disulfide property is diamagnetic, lubricious and easy to be dissociative. It is a compound of tungsten and sulfur, chemical formula is WS2, molecular weight 247.97, the state is black gray powder, appears in the natural world as a tungstenite. The relative density is 7.510. It adopts a layered structure related to MoS2, with W atoms situated in trigonal prismatic coordination sphere. 

Recently, a team of scientists at the US Department of Energy's Princeton Plasma Physics Laboratory won the US Department of Energy Science Award, which resulted in the development of two new X-ray diagnostic instruments for the French West Tokamak project. This instrument can be used to diagnose the possible risk of melting of the first wall material of the plasma in the ITER artificial solar project.
