Recently, a new type of transistor with heterojunction of tungsten disulfide and graphene has been created by the research team of University of Groningen. Details of the research have been published in the October 16 issue of Physical Review B.

Tungsten disulfide is a kind of lubricating material with high quality. It can be used in automotive gear lubrication to speed up the heat dissipation and reduce the wear on the gear surface. The lubrication treatment with tungsten disulfide is usually simple, which make the material an ideal choice for the automotive gear lubrication.

Tungsten disulfide with good lubricating performance works stably under the condition of high temperature, high speed and heavy load, which is the working environment of crankshaft. Therefore, tungsten disulfide is an ideal material for crankshaft lubrication.

Tungsten disulfide has good high temperature and extreme pressure resistance, so it is suitable for the lubrication of automotive gear. Applied on the gear surface, tungsten disulfide can reduce the friction loss in the operation process and greatly prolong the gear’s service life.
