The invention relates to a lubricant which contains solid particles that are dispersed in an organic matrix and have a mean particle size of between 1 and 500 nm. The lubricant preferably contains between 0.05 and 30 % by weight, in relation to the total formulation, of solid particles. The...
Why are electrons, rather than protons, the principal charge carries in a metal wire? Why do photons have different masses? Discuss why equal masses of carbon atoms and oxygen atoms don't contain the same number of particles? Explain why a building made of bricks has smaller entro...
However, the use of a metal target can result in the evaporation of undesirable debris, such as small particles, atoms and ions, from the surface of the target, which debris may be deposited on sensitive optical components used to focus the beam on the target. The use of metal targets ...
