Published Control over friction, from small to large scales
(via sciencedaily.com) Original source Friction is hard to predict and control, especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces, even at large scales, is determined by the forming and rupturing of microscopic chemical bonds between them. This makes it possible to control the amount of friction using surface chemistry techniques.
Published 2D material reshapes 3D electronics for AI hardware
