Dec. 1, 2023 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 ...
Sep. 22, 2022 Chemists and physicists shed light on a crucial aspect of friction: how things begin to slide. Using fluorescence microscopy and dedicated fluorescent molecules, they are able to pinpoint how and ...
Sep. 28, 2023 The friction on a graphene surface can be dynamically tuned using external electric fields, according to ...
July 25, 2022 For machines with mechanical elements, friction is an unavoidable enemy. It is a major source of service failure and can reduce the lifespan of any machinery, from bicycles and cars to airplanes and ...
Nov. 3, 2022 Chemists and engineers have discovered a fundamental friction law that is leading to a deeper understanding of energy dissipation in friction and the design of two-dimensional materials capable of ...
Mar. 3, 2023 Moving parts in mechanical come into regular contact, leading to wear and tear. Now, researchers have developed a contact control system, driven by artificial intelligence, to greatly reduce contact ...
Apr. 29, 2021 Although robotic devices are used in everything from assembly lines to medicine, engineers have a hard time accounting for the friction that occurs when those robots grip objects - particularly in ...
June 16, 2021 An international team has developed spherical colloidal particles for the visualization of rotational dynamics. The two-color fluorescent particles have an off-center core that allows tracking of ...
Dec. 15, 2022 In baseball, even the smallest detail can tip the scales in favor of the batter or the pitcher. A recent publication has highlighted how rosin powder helps maintain a more constant friction when ...
Jan. 11, 2023 A material state known as super-lubricity, where friction between two contacting surfaces nearly vanishes, is a phenomenon that materials researchers have studied for years due to the potential for ...
