Machine parts wear, if there is friction between their metal surfaces. Lubricants and functional oils help prevent this. They attract dirt, debris and dust, and over time form lumps or become resinous. Machine parts then ...

(Phys.org)—A team of researchers working at Argonne National Laboratory, in Illinois, has found a way to dramatically reduce friction between two macroscopic scale surfaces—to near zero. In their paper published in the ...
Researchers have demonstrated a new process for the expanded use of lightweight aluminum in cars and trucks at the speed, scale, quality and consistency required by the auto industry. The process reduces production time and ...
