Sliding metals show fluidlike behavior, new clues to wear

(Phys.org)—Researchers have discovered a swirling fluidlike behavior in a solid piece of metal sliding over another, providing new insights into the mechanisms of wear and generation of machined surfaces that could help ...

Images capture split personality of dense suspensions

Stir lots of small particles into water, and the resulting thick mixture appears highly viscous. When this dense suspension slips through a nozzle and forms a droplet, however, its behavior momentarily reveals a decidedly ...
