Fall 2016 - Fall 2019. This award investigates the mechanics of how synthetic surfaces with micrometer-sized pillars adhere to and slide on soft and wet substrates. Micro-pillar arrays have been ...

Physicists have a pretty good idea of what to expect when friction and adhesion occur in the visible world. You jam on the brakes and your car stops. But how slippery or sticky are things that are too ...

Micro injection molding has become a cornerstone for mass-producing microfluidic devices, yet demolding defects and mold wear remain persistent challenges. This study introduces a nickel mold ...

As a simple theoretical model of a cell adhering to a biological interface, we consider a rigid cylinder moving in a viscous shear flow near a wall. Adhesion forces arise through intermolecular bonds ...

The proposed project will provide information on how surface structure and pressure distributions between surfaces and in confined films affect adhesion and friction at the nanoscopic level. This is ...

Philosophical Transactions: Mathematical, Physical and Engineering Sciences, Vol. 366, No. 1869, Nanotribology, Nanomechanics and Applications to Nanotechnology I (Apr. 28, 2008), pp. 1351-1381 (31 ...

In their exploration of smart materials with tunable friction, scientists have made interesting observations regarding the structure of materials. In experiments they found that friction forces are ...

Inspired by the hairs that allow geckos to hang single-toed from sheer walls and scamper along ceilings, a UC Berkeley-led team of researchers has created an array of synthetic micro-fibers that uses ...

Remora fishes are famed hitchhikers of the marine world, possessing high-powered suction disks on the back of their head for attaching themselves in torpedo-like fashion to larger hosts that can ...
