Friction impacts motion, hence the need to control friction forces. Currently, this is accomplished by mechanistic means or lubrication, but experiments conducted by researchers at the Department of Energy’s Oak Ridge National Laboratory have uncovered a way of controlling friction on ionic surfaces at the nanoscale using electrical stimulation and ambient water vapor.

As thesis writing approached, University of Wisconsin-Madison graduate student Veronica Berns faced a conundrum. She knew how hard it was to describe her work to friends and family — indeed, anybody outside the tight clan of structural chemists. And that was particularly true since she concentrated on a category of should-be-impossible structures called “quasicrystals.”

University of Chicago scientists have experimentally observed for the first time a phenomenon in ultracold, three-atom molecules predicted by Russian theoretical physicist Vitaly Efimov in 1970.
