Probably everyone is familiar with the phenomenon: water drops cling to a pane of glass, if it is tilted out of the horizontal plane. Only when a certain angle is reached they slide off. This raises ...

(Nanowerk News) Working together to study friction on the atomic scale, researchers at UC Merced and the University of Pennsylvania have conducted the first atomic-scale experiments and simulations of ...

Controlling the friction between two moving surfaces — and possibly even reducing it to zero — is one of the outstanding challenges in modern tribology. Two recent discoveries may make this dream come ...

“Dragging” ultracold ions across an optical lattice has provided important insights into friction. By tweaking the distance between the ions, Alexei Bylinskii, Dorian Gangloff and Vladan Vuletić of ...
