Water-repelling surfaces reveal surprising charging effects

Materials that repel water are used in countless applications, including industrial separation processes, routine laboratory pipetting, and medical devices. When water touches these surfaces, the interface where they meet ...

Electronic friction can be tuned and switched off

Researchers in China have isolated the effects of electronic friction, showing for the first time how the subtle drag force it imparts at sliding interfaces can be controlled. They demonstrate that it can be tuned by applying ...
