Friction is a key phenomenon in applied physics, whose origin has been studied for centuries. Until now, it has been understood that mechanical wear-resistance and fluid lubrication affect friction, ...
At large scales, water flows faster through a wider pipe than a narrower one. However, in tiny carbon nanotubes flow-rate is flipped, with water moving faster through the narrowest channels. This week ...
