Blowing bubbles on a nanoscale

(PhysOrg.com) -- Scientists are puzzled by the nanobubbles that can develop on surfaces under water. It should be impossible for them to exist but nevertheless they remain intact for hours. They are something of a mystery, yet it is possible to manipulate the development of these bubbles, according to PhD candidate Shangjiong Yang at the University of Twente, Netherlands. The bubbles can then, for example, be used to reduce flow resistance in liquids. Yang received his doctorate from the Faculty of Applied Sciences on 9 October.
