Spontaneous Combustion in Nanobubbles Inspires Compact Ultrasonic Loudspeaker, University of Twente Study

Published: Sep 29, 2011

Nanometre-sized bubbles containing the gases hydrogen and oxygen can apparently combust spontaneously, although nothing happens in larger bubbles. For the first time, researchers at the University of Twente's MESA+ Institute for Nanotechnology have demonstrated this spontaneous combustion in a publication in Physical Review E. They intend to use the phenomenon to construct a compact ultrasonic loudspeaker.
