NASA captures unprecedented images of supersonic shockwaves

NASA has captured unprecedented photos of the interaction of shockwaves from two supersonic aircraft, part of its research into developing planes that can fly faster than sound without thunderous "sonic booms".

Hot nanoparticles produce giant and explosive bubbles

When gold nano particles in water are illuminated by a laser, they get very hot: well above the boiling point of water. The formation of vapour bubbles caused by this, is well-known. New experiments, however, using a very ...

Low pressure reduces bubble trouble

Spray coating and inkjet-based electronics manufacture are among the industrial applications in which liquid droplets are applied to a surface. But minuscule air bubbles that get trapped beneath the droplet as it lands can ...
