A novel micro-valve for use in reliable small-scale thrusters

Researchers investigate electrowetting of ionic liquids with the potential to be used in micro-valve thrusters in space

The changing shapes of liquid droplets on charged solid surfaces have been widely studied for decades – but only recently have physicists begun to explore how this ‘electrowetting’ behaviour can be enhanced through the use of salts in their liquid states. In their research, Professor Weizong Wang and Mr Jinrui Zhang at Beihang University, Beijing, China, have exploited this effect […]
