Equatorial rings that break up into uniform microdroplets could be an alternative to microfluidic emulsification techniques
US scientists have discovered a new way to controllably produce tiny liquid droplets ‘on zap’, which is a potential alternative to existing microfluidic methods. New York University’s Quentin Brosseau and Petia Vlahovska at Northwestern University have found that electric fields can make large droplets first produce flat rims around their middle, then rings. ‘I find the shedding of rings from the rim most fascinating,’ Vlahovska tells Chemistry World. ‘It is very counterintuitive!’
