Charged Drops Don't Splash
When a droplet falls on a surface, it spreads itself horizontally into a thin lamella. Sometimes -- depending on factors like viscosity, impact speed, and air pressure -- that drop splashes, breaking up along its edge into myriad smaller droplets. But a new study finds that a small electrical charge is enough to suppress a drop's splash. (Image and research credit: F. Yu et al.; via APS News) Read the full article
