Imaging Shows Bubbles Could Make Energy-Efficient Nanoparticles
PRINCETON, N.J., Aug. 20, 2014 — High-speed cameras and UV-sensitive materials are helping advance understanding of bubbles — which could mean big things for nanoparticles. In fact, a system in which bubbles mix liquids is an energy-efficient route toward producing nanoparticles. A team from Princeton University has demonstrated that some of the tiny particles that are hurled when a bubble pops can actually be pushed down into the water when that water is covered with oil. Previously, such particles,...
