ABSTRACT: Microbubble
technology is now available in a wide range of industrial fields. The liquid
containing microbubbles possesses a large number of air-liquid interfaces, and
also generates radicals during bubble collapse. Here, we synthesized ZnO powder
to explore the potential of microbubbles as starting materials for the
formation of crystalline micro- or nanoparticles. The bubbles facilitated the
growth of ZnO microneedles in high yields, and enhanced the reaction by
radicals generated on bubble collapsing.
