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.
Highlights
Microbubbles are defined as having diameters less than 50 μm, and have important technical applications in industrial fields [1]-[3]
ZnO crystals were grown from purified water, N2 MB water, and O3 MB water mediums
On the basis of the yield, crystal structure, and crystal shape, we reviewed whether the presence of the bubbles and radicals affected crystal growth
Summary
Microbubbles are defined as having diameters less than 50 μm, and have important technical applications in industrial fields [1]-[3]. Microbubbles can be generated in water by various methods. The gas bubbles in the liquid are fractured because of the centrifugal shearing force during rotation. Advantages of this method include the generation of bubbles of ~100 nm in diameters and the long-term stability [9]. (2014) Crystal Growth of ZnO Microneedles in Water Containing Microbubbles. Free radicals are generated from the bubbles even in the absence of ultrasound waves. The radicals generated by cavitation are used in sonochemistry [10] Such radicals have affected the crystal growth of ZnO [11], in which ZnO nanorods were aligned on a substrate. We synthesize ZnO microcrystals using water containing microbubbles (MB water), in order to demonstrate its potential in the field of nanomaterials
