Abstract Scope |
It has been known for some time from freeze-fracture images that nanoparticles will bind to nanobubbles containing oxygen. More recently, we also presented evidence for nanoparticle/nanobubble cluster formation with nanobubbles that were generated with an alternating magnetic field (AMF) system. Specifically, our research has shown that these nanobubbles bind to nanoparticles of calcium carbonate at its solubility limit (5 x 10-4 M) based on nanoparticle tracking analysis (NTA) results. This ability to bind nanoparticles into clusters has important ramifications for preventing fouling and corrosion. Our research is currently focusing on generating nanobubbles that contain different gases, e.g. nitrogen, oxygen and argon, to study the effect of internal gas specie the nanobubbles’ ability to bind to nanoparticles. So far, evidence indicates that both oxygen and nitrogen allow for this binding process. Besides NTA, our experimental approach also includes Raman spectroscopy and liquid-phase transmission electron microscopy. |
