Nanoscale cluster structure of O2 gas-filled nanobubbles in O2 gas-supersaturated alkaline solution
Keywords:Di-oxygen gas filled nanobubble, nanoscale cluster structure, aggregation kinetics, high dilution
AbstractThere exists a close parallelism between gas-filled nanobubble solutions and ultra-high dilutions. Both these solutions contain Brownian nano-sized bubbles. We have studied aggregation kinetics of O2 gas-filled Brownian nanobubbles and their nanoscale cluster structure in 0.1M NaCO3 with NanoSight Particle Tracking Ananlysis (NTA) and transmission electron microscopy (TEM). A number of discrete peaks in a NTA size distribution of O2 nanobubbles in 0.1M NaCO3 eight days later after production are closely related to the existence of stable nanobubble clusters composed of 6-9nm nanobubbles that are inferred from the internal void size observed with TEM. Recent reports on 1HNMR of nanobubble water and its biological effects of wheat germination by Ohshitaâ€™s group may correlate with Demangeat`s NMR studies and germination experiments performed by many groups since the first publication by Lily Kolisco in 1923. Demangeatâ€™s has recently published a review on the essential role of succussion that can cause nanobubble formation.
