"Aqua-B’s patented nano-bubble/droplet generation methods are based on electrostriction phenomena induced by application of electric fields, which “suck in” gas/minority-phase molecules into the mother solvent – in a very low-energy way, that is suited ideally for remote off-Grid, solar-with-battery-powered generation of the “nano-phase”, as we might usefully dub it. This uptake is often species-selective/preferential, so we can effect good levels of gas separation/enrichment, for instance; a concrete example is oxygen enrichment from (ambient-pressure) air to about two-thirds the composition (versus nitrogen) in NB form, whereas it is one-fifth in air."
