Scaling-up the bipolar coagulation process

Review on water electro-sprays and applications of charged drops with focus on the corona-assisted cone-jet mode for High Efficiency Air Filtration by wet electro-scrubbing of aerosols

“…In that case, the kinetics of product formation in the droplet depends on the surface temperature and on reactants concentrations in the liquid interface, limited by slow diffusion from gas phase. Since the same chemical reactions can be induced in volume when two droplets with opposite polarities are mixed by electrocoalescence, positive and negative ES have been used to increase the apparent reaction rate between the same reactants dissolved in controlled relative concentrations in droplets produced by ES with opposite polarities, (Borra et al, 1997a;Camelot et al, 1998;Borra et al, 1999a;Verdoold et al, 2000;Jaworek et al, 2008;Verdoold et al, 2011;Fu et al, 2012;Liu Q et al, 2014a;Xie et al, 2015;Tang J et al, 2016;Tang J et al, 2017a). Recent production of "smart" composite materials are also based on the production of nanoparticles in liquid droplets, as described above, from drying and eventual reaction in the liquid drop but as well by the direct ES of nano-suspensions, i.e.…”
