pH jump kinetics in colliding microdroplets: accelerated synthesis of azamonardine from dopamine and resorcinol
Emily K. Brown, Grazia Rovelli, Kevin R. Wilson
Abstract
by measuring the formation of azamonardine. The reaction was observed to occur 1.5 to 7.4 times faster in 9-35 micron droplets compared to the same reaction conducted in a macroscale container. A kinetic model of the experimental results suggests that the acceleration mechanism arises from both the more rapid diffusion of oxygen into the droplet, as well as increased reagent concentrations at the air-water interface.
