Electroacoustics was used to study SDS-stabilized sunflower oil-in-water emulsions, with oil volume fractions between 2% and 50%. The dynamic mobility of the oil droplets was measured; the size and electric charge on the drops were calculated using formulas derived for dilute and concentrated system
We measured the dynamic mobility of a polystyrene latex at 1 MHz as a function of volume fraction using the ESA-8000. The volume fraction dependence is compared with a semiempirical equation as well as with some theoretical predictions. It turns out that our polystyrene latex exhibits a volume fract
