When hydrophobic oil phase came in quiescent contact with aqueous phase, water-droplets and oil droplets were formed spontaneously near the oil|water interfaces in foreign phases. Droplets had uniform size and were electrically charged. They were electroactive when they contained electroactive species. Similar behavior was found in hydrogen-bubbled aqueous solution, in which bubbles with common size were stable. Expressions for size-distribution were derived on the concept of statistical mechanics, in which both the surface energy at the interfaces of droplets and the entropy of combinations of various sized droplets were taken into account. The stable size was the largest and the smallest. The largest droplets can be generated by balance of diffusion with gravitation.
