Liquid Marbles

Certain small solid particles are surface-active at fluid interfaces and thus are able to stabilize materials previously considered impossible to stabilize. Liquid marbles, particle-coated non-sticking liquid droplets, is one of these materials. This book discusses the principles, properties, and numerous applications of liquid marbles.
