Book Description

Certain small solid particles are surface-active at fluid interfaces and thus are able to stabilize materials previously considered impossible to stabilize in their absence. Liquid marbles, particle-coated non-sticking liquid droplets, represent one of these materials. Preparation of liquid marbles was described only about 15 years ago and they are now widely studied by many research groups and numerous applications of liquid marbles have been advanced. The book is written for postgraduates and researchers working on the area who are training to become chemists, soft matter physicists, materials scientists, and engineers.
