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.

Andrew Tyowua is a lecturer in the Department of Chemistry, Benue State University, Makurdi, Nigeria. He obtained his B.Sc. degree in Chemistry (First Class) in 2009 from the same university and his Ph.D. degree in physical chemistry in 2014 from the University of Hull, United Kingdom, under the supervision of Professor B.P. Binks. His thesis was ‘Solid Particles at Fluid Interfaces: Emulsions, Liquid marbles, Dry oil powders and Oil foams’. Andrew Continued this work first as a postdoctoral fellow at the same university in 2015 and now as the founder of ‘Applied Colloid Science and Catalysis Group’, Chemistry Department, Benue State University, Makurdi, Nigeria where he is currently teaching and researching. Andrew has co-authored more than five research articles in referenced journals like Soft Matter and Langmuir and has presented papers in many scientific conferences on colloid and surface science. Andrew is a member of the Royal Society of Chemistry, London, United Kingdom, the American Chemical Society and the Chemical Society of Nigeria.
