Liquid marbles Liquid marbles provide a new approach to transport liquid mass on the solid surface, which sufficiently transform the inconvenient glass containers into flexible, user-specified hydrophobic coating composed of powders of hydrophobic materials. Since then, the applications of liquid marbles in no-loss mass transport, microfluidics and microreactors have been extensively investigated. However, liquid marbles only reflect the water behavior at the solid-air interface, while there is no report on the water behavior at the liquid-liquid interface, as a result of the so-called coalescence cascade phenomenon. When a water droplet is in contact with a water reservoir, it will quickly pinch off
American Specialty Toy Retailing Association to be observed on the second Saturday of each November. American Specialty Toy Retailing Association The American Specialty Toy Retailing Association, or "ASTRA", is an organization of manufacturers, manufacturers representatives, distributors and retailers of specialty toys (as compared to mass market product).
