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
Toy soldier Toy soldier A toy soldier is a miniature figurine that represents a soldier. The term applies to depictions of uniformed military personnel from all eras, and includes knights, cowboys, pirates, samurai, and other subjects that involve combat-related themes. Toy soldiers vary from simple playthings to highly realistic and detailed models. The latter are of more recent development and are sometimes called model figures to distinguish them from traditional toy soldiers. Larger scale toys such as dolls and action figures may come in military uniforms, but they are not generally considered toy soldiers. Toy soldiers are made from all types of
