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
What Are Little Boys Made Of? Iona and Peter Opie, this first appears in a manuscript by the English poet Robert Southey (1774–1843), who added the stanzas other than the two below. Though it is not mentioned elsewhere in his works or papers, it is generally agreed to be by him. The relevant section in the version attributed to Southey was: <poem> What are little boys made of What are little boys made of Snips & snails & puppy dogs tails And such are little boys made of. What are little girls made of Sugar & spice & all things nice</poem> Extracts from the nursery rhyme
