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
Elgin Marbles until the mid-20th century and have suffered irreparable damage by previous cleaning methods employed by British Museum staff. As early as 1838, scientist Michael Faraday was asked to provide a solution to the problem of the deteriorating surface of the marbles. The outcome is described in the following excerpt from the letter he sent to Henry Milman, a commissioner for the National Gallery. The marbles generally were very dirty ... from a deposit of dust and soot. ... I found the body of the marble beneath the surface white. ... The application of water, applied by a sponge or soft
