Dishwashing liquid harm household silver, fine glassware, anything with gold leaf, disposable plastics, and any objects made of brass, bronze, cast iron, pewter, tin, or wood, especially when combined with hot water and the action of a dishwasher. When dishwashing liquid is used on such objects it is intended that they be washed by hand. Hand dishwashing detergents utilize surfactants to play the primary role in cleaning. The reduced surface tension of dishwashing water, and increasing solubility of modern surfactant mixtures, allows the water to run off the dishes in a dish rack very quickly. However, most people also rinse the dishes

Surface tension-driven nanoelectromechanical relaxation oscillator This page is a fragment, additional input from experts is wanted to fix any errors or add any relevant content to the article. A surface tension-driven nanoelectromechanical relaxation oscillator, or NEMRO for short, is currently the world's smallest motor. Constructed from a 200-nanometer-long nanotube, a pair of liquid indium spheres, one measuring 5 nanometers across and the other 15 nanometers across. Electricity flows across the nanotube from the large sphere to the smaller sphere, causing the spheres to shuffle atoms between the large sphere and the small sphere, making the larger sphere
