Human digestive system is located in the upper right quadrant of the abdomen and below the diaphragm to which it is attached at one part, This is to the right of the stomach and it overlies the gall bladder. The liver produces bile, an important alkaline compound which aids digestion. Bile produced by the liver is made up of water (97%), bile salts, mucus and pigments, 1% fats and inorganic salts. Bilirubin is its major pigment. Bile acts partly as a surfactant which lowers the surface tension between either two liquids or a solid and a liquid and helps to emulsify the fats
Surface tension-driven nanoelectromechanical relaxation oscillator 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 shrink and the
