Son of Carwash, the Self-Cleaning House by Patricia Leigh Brown, The New York Times, January 17, 2002. The story of Frances Gabe and her amazing, waterproof, plastic ...
How water filters work. Thanks largely to an unusual molecular structure, water is amazingly good at dissolving things. (We look at this in more detailed in our main article on water.)Sometimes that's helpful: if you want to bust the dust from your jeans, simply throw them in your washing machine with some detergent and the water and soap will pull the muck away like a magnet.
In chemistry, photocatalysis is the acceleration of a photoreaction in the presence of a photocatalyst, the excited state of which "repeatedly interacts with the reaction partners forming reaction intermediates and regenerates itself after each cycle of such interactions."[1] In many cases, the catalyst is a solid that upon irradiation with UV- or visible light generates…
