WASHINGTON, Feb. 20 (Xinhua) -- NASA scientists have described a chemical process to produce ingredients of water on the surface of the moon, using lunar elements and the solar wind. NASA said Wednesday that its scientists simulated a chemistry using computer program, showing when a stream of ...
Water, especially water to be used as tap water, is chlorinated to a degree slightly beyond the "break-point" and the residual chlorine is removed by dissolving in the chlorinated water by electrolysis a metal such as iron and aluminium which is capable of combining with the residual chlorine...
In process research and development (PR&D), the generation and manipulation of small-molecule drugs ranges from bench-scale (laboratory) chemistry to pilot plant manufacture to commercial production. A broad range of disciplines, including process chemistry (organic synthesis), analytical chemistry, proc...

Water has a very high heat capacity, but sand, dirt, trees, etc. have a low heat capacity As a consequence, the land heats up during the day and cools at night, while the temperature of the ocean remains constant This explains the direction of sea breezes –the air over land warms (...
The partially observable Markov decision process algorithm is used to construct a source likelihood map and update it in real time with environmental information from the sensors on autonomous underwater vehicle in search area. The artificial potential field algorithm uses the source likelihood map for...
