Clouds have a profound effect on the climate, but we know surprisingly little about how they form. Erika Sundén, researcher at the University of Gothenburg, Sweden, has studied how extremely small cloud particles can dispose of excess energy. This knowledge is necessary to understand processes in the atmosphere that affect global climate change. The models that have been built to describe climate change contain a major source of uncertainty, namely the effects of clouds. The...

Fool's gold may prove an unlikely alternative to overexploited catalytic materials Catalytic materials, which lower the energy barriers for chemical reactions, are used in everything from the commercial production of chemicals to catalytic converters in car engines. However, with current catalytic materials becoming increasingly expensive, scientists are exploring viable alternatives. Researchers at the University of Cambridge have now discovered that the sulphide material iron pyrite,...

Researchers from North Carolina State University and West Virginia University have developed a new technology that can reduce air pollutant emissions from some chicken and swine barns, and also reduce their energy use by recovering and possibly generating heat. Specifically, the research team designed, built, and evaluated a proof-of-concept unit that incorporates a biofilter and a heat exchanger to reduce ammonia emissions from livestock barns, while also tempering — or heating up...

In chemistry, salt is a general term used for ionic compounds composed of positively charged cations and negatively charged anions, so that the product is neutral and without a net charge. These ions can be inorganic (Cl-) as well as organic (CH3-COO-) and monoatomic (F-) as well as polyatomic ions (SO42-). Solutions of salts in water are called electrolytes. Electrolytes as well as molten salts conduct electricity. Zwitterions are salts that contain an anionic center and a cationic...
