Get a group of scientists together and mention the word "chlorine" and watch the sparks start to fly. Thats exactly what happened at a forum on a different, but related, topic of sustainability, sponsored by the news magazine Chemical & Engineering News, a publication of the American Chemical Society, the worlds largest scientific society.
As a result of a "vigorous and provocative debate" about chlorine at that forum, the magazines editors asked two leading experts in the field of chlorine chemistry - Terrence Collins, professor of chemistry at Carnegie Mellon University, and C.T. (Kip) Howlett Jr., executive director of the Chlorine Chemistry Council and vice president of the American Chemistry Council - each representing opposing viewpoints, to participate in a special "point-counterpoint" exchange, which appears in the magazines Oct. 18 issue.
Collins charges that the dangers of chlorine are not being adequately addressed by industry or academe. He says alternatives to chlorine and chlorine processes must be pursued. Howlett contends that industry is, in fact, succeeding in lessening the impact of chlorine on the environment. He cites numerous positive contributions that chlorine has made to society.
Despite the long-standing and passionate controversy over chlorine, Collins and Howlett managed to agree on at least one thing: disinfection of drinking water supplies with chlorine has been a lifesaver for people around the world. According to Collins, "... water disinfection with chlorine probably holds the record for saving human lives ..." Howletts response, "I agree."
The American Chemical Society is a nonprofit organization, chartered by the U.S. Congress, with a multidisciplinary membership of more than 159,000 chemists and chemical engineers. It publishes numerous scientific journals and databases, convenes major research conferences and provides educational, science policy and career programs in chemistry. Its main offices are in Washington, D.C., and Columbus, Ohio.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
