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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
