Over the next few weeks researchers at the National Nuclear Security Administration’s Sandia National Laboratories will begin testing innovative ways to treat arsenic-contaminated water in an effort to reduce costs to municipalities of meeting the new arsenic standard issued by the U.S. Environmental Protection Agency (EPA). The testing is sponsored by the Arsenic Water Technology Partnership (AWTP), a multiyear-program funded by a congressional appropriation through the U.S. Department of Energy.
"The goals of the program are to develop, demonstrate, and disseminate information about cost-effective water treatment technologies in order to help small communities in the Southwest and other parts of the country comply with the new EPA standard," says Malcolm Siegel, Sandia Arsenic Treatment Technology Demonstration Project Manager.
The tests will be conducted at a geothermal spring used to supply drinking water to Socorro, N.M., a town of about 9,000 residents located 80 miles south of Albuquerque. Installation of test equipment will be completed in December by Sandians Randy Everett and Brian Dwyer, and regular operations will begin before Christmas following a preliminary "shakedown" period. Another member of the team, Alicia Aragon, will present results of laboratory studies supporting the pilot tests at the Fall Meeting of the American Geophysical Society in San Francisco next week.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
