A Northwestern University environmental engineer has received a U.S. patent for a treatment device that renders perchlorate — a thyroid-damaging ingredient of rocket fuel and a drinking water problem — harmless. The applications extend beyond the safety of drinking water and this one pollutant.
Bruce E. Rittmann, John Evans Professor of Environmental Engineering at the Robert R. McCormick School of Engineering and Applied Science, received U.S. Patent No. 6,387,262 for a hollow-fiber membrane biofilm reactor, that, through a natural biochemical process of electron transfer, turns perchlorate into innocuous chloride.
The cost-effective and environmentally friendly system also works on nitrate, a contaminant from agricultural fertilizers that can cause methemoglobinemia, or blue-baby syndrome, in infants, and is expected to be successful with other oxidized pollutants, such as bromate, selenate, heavy metals, radionuclides, and a range of chlorinated solvents, including trichloroethylene, a problem in the semiconductor industry.

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
