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.

Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.
Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.
Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
