In a breakthrough that could lead to a new class of materials with functions found only in living systems, scientists at the University of California, Berkeley, have figured out a way to keep certain proteins active outside of the cell. The researchers used this technology to create mats that can soak up and trap chemical pollution.
Sensors that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so much that they can even detect diseases on a person's breath. Researchers from Drexel University and the Korea Advanced Institute of Science and Technology have made a discovery that could make our best 'chemical noses' even more sensitive.
In a new study, USC Viterbi School of Engineering professors used computer-based models to identify mechanisms or 'strategies' used by bacterial spores to evade attack from extreme temperatures, chemicals and radiation. Using complex mathematical techniques to examine spores at the molecular level, the team also determined the optimal conditions for killing harmful bacteria.
An joint research team, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has introduced the Hybrid-SOEC system with highest reported electrochemical performance in hydrogen production.
Society faces threats through the malicious use of chemical, biological, radiological, nuclear and/or explosive (CBRNE) materials. The detection of illicit trafficking or other criminal acts, as well as many security and safety applications, call for novel material analysis techniques and instruments.
New research suggests that few people, if any, should be asked to leave their homes after a big nuclear accident, which is what happened in March 2011 following the Fukushima Daiichi nuclear disaster.
A brand-new theory of the opening moments during the Chernobyl disaster, the most severe nuclear accident in history, based on additional analysis is presented for the first time in the journal Nuclear Technology, an official journal of the American Nuclear Society.
Policymakers' efforts to reduce threats from improvised explosive devices (IEDs) should include greater oversight of precursor chemicals sold at the retail level -- especially over the Internet -- that terrorists, violent extremists, or criminals use to make homemade explosives, says a new report from the National Academies of Sciences, Engineering, and Medicine.
New technology from Dartmouth College harnesses electronic signals in a smart fabric to detect, capture, concentrate and filter toxic chemicals.
Wearable sensors are revolutionizing the tech-world, capable of tracking processes in the body, such as heart rates. They're even becoming fashionable, with many of them sporting sleek, stylish designs. But wearable sensors also can have applications in detecting threats that are external to the body. Researchers now report in ACS Sensors a first-of-its kind device that can do just that. And to stay fashionable, they've designed it as a ring.
