Scientists at Northwestern University in Evanston, Illinois have developed a hydrogel integrated with zirconium-based robust metal-organic frameworks (MOFs) that rapidly degrades organophosphate-based nerve agents used in chemical warfare. Unlike existing powdered MOF adsorbents, this hydrogel composite does not require added water and may be easily scaled up for use in protective masks or clothing. The work appears July 14 in the journal Chem Catalysis.
Skid marks left by cars are often analyzed for their impression patterns, but they often don't provide enough information to identify a specific vehicle. UCF Chemistry Associate Professor Matthieu Baudelet and his forensics team at the National Center for Forensic Science, which was established at UCF in 1997, may have just unlocked a new way to collect evidence from those skid marks.
A new study by five doctoral students in neuroscience at the University of Minnesota Medical School calls attention to a lack of regulation and unknown long-term health effects of tear gas. Based on their research, the group recommends changing the protocols around the use of tear gas as a crowd control measure at both the local and national level.
A new study performed in human lung airway cells is one of the first to show a potential link between exposure to organophosphate pesticides and increased susceptibility to COVID-19 infection. The findings could have implications for veterans, many of whom were exposed to organophosphate pesticides during wartime.
From engineered pandemics to city-toppling cyber attacks to nuclear annihilation, life on Earth could radically change, and soon. Scientists will forecast the fate of the planet at a press conference during the 2021 APS April Meeting.
A Northwestern research team including Professors Justin Notestein and Peter Stair has demonstrated a new approach to chemical catalysis that results in higher yields of propylene -- the basis for many plastics -- using less energy.
At the heart of ice crystals, often, are aerosol particles onto which ice can form more easily than in the open air. It's a bit mysterious how this happens, though. New research shows how crystals of organic molecules, a common component of aerosols, can get the job done.
Using thin films -- no more than a few pieces of notebook paper thick -- of a common explosive chemical, researchers from Sandia National Laboratories studied how small-scale explosions start and grow.
Pervoskite nanocrystals, a key component of emerging solar energy technology, are being used in Australia to develop a new, rapid-response detection mechanism for fumigants, pollutants and nerve agents. The technology, developed by the ARC Centre of Excellence for Exciton Science, Australia's national science agency CSIRO and the Department of Defence, could be used to protect emergency services, defence personnel and agricultural workers.
Exposure to some odorless, colorless and tasteless gases, such as nerve agents, can be toxic or even lethal. And having the ability to detect other types of vapors could save people from eating spoiled or rotten food. Easy-to-use portable devices could, therefore, go a long way toward protecting the public. Now researchers reporting in ACS Materials Letters have created a pen-like sensor that changes color when exposed to harmful gases.
