Metal-organic frameworks (MOFs) are porous, crystalline materials that can trap compounds within their molecular cavities, giving them a wide range of applications in gas storage and separation, carbon capture, and in the catalysis of chemical reactions, to name a few. A new range of applications are now being investigated by converting crystalline MOFs into liquid and/or glassy states.
The materials the United States and other countries plan to use to store high level nuclear waste will likely degrade faster than anyone previously knew, because of the way those materials interact, new research shows. The findings, published today in the journal Nature Materials, show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.
Researchers at Northwestern University and Argonne National Laboratory have developed a new material that opens doors for a new class of neutron detectors. The semiconductor-based detector is highly efficient, stable, and can be used both in small, portable devices for field inspections and very large detectors that use arrays of crystals.
Chemists have found a new use for the waste product of nuclear power -- transforming an unused stockpile into a versatile compound which could be used to create valuable commodity chemicals as well as new energy sources.
Northwestern University scientists have successfully combined a nanomaterial effective at destroying toxic nerve agents with textile fibers. This new composite material one day could be integrated into protective suits and face masks for use by humans facing hazardous conditions, such as chemical warfare. The material, a zirconium-based metal-organic framework, degrades in minutes some of the most toxic chemical agents known to mankind: VX and soman (GD), a more toxic relative of sarin.
According to a new study led by a team from The University of New Mexico, centuries-old laws about the behavior of gas mixtures do not apply in the presence of shock waves. This finding could have potential impact on everything that involves mixtures of gases exposed to a shock wave, for example, during combustion in an engine.
A physicist at the University of California, Riverside, has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium. The calculations take scientists a step closer to realizing a gamma-ray laser.
A scientific team from the Department of Energy's Oak Ridge National Laboratory and Vanderbilt University has made the first experimental observation of a material phase that had been predicted but never seen. The newly discovered phase couples with a known phase to enable unique control over material properties -- an advance that paves the way to eventual manipulation of electrical conduction in two-dimensional materials such as graphene.
New research from the University of Pittsburgh's Swanson School of Engineering introduces a revolutionary treatment for these infections. The group, led by Tagbo Niepa, Ph.D., is utilizing electrochemical therapy (ECT) to enhance the ability of antibiotics to eradicate the microbes.
Purdue University researchers have developed a new process to help overcome the brittle nature of ceramics and make it more ductile and durable. The Purdue team calls the process 'flash sintering,' which adds an electric field to the conventional sintering process used to form bulk components from ceramics.
