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.
This survey study assessed public opinion in California (overall and by firearm ownership status) on two proposals to prevent firearm injuries: an amnesty program that would allow individuals to turn in ammunition magazines that hold more than 10 bullets, no questions asked; and a law that prevents someone from buying a gun for five years if they have had two or more driving under the influence of alcohol or drugs convictions in five years.
This year has had its share of science and technology advances from Army researchers. The U.S. Army CCDC Army Research Laboratory, the Army's corporate research laboratory, has the mission to discover, innovate and transition science and technology to ensure dominant strategic land power. The lab's chief scientist, Dr. Alexander Kott, picked the top 10 coolest advances from 2019 to showcase how Army scientists and engineers are supporting the Soldier of the future.
A new Tel Aviv University study reveals that small insects like mosquitos become perceptible to bats when they gather in large swarms. The findings could provide new insights into the evolution of bat echolocation and may affect technology in the defense industry.
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.
The way the scale armor works is that when in contact with a force, the scales converge inward upon one another to form a solid barrier. When not under force, they can 'move' on top of one another to provide varying amounts of flexibility dependent upon their shape and placement.
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.
Researchers at Carnegie Mellon University have developed a system that can accurately locate a shooter based on video recordings from as few as three smartphones.
