A highly light-absorbent and tunable material
By layering different two-dimensional materials, physicists at the University of Basel have created a novel structure with the ability to absorb almost all light of a selected wavelength. The achievement...
Calculating the best fabrication strategy for organic electronic components
Semiconductors made of organic materials, e.g. for light-emitting diodes (OLEDs) and solar cells, could replace or supplement silicon-based electronics in the future. The efficiency of such devices depends crucially on...
A team of international physicists join forces in hunt for sterile neutrinos
An international group of more than 260 scientists have produced one of the most stringent tests for the existence of sterile neutrinos to date. The scientists from two major international...
Korean baseball increases fan capacity to 25% at stadiums
The Korea Baseball Organization, which began allowing fans back to games last month, will raise its stadium capacity from 10% to 25% starting Tuesday, the league announced.
Sen. Ron Johnson subpoenas FBI over its Russia probe
Republican Sen. Ron Johnson has subpoenaed the Federal Bureau of Investigation to hand over records concerning its probe of Russia meddling in the 2016 presidential election.
How airplanes counteract St. Elmo’s Fire during thunderstorms
At the height of a thunderstorm, the tips of cell towers, telephone poles, and other tall, electrically conductive structures can spontaneously emit a flash of blue light. This electric glow, known as a...
Electronic components join forces to take up 10 times less space on computer chips
Electronic filters are essential to the inner workings of our phones and other wireless devices. They eliminate or enhance specific input signals to achieve the desired output signals. They are...
U.S. hypersonic weapon system completes second test on B-52 Stratofortress
The U.S. Air Force and Lockheed Martin said Monday they have completed the second successful hypersonic air-to-ground weapon test on a B-52 Stratofortress bomber out of Edwards Air Force Base,...

Seeing chemical reactions with music
Albert Einstein once said, "I see my life in terms of music." Perhaps inspired by his words, scientists at the Center for Self-assembly and Complexity (CSC), within the Institute for...
Theoretical study shows that matter tends to be ordered at low temperatures
Classical phase transitions are governed by temperature. One of the most familiar examples is the phase transitions of water from solid to liquid to gas. However, other parameters govern phase...
Breaking molecular traffic jams with finned nanoporous materials
Thousands of chemical processes used by the energy industry and for other applications rely on the high speed of catalytic reactions, but molecules frequently are hindered by molecular traffic jams...
Breaking molecular traffic jams with finned nanoporous materials
Researchers are reporting the invention of a new class of porous catalysts that will speed up reactions, breaking the molecular traffic jam that can slow them down. The discovery has...
