A team of researchers has proposed an indirect optical method for determining internal temperatures of opaque packed beds based on phosphor thermometry. This method enables simultaneous multi-point measurements using an image-based separation of the superimposed luminescence originating from sources at different locations. …read more […]

Substitutional doping from foreign elements stands out as a preferred method for precisely tailoring the electronic band structure, conduction type, and carrier concentration of pristine materials. In the realm of three-dimensional (3D) monocrystalline silicon, for instance, the introduction of boron (B) and nitrogen (N) atoms as acceptor and donor dopants, respectively, has proven highly effective in enhancing carrier mobility. This improvement positions silicon for advanced applications in integrated circuits. …read more […] Universe Today has examined the potential for sending humans to Jupiter’s icy moon, Europa, the planet Venus, and Saturn’s largest moon, Titan, all despite their respective harsh environments and vast distances. These conversations with planetary science experts determined that humans traveling to these worlds in the foreseeable future could be possible, despite the harsh conditions and travel time, specifically to Titan. …read more […] Red dwarf exoplanet habitability is a hot topic in space science. These small dim stars host lots of exoplanets, including small rocky ones the size of Earth. But the little stars emit extremely powerful flares that can damage and strip away atmospheres. …read more […] In a groundbreaking cosmic quest, the SETI Institute’s Commensal Open-Source Multimode Interferometer Cluster (COSMIC) at the Karl G. Jansky Very Large Array (VLA) is expanding the search for extraterrestrial intelligence (SETI). …read more […] An historic private mission to land on the moon was facing potential failure Monday due to technical problems, in a blow to America’s hopes of placing its first robot on the lunar surface in five decades. …read more […] A team of Chinese researchers used a novel theory to invent a new type of ultrathin optical crystal with high energy efficiency, laying the foundation for next-generation laser technology. …read more […] Hold your hands out in front of you, and no matter how you rotate them, it’s impossible to superimpose one over the other. Our hands are a perfect example of chirality—a geometric configuration by which an object cannot be superimposed onto its mirror image. …read more […] It’s not every day astronomers say, “What is that?” After all, most observed astronomical phenomena are known: stars, planets, black holes and galaxies. But in 2019 the newly completed ASKAP (Australian Square Kilometer Array Pathfinder) telescope picked up something no one had ever seen before: radio wave circles so large they contained entire galaxies in their centers. …read more […] For the first time, researchers have demonstrated the remarkable ability to perturb pairs of spatially separated yet interconnected quantum entangled particles without altering their shared properties. …read more […] Gravitational waves are ripples in the fabric of spacetime that travel at the speed of light. These are produced in some of the most violent events in the universe, such as black-hole mergers, supernovae, or the Big Bang itself. Since their first detection in 2015, and after three observing runs, the Advanced LIGO and Virgo detectors have detected around 100 such waves. …read more […] 
 
 NASA has onboarded another integral partner to its lunar plans by striking a deal with the United Arab Emirates to build part of its lunar Gateway space station and send one of the Arab country’s astronauts on a future Artemis mission. …read more […] Using a spectral synthesis code designed to simulate conditions in interstellar matter, astronomers have explored a faint tidal disruption event (TDE) designated iPTF16fnl. Results of the study, published Dec. 29 on the pre-print server arXiv, deliver important insights into the properties of this TDE. …read more […] |
