Scientists have developed a new way to trap small particles with light. Building on the Nobel Prize winning technique of optical tweezers (Arthur Ashkin, 2018), a team of physicists, led by Dr. David Phillips at the University of Exeter, has advanced the possibilities of optical trapping. Go to Source A new publication in Opto-Electronic Science discusses boosting UV light absorption in a 2D semiconductor with quantum dot hybrids for enhanced light emission. Go to Source Researchers have developed a novel method for generating structured terahertz light beams using programmable spintronic emitters. This breakthrough offers a significant leap forward in terahertz technology, enabling the generation and manipulation of light with both spin and orbital angular momentum at these frequencies for the first time. Go to Source Moving large amounts of regolith is a requirement for any long-term mission to the moon or Mars. But so far, humanity has only sent systems capable of moving small amounts of soil at a time—primarily for sample collection. Sending a large, dedicated excavator to perform such work might be cost-prohibitive due to its weight, so […] It seems like every month a new story appears announcing the discovery of thousands of new asteroids. Tracking these small body objects from ground and even space-based telescopes helps follow their overall trajectory. But understanding what they’re made of is much more difficult using such “remote sensing” techniques. Go to Source CubeSats are becoming ever more popular, with about 2,400 total launched so far. However, the small size limits their options for fundamental space exploration technologies, including propulsion. They become even more critical when mission planners design missions that require them to travel to other planets or even asteroids. Go to Source Tandem LEDs offer an effective way to integrate different light-emitting technologies for better display that meets Rec. 2020 color gamut standard. Now, scientists in China have developed a stable, efficient and high-color purity green LED with a tandem structure by combining perovskite LED and organic LED technologies.

Go to Source Prof. Long Shibing and his team from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) have proposed a novel strategy for a high-energy photon detector with high sensitivity and response speed by coupling the interface pyroelectric effect with the photoconductive effect based on polycrystal Ga-rich GaOx (PGR-GaOx) […] Stimulated Raman scattering (SRS) microscopy is an optical vibrational spectroscopic imaging technique and has emerged as an appealing label-free imaging tool for tissue and cell imaging and characterization with high biochemical specificity. Go to Source Madison County Sheriff’s Office K-9 Archer assisted in the arrest of a felony suspect before the episode; he was rushed to a veterinary hospital, where he later died Go to Source Neutron stars are extreme and mysterious objects that astrophysicists cannot see inside. With a radius of around 12 kilometers, they can have more than twice the mass of the sun. The matter in them is packed up to five times as densely as in an atomic nucleus; with black holes, they are the densest objects […] A research team has constructed a coherent superposition of quantum evolution with two opposite directions in a photonic system and confirmed its advantage in characterizing input-output indefiniteness. The study was published in Physical Review Letters. Go to Source |
