Jan 11, 2024 (Nanowerk News) When light goes through a material, it often behaves in unpredictable ways. This phenomenon is the subject of an entire field of study called “nonlinear optics”, which is now integral to technological and scientific advances from laser development and optical frequency metrology, to gravitational wave...
Bulky additives could make cheaper solar cells last longer
Jan 11, 2024 (Nanowerk News) An insight into preventing perovskite semiconductors from degrading quickly, discovered at the University of Michigan, could help enable solar cells estimated to be two to four times cheaper than today's thin-film solar panels. The findings have been published in Cell ("Molecular Design of Defect Passivators...
Our surprising magnetic galaxy
Jan 11, 2024 (Nanowerk News) A team of astronomers created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general picture, but the new study reveals that magnetic fields in the spiral arms...
Researchers use spinning metasurfaces to craft compact thermal imaging system
Jan 11, 2024 (Nanowerk News) Researchers have developed a new technology that uses meta-optical devices to perform thermal imaging. The approach provides richer information about imaged objects, which could broaden the use of thermal imaging in fields such as autonomous navigation, security, thermography, medical imaging and remote sensing. “Our method...
Neural implant can read deep neural activity from the brain surface
Jan 11, 2024 (Nanowerk News) Researchers at the University of California San Diego have developed a neural implant that provides information about activity deep inside the brain while sitting on its surface. The implant is made up of a thin, transparent and flexible polymer strip that is packed with a...
First direct imaging of small noble gas clusters at room temperature

This achievement opens up exciting possibilities for fundamental research in condensed matter physics and applications in quantum information technology. The key to...
AI discovers that not every fingerprint is unique
Jan 11, 2024 (Nanowerk News) From “Law and Order” to “CSI,” not to mention real life, investigators have used fingerprints as the gold standard for linking criminals to a crime. But if a perpetrator leaves prints from different fingers in two different crime scenes, these scenes are very difficult to...
Using Berry phase monopole engineering for high-temperature spintronic devices
Jan 11, 2024 (Nanowerk News) Spin-orbit torque (SOT), an important phenomenon for developing ultrafast and low-power spintronic devices, can be enhanced through Berry phase monopole engineering at high temperatures, shown in a new study by Tokyo Tech researchers. In this study, the temperature dependence of the intrinsic spin Hall effect...
Observing single protein with infrared nanospectroscopy
Jan 10, 2024 (Nanowerk News) Infrared vibrational spectrum of a single protein is observed using advanced measurement techniques based on near-field optical microscopy. This method utilizes light confined at the nanometer scale, allowing for the detailed analysis of extremely small samples, which was previously challenging with conventional infrared spectroscopy. The...
