Jul 25, 2024 (Nanowerk News) Trillions of periodical cicadas — several species of the genus Magicicada that emerge every 13 or 17 years — broke soil across the Eastern U.S. this summer. News outlets likened the event to Armageddon, an apocalypse or an invasion. But what about using words like...
Novel optical nanoscopy unveils ultrafast dynamics in nanomaterials
Jul 25, 2024 (Nanowerk News) Researchers from the University of California, Berkeley have developed cutting-edge nanoscale optical imaging techniques to provide unprecedented insights into the ultrafast carrier dynamics in advanced materials. Two recent studies, published in Advanced Materials ("Transient Nanoscopy of Exciton Dynamics in 2D Transition Metal Dichalcogenides") and ACS...
Soda cans, seawater, and caffeine
Jul 25, 2024 (Nanowerk News) A sustainable source for clean energy may lie in old soda cans and seawater. MIT engineers have found that when the aluminum in soda cans is exposed in its pure form and mixed with seawater, the solution bubbles up and naturally produces hydrogen — a...
A quantum sensor for atomic-scale electric and magnetic fields (w/video)
Jul 25, 2024 (Nanowerk News) In a scientific breakthrough, an international research team from Germany's Forschungszentrum Jülich and Korea's IBS Center for Quantum Nanoscience (QNS) developed a quantum sensor capable of detecting minute magnetic fields at the atomic length scale. This pioneering work realizes a long-held dream of scientists: an...
DNA nanopores with adjustable sizes enable precise control of molecular transport
Jul 25, 2024 (Nanowerk Spotlight) Controlling the flow of molecules across cellular membranes is a fundamental process in biology, one that scientists have long sought to replicate and enhance through synthetic means. At the heart of this endeavor are nanopores - tiny channels that regulate the passage of ions, small...
