Sep 10, 2024 (Nanowerk Spotlight) Hand gestures have become a natural way to communicate with digital systems, but making machines understand those gestures with precision remains a technical challenge. While cameras and wearable devices have been used to translate hand movements into commands, both solutions come with trade-offs. Optical systems...
New nanofiltration material could remove long-lasting chemicals from water
Sep 10, 2024 (Nanowerk News) Water contamination by the chemicals used in today’s technology is a rapidly growing problem globally. A recent study by the U.S. Centers for Disease Control found that 98 percent of people tested had detectable levels of PFAS, a family of particularly long-lasting compounds also known...
MXenes shows talent as catalyst for oxygen evolution
Sep 10, 2024 (Nanowerk News) The MXene class of materials has many talents. An international team led by HZB chemist Michelle Browne has now demonstrated that MXenes, properly functionalised, are excellent catalysts for the oxygen evolution reaction in electrolytic water splitting. They are more stable and efficient than the best...
World’s strongest battery paves way for light, energy-efficient vehicles
Sep 10, 2024 (Nanowerk News) When cars, planes, ships or computers are built from a material that functions as both a battery and a load-bearing structure, the weight and energy consumption are radically reduced. A research group at Chalmers University of Technology in Sweden is now presenting a world-leading advance...
Unprecedented spin properties revealed in new artificial materials
Sep 10, 2024 (Nanowerk News) In conjunction with research staff from the Charles University of Prague and the CFM (CSIC-UPV/EHU) center in San Sebastian, CIC nanoGUNE’s Nanodevices group has designed a new complex material with emerging properties in the field of spintronics. This discovery, published in the journal Nature Materials...
Molecular level changes translate to big efficiency gains for organic solar cells
Sep 10, 2024 (Nanowerk News) Organic solar cells (OSCs) – promising alternatives to traditional inorganic solar cells – have many features that make them key players in a greener future. One of these features is tunable chemistry, which allows scientists to precisely adjust or modify the properties of chemical systems...
Exploring chaos in quantum systems with simple diffusion models
Sep 09, 2024 (Nanowerk News) Although systems consisting of many interacting small particles can be highly complex and chaotic, some can nonetheless be described using simple theories. Does this also pertain to the world of quantum physics? A research team led by Professor Monika Aidelsburger and Professor Immanuel Bloch from...
