Nov 20, 2023 (Nanowerk News) Researchers at the University of Warsaw's Faculty of Physics have superposed two light beams twisted in the clockwise direction to create anti-clockwise twists in the dark regions of the resultant superposition. The results of the research have been published in the journal Optica ("Azimuthal backflow...
Gold nanowire circuits enable smart wearables to monitor health signals and process information
Nov 20, 2023 (Nanowerk News) Wearable electronics that can monitor health and provide real-time feedback have long been envisioned as the future of personalized medicine. But most wearables today simply collect raw data to be processed later. Now, researchers have developed stretchable, multifunctional circuits made from gold nanowires that can...
For the first time, researchers observe the operating principle of so-called promoters in a catalytic reaction in real-time
Nov 20, 2023 (Nanowerk News) Catalysts are essential for numerous chemical technologies, ranging from exhaust gas purification to the production of valuable chemicals and energy carriers. Often, tiny traces of additional substances are used alongside catalysts to make them highly effective. These substances are referred to as "promoters." While playing...
What should replace the Turing test?
Nov 20, 2023 (Nanowerk News) In a paper published in Intelligent Computing ("What Should Replace the Turing Test?"), Philip Nicholas Johnson-Laird of Princeton University and Marco Ragni of Chemnitz University of Technology propose a novel alternative to the Turing test, a milestone test developed by computing pioneer Alan Turing. The...
Rare metal could offer revolutionary switch for future quantum devices
Nov 20, 2023 (Nanowerk News) Quantum scientists have discovered a rare phenomenon that could hold the key to creating a ‘perfect switch’ in quantum devices which flips between being an insulator and superconductor. Key Takeaways Researchers at the University of Bristol discovered a phenomenon in purple bronze that enables it...
Bioengineered viruses enable quantum leaps in biopyroelectric sensing and energy harvesting
Nov 20, 2023 (Nanowerk Spotlight) For decades, researchers have sought to understand and harness the pyroelectric effect in biological materials. Pyroelectricity refers to the phenomenon where heating or cooling a material with a nonzero spontaneous electric polarization changes the polarization, generating a temporary voltage. Many biological substances like bone, tendon,...
Tiny traps can provide new knowledge about difficult-to-treat diseases
Nov 20, 2023 (Nanowerk News) Proteins that form clumps occur in many difficult-to-treat diseases, such as ALS, Alzheimer’s, and Parkinson's. The mechanisms behind how the proteins interact with each other are difficult to study, but now researchers at Chalmers University of Technology, Sweden, have discovered a new method for capturing...
