Nov 23, 2022 (Nanowerk News) Although blockchain is best known for securing digital currency payments, researchers at the Department of Energy’s Oak Ridge National Laboratory are using it to track a different kind of exchange: It’s the first time blockchain has ever been used to validate communication among devices on the electric...
Spin correlation between paired electrons demonstrated
Nov 23, 2022 (Nanowerk News) Physicists at the University of Basel have experimentally demonstrated for the first time that there is a negative correlation between the two spins of an entangled pair of electrons from a superconductor. For their study, the researchers used spin filters made of nanomagnets and quantum...
A far-sighted approach to machine learning (w/video)
Nov 23, 2022 (Nanowerk News) Picture two teams squaring off on a football field. The players can cooperate to achieve an objective, and compete against other players with conflicting interests. That’s how the game works. Creating artificial intelligence agents that can learn to compete and cooperate as effectively as humans...
Researchers reveal effects of defects on electron emission property of graphene electrodes
Nov 23, 2022 (Nanowerk News) After studying the effects of irradiation defects on the work function of graphene electrodes in thermionic energy converters (TECs), a research team found that the generation of defects in graphene through irradiation would increase the work function and reduce the electron emission capacity. This results...
Glass-like shells of diatoms help turn light into energy in dim conditions
Nov 22, 2022 (Nanowerk News) A new study has revealed how the glass-like shells of diatoms help these microscopic organisms perform photosynthesis in dim conditions. A better understanding of how these phytoplankton harvest and interact with light could lead to improved solar cells, sensing devices and optical components. “The computational...
Microchannel-containing nanofiber aerogels with small protein molecule enable accelerated diabetic wound healing
Nov 22, 2022 (Nanowerk News) A collaborative team of scientists from the Terasaki Institute for Biomedical Innovation and the University of Nebraska Medical Center has developed a fibrous aerogel that promotes faster and more effective healing of diabetic wounds. As detailed in their publication in Advanced Functional Materials ("Nanofiber Aerogels with...
Webb reveals an exoplanet atmosphere as never seen before
Nov 22, 2022 (Nanowerk News) NASA’s James Webb Space Telescope just scored another first: a molecular and chemical profile of a distant world’s skies. While Webb and other space telescopes, including NASA’s Hubble and Spitzer, previously have revealed isolated ingredients of this broiling planet’s atmosphere, the new readings from Webb...
Astronomers observe innermost structure of quasar jet
Nov 22, 2022 (Nanowerk News) At the heart of nearly every galaxy lurks a supermassive black hole. But not all supermassive black holes are alike: there are many types. Quasars, or quasi-stellar objects, are one of the brightest and most active types of supermassive black holes. An international group of...
Study shows chemical coatings can affect microparticles ‘swimming’ in mucus solutions
Nov 22, 2022 (Nanowerk News) Collaborative research between SMU nanorobotics authority MinJun Kim’s Biological Actuation, Sensing, and Transport (BAST) Lab and international research and engineering company ARA has demonstrated for the first time that certain chemical coatings, applied to micro/nanoparticles, can alter their swimming propulsion within biological fluids. The joint...
Embroidery as low-cost solution for making wearable electronics
Nov 22, 2022 (Nanowerk News) Embroidering power-generating yarns onto fabric allowed researchers to embed a self-powered, numerical touch-pad and movement sensors into clothing. The technique offers a low-cost, scalable potential method for making wearable devices. “Our technique uses embroidery, which is pretty simple – you can stitch our yarns directly...
