Aug 17, 2022 (Nanowerk News) One speaks of a superconducting diode effect when a material behaves like a superconductor in one direction of current flow and like a resistor in the other. In contrast to a conventional diode, such a superconducting diode exhibits a completely vanishing resistance and thus no...
Superatomic magnetic cluster opens the door to new nanomaterials
Aug 17, 2022 (Nanowerk News) Industry uses magnetic materials in applications ranging from data storage and cell phones to motors and sensors. Researchers are always looking for new magnetic particles as the technology moves to smaller and smaller scales. In this study (Journal of the American Chemical Society, "High-Spin Superatom...
Algorithm learns to correct 3D printing errors for different parts, materials and systems
Aug 17, 2022 (Nanowerk News) Engineers have created intelligent 3D printers that can quickly detect and correct errors, even in previously unseen designs, or unfamiliar materials like ketchup and mayonnaise, by learning from the experiences of other machines. The engineers, from the University of Cambridge, developed a machine learning algorithm...
Mars model provides method for landing humans on Red Planet
Aug 17, 2022 (Nanowerk News) A mathematical model developed by space medicine experts from The Australian National University (ANU) could be used to predict whether an astronaut can safely travel to Mars and fulfil their mission duties upon stepping foot on the Red Planet (npj Microgravity, "Computational modeling of orthostatic...
A new neuromorphic chip for AI on the edge, at a small fraction of the energy and size of today’s compute platforms
Aug 17, 2022 (Nanowerk News) An international team of researchers has designed and built a chip that runs computations directly in memory and can run a wide variety of artificial intelligence (AI) applications–all at a fraction of the energy consumed by computing platforms for general-purpose AI computing. The NeuRRAM neuromorphic...
Floating ‘artificial leaves’ ride the wave of clean fuel production
Aug 17, 2022 (Nanowerk News) Researchers have developed floating ‘artificial leaves’ that generate clean fuels from sunlight and water, and could eventually operate on a large scale at sea. The researchers, from the University of Cambridge, designed ultra-thin, flexible devices, which take their inspiration from photosynthesis – the process by...
Extracting gold from waste with graphene (w/video)
Aug 17, 2022 (Nanowerk News) Throughout history, alchemists believed in the existence of the philosopher’s stone: a substance that could turn cheap substances into precious gold. Now scientists from The University of Manchester, Tsinghua University in China and the Chinese Academy of Sciences have shown that graphene can be a...
Researchers boost sensitivity and speed of Raman microscopy technique
Aug 17, 2022 (Nanowerk News) Researchers have developed a label-free and non-invasive Raman spectroscopy approach that can acquire microscopic images of biological samples and identify a wide range of biomolecules with unprecedented speed and sensitivity. “Our work could lead to a non-invasive, label-free and user-friendly device for clinical use,” said...
Black hole collisions could help us measure how fast the universe is expanding
Aug 17, 2022 (Nanowerk News) A black hole is usually where information goes to disappear—but scientists may have found a trick to use its last moments to tell us about the history of the universe. In a new study (Physical Review Letters, "Spectral sirens: Cosmology from the full mass distribution...
Despite fears, 3D printing has positive effects on global trade
Aug 17, 2022 (Nanowerk News) 3D printing technology enables economies to produce goods locally, so conventional wisdom has been that it would dramatically reduce international trade; however, new University of California San Diego and World Bank research presents robust evidence that 3D printing expanded trade. The paper coauthored by Caroline...
