Feb 16, 2023 (Nanowerk News) Researchers from North Carolina State University and the University of North Carolina at Chapel Hill used chiral phonons to convert wasted heat into spin information – without needing magnetic materials. The finding could lead to new classes of less expensive, energy-efficient spintronic devices for use...
Smooth sailing for electrons in graphene
Feb 16, 2023 (Nanowerk News) Physicists at the University of Wisconsin–Madison directly measured, for the first time at nanometer resolution, the fluid-like flow of electrons in graphene. The results appear in the journal Science ("Imaging the breaking of electrostatic dams in graphene for ballistic and viscous fluids"). A heatmap of...
New nanosecond water disinfection method is more environmentally friendly
Feb 16, 2023 (Nanowerk News) Having safe drinking water is vital for public health, but traditional methods of disinfection cause their own environmental problems. Chlorine is cheap and easy to use in centralized water systems, but at the expense of harmful chemical byproducts. Georgia Institute of Technology researchers have found...
New neural network method improves microscopic distance measurements between colored points in three dimensions
Feb 16, 2023 (Nanowerk News) Fluorescence microscopy is a widely used technique in the life sciences that enables scientists to see specific parts of cells and tissues by labeling them with glowing molecules, helping in the study of cell structure and movement, molecule behavior, and drug effects. To understand the...
Facile and scalable production of a fuel-cell nanocatalyst for the hydrogen economy
Feb 16, 2023 (Nanowerk News) A fuel cell is an electric power generator that is capable of producing electricity from hydrogen gas while discharging only water as a waste product. It is hoped that this highly efficient clean energy system will play a key role in the adoption of the...
Tsunami in a water glass
Feb 16, 2023 (Nanowerk News) So-called hydrated electrons play a major role in many physical, chemical and biological processes. They are not bound to an atom or molecule and are free in the solution. Since they are only ever created as an intermediate product, they are extremely short-lived. The team...
Quantum geometry found to be newest twist in superconductivity
Feb 16, 2023 (Nanowerk News) Scientists at The University of Texas at Dallas and their collaborators at The Ohio State University have identified a new mechanism that gives rise to superconductivity in a material in which the speed of electrons is nearly zero, potentially opening a pathway to the design...
New compound that withstands extreme heat and electricity could lead to next-generation energy storage devices
Feb 15, 2023 (Nanowerk News) Society’s growing demand for high-voltage electrical technologies – including pulsed power systems, cars and electrified aircraft, and renewable energy applications – requires a new generation of capacitors that store and deliver large amounts of energy under intense thermal and electrical conditions. Researchers at the Department...
Scientists find first observational evidence linking black holes to dark energy
Feb 15, 2023 (Nanowerk News) Searching through existing data spanning 9 billion years, a University of Michigan physicist and colleagues have uncovered the first evidence of “cosmological coupling”—a newly predicted phenomenon in Einstein’s theory of gravity, possible only when black holes are placed inside an evolving universe. Gregory Tarlé, U-M...
New approach for Majorana research in short nanowires
Feb 15, 2023 (Nanowerk News) Researchers and engineers from QuTech and Eindhoven University of Technology have created Majorana particles and measured their properties with great control. These Majoranas are so-called ‘poor man's Majoranas’ based on two quantum dots in a nanowire, which could be scaled up to a larger chain...
