Advancements in meta-holographic display enable ultraviolet domain holograms

Jun 14, 2023 (Nanowerk News) The term meta means a concept of transcendence or surpassing, and when applied to materials, metamaterials encompass artificially engineered substances that exhibit properties not naturally found in the environment. Metasurfaces, characterized by their thinness and lightness, have garnered considerable interest as a potential component for...

Shining potential of missing atoms

Jun 14, 2023 (Nanowerk News) Single photons have applications in quantum computation, information networks, and sensors, and these can be emitted by defects in the atomically thin insulator hexagonal boron nitride (hBN). Missing nitrogen atoms have been suggested to be the atomic structure responsible for this activity, but it is...

Weighing a quasar’s galaxy with precision

Jun 13, 2023 (Nanowerk News) A team of researchers from EPFL have found a way to use the phenomenon of strong gravitational lensing to determine with precision – about 3 times more precise than any other technique – the mass of a galaxy containing a quasar, as well as their...

Treadmill for microswimmers allows closer look at behavior

Jun 13, 2023 (Nanowerk News) A team from the McKelvey School of Engineering at Washington University in St. Louis and Massachusetts Institute of Technology has created an acoustic microfluidic method that offers new opportunities to conduct experiments with swimming cells and microorganisms. “The cells that our collaborators study are powerful...

A baking soda solution for clean hydrogen storage

Jun 13, 2023 (Nanowerk News) In a world of continuously warmer temperatures, a growing consensus demands that energy sources have zero, or next-to-zero, carbon emissions. That means growing beyond coal, oil, and natural gas by getting more energy from renewable sources. One of the most promising renewable energy carriers is...

New diagnostic platform uses nanotechnology and machine learning to identify infectious diseases quickly

Jun 12, 2023 (Nanowerk News) Infectious diseases and respiratory infections in particular are a leading cause of global mortality. As such, there is an urgent need for rapid, large-scale diagnostic tools that can detect these diseases early, something which doesn’t currently exist. To address these problems, McGill University Professor of...
