Jan 20, 2023 (Nanowerk News) Scientists have advanced in discovering how to use ripples in space-time known as gravitational waves to peer back to the beginning of everything we know. The researchers say they can better understand the state of the cosmos shortly after the Big Bang by learning how...
Incorporation of water molecules into layered materials impacts ion storage capability
Jan 20, 2023 (Nanowerk News) Investigating the interplay between the structure of water molecules that have been incorporated into layered materials such as clays and the configuration of ions in such materials has long proved a great experimental challenge. But researchers have now used a technique elsewhere commonly used to...
Physical effect also valid in the quantum world
Jan 20, 2023 (Nanowerk News) Physicists at the University of Bonn have experimentally proven that an important theorem of statistical physics applies to so-called "Bose-Einstein condensates." Their results now make it possible to measure certain properties of the quantum “superparticles” and deduce system characteristics that would otherwise be difficult to...
New insights into the utilization of nanotechnology-based drugs
Jan 20, 2023 (Nanowerk News) Novel drugs, such as vaccines against covid-19, among others, are based on drug transport using nanoparticles. Whether this drug transport is negatively influenced by an accumulation of blood proteins on the nanoparticle’s surface was not clarified for a long time. Scientists at the Max Planck...
Squid tissues and chemistry combine for versatile hydrogels
Jan 20, 2023 (Nanowerk News) Researchers at Hokkaido University in Japan have combined natural squid tissues with synthetic polymers to develop a strong and versatile hydrogel that mimics many of the unique properties of biological tissues. Hydrogels are polymer networks containing large quantities of water, and are being explored for...
Nanoscopic tool assesses alternative COVID-19 prevention
Jan 20, 2023 (Nanowerk News) Researchers at Kanazawa University report in Nano Letters ("Nanoscopic Assessment of Anti-SARS-CoV‑2 Spike Neutralizing Antibody Using High-Speed AFM") how high-speed atomic force microscopy can be used to assess the effectivity of spike-neutralizing antibodies for preventing COVID-19. The use of such antibodies offers a promising alternative...
Novel fluorescent compound could massively boost the efficiency of device screens
Jan 19, 2023 (Nanowerk News) Increases in the energy efficiency of organic light-emitting diodes (OLEDs) are usually incremental, but the discovery of a rule-avoiding fluorescent organic compound by RIKEN chemists promises to dramatically boost display efficiencies (Nature, "Delayed fluorescence from inverted singlet and triplet excited states"). The displays of mobile...
Approaching the terahertz regime
Jan 19, 2023 (Nanowerk News) A class of nonvolatile memory devices, called MRAM, based on quantum magnetic materials, can offer a thousandfold performance beyond current state-of-the-art memory devices. The materials known as antiferromagnets were previously demonstrated to store stable memory states, but were difficult to read from. This new study...
Sensing odor molecules on graphene surface layered with self-assembled peptides
Jan 19, 2023 (Nanowerk News) Graphene-based olfactory sensors that can detect odor molecules based on the design of peptide sequences were recently demonstrated by researchers at Tokyo Tech. The findings indicated that graphene field-effect transistors (GFETs) functionalized with designable peptides can be used to develop electronic devices that mimic olfactory...
