Riding the quantum Kelvin wave
Jan 27, 2025 (Nanowerk News) Lord Kelvin theorized in 1880 that stimulating a thin vortex line would produce a helical deformation, later known as a Kelvin wave. While these waves have been observed in classical fluids like water and air, their existence in quantum fluids has remained largely theoretical due...
Team uses achiral hard banana-shaped particles to assemble skyrmions and blue phases
Jan 27, 2025 (Nanowerk News) A research team has discovered that achiral hard banana-shaped particles can spontaneously form exotic structures like skyrmions and blue phase III phases. Skyrmions are tiny vortex-like structures found in various condensed-matter systems, such as helical ferromagnets and liquid crystals. Blue phase III is an amorphous...
High-brilliance radiation quickly finds the best composition for half-metal alloys
Jan 27, 2025 (Nanowerk News) Half-metals are unique magnetic compounds that have been attracting interest in the developments of mass-storage technologies. Some of the materials in the family of Heusler alloys were predicted to have a half-metallic nature, but their half-metallic electronic structure varies with their composition ratio and atomic...
Atomic coating prevents bacterial growth on surgical sutures
Jan 27, 2025 (Nanowerk Spotlight) Every surgical procedure, from routine appendectomies to complex organ transplants, relies on a technology that has remained fundamentally unchanged for thousands of years: the surgical suture. These threads that bind wounds closed serve as a critical tool in healing but can also become a dangerous...
Machine learning and nano-3D printing create breakthrough nano-architected materials
Jan 25, 2025 (Nanowerk News) Researchers at the University of Toronto’s Faculty of Applied Science & Engineering have used machine learning to design nano-architected materials that have the strength of carbon steel but the lightness of Styrofoam. In a new paper published in Advanced Materials ("Ultrahigh Specific Strength by Bayesian...
Kirigami hydrogels rise from cellulose film
Jan 24, 2025 (Nanowerk News) Hydrogels have a network of water-attracting (hydrophilic) molecules, allowing their structure to swell substantially when exposed to water. Researchers Daisuke Nakagawa and Itsuo Hanasaki from Tokyo University of Agriculture and Technology (TUAT) are looking into new options for making “kirigami hydrogels” that swell into complex...
engineering the first semimetallic Weyl quantum crystal
Jan 24, 2025 (Nanowerk News) An international team of researchers led by the Strong Correlation Quantum Transport Laboratory of the RIKEN Center for Emergent Matter Science (CEMS) has demonstrated, in a world’s first, an ideal Weyl semimetal, marking a breakthrough in a decade-old problem of quantum materials. Weyl fermions arise...
Physicists discover – and explain
Jan 24, 2025 (Nanowerk News) MIT physicists have created a new ultrathin, two-dimensional material with unusual magnetic properties that initially surprised the researchers before they went on to solve the complicated puzzle behind those properties’ emergence. As a result, the work introduces a new platform for studying how materials behave...
New atom-based thermometer measures temperature more accurately
Jan 24, 2025 (Nanowerk News) Scientists at the National Institute of Standards and Technology (NIST) have created a new thermometer using atoms boosted to such high energy levels that they are a thousand times larger than normal. By monitoring how these giant “Rydberg” atoms interact with heat in their environment,...
