Feb 16, 2023 (Nanowerk News) Rice University scientists have figured out a way to engineer wood to trap carbon dioxide through a potentially scalable, energy-efficient process that also makes the material stronger for use in construction. Structural materials like steel or cement come at a high cost both in dollars...
A more efficient method to pull carbon dioxide out of seawater
Feb 16, 2023 (Nanowerk News) As carbon dioxide continues to build up in the Earth’s atmosphere, research teams around the world have spent years seeking ways to remove the gas efficiently from the air. Meanwhile, the world’s number one “sink” for carbon dioxide from the atmosphere is the ocean, which...
New antibiotic cures superbugs without bacterial resistance
Feb 16, 2023 (Nanowerk News) In a potential game changer for the treatment of superbugs, a new class of antibiotics was developed that cured mice infected with bacteria deemed nearly “untreatable” in humans — and resistance to the drug was virtually undetectable. Developed by a research team of UC Santa...
Nanoparticles perform ultralong distance communication
Feb 16, 2023 (Nanowerk News) Northwestern University chemists have designed a new photonic lattice with properties never before seen in nature. In solid materials, atoms must be equally spaced apart and close enough together to interact effectively. Now, new architectures based on stacked lattices of nanoparticles show interactions across unprecedentedly...
Chiral phonons create spin current without needing magnetic materials
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...
