A multi-element high-entropy alloy not only tests out as one of the toughest materials on record, but, unlike most materials, the toughness as well as the strength and ductility of this alloy actually improves at cryogenic temperatures.
Researchers have, for the first time, provided direct evidence of a water-mediated reaction mechanism for the catalytic oxidation of carbon monoxide. The work used gold nanoparticles and titanium dioxide as a catalyst to speed the process and determined that water serves as a co-catalyst for the reaction that transforms carbon monoxide into carbon dioxide.
A new combination of materials can efficiently guide electricity and light along the same tiny wire, a finding that could be a step towards building computer chips capable of transporting digital information at the speed of light.
Research shows that a type of modified titania, or titanium dioxide, holds promise as an electrical insulator for superconducting magnets, allowing heat to dissipate while preserving the electrical paths along which current flows.
A novel protein nanoparticle has shown to be effective at getting the immune system to attack the most lethal species of malaria parasite, Plasmodium falciparum, after it enters the body and before it has a chance to hide and aggressively spread.
Researchers in Japan have engineered a membrane with advanced features capable of removing harmful greenhouse gases from the atmosphere. Their findings may one day contribute to lower greenhouse gas emissions and cleaner skies.
A collection of the state-of-the-art reviews written by the leading researchers in the areas of nanoscale mechanics, molecular dynamics, nanoscale modeling of nanocomposites and mechanics of carbon nanotubes.
Scientists have developed a method that allows the prediction of the current density-voltage curve of a photovoltaic device. This new method uses a common measurement technique (impedance spectroscopy) that is affordable, widely available to manufacturers, and relatively easy to perform.
Scientists have discovered a new way to control light. Light can be guided along the surface of a metal via a surface plasmon polariton phenomenon. When light guided along the surface of one metal encounters a different metal surface, the new type of plasmon called an 'inhomogeneous surface plasmon polariton' results that has controlled confinement properties.
