Hot electrons do the impossible in catalytic chemistry
Shape-changing liquid metal antenna could lead to responsive electronic devices
Chemists use high speed camera to fully explain high school explosion demonstration
Microscopy reveals how atom-high steps impede oxidation of metal surfaces
Rust never sleeps. Whether a reference to the 1979 Neil Young album or a product designed to protect metal surfaces, the phrase invokes the idea that corrosion from oxidation—the more general chemical name ...
Scientists control surface tension to manipulate liquid metals (w/ Video)
Researchers from North Carolina State University have developed a technique for controlling the surface tension of liquid metals by applying very low voltages, opening the door to a new generation of reconfigurable ...
Researchers time plasmon-generated electrons moving from nanorods to graphene
(Phys.org) —Plasmonic nanoparticles developed at Rice University are becoming known for their ability to turn light into heat, but how to use them to generate electricity is not nearly as well understood.
Graphene 'onion rings' have delicious potential
Concentric hexagons of graphene grown in a furnace at Rice University represent the first time anyone has synthesized graphene nanoribbons on metal from the bottom up—atom by atom.
A quantum simulator for magnetic materials
Physicists understand perfectly well why a fridge magnet sticks to certain metallic surfaces. But there are more exotic forms of magnetism whose properties remain unclear, despite decades of intense research. ...
Physicists find right (and left) solution for on-chip optics
(Phys.org) —A Harvard-led team of researchers has created a new type of nanoscale device that converts an optical signal into waves that travel along a metal surface. Significantly, the device can recognize ...
Scientists spin photons to send light in one direction
(Phys.org) —Researchers at King's College London have achieved previously unseen levels of control over the travelling direction of electromagnetic waves in waveguides. Their ground-breaking results could ...
Another tiny miracle: Graphene oxide soaks up radioactive waste
(Phys.org)—Graphene oxide has a remarkable ability to quickly remove radioactive material from contaminated water, researchers at Rice University and Lomonosov Moscow State University have found.
Nanofibers clean sulfur from fuel
(Phys.org)—Sulfur compounds in petroleum fuels have met their nano-structured match. University of Illinois researchers developed mats of metal oxide nanofibers that scrub sulfur from petroleum-based fuels ...
James' bond: A graphene / nanotube hybrid
