Roots of superfluorescent bursts from quantum wells
Spontaneous bursts of light from a solid block illuminate the unusual way interacting quantum particles behave when they are driven far from equilibrium. The discovery by Rice University scientists of a way to trigger these flashes may lead to new telecommunications equipment and other ...
Gold-palladium nanocatalysts set new mark for breakdown of nitrites
Chemical engineers at Rice University have found a new catalyst that can rapidly break down nitrites, a common and harmful contaminant in drinking water that often results from overuse of agricultural fertilizers. Nitrites and their more abundant cousins, nitrates, are inorganic compounds ...
Rice U. theorists calculate atom-thick carbyne chains may be strongest material ever
Carbyne will be the strongest of a new class of microscopic materials if and when anyone can make it in bulk. If they do, they'll find carbyne nanorods or nanoropes have a host of remarkable and useful properties, as described in a new paper by Rice University theoretical physicist Boris ...
A discovery at Rice University aims to make vehicles that run on compressed natural gas more practical. It might also prolong the shelf life of bottled beer and soda. The Rice lab of chemist James Tour has enhanced a polymer material to make it far more impermeable to pressurized gas and far ...
Rice University lab traps metallic compounds to sniff out signs of hazardous solvents
Rice University scientists took a lesson from craftsmen of old to assemble microscopic compounds that warn of the presence of dangerous fumes from solvents. The researchers combined a common mineral, zeolite, with a metallic compound based on rhenium to make an "artificial nose" that can ...
Nano-thin films of hexagonal boron nitride protect materials from oxidizing
Atomically thin sheets of hexagonal boron nitride (h-BN) have the handy benefit of protecting what’s underneath from oxidizing even at very high temperatures, Rice University researchers have discovered. One or several layers of the material sometimes called “white graphene” keep materials ...
Rice University lab creates energy storage that may find use in oil discovery, space, military applications
Clay, an abundant and cheap natural material, is a key ingredient in a supercapacitor that can operate at very high temperatures, according to Rice University researchers who have developed such a device. The Rice group of materials scientist Pulickel Ajayan reported in Scientific Reports, ...
A Rice University laboratory has improved upon its ability to determine molecular structures in three dimensions in ways that challenge long-used standards. By measuring the vibrations between atoms using femtosecond-long laser pulses, the Rice lab of chemist Junrong Zheng is able to discern ...
New material created at Rice University with graphene oxide flakes
Large flakes of graphene oxide are the essential ingredient in a new recipe for robust carbon fiber created at Rice University. The fiber spun at Rice is unique for the strength of its knots. Most fibers are most likely to snap under tension at the knot, but Rice's fiber demonstrates what the ...
Researchers at Rice University have come up with a new way to boost the efficiency of the ubiquitous lithium ion (LI) battery by employing ribbons of graphene that start as carbon nanotubes. Proof-of-concept anodes -- the part of the battery that stores lithium ions -- built with graphene ...
