Porous Material Polymerizes Carbon Dioxide At Natural Gas Wellheads
2014-06-04 03:47:25

By Mike Williams, Rice University Rice University scientists have created an Earth-friendly way to separate carbon dioxide from natural gas at wellheads. A porous material invented by the Rice lab of chemist James Tour sequesters carbon dioxide, a greenhouse gas, at ambient temperature with pressure provided by the wellhead and lets it go once the pressure is released. The material shows promise to replace more costly and energy-intensive processes. Results from the research appear...

Rice University lab makes hybrid nanotube-graphene material that promises to simplify manufacturing Carbon nanotubes are reinforcing bars that make two-dimensional graphene much easier to handle in a new hybrid material grown by researchers at Rice University. The Rice lab of chemist James Tour set nanotubes into graphene in a way that not only mimics how steel rebar is used in concrete but also preserves and even improves the electrical and mechanical qualities of both. The...

Scientists: Coal Is Better, Cheaper For Making Graphene Quantum Dots
2013-12-06 16:55:31

Brett Smith for redOrbit.com – Your Universe Online A team of scientists from Rice University has found a way to use coal as a source of graphene quantum dots (GQD), tiny fluorescent particles that could be used in medical imaging and photovoltaic applications – according to a new report in Nature Communications. The use of coal to make GQDs would be much cheaper than conventional means, which are expensive and only produce small quantities. “We wanted to see what’s there in...

Mix Of Nanoribbons And Polymer Has Potential For Cars, Soda And Beer
2013-10-11 10:53:53

Rice University 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 lighter than the metal in tanks now used to contain the gas. The combination could be a boon for an auto industry under pressure to market consumer cars that use cheaper natural...

Embedded Diodes Boost Rice University Invention's Potential As Robust, Roomy Memory
2013-07-09 14:58:25

Rice University A Rice University laboratory pioneering memory devices that use cheap, plentiful silicon oxide to store data has pushed them a step further with chips that show the technology's practicality. The team led by Rice chemist James Tour has built a 1-kilobit rewritable silicon oxide device with diodes that eliminate data-corrupting crosstalk. A paper on the new work appears this week in the journal Advanced Materials. With gigabytes of flash memory becoming steadily...

Rice University lab combines graphene nanoribbons with tin oxide for improved anodes 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 nanoribbons (GNRs) and tin oxide showed an initial capacity better than the theoretical capacity of tin...

Rice University develops indium-free transparent, flexible electrodes Flexible, transparent electronics are closer to reality with the creation of graphene-based electrodes at Rice University. The lab of Rice chemist James Tour lab has created thin films that could revolutionize touch-screen displays, solar panels and LED lighting. The research was reported in the online edition of ACS Nano. Flexible, see-through video screens may be the "killer app" that finally puts graphene -- the highly...

Rice University lab finds table sugar, metallic sheets produce pristine graphene in one step Future computers may run a little sweeter, thanks to a refinement in the manufacture of graphene at Rice University. Rice researchers have learned to make pristine sheets of graphene, the one-atom-thick form of carbon, from plain table sugar and other carbon-based substances. They do so in a one-step process at temperatures low enough to make graphene easy to manufacture. The lab of Rice chemist James...

Rice University think tank will strategize on environmentally sound policies on oil, gas, coal Rice University has created a Green Carbon Center to bring the benefits offered by oil, gas, coal, wind, solar, geothermal, biomass and other energy sources together in a way that will not only help ensure the world's energy future but also provide a means to recycle carbon dioxide into useful products. Whether or not one believes in anthropogenic climate change, the fact is humans are throwing away...
