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...

Fine Patterns That Combine Single-atom-thick Graphene And Boron Nitride Created By Researchers
2013-01-28 08:00:21

Rice University Rice University scientists have taken an important step toward the creation of two-dimensional electronics with a process to make patterns in atom-thick layers that combine a conductor and an insulator. The materials at play — graphene and hexagonal boron nitride — have been merged into sheets and built into a variety of patterns at nanoscale dimensions. Rice introduced a technique to stitch the identically structured materials together nearly three years...

Rice researchers develop paintable battery
2012-06-29 05:30:54

[ Watch the Video ] Michael Harper for redOrbit.com — Your Universe Online Researchers at Rice University in Houston, Texas have put their minds together to create an incredibly thin battery. So small, in fact, if can be painted on the surface of whatever it´s meant to power. This rechargeable lithium-ion battery is applied in layers, recreating the components of a traditional battery. Rice scientist Pulickel Ajayan helped to create the sprayable battery and posted the...

Researchers at Rice University and Penn State University have discovered that adding a dash of boron to carbon while creating nanotubes turns them into solid, spongy, reusable blocks that have an astounding ability to absorb oil spilled in water. That´s one of a range of potential innovations for the material created in a single step. The team found for the first time that boron puts kinks and elbows into the nanotubes as they grow and promotes the formation of covalent bonds, which...

Rice University lab uses nanoparticles to increase thermal properties of transformer oil Rice University scientists have created a nano-infused oil that could greatly enhance the ability of devices as large as electrical transformers and as small as microelectronic components to shed excess heat. Research in the lab of Rice materials scientist Pulickel Ajayan, which appears in the American Chemical Society journal ACS Nano, could raise the efficiency of such transformer oils by as much...

Engineers at Rensselaer Polytechnic Institute and Rice University Discover How the Extreme Thinness of Graphene Enables Near-Perfect Wetting Transparency Graphene is the thinnest material known to science. The nanomaterial is so thin, in fact, water often doesn´t even know it´s there. Engineering researchers at Rensselaer Polytechnic Institute and Rice University coated pieces of gold, copper, and silicon with a single layer of graphene, and then placed a drop of water on the...

Rice University-led team creates tiny materials in bulk from carbon fiber A Rice University laboratory has found a way to turn common carbon fiber into graphene quantum dots, tiny specks of matter with properties expected to prove useful in electronic, optical and biomedical applications. The Rice lab of materials scientist Pulickel Ajayan, in collaboration with colleagues in China, India, Japan and the Texas Medical Center, discovered a one-step chemical process that is markedly...

Image 1 - Nanocables Light The Way To The Future

  Rice researchers power line-voltage light bulb with nanotube wire Cables made of carbon nanotubes are inching toward electrical conductivities seen in metal wires, and that may light up interest among a range of industries, according to Rice University researchers. A Rice lab made such a cable from double-walled carbon nanotubes and powered a fluorescent light bulb at standard line voltage -- a true test of the novel material's ability to stake a claim in energy systems of the...

Hybrid energy storage device is as small as it can possibly get The world at large runs on lithium ion batteries. New research at Rice University shows that tiny worlds may soon do the same. The Rice lab of Professor Pulickel Ajayan has packed an entire lithium ion energy storage device into a single nanowire, as reported this month in the American Chemical Society journal Nano Letters. The researchers believe their creation is as small as such devices can possibly get, and could be valuable...

Researchers at Rice University have created a synthetic material that gets stronger from repeated stress much like the body strengthens bones and muscles after repeated workouts. Work by the Rice lab of Pulickel Ajayan, professor in mechanical engineering and materials science and of chemistry, shows the potential of stiffening polymer-based nanocomposites with carbon nanotube fillers. The team reported its discovery this month in the journal ACS Nano. The trick, it seems, lies in the...
