Thermal and Structural Characterizations of Individual Single-, Double-, and Multi-Walled Carbon Nanotubes November 23, 2009

AUSTIN, Texas – Researchers at the Texas Materials Institute report thermal conductance and structural characterization of individual carbon nanotubes (CNTs). Pettes and Shi obtained thermal conductance measurements for single nanotubes grown between two suspended microthermometers using chemical vapor deposition. Using transmission electron microscopy, scanning electron microscopy, and nanoarea electron diffraction, they determined the structure and dimensions of the nanotube within each microdevice. more...

Engineers develop method to disperse chemically modified graphene in organic solvents - March 31, 2009

AUSTIN, Texas – A method for creating dispersed and chemically modified graphene sheets in a wide variety of organic solvents has been developed by a University of Texas at Austin engineering team led by Professor Rod Ruoff, opening the door to use graphene in a host of important materials and applications such as conductive films, polymer composites, ultracapacitors, batteries, paints, inks and plastic electronics. more...

Dr. Graeme Henkelman of Chemistry is “Speeding Up Nano-Discovery”

Lately, there’s been a lot of excitement about nanotechnology,” Graeme Henkelman, professor of chemistry at The University of Texas at Austin, said, with characteristic earnestness. “People have realized that as you make things small, particularly on the nanoscale, there are some properties that come out that are completely different than the bulk materials.”more...

Prof. Ruoff's 4 nanostructure papers in Carbon, Nano Letters, and Chemistry of Materials.

These papers are about the chemical analysis of graphene oxide films after heat and chemical treatments by X-ray photoelectron and Micro-Raman spectroscopy, achieving tunable electrical Conductivity of individual graphene oxide sheets Reduced at "low" temperatures, the creation of aqueous suspensions of chemically modified garphene sheets and their characterization, and in collaboration with Professors Michael Trenary and Allan Nichols, and graduate student Panchatapa Jash, all of the University of Illinois-Chicago, on the synthesis and Characterization of single-crystal strontium hexaboride nanowires.

Team takes first atomic-scale compositional images of fuel-cell nanoparticles

AUSTIN, Texas -- In a step toward developing better fuel cells for electric cars and more, The University of Texas at Austin, together with MIT and the Oak Ridge National Laboratory, have taken the first images of individual atoms on and near the surface of nanoparticles key to the eco-friendly energy conversion devices.

New Graphene-Based Material Clarifies Graphite Oxide Chemistry - September 25, 2008

AUSTIN, Texas — A new "graphene-based" material that helps solve the structure of graphite oxide and could lead to other potential discoveries of the one-atom thick substance called graphene, which has applications in nanoelectronics, energy storage and production, and transportation such as airplanes and cars, has been created by researchers at The University of Texas at Austin.
