  • Buckyballs could make carbon capture better

    9th Dec 2014

    The ever-useful buckminsterfullerene, or buckyball, has a new potential application: carbon capture.
    Researchers at Rice University in Texas used buckyballs (carbon-60 molecules, technically) as a “cross-linker” with polyethyleneimine (PEI), and produced a compound that binds carbon dioxide very well, avoids binding methane, and can be used at lower temperatures than other materials.

  • Buckyballs could make carbon capture better

    IEEE Spectrum , 9th Dec 2014

    PEI-C60 captures carbon better than materials known as metal organic frameworks (MOFs), which are nanoporous materials considered among the most promising for trapping CO2.

  • Rice team fine-tunes sorbents for carbon capture, methane selectivity

    Green Car Congress

    Natural gas producers want to draw all the methane they can from a well while sequestering as much carbon dioxide as possible; filters optimize either carbon capture or methane flow, but no single filter will do both. New work form Rice University now shows that subtle adjustments in the manufacture of a polymer-based carbon sorbent make it the best-known material either for capturing the greenhouse gas or balancing carbon capture with methane selectivity, according to Rice chemist Andrew Barron.

  • Touchy nanotubes work better when clean

    Nanotechnology Now

    Rice chemist Andrew Barron, also a professor at Swansea in the United Kingdom, and his team have figured out how to get nanotubes clean and in the process discovered why the electrical properties of nanotubes have historically been so difficult to measure.
