NREL reveals thermoelectric potential for tailored semiconducting carbon nanotubes

Green Car Congress

A finely tuned carbon nanotube thin film has the potential to act as a thermoelectric power generator that captures and uses waste heat, according to researchers at the Energy Department’s National Renewable Energy Laboratory (NREL). Carbon nanotubes, which are organic, are lighter and more flexible. —Andrew Ferguson.

New thermoplastic-graphene nanoribbon composite could offer lighter, more effective natural gas storage for vehicles

Green Car Congress

A new composite material created at Rice University is nearly impervious to gas and may lead to lighter and more efficient storage of compressed natural gas for vehicles. Most work to date has focused upon the filler’s aspect ratio or configuration within the polymer matrix affects gas barrier properties. Image by Changsheng Xiang.

Roadmap shows how to improve lignocellulosic biofuel biorefining with high-value products from isolated lignin

Green Car Congress

Potential high-value products from isolated lignin include low-cost carbon fiber, engineering plastics and thermoplastic elastomers, polymeric foams and membranes, and a variety of fuels and chemicals—all currently sourced from petroleum. Each product stream, however, has its own distinct challenges. Ragauskas et al. Click to enlarge.

Researchers use DNA to stabilize sulfur cathode for high-performance Li-sulfur batteries

Green Car Congress

A team from the China University of Geosciences has taken a novel approach to stabilizing Lithium-sulfur batteries by functionalizing the carbon-sulfur cathode with DNA. CMK-3 carbon was then ultrasonically dispersed into the solution. —Li et al.

Researchers use crumpled graphene balls to avoid dendrite growth on Li-metal anodes

Green Car Congress

Researchers at Northwestern University and Tianjin University now report an effective approach to avoiding dendrite growth on Li-metal anodes by using a scaffold based on crumpled paper ball-like graphene (CGB) particles. Porous carbon nanostructures, including graphene-based materials, are attractive lightweight Li host materials.
