Small, fuel efficient vehicle engines in the 1.0-liter-to-1.9-liter displacement range already make up the lion's share of the global vehicle fleet, and that number is going to get larger. A WardsAuto/AutomotiveCompass global powertrain forecast says the small engines will climb from 49 percent this year to over half next year, and then 52 percent by 2020. While the percentage change isn't much, the volume is huge: 15 million more vehicles.
In work recently published in the Journal of Applied Physics, a University of Technology Sydney (UTS) team led by professor Guoxiu Wang presented reproducible test results showing that graphene paper has the potential to revolutionize the automotive industry. How? Well, researchers at UTS have milled raw graphite by purifying and filtering it with chemicals to reshape and reform it into graphene nanosheets. We should explain.
