The phrase "a car that runs on water (or air)" is an epitome that is often used to imagine sustainable future technologies for transportation. We can add to this list a car that could run on energy stored in nanocellulosic material from plants, thanks to Prof. Emily Cranston at McMaster University in Ontario, Canada.

Emily Cranston, an assistant professor of chemical engineering, and her colleagues recently demonstrated the fabrication of an energy storage device made of nanocellulose -an organic compound found in plants, bacteria, algae and trees. Cranston and her colleagues processed nanocellulose into a foam-like structure, which renders the lightweight characteristic of the new material. By trapping functional nanoparticles within this nanocellulosic structure, the team produced a capacitor with a higher powder density and faster charging abilities than conventional rechargeable batteries. More details on this work can be found in Advanced Materials.

Cranston's research focuses on developing sustainable nanocomposites, thin films with a focus on nanocellulosic materials, and studying surface forces and interfacial engineering. More about Prof. Cranston can be found on her website.

WiN also applauds McMaster University for recently giving all its women faculty a pay raise of $3000 (US) to close the gender gap in salary that they found in an analysis of their own institution. The gender salary gap in the US is much larger, $19,000, according to AAUP.
