SEM: TiO2 nanoparticles coated with carbon
By Christopher Johnson and Vilas G. Pol
These are nanoparticles coated with carbon (like a Tootsie-Roll Pop), which scientists are testing as a possible ingredient for better batteries. These studies often reach into the nano-level as researchers try to understand activity at the atomic scale in order to custom-design new materials for batteries.
