From Smart Planet:
Two papers published this week in ACS Nano detail the two ends of graphene’s life cycle. While many theories exist on how to best make graphene and graphene oxide (GO) in bulk, one paper demonstrates how to do so without emitting toxic gas.
The other study addresses how graphene will decompose in the environment. The research finds the almost ubiquitous Shewanella bacteria capable of breaking down GO into graphene. Stacks of graphene, which are single-atom carbon layers, become graphite, which is considered ecologically benign.
This is good news as graphene’s potential is enormous.
