Researchers use chicken poop to dope graphene to make a point
(PHYSorg.com Nanotechnology)

A trio of researchers, two from the University of Chemistry and Technology, Praha 6, the other the University of Toronto, has demonstrated that chicken feces can be used to make graphene a better catalyst. In their paper published in the journal ACS Nano, Lu Wang, Zdenek Sofer and Martin Pumera argue that researchers churning out papers describing newly found dopants for graphene are not contributing to understanding graphene`s electrocatalytic abilities.
