It seemed that the only way ps[4], which are the two novel members of the carbon nanostructure family. The ESR literature on graphene isA natural expectation is that ESR can be applied for single-wall carbon nanotubes (SWCNTs) [3] and graphene itinerant (i.e. the all.

KGaA, Weinheim 1 Introduction Electron spin resonance (ESR) has proven to be an important method in identifying the ground state of strongly correlated electron...
