The determination of the electron-electron interaction constant λc in carbon nanostructures based on curved graphene layers, was illustrated. Variable range hopping and nonmonotonous change in electrical conduction with nanodiamond graphitization were discovered in onion-like carbon. The charge carrier concentration was determined from negative magnetoresistance data and was found to be highest in a sample with the most defects at the initial stage of graphitization. The results show that graphene layer distortion in skeleton carbon nanostructures results to a change in λc.
