C sp2/sp3 hybridisations in carbon nanomaterials – XPS and (X)AES study
TL;DR: In this article, the shape of the C KLL (KVV) Auger spectrum provides a measure of C sp2/sp3 hybridisations, alternative to C 1s spectra fitting.
Journal ArticleDOI
Studies of heavy metal ion adsorption on chitosan/sulfydryl-functionalized graphene oxide composites.
TL;DR: It was found that the CS/GO-SH has potential applications in fields of adsorptive materials due to its superiority of the chemical characteristic and the specific surface area.
