WebMay 13, 1998 · Graphite oxide (GO) and its derivatives have been studied using 13C and 1H NMR. NMR spectra of GO derivatives confirm the assignment of the 70 ppm line to C−OH groups and allow us to propose a new structural model for GO. Thus we assign the 60 ppm line to epoxide groups (1,2-ethers) and not to 1,3-ethers, as suggested earlier, … WebMay 6, 2024 · Despite the potential applications in energy storage and conversion systems such as Li–oxygen batteries and fuel cells, the nature and distribution of doped nitrogen … WebOct 3, 2024 · NMR detects room temperature magnetic-like effects in graphene-associated organic molecular assemblies, when shielding from the orbital diamagnetism of the … greatest hits 1 queen
