TL;DR: N and S codoping of graphene is realized by a novel approach: covalent functionalization of graphene oxide using 2-aminothiophenol as a source of both N and S followed by thermal treatment.

TL;DR: By introducing the molecular orbital concept, the dominant fluorescence was found to originate from the electronic transitions among/between the non-oxidized carbon regions and the boundary of oxidized carbon atom regions, where all three kinds of functionalized groups C-O, C = O and O = C-OH were participating.

TL;DR: A simple solvothermal method to synthesize a series of MoS2 nanosheets@nitrogen-doped graphene composites is developed, demonstrating the significance in surface-controlled pseudocapacitance contribution at the high rate and offering some meaningful preparation and investigation experiences for designing electrode materials for commercial sodium-ion batteries with favorable performance.

TL;DR: In this paper, a smart strategy to convert used disposable bamboo chopsticks into uniform carbon fibers for anodes of Li-ion batteries was proposed, which can be further upgraded by growing nanostructured metal oxides (like MnO2) firmly on each fiber scaffold to form a synergetic core-shell electrode architecture.

TL;DR: The present encapsulation strategy and understanding of hydroxide working mechanisms may advance progress on the development of lithium/sulfur cells for practical use.
