    Broad Family of Carbon Nanoallotropes: Classification, Chemistry, and Applications of Fullerenes, Carbon Dots, Nanotubes, Graphene, Nanodiamonds, and Combined Superstructures
    (Washington, DC : ACS Publ., 2015) Georgakilas, Vasilios; Perman, Jason A.; Tucek, Jiri; Zboril, Radek
    Classification, chemistry, and applications of fullerenes, carbon dots, nanotubes, graphene, nanodiamonds, and combined superstructures of a range of carbon nanoallotropes are investigated. The investigations also cover superstructures consisting of combinations of carbon nanoallotropes such as fullerene aggregates, CNTs or graphene thin films, fibers, membranes, and aerogels in addition to describing individual carbon nanoallotropes. The issue of chemical modification of carbon nanoallotropes with division into several sections based on the origins of the chemical reactivity in each case is also investigated.

    Functional Nanosheet Synthons by Covalent Modification of Transition-Metal Dichalcogenides
    (Washington, DC : American Chemical Society, 2017) Presolski, Stanislav; Wang, Lu; Loo, Adeline Huiling; Ambrosi, Adriano; Lazar, Petr; Ranc, Václav; Otyepka, Michal; Zboril, Radek; Tomanec, Ondřej; Ugolotti, Juri; Sofer, Zdeněk; Pumera, Martin
    We report on the facile preparation of versatile MoS2-thiobarbituric acid conjugates, which, in addition to excellent electrochemical behavior, can serve as nanosheet platforms for further functionalization in a multitude of applications. We show that chemically exfoliated MoS2 was extensively modified with up to 50% surface coverage, while maintaining its metallic character, and that the strategy can be extended to MoSe2, WS2, and WSe2. The covalent functionalization endowed the materials not only with good aqueous dispersibility, but also with improved hydrogen evolution reaction (HER) activity, as well as promise in the oxidative detection of DNA nucleobases in solution.
