Journal ArticleDOI
Improved Synthesis of Graphene Oxide
Daniela C. Marcano,Dmitry V. Kosynkin,Jacob M. Berlin,Alexander Sinitskii,Zhengzong Sun,Alexander S. Slesarev,Lawrence B. Alemany,Wei Lu,James M. Tour +8 more
TL;DR: An improved method for the preparation of graphene oxide (GO) is described, finding that excluding the NaNO(3), increasing the amount of KMnO(4), and performing the reaction in a 9:1 mixture of H(2)SO(4)/H(3)PO(4) improves the efficiency of the oxidation process.
Journal ArticleDOI
New insights into the structure and reduction of graphite oxide
TL;DR: This work has devised a complete reduction process through chemical conversion by sodium borohydride and sulfuric acid treatment, followed by thermal annealing that is particularly effective in the restoration of the π-conjugated structure, and leads to highly soluble and conductive graphene materials.
Journal ArticleDOI
Graphene quantum dots derived from carbon fibers.

TL;DR: It is reported that during the acid treatment and chemical exfoliation of traditional pitch-based carbon fibers, that are both cheap and commercially available, the stacked graphitic submicrometer domains of the fibers are easily broken down, leading to the creation of GQDs with different size distribution in scalable amounts.
Journal ArticleDOI
C60 in water: nanocrystal formation and microbial response.
John D. Fortner,Delina Y. Lyon,Christie M. Sayes,Adina M. Boyd,J C Falkner,E M Hotze,Lawrence B. Alemany,Yizhi Jane Tao,W Guo,Kevin D. Ausman,Vicki L. Colvin,Joseph B. Hughes +11 more
TL;DR: The environmental fate, distribution, and biological risk associated with this important class of engineered nanomaterials will require a model that addresses not only the properties of bulk C60 but also that of the aggregate form generated in aqueous media.
Journal ArticleDOI
Graphene oxide. Origin of acidity, its instability in water, and a new dynamic structural model.
TL;DR: An unconventional view of GO chemistry is proposed and the corresponding "dynamic structural model" (DSM) is developed, which provides an explanation for the acidity of GO aqueous solutions and accounts for most of the known spectroscopic and experimental data.
