Liquid phase production of graphene by exfoliation of graphite in surfactant/water solutions.
We have demonstrated a method to disperse and exfoliate graphite to give graphene suspended in water-surfactant solutions. Optical characterization of these suspensions allowed the partialExpand

Measurement of multicomponent solubility parameters for graphene facilitates solvent discovery.
We have measured the dispersibility of graphene in 40 solvents, with 28 of them previously unreported. We have shown that good solvents for graphene are characterized by a Hildebrand solubilityExpand

Nitrogen-doped graphene and its iron-based composite as efficient electrocatalysts for oxygen reduction reaction.
The high cost of platinum-based electrocatalysts for the oxygen reduction reaction (ORR) has hindered the practical application of fuel cells. Thanks to its unique chemical and structural properties,Expand

Flexible, transparent, conducting films of randomly stacked graphene from surfactant-stabilized, oxide-free graphene dispersions.
Graphite is exfoliated in water to give dispersions of mono- and few-layer graphene stabilized by surfactant. These dispersions can be used to form thin, disordered films of randomly stacked,Expand

Graphene nanoribbons as low band gap donor materials for organic photovoltaics: quantum chemical aided design.
Graphene nanoribbons (GNRs) are strips of graphene cut along a specific direction that feature peculiar electronic and optical properties owing to lateral confinement effects. We show here by meansExpand
