High-yield production of graphene by liquid-phase exfoliation of graphite.
Fully exploiting the properties of graphene will require a method for the mass production of this remarkable material. Two main routes are possible: large-scale growth or large-scale exfoliation.… Expand

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 partial… Expand

Two-Dimensional Nanosheets Produced by Liquid Exfoliation of Layered Materials
Layered transition metal dichalcogenides, such as tungsten disulfide, are exfoliated into atomically thin flakes. If they could be easily exfoliated, layered materials would become a diverse source… Expand

High-concentration solvent exfoliation of graphene.
A method is demonstrated to prepare graphene dispersions at high concentrations, up to 1.2 mg mL(-1), with yields of up to 4 wt% monolayers. This process relies on low-power sonication for long… Expand

Scalable production of large quantities of defect-free few-layer graphene by shear exfoliation in liquids.
To progress from the laboratory to commercial applications, it will be necessary to develop industrially scalable methods to produce large quantities of defect-free graphene. Here we show that… Expand

Ultrafast saturable absorption of two-dimensional MoS2 nanosheets.
Employing high-yield production of layered materials by liquid-phase exfoliation, molybdenum disulfide (MoS2) dispersions with large populations of single and few layers were prepared. Electron… Expand

High-concentration, surfactant-stabilized graphene dispersions.
A method is presented to produce graphene dispersions, stabilized in water by the surfactant sodium cholate, at concentrations up to 0.3 mg/mL. The process uses low power sonication for long times… Expand

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 solubility… Expand

Broadband Nonlinear Optical Response of Graphene Dispersions
All dispersions werestable against sedimentation and with only minimal aggregationoccurring over a period of weeks. Experimental and theoreticalanalyses reveal that the surface energies of the… Expand

Solvent exfoliation of transition metal dichalcogenides: dispersibility of exfoliated nanosheets varies only weakly between compounds.
We have studied the dispersion and exfoliation of four inorganic layered compounds, WS(2), MoS(2), MoSe(2), and MoTe(2), in a range of organic solvents. The aim was to explore the relationship… Expand
