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

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 timesExpand

Size effects and the problem with percolation in nanostructured transparent conductors.
Much research is underway at present to develop nanostructured transparent conductors for use as electrodes. Transparent electrodes typically require high visible transmittances, T > 90%, and so mustExpand

Performance of III–V Solar Cells as Indoor Light Energy Harvesters
Energy-harvesting systems provide power autonomy to individual wireless sensor nodes, allowing simpler deployment, as compared with wired nodes and longer lifetimes than battery-powered ones. IndoorExpand

Transparent, flexible, and highly conductive thin films based on polymer-nanotube composites.
We have prepared flexible, transparent, and very conducting thin composite films from poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate), filled with both arc discharge and HIPCO single-walledExpand

Edge and confinement effects allow in situ measurement of size and thickness of liquid-exfoliated nanosheets.
Two-dimensional nanomaterials such as MoS2 are of great interest both because of their novel physical properties and their applications potential. Liquid exfoliation, an important production method,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

Production of Molybdenum Trioxide Nanosheets by Liquid Exfoliation and Their Application in High-Performance Supercapacitors
Here, we demonstrate a simple method to exfoliate layered molybdenum trioxide (MoO3) crystallites to give multilayer MoO3 nanosheets dispersed in solvents. Exfoliation is achieved by sonicating MoO3Expand
