Laser Scribing of High-Performance and Flexible Graphene-Based Electrochemical Capacitors
It is shown that graphite oxide sheets can be converted by infrared laser irradiation into porous graphene sheets that are flexible, robust, and highly conductive, and hold promise for high-power, flexible electronics. Expand
Scalable fabrication of high-power graphene micro-supercapacitors for flexible and on-chip energy storage.
This work demonstrates a scalable fabrication of graphene micro-supercapacitors over large areas by direct laser writing on graphite oxide films using a standard LightScribe DVD burner, which demonstrates a power density among the highest values achieved for any supercapacitor. Expand
Synthesis of Ultra-Incompressible Superhard Rhenium Diboride at Ambient Pressure
Rhenium diboride (ReB2), synthesized in bulk quantities via arc-melting under ambient pressure, rivals materials produced with high-pressure methods in properties and may find applications in cutting when the formation of carbides prevents the use of traditional materials such as diamond. Expand

Electric conductivity measurements indicate a 10000-fold increase in conductivity after chemical reduction to graphene, and temperature-dependent conductivity indicates that the graphene-like sheets exhibit semiconducting behavior. Expand
High-throughput solution processing of large-scale graphene.
The chemically converted graphene sheets that were produced have the largest area reported to date (up to 20 x 40 microm), making them far easier to process, and field-effect devices have been fabricated by conventional photolithography, displaying currents that are three orders of magnitude higher than previously reported for chemically produced graphene.

Polyaniline nanofibers with uniform diameters between 30 and 50 nm can be made in bulk quantities through a facile aqueous/organic interfacial polymerization method at ambient conditions and have superior performance in both sensitivity and time response to vapors of acid and base. Expand
A general chemical route to polyaniline nanofibers.
Interfacial polymerization is shown to be readily scalable to produce bulk quantities of nanofibers and the measured Brunauer-Emmett-Teller surface area of the nan ofibers increases as the average diameter decreases. Expand
A Chemical Route to Carbon Nanoscrolls
This work extends the recent work on making colloidal suspensions of layered compounds to graphite to explore the concept that scrolling could lead to nanotube-like structures through a scrolling mechanism. Expand
