GRAPHENE REPORT

Graphene is a 1-atom thick sheet of carbon atoms in a hexagonic crystal lattice. 200x stronger than steel. Tougher than diamond. World's thinnest material. Flexible, transparent. Conducts el and heat very well. Stocks: AIXG, CVV, FCSMF, NGPHF, GTI, CHGI, PKX.


New York awarded $250K each to 2 graphene-based energy storage projects. Graphene Devices to develop graphene-based capacitors with 3x energy density of current devices at same cost. Custom Electronics wants to develop electrolytic graphene capacitor for grid backup.

Rice U, NIST announced $2.7M, 5-year project to study how nanoparticles - particularly fullerenes, nanotubes and graphene - operate and interact at molecular, atomic scales.

DOE selected XG Sciences to develop high-energy lithium ion batt materials for extended-range EV's. Silicon-graphene nanocomposite anode material. Significant increases in energy storage capacity over traditional graphite. Collab with LG Chem Power, GA Tech.

U of Manchester scientists made nanoscale transformer from stacked graphene sheets separated by record 4 atomic layers of boron nitride for insulators.

Scientists from U of Alberta, National Resource Council of Canada developed new material - a 3D sponge-like graphene that can make super capacitor electrodes for supercapacitors to compete with lith-ion batts. Multiwalled carbon nanotubes using cobalt and a cyanine.

Beijing Inst of Tech created lightest graphene framework to date. Fire resistant - able to withstand repeated burning without structural damage. Record-breaking adsorption, capacitance. Doped graphene with nitrogen. Able to absorb 200-600x its own weight of oil, other non-polar liquids.

Angstron Materials developed new graphene-modified lubricant. US patent. Improved thermal conductivity, friction reduction, exceptional viscosity stability.

Nobel professor, colleague released graphene roadmap. Possible aps, different ways to make it. 1st ap is conductors for touch screen displays. By '20, photodetectors, wireless com, THz generators. Replacing silicon and delivering anti-cancer drugs further out.

Graphene can be selectively and reversibly doped with light. Plasmonic nano antenna attached to graphene. Graphene doped by hot electrons generated from antenna. Doping control by changing antenna size or laser wavelength, power density.

Lawrence Livermore new method to mass produce graphene-based materials. Polymer-derived carbon foams, selectively removing carbon atoms from unstructured carbon, graphite nanoplatelets. Physical properties can be changed by external signal. Inexpensive, scalable. May be good for energy storage or capacitive desalination.

Singapore A STAR Inst, US researchers have new way to pack molecules using graphene and graphone (graphene hydrogenated on 1 side). Idea is to trap molecules. Stable well above room temp. Useful energy storage or bio aps.

Graphene market to reach $100M by '18. Aps include RFID, smart packaging, supercapacitors, composites, sensors, computer logic and memory.

UT Dallas researchers shrunk size of graphene pore to < 1NM. Small enough to thread a DNA strand. Possible use in DNA sequencing. Uses electron beam from advanced electron microscope and 1,200C  heat. 1st time graphene nanopore controlled.

U of CO Boulder researchers demo'd graphene membranes with tiny pores can effectively, efficiently separate gas molecules using UV light. Uses in NG production, power plant CO2 emissions reduction.

US Navy researchers discovered way to use graphene as extremely thin "tunnel barrier" to conduction. Useful for spintronic devices.

Highly transparent, flexible, resistive memory made from silicon oxide, graphene. Rice U researchers who in '08 found SiOx alone can be a switch.

Planar Tech offering graphene samples - graphene on copper foil, graphene on UV tape, large-area single-crystal graphene, more.

Iran researchers have process to produce graphene with laser ablation in liquid nitrogen with fast-flow circulation.

Denmark researchers say graphene can be used to develop hyper lens to work in THz range. Lens behaves as metal in 1 direction, insulator in other. Tunable by applying voltage to graphene layers.

Graphene coating can make copper up to 100x more resistant to corrosion. Monash U, Rice U.

BASF, Max Planck, Carbon Materials Innovation Center researching science, aps of graphene. 10M Euro invested so far for 3 years.
