GRAPHENE REPORT

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


U Cal Berkeley researchers developing graphene-based earphone-sized speaker. Outperforms best current earphones using almost no specialized acoustic design.

National U of Singapore researchers created water corrosive enough to etch diamond. By accident. They attached layer of graphene on diamond, heated to high temp to encourage bonding. Water molecules trapped between diamond and graphene transformed into supercritical phase, corroded the diamond.

Biofutures (UK) to focus on low-cost graphene production. Name change to Graphene Nanochem. Market cap L162M on UK AIM exchange, trading suspended in Dec. Holds exclusive license to Catalyx process. Catalyst extracts graphene from biogases (methane).

Euro Regional Development Fund awarded L23M to L38M National Graphene Inst at U of Manchester (UK). Manchester interest in 2 graphene comps: 2-D Tech and Graph Industries.

Japan Advanced Inst of Science & Tech, U of Southampton (UK) developing new way to make ultra-fine graphene nanodevices using helium-ion microscopy. Selectively sputters graphene to create intricate nanoscale designs. Developed 2 devices. Ultrathin suspended graphene nanoribbons for extremely sensitive gas molecular sensors. And densely integrated graphene quantum dots for quantum info processing techs.

Almost 70 yrs ago, Atomic Collapse - a quantum mech phenom - was predicted. Using graphene, Berkeley Lab, U of Cal researchers imaged the states, showed they occur around super-large atomic nuclei. Graphene made it possible to review because of extraordinary relativistic nature of electrons in graphene. Yields much smaller nuke charge threshold for creating special supercritical nuclei that will exhibit Atomic Collapse behavior. Highly relevant for future devices.

UC Riverside researchers found out what causes low-freq electronic 1/f noise ("pink noise" or "flicker noise"). Used graphene sheets to find surface phenom that shows up in situations thinner than 2.5nm.
