GRAPHENE REPORT

MIT scientists have shown nanoporous graphene can filter salt from water at 2-3 orders of magnitude faster than today's best desal tech (reverse osmosis).

NIST, U of MD researchers have shown subjecting graphene to mech strain (suspending it over shallow holes in substrate of Si02) can mimic effects of mag fields and create quantum dot.

U Cal researchers use IR beam to send ripples of electrons along graphene surf. The plasmon oscillations controlled with simple el current.

National U of Singapore investing $11.8M in graphene prod facility for new tech dev. Operational by Oct.

Stony Brook dev'd graphene-based MRI contrast agent potentially safer, cheaper than current gadolinium. Can also improve disease detection. Lead researcher started Theragnostic Techs to commercialize.

New graphene-based film can detect trace amounts of contaminants in water. Graphene sheet deposited with silver nanoparticles, TiO2 on either side.

U of MD research discovered bilayer graphene can make ultra-fast, broad-range photodetectors.

CZ, FR, Can and US researchers ID'd all main criteria to make artificial graphene. High-quality 2D semiconductors to fab new crystal w/ "artificially"-created honeycomb lattice.

Mich State, Shenyong Inst dev'd new method to accurately cut graphene. Atomic force microscope-based nanorobot. In combo w/ current multi-tip tech can cheaply produce graphene-based, large-scale, high effic nanodevices.

U of FL dev'd most effic graph-based solar cell to date. Increased from 1.9% to 8.6%. Single layer of graph on top of si wafer serves as Shottky junction.

U of Buffalo dev'd graph-based anti-corrision coating. Enviro friendly vs. hexavalent chromium (potential carcinogen) coatings now used.

Samsung Inst dev'd new graph-si Shottky barrier that enables graph to swith el current on/off.

Inst of Photonic Sciences (Barcelona) dev'd photodetector using graph and Q dots. 1B x more sensitive to light because of dots.
