Hunter and Nanometrics Monitor Seismic Zones and Oilfield Induced Seismicity
Ottawa, Canada (SPX) May 06, 2014 -
Hunter Communications has teamed with Nanometrics, one of the world's leading manufacturers of seismology systems and instrumentation, to develop an induced seismic and microseismic monitoring application via satellite for oil and gas drilling sites where hydraulic fracturing ("fracking") is employed.
The application is deployed by the Nanometrics LIBRA very small aperture terminal (VSAT) ...

Harnessing Magnetic Vortices for Making Nanoscale Antennas
Upton NY (SPX) May 06, 2014 -
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory are seeking ways to synchronize the magnetic spins in nanoscale devices to build tiny yet more powerful signal-generating or receiving antennas and other electronics. Their latest work, published in Nature Communications, shows that stacked nanoscale magnetic vortices separated by an extremely thin layer of copper can b ...

New revolutionary sensor links pressure to color change
Riverside CA (SPX) May 06, 2014 -
Imagine an automobile crash test that uses test dummies painted all over with a substance that can change color according to the levels of stress that various parts of the dummies' bodies will endure. Such a "color map" could provide vital information to engineers designing safer automobiles.
Or imagine baseball gloves that when worn show the batters if they are using the appropriate amoun ...

Molecular Foundry Opens the Door to Better Doping of Semiconductor Nanocrystals
Berkeley CA (SPX) May 06, 2014 -
The icing on the cake for semiconductor nanocrystals that provide a non-damped optoelectronic effect may exist as a layer of tin that segregates near the surface.
One method of altering the electrical properties of a semiconductor is by introducing impurities called dopants. A team led by Delia Milliron, a chemist at Berkeley Lab's Molecular Foundry, a U.S Department of Energy (DOE) nation ...

High Quality Three-Dimensional Nanoporous Graphene
Sendai, Japan (SPX) May 06, 2014 -
Three-dimentional (3D) nanoporous graphene with preserved 2D Dirac electronic characters was successfully synthesized by Dr. Yoshikazu Ito and Prof. Mingwei CHEN at Advanced Institute for Materials Research (AIMR), Tohoku University.
The nanoporous graphene is constructed by a single layer graphene sheet that is continuously inter-connected to form a complex 3D network structure. This free ...

UN nuclear inspectors arrive in Iran
Tehran (AFP) May 05, 2014 -
A delegation from the International Atomic Energy Agency has arrived in Iran to visit two nuclear sites ahead of the next round of political talks with world powers next week.
After meeting officials from the Atomic Energy Organisation of Iran on Monday the IAEA team will travel to Saghand uranium mine and the Ardakan yellow-cake production site, the official IRNA news agency said.
The f ...
