Interlayer distance in graphite oxide gradually changes when water is added

June 30, 2014 12:22 pm | by EurekAlert! | Comments

Physicists from Umeå University and Humboldt University in Berlin have solved a mystery that has puzzled scientists for half a century. They show with the help of powerful microscopes that the distance between graphite oxide layers gradually increases when water molecules are added....

Researchers unzip nanotubes by shooting them at 15,000 mph

June 30, 2014 12:20 pm | by EurekAlert! | Comments

Carbon nanotubes "unzipped" into graphene nanoribbons by a chemical process invented at Rice University are finding use in all kinds of projects, but Rice scientists have now found a chemical-free way to unzip them. The Rice lab of materials scientist Pulickel Ajayan discovered that nanotubes that hit a target ...

Improved method for isotope enrichment could secure a vital global commodity

June 30, 2014 9:20 am | by EurekAlert! | Comments

Researchers at The University of Texas at Austin have devised a new method for enriching a group of the world's most expensive chemical commodities, stable isotopes, which are vital to medical imaging and nuclear power, as reported this week in the journal Nature Physics. For many isotopes, the new method is cheaper than existing methods....

Watching individual neurons respond to magnetic therapy

June 30, 2014 9:16 am | by EurekAlert! | Comments

Engineers and neuroscientists at Duke University have developed a method to measure the response of an individual neuron to transcranial magnetic stimulation (TMS) of the brain. The advance will help researchers understand the underlying physiological effects of TMS -- a procedure used to treat psychiatric disorders....

Noninvasive brain control

June 30, 2014 9:12 am | by EurekAlert! | Comments

Optogenetics, a technology that allows scientists to control brain activity by shining light on neurons, relies on light-sensitive proteins that can suppress or stimulate electrical signals within cells. This technique requires a light source to be implanted in the brain, where it can reach the cells to be controlled....

Single-pixel 'multiplex' captures elusive terahertz images

June 30, 2014 9:10 am | by EurekAlert! | Comments

A novel metamaterial enables a fast, efficient and high-fidelity terahertz radiation imaging system capable of manipulating the stubborn electromagnetic waves, advancing a technology with potential applications in medical and security imaging, a team led by Boston College researchers reports in the online edition of the journal Nature Photonics....

Bending the rules

June 30, 2014 9:02 am | by EurekAlert! | Comments

For his doctoral dissertation in the Goldman Superconductivity Research Group at the University of Minnesota, Yu Chen, now a postdoctoral researcher at UC Santa Barbara, developed a novel way to fabricate superconducting nanocircuitry. However, the extremely small zinc nanowires he designed did some unexpected — and sort of funky — things....
