Absorbing electromagnetic energy while avoiding the heat

Electrical engineers at Duke University have created the world's first electromagnetic metamaterial made without any metal. The device's ability to absorb electromagnetic energy without heating up has direct applications ...

Lab tests made cheaper with chips

(Phys.org) —University of New South Wales PhD candidate Ryan Pawell hopes a manufacturing technique he created will cut the cost of medical diagnostics to a few dollars per experiment or test.

In situ chemical imaging at the sub-biofilm-scale now possible

(Phys.org) —Catching biofilm chemistry with images has always been a cold or dry affair. Now, a multidisciplinary team at Pacific Northwest National Laboratory is the first to demonstrate imaging of a biofilm's chemical ...

Laser guided codes advance single pixel terahertz imaging

The universe is awash in terahertz (THz) waves, as harmless as they are abundant. But unlike other regions of the electromagnetic spectrum, THz has proven to be extremely difficult to manipulate in order to capture novel ...

Carbon nanotubes for molecular magnetic resonances

Researchers at ICFO have developed a new technique for measuring very weak forces on a molecular scale. Thanks to the use of carbon nanotubes, they have achieved the highest level of sensitivity to date. These results published ...
