A step closer to single-atom data storage

13-Jul-2018

Despite the rise of solid-state drives, magnetic storage devices such as conventional hard drives and magnetic tapes are still very common. But as our data-storage needs are increasing at a rate of almost 15 million gigabytes per day, scientists are turning to alternative storage devices. One of ...

Researchers couple artificial atom to acoustic resonator

13-Jul-2018

Researchers from Russia and Britain have demonstrated an artificial quantum system, in which a quantum bit interacts with an acoustic resonator in the quantum regime. This allows the familiar effects of quantum optics to be studied on acoustic waves and enables an alternative approach to quantum ...

Why gold-palladium alloys are better than palladium for hydrogen storage

11-Jul-2018

Materials that absorb hydrogen are used for hydrogen storage and purification, thus serving as clean energy carriers. The best-known hydrogen absorber, palladium (Pd), can be improved by alloying with gold (Au). New research led by The University of Tokyo Institute of Industrial Science explains ...

Electrochemically-produced ammonia could revolutionize food production

11-Jul-2018

Steven McIntosh wants to transform the way ammonia is produced. He hopes to create a viable alternative to the conventional method, which uses massive amounts of energy and emits harmful carbon dioxide. He's exploring a sustainable electrochemical method to efficiently drive the chemical reaction ...
