Save time using maths: Analytical tool designs corkscrew-shaped nano-antennae

For the first time, scientists have derived analytically how corkscrew-shaped nano-antennas interact with light. The mathematical tool can be used to calculate the geometry that a nano-antenna must have for specific applications in sensor technology or information technology.

Study identifies main culprit behind lithium metal battery failure

A research has discovered the root cause of why lithium metal batteries fail – bits of lithium metal deposits break off from the surface of the anode during discharging and are trapped as ‘dead’ or inactive lithium that the battery can no longer access.

Atomically thin straintronic devices

By studying flexible and transparent photodetectors based on single-layer MoS2 under the application of biaxial strain, researchers have developed atomically thin photodetectors whose characteristics can be controlled by means of an externally applied strain. This strain can be reversibly applied through the thermal expansion (shrinkage) of the substrate material, which induces tensile (compressive) biaxial stress. These results emphasize the possibilities of a new kind of electronics – straintronics – in which mechanical deformations are used to modify not only the geometry of the device, but its properties and performance as well.

Scientists develop a metamaterial for applications in magnonics, an alternative to conventional electronics

Physicists have demonstrated the real possibility of using superconductor/ferromagnet systems to create magnonic crystals, which will be at the core of spin-wave devices to come in the post-silicon era of electronics.
