A convenient way to selectively prepare germanium sulfide nanostructures

Researchers have found a convenient way to selectively prepare germanium sulfide nanostructures, including nanosheets and nanowires, that are more active than their bulk counterparts and could open the way to lower cost and safer optoelectronics, solar energy conversion and faster computer circuitry.

Electrical transmission at the atomic level

Scientists have developed a new approach to how signals might be transmitted at the atomic level. This could be especially important for realising logic structures with strictly defined functions on the basis of individual atoms, which in turn could find application in transistors or diodes.

The first phononic crystal that can be altered in real time

Using an acoustic metadevice that can influence the acoustic space and can control any of the ways in which waves travel, engineers have demonstrated, for the first time, that it is possible to dynamically alter the geometry of a three-dimensional colloidal crystal in real time.
