Making an invisible electric wire: Guiding electricity with sound

Electric sparks are used for welding, powering electronics, killing germs or for igniting the fuel in some car engines. Despite their usefulness, they are hard to control in open space—they split into chaotic branches that ...

Plasma technique doubles etch rate for 3D NAND flash memory

To store ever more data in electronic devices of the same size, the manufacturing processes for these devices need to be studied in greater detail. By investigating new approaches to making digital memory at the atomic scale, ...

SMART: One step closer to nuclear fusion with its first plasma

In a pioneering approach to achieve fusion energy, the SMART device has successfully generated its first tokamak plasma. This step brings the international fusion community closer to achieving sustainable, clean, and virtually ...

Experiment validates electric ion thruster simulations

Predicting the lifetime of an electric ion thruster is notoriously difficult. You have to account for the chamber wall effects, which are not present in space environments. Researchers within several different aerospace disciplines ...
