Tuning quantum materials with hydrogen gas

Researchers at TU Delft have discovered a method to stretch and compress quantum materials using hydrogen gas. They demonstrated this effect using a tiny string of a material called tungsten trioxide, which acts as a sponge for hydrogen. The research is a promising new step in the development of micromechanical resonators, which have a wide range of possible applications. They can be used in inkjet printers, as sensors for environmental conditions, and as active components in future nano-electronics.
