Hydrogen responds to pressure and temperature extremes differently. Under ambient conditions hydrogen is a gaseous two-atom molecule. As confinement pressure increases, the molecules adopt different states of matter — like when water ice melts to liquid. Scientists have now combined hydrogen with its heavier sibling deuterium and created a novel, disordered, ‘Phase IV’-material. The molecules interact differently than have been observed before, which could be valuable for controlling superconducting and thermoelectric properties of new materials.
