FLASH 2 (IMAGE) Rice University Caption An electron microscope image shows tungsten disulfide in its metastable 1T state. The orange dots represent sulfur atoms, the blue represent tungsten. Rice University scientists used flash Joule heating to tailor the properties of 2D dichalcogenides, quickly turning them into metastable metallics for electronic and optical applications.
