researchers — who struggled for several years to build electronic circuits out of graphene with very limited results (except for radio-frequency applications) — have now succeeded in making a variety of electronic components from an amazing new material: a 2D version of molybdenum disulfide (MoS2). the material could help usher in radically new products, from whole walls that glow to clothing with embedded electronics to glasses with built-in display screens. “It’s the most exciting time for electronics in the last 20 or 30 years. It’s opening up the door to a completely new domain of electronic materials and devices.”

in general, materials science remains under-appreciated as the source of much of our wealth and comfort, both current and future.
