The nano research team led by professors Helge Weman and Bjørn-Ove Fimland at the Norwegian University of Science and Technology’s (NTNU) Department of Electronic Systems has succeeded in creating light-emitting diodes, or LEDs, from a nanomaterial that emits ultraviolet light. It is the first time anyone has created ultraviolet light on a graphene surface. “We’ve…

Chemical reactions take place around us all the time – in the air we breathe, the water we drink, and in the factories that make products we use in everyday life. And those reactions happen way faster than you can imagine. Given optimal conditions, molecules can react with each other in a quadrillionth of a…
