Built from the bottom up, nanoribbons pave the way to ‘on–off’ states for graphene

Image
GNR-2.jpg OAK RIDGE, Tenn., March 30, 2017—A new way to grow narrow ribbons of graphene, a lightweight and strong structure of single-atom-thick carbon atoms linked into hexagons, may address a shortcoming that has prevented the material from achieving its full potential in electronic applications. Graphene nanoribbons, mere billionths of a meter wide, exhibit different electronic properties than two-dimensional sheets of the material.

Two-dimensional MXene materials get their close-up

March 14, 2017—Researchers have long sought electrically conductive materials for economical energy-storage devices.  Two-dimensional (2D) ceramics called MXenes are contenders. Unlike most 2D ceramics, MXenes have inherently good conductivity because they are molecular sheets made from the carbides and nitrides of transition metals like titanium.
