Growing graphene without the mess
A conceptual illustration of an array of single atom-thick graphene transistors. Graphene is often hailed as potentially supplanting silicon in electronics, with its remarkable strength, despite its one atom-thick sheets, and its off-the-charts electrical properties. Researchers are experimenting with growing full-scale, four-inch graphene wafers. (Credit: Shivank Garg)

Solar cells nano-inked onto rooftops
A team of engineers is using nanoparticle “inks” (as shown here) to develop cheap solar cells. Lead researcher Brian Korgel says the inks, which are semitransparent, could help realize the prospect of having windows that double as solar cells.
