With a STEM microscope, ORNL’s Ondrej Dyck brought two, three and four silicon atoms together to build clusters and make them rotate within a layer of graphene, a two-dimensional layer of carbon atoms that exhibits unprecedented strength and high electrical conductivity.

Scientists have used genetically engineered bacteria to recreate a masterpiece at a microscopic scale. By engineering E. coli bacteria to respond to light, they’ve guided the bacteria like tiny drones toward patterns that depict Leonardo da Vinci’s Mona Lisa. It’s not artistic recognition they’re after. Rather, the researchers want to show that these engineered organisms […]
A team of researchers at Germany’s Karlsruhe Institute of Technology have developed a quantum transistor using just a single atom, and capable of operating at room temperature. The device points toward major new frontiers in computing power and efficiency. Transistors, which control the flow of electronic signals, are the basis of modern electronics. The steady […]
Made of two stacked layers of graphene, diamene temporarily becomes harder than bulk diamonds under impact.
By all measures, graphene shouldn’t exist. The fact it does comes down to a neat loophole in physics that sees an impossible 2D sheet of atoms act like a solid 3D material.
