  • paper that's stronger than steel
  • University of Technology, Sydney scientists have reported remarkable results in developing a composite material based on graphite that is a thin as paper and ten times stronger than steel.
  • Graphene paper (GP) is a material that can be processed, reshaped and reformed from its original raw material state - graphite.

  • These graphene nanosheet stacks consist of monolayer hexagonal carbon lattices and are placed in perfectly arranged laminar structures which give them exceptional thermal, electrical and mechanical properties.

  • Researchers create super-small transistor, artificial atom powered by single electrons
  • The SketchSET—which is the first single-electron transistor made entirely of oxide-based materials—consists of an island formation that can house up to two electrons. The number of electrons on the island—which can be only zero, one, or two—results in distinct conductive properties. Wires extending from the transistor carry additional electrons across the island.
  • One virtue of a single-electron transistor is its extreme sensitivity to an electric charge, Levy explained. Another property of these oxide materials is ferroelectricity, which allows the transistor to act as a solid-state memory. The ferroelectric state can, in the absence of external power, control the number of electrons on the island, which in turn can be used to represent the 1 or 0 state of a memory element. A computer memory based on this property would be able to retain information even when the processor itself is powered down, Levy said. The ferroelectric state also is expected to be sensitive to small pressure changes at nanometer scales, making this device potentially useful as a nanoscale charge and force sensor.

  • FastSCAN is lightweight and ultra-portable. The entire system is supplied in a briefcase, and setup only takes a few minutes. As a result, you can readily scan objects onsite, in their natural environments. The first laser scanner you can easily travel with, FastSCAN sets up almost anywhere, indoor or out.
