UMD MRSEC Takes Its Giant Buckyball on the Road
D. Hammer, A. PrasertchoungUniversity of Maryland MRSEC DMR0520471
UMD MRSEC has developed an exciting nanoscience demonstration known as the Giant Buckyball. The Giant C60, along with the smaller C20, has been used in a variety of venues including museums such as the Smithsonian Spark!Lab in Washington, DC and Port Discovery Children’s Museum in Baltimore, MD; summer camps; and science festivals to engage students and their families in the exploration of research science and engineering.

To fully understand the behavior of graphene's electrons, Georgia Tech and NIST scientists employ the extremes of ultra-low temperature and large magnetic field. In a new ultra-low temperature scanning tunneling microscope (ULT-STM) constructed at NIST, graphene remains pristine for weeks, enabling precise observations of electron energy levels and interactions. Using multilayer epitaxial graphene prepared at Georgia Tech, the collaborato

Metal Atom-Directed Traffic: Building Efficient 3-D Materials
Rajesh Sathiyanarayanan and T. L. Einstein University of Maryland MRSEC, DMR 0520471
The race to build smaller and more efficient computer chips and batteries faces major challenges in materials organization. Current smart phones, for example, are based upon layered (“2-D”) materials, but nanoscale designs that utilize 3-D architecture are envisioned. To access this third dimension in materials organization, scientists must find ways to direct the flow of atoms before locking in structure.
