University of Texas at Austin When it comes to the growth of graphene — an ultrathin, ultrastrong, all-carbon material — it is survival of the fittest, according to researchers at The University of Texas at Austin. The team used surface oxygen to grow centimeter-size single graphene crystals on copper. The crystals were about 10,000 times as large as the largest crystals from only four years ago. Very large single crystals have exceptional electrical properties. "The game we play...

"Smart" alloy stretches, contracts by almost 10 percent By chance, two friends, out of the 3,000 scientists attending the fall 2006 Materials Research Society meeting in Boston, ran into each other outside the Hynes Convention Center. Peter Mllner and David Dunand had both graduated from the Swiss Federal Institute of Technology (ETH) Zurich. Mllner, now at Boise State University, was researching magnetic alloys that can change their shape in the presence of a magnetic field. Meanwhile,...
