Angewandte Chemie International EditionFriction in the nano-world Whether in vehicle transmissions, hip replacements, or tiny sensors for triggering airbags: The respective components must slide against each other with minimum friction to prevent loss of energy and material wear. Investigating the friction behavior of nanosystems, scientists from the Technische Universitaet Muenchen have discovered a previously unknown type of friction that sheds new light on some previously unexplainable phenomena.

NatureFirst direct proof of Hofstadter butterfly fractal observed in moiré superlattices A team of researchers from Columbia University, City University of New York, the University of Central Florida, and Tohoku University and the National Institute for Materials Science in Japan, have directly observed a rare quantum effect that produces a repeating butterfly-shaped energy spectrum, confirming the longstanding prediction of this quantum fractal energy structure called Hofstadter's butterfly. The study, which focused on moiré-patterned graphene, is published in Nature. Contact: Holly Evarts

Public Release: 14-May-2013
Nature PhotonicsUC Riverside scientists discovering new uses for tiny carbon nanotubes Nanotubes are stronger than steel and smaller than any element of silicon-based electronics. They can potentially process information faster while using less energy. The challenge has been figuring out how to incorporate these properties into useful electronic devices. Now scientists at the University of California, Riverside have discovered that by adding ionic liquid -- a kind of liquid salt -- they can modify the optical transparency of single-walled carbon nanotube films in a controlled pattern.

Jounral of the American Chemical SocietyPitt chemists demonstrate nanoscale alloys so bright they could have potential medical applications Alloys like bronze and steel have been transformational for centuries, yielding top-of-the-line machines necessary for industry. As scientists move toward nanotechnology, however, the focus has shifted toward creating alloys at the nanometer scale -- producing materials with properties unlike their predecessors. Now, research at the University of Pittsburgh demonstrates that nanometer-scale alloys possess the ability to emit light so bright they could have potential applications in medicine. Contact: B.

Nature CommunicationsMaking gold green: New non-toxic method for mining gold Northwestern University scientists have struck gold in the laboratory. They have discovered an inexpensive and environmentally benign method that uses simple cornstarch -- instead of cyanide -- to isolate gold from raw materials in a selective manner. This green method extracts gold from crude sources and leaves behind other metals that are often found mixed together with the crude gold.

Nature PhysicsNew magnetic graphene may revolutionize electronics Researchers from IMDEA-Nanociencia Institute and from Autonoma and Complutense Universities of Madrid have managed to give graphene magnetic properties. The breakthrough, published in the journal Nature Physics, opens the door to the development of graphene-based spintronic devices, that is, devices based on the spin or rotation of the electron, and could transform the electronics industry.

Nature CommunicationsFlawed diamonds promise sensory perfection By extending the coherence time of electron states to over half a second, a team of scientists from Lawrence Berkeley National Laboratory, the University of California at Berkeley, and Harvard University has improved the performance of one of the most potent sensors of magnetic fields on the nanoscale -- a diamond defect no bigger than a pair of atoms called a nitrogen vacancy center. The achievement is important news for nanoscale sensors and quantum computing.
