 Nature NanotechnologyGraphene joins the race to redefine the ampere A new joint innovation by the National Physical Laboratory and the University of Cambridge could pave the way for redefining the ampere in terms of fundamental constants of physics. The world's first graphene single-electron pump, described in a paper today in Nature Nanotechnology, provides the speed of electron flow needed to create a new standard for electrical current based on electron charge.

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.

Physical Review LettersResearcher construct invisibility cloak for thermal flow By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of heat. A structured plate of copper and silicon conducts heat around a central area without the edge being affected. The results are presented in the Physical Review Letters journal.

Physical Review LettersMagnetic vortex antennas for wireless data transmission Three-dimensional magnetic vortices were discovered by scientists from the Helmholtz-Zentrum Dresden-Rossendorf together with colleagues from the Paul Scherrer Institute within the scope of an international cooperation. The results were published in the scientific journal Physical Review Letters (DOI: 10.1103/PhysRevLett.110.177201). Vortex states are potential antennas for the ultrafast, wireless data transmission of tomorrow. Contact: Anja Weigl

Physical Review LettersColumbia engineers manipulate a buckyball by inserting a single water molecule Columbia Engineering researchers have developed a technique to isolate a single water molecule inside a buckyball and drive motion of the "big" nonpolar ball through the encapsulated "small" polar H2O molecule, a controlling transport mechanism in a nanochannel under an external electric field. This method could lead to new applications including effective ways to control drug delivery and to assemble C60-based functional 3D structures at the nanoscale level.
