Resistance switching at the nanometre scale in amorphous carbon
IBM Research, Plarion, Swiss Light Source

"Recently, carbon nanotubes and graphene have been proposed for non-volatile memory applications. Amorphous carbon also shows promise as another potential candidate. The surprising result is that there is remarkable similarity between amorphous carbon and traditional phase changing materials such as germanium and antimony telluride."

Simultaneous positioning and orientation of a single nano-object by flow control: theory and simulations
NIST, University of Maryland

"The [nano object] doesn't have to have any special properties. All we do is rely on viscous drag. The technique could be used to both rotate and translate carbon or metallic nanowires to build optical circuits for example. Another application is in biology where you could use this technique to control a sensor and point it at a cell that is floating around in its natural fluidic environment."

On the structure and topography of free-standing chemically modified graphene
University of Warwick

"From our investigations, both AFM and electron diffraction clearly indicate that the topography of graphene oxide is different to that previously reported for graphene. The local strain induced by the functionalization causes short range corrugations and this will have important implications both for the mechanical properties and for the chemical reactivity."

Dangling-bond charge qubit on a silicon surface
National Research Council of Canada, University of Alberta, University of Calgary, Southeast University

"What's remarkable about our charged qubit, is its extremely small size. Because in our case, the double well features are achieved on the atomic scale. Such a qubit with low de-coherence enables many quantum computation operations to be performed before the onset of critical decoherence renders it unreliable."

Zone-plate focusing of Bose–Einstein condensates for atom optics and erasable high-speed lithography of quantum electronic components
University of Nottingham, Eberhard-Karls-Universität Tübingen, University of Melbourne

"Our paper predicts that Bose–Einstein condensates can be sharply focused by diffracting them from Fresnel zone plates. Additionally, if the atom clouds are deposited on semiconductor devices containing a 2D electron gas, they may imprint quantum wires or components on the nanometre scale. The difference and novelty in ultracold atom techniques is that the lithography becomes potentially re-writable, because we can remove the atoms using ultraviolet radiation."
