Abstract | Full Text | PDF Direct visualization of large-area graphene domains and boundaries by optical birefringency pp29 - 34 Dae Woo Kim, Yun Ho Kim, Hyeon Su Jeong and Hee-Tae Jung doi:10.1038/nnano.2011.198 The domain structure of macroscopic graphene samples can be simply observed by covering them with liquid-crystal molecules. Abstract | Full Text | PDF Mechanically controlled molecular orbital alignment in single molecule junctions pp35 - 40 Christopher Bruot, Joshua Hihath and Nongjian Tao doi:10.1038/nnano.2011.212 The conductance of a single molecule of 1,4'-benzenedithiol bridged between two gold electrodes increases as it is stretched because the energy of the highest occupied molecular orbital is shifted towards the Fermi energy of the electrodes, leading to a resonant enhancement of the conductance. Abstract | Full Text | PDF A surface-anchored molecular four-level conductance switch based on single proton transfer pp41 - 46 Willi Auwärter, Knud Seufert, Felix Bischoff, David Ecija, Saranyan Vijayaraghavan, Sushobhan Joshi, Florian Klappenberger, Niveditha Samudrala and Johannes V. Barth doi:10.1038/nnano.2011.211 A porphyrin molecule anchored to a silver surface can function as a four-level conductance switch in which a single hydrogen atom in the inner cavity of the molecule is manipulated by electrons from the tip of a scanning tunnelling microscope.
