      Nanosphere lithography with nanosphere-protein conjugates is proposed by R. E. Gyurcsányi and co-workers as a generic method to create surface molecularly imprinted polymer films for selective protein recognition. On page 4703, electrosynthesis of a polymer film in the voids of the nanosphere array followed by removal of the nanospheres generates complementary cavities bearing the imprints of the proteins.

      A graphite ‘flower’ is produced by V. Palermo and co-workers in order to study the production and exfoliation mechanism of soluble of graphene and graphene oxide nanosheets due to chemical etching, electrochemical treatment, or sonication in organic solvents of bulk graphite. In the background of the back cover image, the same material is visualized by electron microscopy. The exfoliation process and roughening of the flat graphite substrate upon exfoliation is directly visualized at the nanoscale on page 4684.

      A novel method for the fabrication of a uniform ultrathin multilayer film composed of alternating poly(p-phenylene vinylene) and reduced graphene oxide layers on a plastic substrate is reported for flexible optoelectronic applications. The ultrathin photodiode exhibits extraordinary optoelectric characteristics, including photocurrent and photoresponsivity; these are among the best values achieved in carbon-based materials.

      2,5-Diaryl-1,3,4-oxadiazole derivatives are shown to be versatile cyclometalating C^N and coordinating N^N ligands for ionic iridium complexes that are fabricated into light-emitting electrochemical cells (LECs). High brightness red emission from a LEC at a driving voltage of 10 V is observed.

    4. Giant Temperature Coefficient of Resistance in Carbon Nanotube/Phase-Change Polymer Nanocomposites (pages 4678–4683)

      Gustavo E. Fernandes, Jin Ho Kim, Ashok K. Sood and Jimmy Xu

      Version of Record online: 5 APR 2013 | DOI: 10.1002/adfm.201300208

      Thumbnail image of graphical abstract

      A carbon nanotube phase-change nanocomposite with a hydrogel achieves giant temperature coefficients of resistance resulting from a phase-transition that directly changes the tunneling potential that electrons experience in moving between nearby nanotubes. The bolometric photoresponses of this material are studied and its giant responses to temperature and humidity give it great potential for sensor applications and uncooled infrared detection.

    5. The Exfoliation of Graphene in Liquids by Electrochemical, Chemical, and Sonication-Assisted Techniques: A Nanoscale Study (pages 4684–4693)

      Zhen Yuan Xia, Sergio Pezzini, Emanuele Treossi, Giuliano Giambastiani, Franco Corticelli, Vittorio Morandi, Alberto Zanelli, Vittorio Bellani and Vincenzo Palermo

      Version of Record online: 17 APR 2013 | DOI: 10.1002/adfm.201203686

      Thumbnail image of graphical abstract

      The different exfoliation routes of graphite to produce graphene by sonication in solvent, chemical oxidation, and electrochemical oxidation are compared. The results obtained show the trade-off between exfoliation speed and preservation of graphene quality. A key step to achieve efficient exfoliation is to couple gas production and mechanical exfoliation on a macroscale with non-covalent exfoliation and preservation of graphene properties on a molecular scale.

    6. Coupling of Micromagnetic and Structural Properties Across the Martensite and Curie Temperatures in Miniaturized Ni-Mn-Ga Ferromagnetic Shape Memory Alloys (pages 4694–4702)

      A. M. Jakob, M. Hennes, M. Müller, D. Spemann and S. G. Mayr

      Version of Record online: 25 APR 2013 | DOI: 10.1002/adfm.201300165

      Thumbnail image of graphical abstract

      Coupling of structural and micromagnetic properties of ferromagnetic Ni-Mn-Ga shape memory thin films is investigated by means of three dimensional numerical simulations and temperature dependent magnetic force microscopy measurements across the martensite and Curie temperatures. A stress-induced magneto-crystalline anisotropy is detected within the austenite phase, which is quantified based on a model of partial flux closure.

    7. Nanosphere Lithography as a Versatile Method to Generate Surface-Imprinted Polymer Films for Selective Protein Recognition (pages 4703–4709)

      Júlia Bognár, Júlia Szűcs, Zsanett Dorkó, Viola Horváth and Róbert E. Gyurcsányi

      Version of Record online: 11 APR 2013 | DOI: 10.1002/adfm.201300113

      Thumbnail image of graphical abstract

      A versatile approach based on nanosphere lithography is proposed to generate surface-imprinted polymers for selective protein recognition. Nanogravimetric measurements demonstrate that the protein (avidin) coating of the nanospheres generates selective recognition sites for avidin on the surface of the PEDOT/PSS film. This methodology coupled with oriented conjugation of the macromolecular template to the nanospheres offers the possibility of site-directed imprinting.

      Novel functionalized three-dimensionally ordered macroporous (3DOM) polymeric materials with well-interconnected and chemically stable structures are created through templating with latex colloidal crystals. These materials display improved CO2 air capture performance compared to a commercially available resin. A versatile strategy is developed to prepare functional porous polymers by colloidal crystal templating, which opens up the use of 3DOM materials for CO2 capture.

    2. Tuning Molecular Adhesion via Material Anisotropy (pages 4729–4738)

      Version of Record online: 8 APR 2013 | DOI: 10.1002/adfm.201300069

      Thumbnail image of graphical abstract

      The collective behaviors of multiple receptor-ligand bonds between a cell and a transversely isotropic matrix are investigated using a two-level model in which the reversible processes of stochastic bond rupture and rebinding at molecular scale and the elastic response of transversely isotropic materials to bond force distributions at continuum scale are integrated.

    3. Template-Free Vibrational Indentation Patterning (VIP) of Micro/Nanometer-Scale Grating Structures with Real-Time Pitch and Angle Tunability (pages 4739–4744)

      Version of Record online: 9 APR 2013 | DOI: 10.1002/adfm.201300293

      Thumbnail image of graphical abstract

      A template-free, high-throughput patterning technique—vibrational indentation-driven patterning (VIP)—realizes continuous, period-tunable fabrication of micro/nanometer-scale gratings by vertical indentations of a vibrating flat tool edge on a moving substrate. By modulating the tool vibration, substrate feeding rate, and the tool tilting angle, the period-variable chirped gratings and angle-tunable blazed gratings can be easily achieved.

      The basic microstructure-dependent energy storage mechanisms of nanostructured MnO2 are investigated via dynamic observation of the growth and in situ probing the mechanical properties by using in situ AFM. A series of dramatic evolutions of nanostructured MnO2 involving progressive nucleation, three-dimensional growth, reversible expansion, proton intercalation induced softening, and self-accommodation phenomena can be correlated to its remarkable energy storage performance.
