      Sang Jun Sim and co-workers demonstrate on page 1265 the specific recognition of pointmutated promoter by RNA polymerase. The interactions between promoter and RNA polymerase are monitored using Rayleigh light scattering on gold nanoparticles. Using a darkfield microscope, the individual gold nanoparticles can be visualized as the bright colored spots (red, green, or orange in the cover image) by light scattering. Binding of RNA polymerase on the surface of a AuNP is quantitatively detected by LSPR (localized surface plasmon resonance) maximum wavelength shift.

    1. Macroscopic Nanoparticle Ribbons and Fabrics (pages 1248–1253)

      Dong Yun Lee, Jonathan T. Pham, Jimmy Lawrence, Cheol Hee Lee, Cassandra Parkos, Todd Emrick and Alfred J. Crosby

      Version of Record online: 12 NOV 2012 | DOI: 10.1002/adma.201203719

      Thumbnail image of graphical abstract

      Nanoparticle (NP) ribbons and fabrics are fabricated using a facile, evaporation-driven approach that directs NP assembly at a liquid meniscus, which is constrained using principles of elastocapillarity with uniform molecular dimensions over large lateral distances. This results in the creation of uniform NP ribbons of nanoscale height and sub-micrometer width, without structural defects, across large, macroscopic areas (i.e., several square centimeters).

    2. Design of Battery Electrodes with Dual-Scale Porosity to Minimize Tortuosity and Maximize Performance (pages 1254–1258)

      Version of Record online: 7 DEC 2012 | DOI: 10.1002/adma.201204055

      Thumbnail image of graphical abstract

      Electrode pore topology can be tuned to improve battery power without sacrificing energy density. One effective design has “dual-scale” porosity, combining aligned channels and a porous matrix. Iterated co-extrusion yields sintered cathodes of this architecture, with channel spacing tunable down to ∼15 μm. Results show that net tortuosity is reduced compared to homogeneous porosity, significantly improving cell-discharge rates.

      A variety of gold nanostructures is fabricated using a novel fabrication approach that combines direct laser writing and electron-beam lithography. While preserving the nanoscopic feature sizes achievable with electron-beam lithography, this approach allows the realization of out-of plane metallic nanostructures, and thereby opens up new opportunities for metamaterials, nanoantennas, and nanoplasmonics. More details can be found in the article by Isabelle Staude and co-workers on page 1260.

      We propose a novel hybrid fabrication approach that combines direct laser writing with a subsequent electron-beam lithography step. This approach allows realizing out-of-plane plasmonic nanostructures with truly nanoscopic feature sizes. The excellent quality of the obtained structures is evidenced by optical characterization of upright-standing split-ring resonator arrays fabricated along these lines.

    2. Real-Time, Sensitive, and Specific Detection of Promoter-Polymerase Interactions in Gene Transcription Using a Nanoplasmonic Sensor (pages 1265–1269)

      Real-time, sensitive and specific analysis of gene transcription: The interactions between promoter and RNA polymerase that lead to gene transcription are monitored using Rayleigh light scattering of gold nanoparticle. We can simply detect which base pair of point-mutated promoter is important for the specific recognition by RNA polymerase. This is the first attempt to analyze transcription activity, based on the optical property of single gold nanoparticle.

    3. Graphene-Stabilized Silver Nanoparticle Electrochemical Electrode for Actuator Design (pages 1270–1274)

      Version of Record online: 26 NOV 2012 | DOI: 10.1002/adma.201203655

      Thumbnail image of graphical abstract

      An electrochemical actuator based on a graphene-stabilized silver-nanoparticle (AgNP) electrode is presented. Owing to the actuation characteristics — persistence, fast strain rate, and wide frequency response — the strategy of hybridizing reduced graphene oxide (RGO) and AgNPs is believed to be of great value for developing more RGO/metal hybrid–based electrochemical actuators or sensors for various applications.

    4. Spider Silk: Super Material or Thin Fibre? (pages 1275–1279)

      Thumbnail image of graphical abstract

      This work challenges the popular view that silk has exceptional intrinsic mechanical properties of strength and toughness. All polymer fibres are shown to follow one fracture mechanics relationship between failure strength and the ratio of elastic modulus to fibre diameter. Predictive structure–property relations are derived for strength and fracture toughness, and small diameter plays a large part in silk properties.

      Nanoporous gold made by alloy corrosion can be impregnated with epoxy resin to produce a novel, polymer-based nanocomposite material that is reinforced by an interconnected network of high-strength metal nanostructures. The composite has a near-metallic electric conductivity, is ductile in tension and compression and its strength considerably exceeds that of each of the individual constituent phases.

    6. Evolutionary Selection Growth: Towards Template-Insensitive Preparation of Single-Crystal Layers (pages 1285–1289)

      Benjamin Leung, Jie Song, Yu Zhang and Jung Han

      Version of Record online: 10 DEC 2012 | DOI: 10.1002/adma.201204047

      Thumbnail image of graphical abstract

      A method for growth of large-area, selectively defined, single-crystal semiconductor material on an amorphous template has been demonstrated. In two steps, the degrees of freedom in crystal orientation have been reduced by the principle of evolutionary selection, starting with the deposition of a textured aluminum nitride seed on SiO2, and the longitudinal growth of gallium nitride single crystals. This concept enables the integration of semiconductor materials with a new range of substrates.

      An integrated organic temperature sensor with 10 bits dynamic range is reported by Paddy K.L. Chan and co-workers on page 1291. Inside the sensor, silver nanoparticles are inserted into the pentacene to enhance the temperature sensitivity of the thermistor. The high dynamic range of the sensor is attributed to the signal amplification by the integrated device.

      A systematic study of the role of the insulator layer on rectification performance in metal–insulator–metal structures is reported. Four different MIM systems with Nb/Pt metal pairs and Nb2O5, TiO2, Al2O3, MgO as the insulator candidates are investigated based on an empirical hypothesis. As per the hypothesis and experimental verification, several prospective MIM systems such as Sm/ZrO2/Pt and Hf/TiO2/Pt are identified and a MIM materials-space is constructed.

      The assembly of ligand-stripped CdSe nanocrystals into hierarchical mesoporous architectures via polymer templating is reported. The nanocrystal-based porous CdSe combines micropores, created at the juncture between nanocrystals, and mesopores, created by the polymer template, to yield a high surface-area material with accessible pores, while preserving the optical and electronic properties of quantum confined CdSe nanocrystals.

    6. Nanoscale Dynamics of Superdomain Boundaries in Single-Crystal BaTiO3 Lamellae (pages 1323–1330)

      Pankaj Sharma, Raymond G. P. McQuaid, Leo J. McGilly, J. Marty Gregg and Alexei Gruverman

      Version of Record online: 7 JAN 2013 | DOI: 10.1002/adma.201203226

      Thumbnail image of graphical abstract

      In situ piezoresponse force microscopy (PFM) imaging reveals highly non-linear kinetics of the superdomain boundary separating two a-c-domain bundles in BaTiO3 lamellae. It is suggested that this behavior is caused by an unscreened depolarizing field of newly switched domains that counter balances the driving force from the applied electric field.

      Version of Record online: 29 NOV 2012 | DOI: 10.1002/adma.201203849

      Thumbnail image of graphical abstract

      The stress-induced photo-luminescence response of tetrapodal shaped ZnO filler embedded in a silicone elastomer is used to demonstrate a novel concept for self-reporting materials. Applied tensile stress can be followed in composites with low and high filler fractions by measuring the photoluminescence response of the T-ZnO. The deformation of the interlocked ZnO network appears to be essential for the self-reporting mechanism.

      Hierarchical carbon electrodes with highly aligned carbon nanotube (CNT) fibrils are fabricated, and it is demonstrated that these electrodes, with aligned pores, can significantly enhance the cyclability and rate capability of Li−O2 batteries. The highly aligned pore structure enables good accessibility of oxygen to the inner electrode, which leads to a uniform deposition of discharge products on the individual CNTs.
