      Porous Materials: Copper Conversion into Cu(OH)2 Nanotubes for Positioning Cu3(BTC)2 MOF Crystals: Controlling the Growth on Flat Plates, 3D Architectures, and as Patterns (Adv. Funct. Mater. 14/2014) (page 1961)

      Controlling metal–organic framework (MOF) growth on different substrates is crucial for device fabrication. An Australian–Japanese collaboration between M. Takahashi, P. Falcaro, and co-workers demonstrates on page 1969 how MOF coatings on flat plates, 3D surfaces, and patterns can be fabricated using a facile, two-step conversion process at room temperature with aqueous/alocholic solutions. Using copper substrates, nanotubes are grown and then quickly converted to MOF crystals, and MOF patterns are fabricated using sunlight.

      Luminescent ZnO quantum dots are prepared by G. Bacher, U. Kortshagen, and co-workers in a nonthermal plasma reactor operated with a high frequency source. Quantum dots with diameters down to 2.1 nm are achieved, exhibiting exceptional quantum yields of up to 60%. On page 1988, the mechanism for the dominating green–yellow emission is discussed and the influence of oxygen species on the emission spectrum is investigated.

      Porous Scaffolds: Bioinspired Scaffolds with Varying Pore Architectures and Mechanical Properties (Adv. Funct. Mater. 14/2014) (page 2108)

      Michael M. Porter, Russ Imperio, Matthew Wen, Marc A. Meyers and Joanna McKittrick

      Version of Record online: 4 APR 2014 | DOI: 10.1002/adfm.201470091

      This image was created by freeze casting TiO2 powders, using ice as a template to control the architectural morphology of the scaffold. Such bioinspired scaffolds with equal porosity but different pore architectures exhibit compressive mechanical properties that change as a function of the pore morphology. On page 1978, the ceramic scaffolds are prepared by M. M. Porter et al. by freeze casting aqueous slurries with different soluble additives to alter the viscosity, pH, or alcohol concentration.

      HKUST-1 [Cu3(BTC)2] coatings with a good adhesion are homogeneously fabricated on copper metal plates, 3D objects, and patterns. The MOFs are converted from any metallic Cu object via Cu(OH)2 nanotubes at room temperature in approximately 30 min using an aqueous ethanolic mixture. The conversion mechanism from copper hydroxide nanotubes into Cu3(BTC)2 is revealed by electron microscopy time-course monitoring.

    2. Bioinspired Scaffolds with Varying Pore Architectures and Mechanical Properties (pages 1978–1987)

      Bioinspired scaffolds with equal porosity, but different pore architectures exhibit compressive mechanical properties that change as a function of the pore morphology. The scaffolds are fabricated by freeze casting with different soluble additives to alter the viscosity, pH, or alcohol concentration. A simplified Euler buckling analysis predicts the strength of the scaffolds as a function of the pore aspect ratio.

      The orientation and organization of semiconducting polymer at the polymer/(gate dielectric) interface has a strong influence on OFET hole mobilities. For poly(3-alkylthiophene) thin films, both from chlorobenzene and from nanofiber dispersions, orientation and OFET mobility are compared for the interfaces formed at bare SiO2 and at air (then laminated on bare SiO2), that is, at two extremes of the polarity scale.

      An effective way of using ionic liquid as a gate dielectric as well as a pressure medium is presented to tune the transport of an exemplary polymer semiconductor, poly(2,5-bis(3-tetradecyl-thiophene-2-yl)thieno[3,2-b]thiophene) (pBTTT-C14). By combining both gating and pressuring, the room temperature conductivity of the polymer film is dramatically enhanced and a crossover of transport properties is observed from one-dimensional to three-dimensional hopping at low temperatures.

      Ordered mesoporous carbon is proposed to be directly coated on 3D graphene foam. After further coating with 1D silver nanowires, the obtained Ag NWs/3D-graphene foam/OMC (Ag-GF-OMC) exhibits exceptional electrical conductivity (up to 762 S cm−1) and mechanical robustness. As a result, it can act as a new type of flexible electrode for high performance supercapacitors.

      Donor–accepotor (DA)-type deep-blue fluorescent compounds are synthesized. Twisted conformations of the two anthracene units in the compounds effectively prevent π-conjugation. The compounds show deep-blue photoluminescence (PL) with a high quantum efficiency, almost independent of solvent polarity. The weak DA-type compound exhibits an external quantum efficiency >10% and deep-blue emission with CIE (0.15, 0.06) in a light-emitting device.

      Sphere, cube, and ellipsoid-like Mn3O4 nanoparticles integrated with nitrogen-doped graphene are synthesized and used as oxygen reduction reaction (ORR) catalysts. The catalyst shape dependence on the ORR activity is investigated, and the hybrid of ellipsoidal Mn3O4/N-graphene exhibits the best ORR activity which may be related to the dominant (001) facets in Mn3O4 nanocrystals.
