      On page 3525, Susumu Kitagawa and co-workers demonstrate a new porous coordination polymer, in which the uniform 1D channel and open metal sites lead to excellent methane separation capability towards carbon dioxide and C2 hydrocarbons at ambient temperature. More importantly, its high water- and acid/alkaline-resistance properties will pave the way for practical use for methane purification in the future.

      High-performance, top-gated, organic, nanofloating gate memory (NFGM) devices fabricated using spatially well-distributed metallic nanoparticles as a floating gate and dielectrics with long charge relaxation properties are reported by Kang-Jun Baeg, Yong-Young Noh, Dong-Yu Kim, and co-workers on page 3503. The organic NFGM devices show wide memory windows, a high on/off current ratio, and quasi-permanent retention characteristics. The 256-bit NFGM array is also fabricated successfully on a flexible polyethylene naphthalate (PEN) substrate.

    1. A Fabricated siRNA Nanoparticle for Ultralong Gene Silencing In Vivo (pages 3488–3493)

      Seung Koo Lee and Ching-Hsuan Tung

      Version of Record online: 18 FEB 2013 | DOI: 10.1002/adfm.201202777

      Thumbnail image of graphical abstract

      An ultralong siRNA gene silencing effect is achieved in cells and in animal using a functionalized siRNA nanoparticle that consists of multiple siRNA and degradable polypeptide layers. Due to the slow degradation through the layers, the particles continuously release siRNA and the in vivo gene silencing effect is consistent for more than 3 weeks with only a single treatment.

    2. Self-Supporting Graphene Hydrogel Film as an Experimental Platform to Evaluate the Potential of Graphene for Bone Regeneration (pages 3494–3502)

      A self-supporting graphene hydrogel film prepared by a simple vacuum filtration technology is used as a unique experimental platform to study how graphene interacts with biological tissues both in vitro and in vivo. This graphene-based bulk material appears to be highly biocompatible, biodegradable, and osteoinductive, demonstrating graphene's potential for bone regenerative medicine.

      Thumbnail image of graphical abstract

      Highly stable top-gated organic nano-floating-gate memory (NFGM) devices with quasi-permanent retention characteristics are fabricated using an n-type conjugated polymer. The best polymer NFGM devices show excellent memory-related characteristics along with a wide memory window, a high on-off current ratio, and a long retention time.

    4. Hierarchical Layered Double Hydroxide Microspheres with Largely Enhanced Performance for Ethanol Electrooxidation (pages 3513–3518)

      Mingfei Shao, Fanyu Ning, Jingwen Zhao, Min Wei, David G. Evans and Xue Duan

      Thumbnail image of graphical abstract

      Hierarchical MgFe-layered double hydroxide (LDH) microspheres with tunable interior structure (hollow, yolk−shell, and solid) are synthesized by a facile and cost-effective surfactant-templated method. The resulting hollow LDH microspheres yields largely enhanced activity as well as robust durability towards ethanol electro-oxidation, owing to the significantly improved mass transport and faradaic redox reaction.

      A new dicyanovinyl-substituted diketopyrrolopyrrole (DPP)-based small molecule, DPP-T-DCV, shows outstanding electron mobility (μe) in solution-processed single-crystal OFETs (SC-OFETs). The molecular structure of DPP-T-DCV, SC-OFETs device structure, and atomic force microscopy images of the film surface of the DPP-T-DCV crystal device are shown. SC-OFETs exhibit μe as high as 0.96 cm2 V−1 s−1 with on/off current ratio of ≈105.

    6. High CO2/CH4 and C2 Hydrocarbons/CH4 Selectivity in a Chemically Robust Porous Coordination Polymer (pages 3525–3530)

      Jingui Duan, Masakazu Higuchi, Satoshi Horike, Maw Lin Foo, Koya Prabhakara Rao, Yasutaka Inubushi, Tomohiro Fukushima and Susumu Kitagawa

      Version of Record online: 26 FEB 2013 | DOI: 10.1002/adfm.201203288

      A new porous coordination polymer, ([La(BTB)H2O]·solvent (1⊃guest)), exhibits high CH4 separation capability toward CO2 and C2 hydrocarbons at room temperature. In particular, it shows good water and chemical stability and is stable at pH = 14 at 100 °C.

    7. Dynamic Doping in Planar Ionic Transition Metal Complex-Based Light-Emitting Electrochemical Cells (pages 3531–3538)

      Sebastian B. Meier, Stephan van Reenen, Bastien Lefevre, David Hartmann, Henk J. Bolink, Albrecht Winnacker, Wiebke Sarfert and Martijn Kemerink

      Version of Record online: 26 FEB 2013 | DOI: 10.1002/adfm.201202689

      Thumbnail image of graphical abstract

      A combination of fluorescence and scanning Kelvin probe microscopy is used to gain insight into the operational mechanism of planar ionic transition metal complex-based light-emitting electrochemical cells. Quenching of the photoluminescence in the interelectrode gap in accord with a sharp potential drop far away from the electrodes confirm an electrochemical doping mechanism, which results in the formation of a light-emitting p-i-n junction.

      Thermal polymerization of a conjugated polymer is performed directly on the device electrode using solution-processable monomers. On page 3549, W. G. Skene and co-workers report that the resulting immobilized polymer is electroactive and it is reversibly switched electrotrochemically between its colored states. The polymer is successfully used as the electrochromic layer in a working device with repeated color switching.

    2. Substantial Recoverable Energy Storage in Percolative Metallic Aluminum-Polypropylene Nanocomposites (pages 3560–3569)

      Lisa A. Fredin, Zhong Li, Michael T. Lanagan, Mark A. Ratner and Tobin J. Marks

      Version of Record online: 7 FEB 2013 | DOI: 10.1002/adfm.201202469

      Thumbnail image of graphical abstract

      Al-polypropylene nanocomposites are promising pulse-power capacitor materials, with resistivities of ≈ 1012–1015 Ω·cm, low dielectric loss in the 100 Hz–1 MHz frequency range, and recoverable energy storage as high as 14.4 J/cm3. These conductive-insulator composites obey the percolation law for two-phase composites, reaching maximum permittivity values, ϵr, as high as 15.4 before the percolation threshold volume fraction, vf = 0.16.

    3. Graphene-Based Mesoporous SnO2 with Enhanced Electrochemical Performance for Lithium-Ion Batteries (pages 3570–3576)

      Sheng Yang, Wenbo Yue, Jia Zhu, Yu Ren and Xiaojing Yang

      Version of Record online: 18 FEB 2013 | DOI: 10.1002/adfm.201203286

      Thumbnail image of graphical abstract

      A graphene-based mesoporous SnO2 composite is prepared via in situ growth of mesoporous SnO2 on the graphene surface using cetyltrimethylammonium bromide (CTAB) as a template. Because of the high specific surface area and stable mesostructure of SnO2 nanocrystalline on graphene, it displays higher reversible capacity, better cycle performance, and better rate capability compared to mesoporous SnO2 and graphene-based non-porous SnO2.

    4. High-Concentration Aqueous Dispersions of MoS2 (pages 3577–3583)

      Yagang Yao, Lorenzo Tolentino, Zhongzheng Yang, Xiaojuan Song, Wen Zhang, Yongsheng Chen and Ching-ping Wong

      Version of Record online: 27 FEB 2013 | DOI: 10.1002/adfm.201201843

      Thumbnail image of graphical abstract

      The lack of a reliable large-scale production method inhibits practical applications of MoS2 nanosheets. To address this, a facile, efficient, and scalable method for the fabrication of high-concentration aqueous dispersion of MoS2 nanosheets using combined grinding and sonication is developed. The exfoliation process establishes a new paradigm in the top-down fabrication of 2D nanosheets in aqueous solution.

    5. Nongeminate Recombination and Charge Transport Limitations in Diketopyrrolopyrrole-Based Solution-Processed Small Molecule Solar Cells (pages 3584–3594)

      Christopher M. Proctor, Chunki Kim, Dieter Neher and Thuc-Quyen Nguyen

      Version of Record online: 25 FEB 2013 | DOI: 10.1002/adfm.201202643

      Thumbnail image of graphical abstract

      Charge transport and voltage-dependent recombination losses are studied in two diketopyrrolopyrrole (DPP)-based solution-processed small molecule bulk heterojunction solar cells. Light intensity and impedance spectroscopy measurements probe the influence of nongeminate recombination losses in both systems. Further analysis suggests the increase in fill factor observed in the bis-DPP system is a direct result of the higher hole mobility.
