  1. A Miniaturized Flexible Antenna Printed on a High Dielectric Constant Nanopaper Composite

    Tetsuji Inui, Hirotaka Koga, Masaya Nogi, Natsuki Komoda and Katsuaki Suganuma

    Article first published online: 22 DEC 2014 | DOI: 10.1002/adma.201404555

    A high-dielectric-constant and flexible cellulose nanopaper composite is prepared by mixing a small amount of silver nanowires with cellulose nanofibers. The nanopaper antenna is downsized by about a half when using the nanopaper substrate. The nanopaper antenna has potential in wearable wireless communication devices.

  2. Growth of Polypyrrole Ultrathin Films on MoS2 Monolayers as High-Performance Supercapacitor Electrodes

    Hongjie Tang, Jiangyan Wang, Huajie Yin, Huijun Zhao, Dan Wang and Zhiyong Tang

    Article first published online: 22 DEC 2014 | DOI: 10.1002/adma.201404622

    A scalable solution-based approach has been developed to controllably grow PPy ultrathin films on 2D MoS2 monolayers. When these sandwiched nanocomposites are utilized as supercapacitor electrodes, a record high specific capacitance, remarkable rate capability, and improved cycling stability are achieved, offering a feasible solution to create next generation of energy storage device with superior power density and energy density.

  3. Importance of Domain Purity and Molecular Packing in Efficient Solution-Processed Small-Molecule Solar Cells

    Subhrangsu Mukherjee, Christopher M. Proctor, John R. Tumbleston, Guillermo C. Bazan, Thuc-Quyen Nguyen and Harald Ade

    Article first published online: 22 DEC 2014 | DOI: 10.1002/adma.201404388

    Connections are delineated between solar cell performance, charge carrier mobilities, and morphology in a high performance molecular solar cell. The observations show that maximizing relative phase purity and structural order while simultaneously limiting the domain size may be essential for achieving optimal solar cell performances in solution processed small molecule solar cells.

  4. Tunable Rigidity of (Polymeric Core)–(Lipid Shell) Nanoparticles for Regulated Cellular Uptake

    Jiashu Sun, Lu Zhang, Jiuling Wang, Qiang Feng, Dingbin Liu, Qifang Yin, Dongyan Xu, Yujie Wei, Baoquan Ding, Xinghua Shi and Xingyu Jiang

    Article first published online: 22 DEC 2014 | DOI: 10.1002/adma.201404788

    Core–shell nanoparticles (NPs) with lipid shells and varying water content and rigidity but with the same chemical composition, size, and surface properties are assembled using a microfluidic platform. Rigidity can dramatically alter the cellular uptake efficiency, with more rigid NPs more easily passing through cell membranes. The mechanism accounting for this rigidity-dependent cellular uptake is revealed through atomistic-level simulations.

  5. Highly Efficient Tandem Polymer Solar Cells with a Photovoltaic Response in the Visible Light Range

    Zhong Zheng, Shaoqing Zhang, Maojie Zhang, Kang Zhao, Long Ye, Yu Chen, Bei Yang and Jianhui Hou

    Article first published online: 22 DEC 2014 | DOI: 10.1002/adma.201404525

    Thumbnail image of graphical abstract

    Highly efficient polymer solar cells with a tandem structure are fabricated by using two excellent photovoltaic polymers and a highly transparent intermediate recombination layer. Power conversion ­efficiencies over 10% can be realized with a photovoltaic response within 800 nm.
