  1. Magnetic-Mechanical-Electrical-Optical Coupling Effects in GaN-Based LED/Rare-Earth Terfenol-D Structures

    Mingzeng Peng, Yan Zhang, Yudong Liu, Ming Song, Junyi Zhai and Zhong Lin Wang

    Article first published online: 2 SEP 2014 | DOI: 10.1002/adma.201402824

    In this work, a multi-field coupling structure is designed and investigated, which combines GaN-based optoelectronic devices and Terfenol-D. The abundant coupling effects and multifunctionalities among magnetics, mechanics, electrics, and optics have been investigated by a combination of nonmagnetic GaN-based piezoelectronic optoelectronic characteristics and giant magnetomechanical properties of Terfenol-D. A few potential new areas of studies are proposed.

  2. Hierarchical Li1.2Ni0.2Mn0.6O2 Nanoplates with Exposed {010} Planes as High-Performance Cathode Material for Lithium-Ion Batteries

    Lai Chen, Yuefeng Su, Shi Chen, Ning Li, Liying Bao, Weikang Li, Zhao Wang, Meng Wang and Feng Wu

    Article first published online: 2 SEP 2014 | DOI: 10.1002/adma.201402541

    Hierarchical Li1.2Ni0.2Mn0.6O2 nanoplates with exposed {010} planes are designed and synthesized. In combination with the advantages from the hierarchical archi­tecture and the exposed electrochemically active {010} planes of layered materials, this material satisfies both efficient ion and electron transport and thus shows superior rate capability and excellent cycling stability.

  3. Switchable Water-Adhesive, Superhydrophobic Palladium-Layered Silicon Nanowires Potentiate the Angiogenic Efficacy of Human Stem Cell Spheroids

    Jungmok Seo, Jung Seung Lee, Kihong Lee, Dayeong Kim, Kisuk Yang, Sera Shin, Chandreswar Mahata, Hwae Bong Jung, Wooyoung Lee, Seung-Woo Cho and Taeyoon Lee

    Article first published online: 2 SEP 2014 | DOI: 10.1002/adma.201402273

    A switchable water-adhesive, super­hydrophobic nanowire surface is developed for the formation of functional stem cell spheroids. The sizes of hADSC spheroids are readily controllable on the surface. Our surface increases cell-cell and cell-matrix interaction, which improves viability and paracrine secretion of the spheroids. Accordingly, the hADSC spheroids produced on the surface exhibit significantly enhanced angiogenic efficacy.

  4. Controlled Functionalization of Carbonaceous Fibers for Asymmetric Solid-State Micro-Supercapacitors with High Volumetric Energy Density

    Dingshan Yu, Kunli Goh, Qiang Zhang, Li Wei, Hong Wang, Wenchao Jiang and Yuan Chen

    Article first published online: 2 SEP 2014 | DOI: 10.1002/adma.201403061

    A 1.8 V asymmetric solid-state flexible micro-supercapacitor is designed with one MnO2-coated reduced graphene oxide/single walled carbon nanotube (rGO/SWCNT) composite fiber as positive electrode and one nitrogen-doped rGO/SWCNT fiber as negative electrode, which demonstrates ultrahigh volumetric energy density, comparable to some thin-film lithium batteries, along with high power density, long cycle life, and good flexibility.

  5. All-Organic and Fully-Printed Semitransparent Photodetectors based on Narrow Bandgap Conjugated Molecules

    Giuseppina Pace, Andrea Grimoldi, Dario Natali, Marco Sampietro, Jessica E. Coughlin, Guillermo C. Bazan and Mario Caironi

    Article first published online: 2 SEP 2014 | DOI: 10.1002/adma.201402918

    Thumbnail image of graphical abstract

    All-organic, fully-printed and semitransparent photodetectors with a broad wavelength band response, based on a ternary blend comprising narrow band-gap small molecules, are demonstrated. The ternary blend with a semiconducting polymer allows for the optimal printing of small molecules, suppressing strong phase segregation, and uncontrolled crystallization. The insertion of a suitable interlayer enables the adoption of polymer transparent top and bottom printed electrodes, thus making light detection possible from both device sides.
