  1. Cellulose Nanocrystal Aerogels as Universal 3D Lightweight Substrates for Supercapacitor Materials

    Xuan Yang, Kaiyuan Shi, Igor Zhitomirsky and Emily D. Cranston

    Article first published online: 2 SEP 2015 | DOI: 10.1002/adma.201502284

    Chemically cross-linked cellulose nanocrystal aerogels represent a versatile and universal substrate on which to prepare lightweight hybrid materials. In situ incorporation of polypyrrole nanofibers, polypyrrole-coated carbon nanotubes, and manganese dioxide nanoparticles in the aerogels gives flexible 3D supercapacitor devices with excellent capacitance retention, low internal resistance, and fast charge-discharge rates.

  2. Core–Shell MnSe@Bi2Se3 Fabricated via a Cation Exchange Method as Novel Nanotheranostics for Multimodal Imaging and Synergistic Thermoradiotherapy

    Guosheng Song, Chao Liang, Hua Gong, Meifang Li, Xianchuang Zheng, Liang Cheng, Kai Yang, Xiqun Jiang and Zhuang Liu

    MnSe@Bi2Se3 core–shell nanostructures with highly integrated imaging and therapy functions are fabricated by a simple cation exchange method. Using those nanoparticles as a theranostic agent, a promise concept is further demonstrated to enhance conventional radiotherapy by: i) using X-ray absorbing agents to locally concentrate radiation energy and ii) employing near-infrared-light-triggered photothermal therapy to overcome hypoxia-associated radioresistance.

  3. Strengthened Magnetoresistive Epoxy Nanocomposite Papers Derived from Synergistic Nanomagnetite-Carbon Nanofiber Nanohybrids

    Hongbo Gu, Jiang Guo, Huige Wei, Shimei Guo, Jiurong Liu, Yudong Huang, Mojammel Alam Khan, Xuefeng Wang, David P. Young, Suying Wei and Zhanhu Guo

    Article first published online: 2 SEP 2015 | DOI: 10.1002/adma.201501728

    Novel papers based on epoxy nano­composites with magnetite and carbon nano­fiber (CNF) nanohybrids, without any surface modification to the nanofillers, show combined conductive, magnetic, and magnetoresistive properties. Negative magnetoresistance (MR) is observed in synthesized epoxy nanohybrid papers for the first time. These papers have potential applications for flexible electronics, magnetoresistive sensors, and the printing industry.

  4. Subtle Balance Between Length Scale of Phase Separation and Domain Purification in Small-Molecule Bulk-Heterojunction Blends under Solvent Vapor Treatment

    Miaomiao Li, Feng Liu, Xiangjian Wan, Wang Ni, Bin Kan, Huanran Feng, Qian Zhang, Xuan Yang, Yunchuang Wang, Yamin Zhang, Yan Shen, Thomas P. Russell and Yongsheng Chen

    Article first published online: 2 SEP 2015 | DOI: 10.1002/adma.201502645

    A series of solvents with different solubilities for DR3TBDTT and PC71BM, and different boiling points, are used for solvent vapor annealing (SVA) treatment to systematically investigate the solvent–morphology–performance relationship. The presence of solvent molecules inside bulk-heterojunction (BHJ) thin films promotes the mobility of both donor and acceptor molecules, leading to crystallization and aggregation, which are important in modulating morphology.

  5. Light-Emitting Devices: Enhancing Optical Out-Coupling of Organic Light-Emitting Devices with Nanostructured Composite Electrodes Consisting of Indium Tin Oxide Nanomesh and Conducting Polymer (Adv. Mater. 33/2015) (page 4806)

    Chien-Yu Chen, Wei-Kai Lee, Yi-Jiun Chen, Chun-Yang Lu, Hoang Yan Lin and Chung-Chih Wu

    Article first published online: 1 SEP 2015 | DOI: 10.1002/adma.201570219

    Nanostructured transparent composite electrodes consisting of perforated high-index conducting metal oxides and low-index conducting polymers are developed by C.-C. Wu and co-workers on page 4883. They are useful for effectively enhancing the optical out-coupling of organic light-emitting devices (OLEDs), yielding a very high OLED external quantum efficiency of nearly 62% when combined with the external extraction scheme.
