    An ultrahigh performance MoS2 photodetector with high photoresponsivity (1.94 × 106 A W–1) and detectivity (1.29 × 1012 Jones) under 520 nm and 4.63 pW laser exposure is demonstrated. This photodetector is based on a methyl-ammonium lead halide perovskite/MoS2 hybrid structure with (3-aminopropyl)triethoxysilane doping. The performance degradation caused by moisture is also minimized down to 20% by adopting a new encapsulation bilayer of octadecyltrichlorosilane/polymethyl methacrylate.

  2. Liquid Exfoliated Natural Silk Nanofibrils: Applications in Optical and Electrical Devices

    A method to directly extract silk nanofibrils from native silk fibers at the single nanofibrils scale is reported. The resulting silk nanofibrils, which retain structural features and physical properties of native silk fibers, show potential utility in optical and electronic devices.

  3. Building Materials from Colloidal Nanocrystal Arrays: Preventing Crack Formation during Ligand Removal by Controlling Structure and Solvation

    Santosh Shaw, Bin Yuan, Xinchun Tian, Kyle J. Miller, Bryan M. Cote, Julien L. Colaux, Andrea Migliori, Matthew G. Panthani and Ludovico Cademartiri

    Crack-free, ligand-free, phase-pure nanostructured solids, using colloidal nanocrystals as precursors, are fabricated by a scalable and facile approach. Films produced by this approach have conductivities comparable to those of bulk crystals over more than 1 cm (1.370 S cm−1 for PbS films).

  4. Macroporous Interconnected Hollow Carbon Nanofibers Inspired by Golden-Toad Eggs toward a Binder-Free, High-Rate, and Flexible Electrode

    Yan-Bin Yin, Ji-Jing Xu, Qing-Chao Liu and Xin-Bo Zhang

    Inspired by the favorable structure and shape of golden-toad eggs, a self-standing macroporous active carbon fiber electrode is designed and fabricated via a facile and scalable strategy. After being decorated with ruthenium oxide, it endows Li–O2 batteries with superior electrochemical performances.

  5. Rotary Actuators Based on Pneumatically Driven Elastomeric Structures

    Xiangyu Gong, Ke Yang, Jingjin Xie, Yanjun Wang, Parth Kulkarni, Alexander S. Hobbs and Aaron D. Mazzeo

    Version of Record online: 27 JUN 2016 | DOI: 10.1002/adma.201600660

    Unique elastomeric rotary actuators based on pneumatically driven peristaltic motion are demonstrated. Using silicone-based wheels, these motors enable a new class of soft locomotion not found in nature, which is capable of withstanding impact, traversing irregular terrain, and operating in water. For soft robotics, this work marks progress toward providing torque without bending actuators.
