    A metal–elastomer-foam composite that varies in stiffness, that can change shape and store shape memory, that self-heals, and that welds into monolithic structures from smaller components is presented.

  2. Recent Strategies for Improving the Catalytic Activity of 2D TMD Nanosheets Toward the Hydrogen Evolution Reaction

    Transition-metal dichalcogenide (TMD) nanosheets are promising catalysts for evolving hydrogen. TMDs possess a wide range of electronic and catalytic properties so that important fundamental parameters related to catalysis can be investigated. Recent progress on the study of 2D TMD nanosheets for enhancing their electro- and photocatalytic activity is discussed.

  3. Monitoring of Vital Signs with Flexible and Wearable Medical Devices

    Yasser Khan, Aminy E. Ostfeld, Claire M. Lochner, Adrien Pierre and Ana C. Arias

    Article first published online: 12 FEB 2016 | DOI: 10.1002/adma.201504366

    Flexible and wearable medical devices with applications in human vital signs monitoring are reviewed. A systemic review of the underlying sensing principle, fabrication, data processing, and power requirements of the biosensors is provided. Body temperature, heart rate, respiration rate, blood pressure, pulse oxygenation, and blood glucose sensors are emphasized, as they are ubiquitous in both fitness monitoring and medical diagnostics.

  4. Ultrastrong Bioinspired Graphene-Based Fibers via Synergistic Toughening

    Yuanyuan Zhang, Yuchen Li, Peng Ming, Qi Zhang, Tianxi Liu, Lei Jiang and Qunfeng Cheng

    Article first published online: 12 FEB 2016 | DOI: 10.1002/adma.201506074

    Ultrastrong bioinspired graphene-based fibers are designed and prepared via synergistic toughening of ionic and covalent bonding. The tensile strength reaches up to 842.6 MPa and is superior to all other reported graphene-based fibers. In addition, its electrical conductivity is as high as 292.4 S cm−1. This bioinspired synergistic toughening strategy supplies new insight toward the construction of integrated high-performance graphene-based fibers in the near future.

  5. On-Surface Synthesis of Atomically Precise Graphene Nanoribbons

    Leopold Talirz, Pascal Ruffieux and Roman Fasel

    Article first published online: 12 FEB 2016 | DOI: 10.1002/adma.201505738

    Surface-assisted polymerization and cyclodehydrogenation of molecular building blocks provides a route toward atomically precise graphene nanoribbons, which combines the outstanding electronic properties of graphene with a bandgap that is sufficiently large for digital-logic applications. This report covers the progress made in understanding the on-surface reactions, in synthesizing atomically precise nanoribbons of various shapes, and in measuring their properties.
