  1. High-Resolution Unpixelated Smart Patches with Antiparallel Thickness Gradients of Nanoparticles

    Meital Segev-Bar, Gady Konvalina and Hossam Haick

    Article first published online: 30 JAN 2015 | DOI: 10.1002/adma.201405224

    A new concept for high-resolution sensing of touch/load and location in which the number of pixels can be significantly diminished is presented. The technology is based on a flexible substrate with two parallel gold-nanoparticle strips with antiparallel sensitivity gradients for an unpixelated skin strip. The approach exhibits high location and load resolutions.

  2. Superwettability Controlled Overflow

    Zhichao Dong, Lei Wu, Jianfeng Wang, Jie Ma and Lei Jiang

    Article first published online: 29 JAN 2015 | DOI: 10.1002/adma.201405387

    Superwettability controlled overflow is presented. Superhydrophilicity enhances overflow and superhydrophobicity reduces overflow. The fundamental mechanism for the dynamic interaction between fluids and solid-edges is revealed and several methods for preparing the surfaces of solid-edges with superwettabilities are presented. The insights gained provide new opportunities to achieve controllable dynamic interaction at solid–liquid interfaces for various applications.

  3. Mechanisms for Hydrolysis of Silicon Nanomembranes as Used in Bioresorbable Electronics

    Lan Yin, Amir Barati Farimani, Kyoungmin Min, Nandigana Vishal, Jasper Lam, Yoon Kyeung Lee, Narayana R. Aluru and John A. Rogers

    Article first published online: 27 JAN 2015 | DOI: 10.1002/adma.201404579

    Systematic experimental and theoretical studies of the hydrolysis of silicon nano­membranes at near-neutral pH conditions reveal the roles of anion concentration and temperature. An empirical model captures the dependence of the dissolution rates on key factors, and atomic-level simulations provide insights into the underlying chemistry.

  4. Nanomaterial-Enabled Stretchable Conductors: Strategies, Materials and Devices

    Shanshan Yao and Yong Zhu

    Article first published online: 26 JAN 2015 | DOI: 10.1002/adma.201404446

    Recent progress with regard to nano­material-enabled stretchable conductors and related stretchable devices is reviewed (e.g., capacitive sensors, supercapacitors and electroactive polymer actuators). Focusing on carbon nanomaterials (e.g., carbon nanotubes and graphene) and metal nanomaterials (e.g., metal nanowires and nanoparticles), this review provides fundamental insights into the strategies for developing nanomaterial-enabled highly conductive and stretchable conductors.

  5. Influence of Conversion Material Morphology on Electrochemistry Studied with Operando X-Ray Tomography and Diffraction

    Claire Villevieille, Martin Ebner, Juan Luis Gómez-Cámer, Federica Marone, Petr Novák and Vanessa Wood

    Article first published online: 23 JAN 2015 | DOI: 10.1002/adma.201403792

    X-ray diffraction and X-ray tomography are performed on intermetallic particles undergoing lithiation in a porous electrode. Differences between ensemble phase evolution and that at a single-particle level are explored. It is found that all particles evidence core–shell lithiation; however, particles with internal porosity are more mechanically robust and exhibit less fracture.
