    Carbon–silica composite thin-films to produce electrode devices that withstand more than a hundred electrochemical measurements in liquid solutions without loss of performance thanks to the strong adhesion of the silica component to the substrate. These devices are applied in electrochemical sensing but can also find application in energy storage and electrocatalysis.

    A diazonium-induced anchoring process can be applied where a uniform thickness of organic coating is required on a variety of substrates. This process is used to devise a completely aqueous route of chemical metallization of microelectromechanical systems (MEMS) structures. The process is simple, cost-effective, manufacturable, and can potentially replace the organic-based silanization process for metallization in MEMS.

  3. Roll-to-Roll Fabrication of Flexible Orientated Graphene Transparent Electrodes by Shear Force and One-Step Reducing Post-Treatment

    Flexible transparent electrodes (FTEs) are fabricated via shearing force of roll-to-roll process. The shear force of slot-die print is creatively applied to form thin layer of reduced graphene oxide. The hydroiodic acid post-treatment can remove polystyrene sulfonate as well as reduce graphene oxide to enhance conductivity. The FTEs are faultlessly employed in polymer solar cells with power conversion efficiency of 8.32% based on 1.01 cm2.

  4. Morphology-Induced TiO2 Bandgap Change for Super Rapid Treatment of Dye Wastewater under Visible Light

    Ruixiang Qu, Na Liu, Yuning Chen, Weifeng Zhang, Guoxiang Zhu, Qingdong Zhang and Lin Feng

    A novel morphology-induced TiO2 nano­wire-based mesh is fabricated by a simple hydrothermal reaction. The special nano­wire morphology reduces the bandgap of TiO2, and the Cu(OH)2 substrate provides the material with higher light absorption efficiency. Combined the special wettability and the excellent photoelectric property of TiO2 nanowires, such material can realize oil removal and dye degradation under visible light.

  5. Manipulating Superparamagnetic Microparticles with an Electromagnetic Needle

    Zoran Cenev, Hongbo Zhang, Veikko Sariola, Antti Rahikkala, Dongfei Liu, Hélder A. Santos and Quan Zhou

    Version of Record online: 16 OCT 2017 | DOI: 10.1002/admt.201700177

    A manipulation technique employing robotized electromagnetic needle for fast, deterministic, and precise pick-and-place manipulation of individual superparamagnetic microparticles is presented. By controlling the localized magnetic field and the position of the needle, a single particle can be selectively picked from a particle population, and placed at desired locations within sub-micrometer precession.
