    Three-dimensional microstructures of hat, cone, pillar, and spindle shapes are prepared by Y. Song and co-workers based on interface manipulation by inkjet printing. On page 1900, the 3D morphologies are precisely controlled by the 2D interfacial properties of the substrate. Accurately positioned and oriented patterning of 3D arrays are facilely achieved, demonstrating the high controllability of this strategy to fabricate uniform 3D microstructures on a large scale. This advance will present significant insight and promising applications in controllable 3D manufacturing.

    Nanostructures: Gold Nanorod@TiO2 Yolk-Shell Nanostructures for Visible-Light-Driven Photocatalytic Oxidation of Benzyl Alcohol (Small 16/2015) (page 1861)

    Ang Li, Peng Zhang, Xiaoxia Chang, Weiting Cai, Tuo Wang and Jinlong Gong

    Selective oxidation of alcohols to corresponding aldehydes and ketones is an essential process for the synthesis of various chemicals. J. Gong and co-workers describe the design and synthesis of gold nanorod@TiO2 yolk–shell catalysts via an improved silica template method as an efficient visible light-driven photocatalyst. On page 1892, with a hollow TiO2 shell and a tunable cylindrical gold core, the catalyst exhibits a high surface area and wide absorption range from UV to NIR. A remarkable photochemical activity is obtained when such catalyst applied to the oxidation of benzyl alcohol.

    Sensors: Mimosa-Inspired Design of a Flexible Pressure Sensor with Touch Sensitivity (Small 16/2015) (page 1885)

    Bin Su, Shu Gong, Zheng Ma, Lim Wei Yap and Wenlong Cheng

    Article first published online: 20 APR 2015 | DOI: 10.1002/smll.201570093

    A new bioinspired strategy to fabricate flexible pressure sensors with touch sensitivity is reported by B. Su, W. Cheng, and co-workers on page 1886. Inspired by mimosa - a plant can close its leaves under external stimuli - a simple, efficient, low-cost, and scalable direct-molding method is proposed to yield sensitive pressure sensors, leading to the fabrication of artificial touch-sensing “mimosa leaves”. This mimosa-inspired approach opens a new route to fabricating flexible pressure sensors in a cost-effective and scalable manner.
