  1. Cellulose Sponge with Superhydrophilicity and High Oleophobicity Both in Air and under Water for Efficient Oil–Water Emulsion Separation

    Junjun Chen, Yingxin Zhang, Cheng Chen, Mengya Xu, Gang Wang, Zhixiang Zeng, Liping Wang and Qunji Xue

    Amphiphilic molecular brushes are grafted on cellulose sponges to solve the contradictory relation of hydrophilicity and oleophobicity and improve oil/water selective wettability and fouling resistance. Besides, stable superhydrophilicity and high oleophobicity in air are exhibited in the modified porous cellulose sponges with textured surfaces.

  2. Extreme Toughness Exhibited in Electrospun Polystyrene Fibers

    Polystyrene (PS) is a potentially robust and high toughness plastic. PS commonly exhibits brittle behavior and poor mechanical properties due to the presence of structural heterogeneities promoting localized failure. Mechanical tensile testing of individual electrospun PS fibers demonstrates considerable enhancement of mechanical properties, including toughness increases of over two orders of magnitude compared to the bulk.

  3. Intelligent Nanofiber Composites: Dynamic Communication between Materials and Their Environment

    Intelligent matrix–fiber composites take advantage of hierarchical structures to interact with their environment. In nature, stimuli-responsive behavior is demonstrated by living systems like the human extracellular matrix, the Dynastes Hercules beetle, and Pinus seed pods. Utilizing these examples as inspiration, scientists are able to design a variety of composite platforms that act as release vehicles, sensors or switches, and actuators.

  4. Enhanced Optical Transmittance by Reduced Reflectance of Curved Polymer Surfaces

    W. Chen, Z. Diao, J.-H. Dirks, F. Geiger and J. Spatz

    A subwavelength nanostructure array is imprinted on a large thermoplastic material surface. Excellent antireflective properties over a wide range of wavelengths and angles of incidence are measured. The nanostructures can also be imprinted onto a flexible, curved surface. The fidelity of the nanostructured pattern is kept intact during the transfer and the resulting surfaces achieve high optical transmittance.

  5. PDMS Deposition for Optical Devices by Dip-Pen Nanolithography

    Moshe Zohar, Almog Refael Azulay, Dima Bykhovsky, Zeev Fradkin, Saad Tapuchi and Mark Auslender

    Version of Record online: 26 MAY 2017 | DOI: 10.1002/mame.201700053

    The performance of dip-pen nanolithography is studied. The dependence of the line width of the deposited polydimethylsiloxane ink on cantilever tip velocity, ambient relative humidity, and percentage of hexane diluting the ink is demonstrated. Extensive experimental results are displayed. The technology is discussed in the context of optical components fabrication.
