  1. Ultralight, Soft Polymer Sponges by Self-Assembly of Short Electrospun Fibers in Colloidal Dispersions

    Ultralight 3D electrospun polymer sponges with densities below 3 mg cm−3 are obtained by freeze-drying of dispersions of short electrospun fibers. This sponge is soft but reversibly compressible, which accounts to a hierarchical pore structure. It is hydrophobic and shows extremely high hydrophobic liquid absorption ability because of pore filling rather than surface wetting. These polymer sponges are of interest for cell culturing.

  2. In Situ Production of Biofunctionalized Few-Layer Defect-Free Microsheets of Graphene

    Biofunctionalized defect-free few-layer graphene microsheets can be obtained using liquid phase ultrasonic exfoliation of raw graphitic material assisted by the self-assembling fungal hydrophobin Vmh2. This approach enables a highly concentrated and stable exfoliated product. The obtained material is likely to prove valuable for the emerging applications of graphene in the biotechnological field.

  3. Biocompatible Nanoparticles Based on Diketo-Pyrrolo-Pyrrole (DPP) with Aggregation-Induced Red/NIR Emission for In Vivo Two-Photon Fluorescence Imaging

    Yuting Gao, Guangxue Feng, Tao Jiang, Chiching Goh, Laiguan Ng, Bin Liu, Bo Li, Lin Yang, Jianli Hua and He Tian

    Article first published online: 30 MAR 2015 | DOI: 10.1002/adfm.201500010

    Design and synthesis of two novel red/NIR emissive DPP-based compounds with large two-photon absorption cross-sections and aggregation-induced emission properties are reported. After being fabricated by DSPE-PEG-Mal and CPP, DPP-2-CPP nanoparticles are used for cell imaging and two-photon imaging, with clear visualization of blood vasculature inside mouse ear skin.

  4. MoS2/Si Heterojunction with Vertically Standing Layered Structure for Ultrafast, High-Detectivity, Self-Driven Visible–Near Infrared Photodetectors

    Liu Wang, Jiansheng Jie, Zhibin Shao, Qing Zhang, Xiaohong Zhang, Yuming Wang, Zheng Sun and Shuit-Tong Lee

    Article first published online: 30 MAR 2015 | DOI: 10.1002/adfm.201500216

    A new type of visible–near infrared self-driven photodetector is developed by sputtering a layer of n-type MoS2 film with a vertically standing layered structure on p-type silicon. With the advantages of easy fabrication, wide response spectrum, extremely high detectivity (≈1013 Jones), ultrafast response speed (≈3 μs), and good durability, this heterojunction photodetector shows great potential for optoelectronic applications.

  5. Symmetric and Asymmetric Decoration of Graphene: Bimetal-Graphene Sandwiches

    Peter S. Toth, Matěj Velický, Quentin M. Ramasse, Desponia M. Kepaptsoglou and Robert A. W. Dryfe

    Article first published online: 30 MAR 2015 | DOI: 10.1002/adfm.201500277

    Graphene is asymmetrically functionalized with different metal nanoparticles. Such dual-decorated graphene-based metal nanoclusters are studied using various microscopic techniques and several spectroscopic methods to prove the double-side decorated monolayer graphene. The preparation of sandwich structures of graphene with two different species opens the way for further asymmetric decoration processes at the polarizable liquid/liquid interface.
