    Fermi level control over the whole electronic gap of an organic semiconductor is demonstrated by applying the concept of molecular p- and n-type doping. In particular, observation of the dopant saturation and reserve regimes is shown for the first time in organic semiconductors, substantiating the cross-link to classical semiconductor theory. At ultralow concentrations doping provides filling of trap states.

    Improved spermbot performance is demonstrated by biofunctionalization of the inner tube surface, shorter tube design, and caffeine addition. Firstly, spermbot velocity is improved by the use of shorter microtubes; secondly, better coupling efficiency is achieved by binding of fibronectin inside the microtube; and finally, caffeine addition gives a temporary speed boost to the spermbot.

  3. Efficiently Releasing the Trapped Energy Flow in White Organic Light-Emitting Diodes with Multifunctional Nanofunnel Arrays

    A powerful method for drastically releasing the trapped energy flow in white organic light-emitting diodes is demonstrated by nanoimprinting multifunctional quasi-periodic nanofunnel arrays. The broadband light extraction is realized without spectral changes and angular dependence, yielding an external quantum efficiency 2.3 times that of the conventional device and improved power efficiency. This extraction nanostructure also affords the enticing capacity against scrubbing and the self-cleaning feature.

  4. Sunlight-Induced Cross-Linked Luminescent Films Based on Polysiloxanes and d-Limonene via Thiol–ene “Click” Chemistry

    Yujing Zuo, Jinfeng Cao and Shengyu Feng

    Article first published online: 26 MAR 2015 | DOI: 10.1002/adfm.201500187

    The first example of sunlight-induced cross-linked luminescent films based on polysiloxanes and d-limonene shows potential applications in fabricating colorful UV-light emitting diodes. This study demonstrates how an appropriate synthesis strategy can be applied to terpene monomers while allowing the development of new environmentally benign materials.

  5. Reduced Graphene Oxide-Modified Carbon Nanotube/Polyimide Film Supported MoS2 Nanoparticles for Electrocatalytic Hydrogen Evolution

    Yimin Jiang, Xin Li, Shengjiao Yu, Lingpu Jia, Xiaojuan Zhao and Chunming Wang

    Article first published online: 25 MAR 2015 | DOI: 10.1002/adfm.201500194

    A reduced graphene oxide-modified carbon nanotube/polyimide-MoS2 film with a small loading of MoS2 exhibits a low overpotential and achieves large current densities at low overpotentials with the synergic effect of MoS2 and reduced graphene oxide-modified carbon nanotube/polyimide film. The excellent hydrogen evolution reaction electrocatalytic activity and good stability suggest the potential application of reduced graphene oxide-modified carbon nanotube/poly­imide-MoS2 film in energy conversion.
