  1. Tailoring Functional Interlayers in Organic Field-Effect Transistor Biosensors

    Maria Magliulo, Kyriaki Manoli, Eleonora Macchia, Gerardo Palazzo and Luisa Torsi

    Article first published online: 27 NOV 2014 | DOI: 10.1002/adma.201403477

    Biomaterials are successfully integrated in OTFT devices as biorecognition elements to develop ultrasensitive label-free electronic biosensors or as gating materials to obtain highly performing devices.

  2. Active Micro-Actuators for Optical Modulation Based on a Planar Sliding Triboelectric Nanogenerator

    Chi Zhang, Wei Tang, Yaokun Pang, Changbao Han and Zhong Lin Wang

    Article first published online: 27 NOV 2014 | DOI: 10.1002/adma.201404291

    Based on a triboelectric nanogenerator (TENG) the first active micro-actuator for optical modulation driven by mechanical energy without external power or mechanical joint is presented. This demonstrates the enormous potential of TENGs for independent and sustainable self-powered micro/nano electromechanical systems, and opens up new ­applications of TENGs in triboelectric-voltage-controlled devices.

  3. Superelastic Supercapacitors with High Performances during Stretching

    Article first published online: 25 NOV 2014 | DOI: 10.1002/adma.201404573

    A fiber-shaped supercapacitor that can be stretched over 400% is developed by using two aligned carbon nanotube/polyaniline composite sheets as electrodes. A high specific capacitance of approximately 79.4 F g−1 is well maintained after stretching at a strain of 300% for 5000 cycles or 100.8 F g−1 after bending for 5000 cycles at a current density of 1 A g−1. In particular, the high specific capacitance is maintained by 95.8% at a stretching speed as high as 30 mm s−1.

  4. Large-Pore Ultrasmall Mesoporous Organosilica Nanoparticles: Micelle/Precursor Co-templating Assembly and Nuclear-Targeted Gene Delivery

    Meiying Wu, Qingshuo Meng, Yu Chen, Yanyan Du, Lingxia Zhang, Yaping Li, Linlin Zhang and Jianlin Shi

    Article first published online: 25 NOV 2014 | DOI: 10.1002/adma.201404256

    A novel micelle/precursor co-templating assembly strategy is successfully developed to synthesize large-pore ultrasmall mesoporous organosilica nanoparticles (MONs). Furthermore, elaborately designed MONs with a cell-penetrating peptide (TAT) (MONs–PTAT) are constructed for highly efficient intranuclear gene delivery. They exhibit a high loading capacity, improved protection for the loaded gene, and enhanced transfection efficiencies of EGFP plasmid (pEGFP).

  5. Multicolored Organic/Inorganic Hybrid Perovskite Light-Emitting Diodes

    Young-Hoon Kim, Himchan Cho, Jin Hyuck Heo, Tae-Sik Kim, NoSoung Myoung, Chang-Lyoul Lee, Sang Hyuk Im and Tae-Woo Lee

    Article first published online: 25 NOV 2014 | DOI: 10.1002/adma.201403751

    Bright organic/inorganic hybrid perov­skite light-emitting diodes (PrLEDs) are realized by using CH3NH3PbBr3 as an emitting layer and self-organized buffer hole-injection layer (Buf-HIL). The PrLEDs show high luminance, current efficiency, and EQE of 417 cd m−2, 0.577 cd A−1, and 0.125%, respectively. Buf-HIL can facilitate hole injection into CH3NH3PbBr3 as well as block exciton quenching.
