  1. Mechanical Force-Driven Growth of Elongated Bending TiO2-based Nanotubular Materials for Ultrafast Rechargeable Lithium Ion Batteries

    A stirring hydrothermal process that enables the formation of elongated bending TiO2–based nanotubes is presented. By making use of its bending nature, the elongated TiO2(B) nanotubular cross-linked network anode electrode can cycle over 10000 times in half cells while retaining a relatively high capacity (114 mAh g−1) at ultra-high rate of 25 C (8.4 A/g).

  2. A Light-Powered Bio-Capacitor with Nanochannel Modulation

    Article first published online: 10 JUL 2014 | DOI: 10.1002/adma.201401321

    An artificial bio-capacitor system is established, consisting of the proton-pump protein proteorhodopsin and a modified alumina nanochannel, inspired by the capacitor-like behavior of plasma membranes realized through the cooperation of ion-pump and ion-channel proteins. Capacitor-like features of this simplified system are realized and identified, and the photocurrent duration time can be modulated by nanochannel modification to obtain favorable square-wave currents.

  3. Controlled Growth of Single-Crystal Twelve-Pointed Graphene Grains on Liquid Cu Surface

    Dechao Geng, Lan Meng, Bingyan Chen, Enlai Gao, Wei Yan, Hui Yan, Birong Luo, Jie Xu, Huaping Wang, Zupan Mao, Zhiping Xu, Lin He, Zhiyong Zhang, Lianmao Peng and Gui Yu

    Article first published online: 10 JUL 2014 | DOI: 10.1002/adma.201401277

    The controlled fabrication of single-crystal twelve-pointed graphene grains is demonstrated for the first time by ambient pressure chemical vapor deposition on a liquid Cu surface. An edge-diffusion limited mechanism is proposed. The highly controllable growth of twelve-pointed graphene grains presents an intriguing case for the fundamental study of graphene growth and should exhibit wide applications in graphene-based electronics.

  4. Recent Advances in Transition Metal Complexes and Light-Management Engineering in Organic Optoelectronic Devices

    Wallace C. H. Choy, Wai Kin Chan and Yuping Yuan

    Article first published online: 10 JUL 2014 | DOI: 10.1002/adma.201306133

    The recent development of phosphorescent transition metal complexes for the fabrication of highly efficient and multicolored organic light-emitting devices and the use of novel light-management techniques to enhance the efficiency of light-emitting and solar-light-harvesting devices are discussed.

  5. Highly Sensitive Gas Sensor by the LaAlO3/SrTiO3 Heterostructure with Pd Nanoparticle Surface Modulation

    Ngai Yui Chan, Meng Zhao, JianXing Huang, Kit Au, Man Hon Wong, Hei Man Yao, Wei Lu, Yan Chen, Chung Wo Ong, Helen Lai Wa Chan and Jiyan Dai

    Article first published online: 10 JUL 2014 | DOI: 10.1002/adma.201401597

    The palladium nanoparticle (Pd NP) decorated LaAlO3/SrTiO3 (LAO/STO) heterostructure is for the first time used as a hydrogen gas sensor with very high sensitivity and workability at room-temperature. The outstanding gas sensing properties are due to the Pd NPs’ catalytic effect to different gases, resulting in charge coupling between the gas mole­cules and the 2DEG through Pd NPs by either a direct charge exchange or change of electron affinity. These results provide insight into the emerging properties at LAO/STO interfaces.
