  1. Direct Hydrothermal Synthesis of Carbonaceous Silver Nanocables for Electrocatalytic Applications

    Chuyang Chen, Bryan Harry Rahmat Suryanto, Chuan Zhao, Xuchuan Jiang and Aibing Yu

    Article first published online: 25 MAR 2015 | DOI: 10.1002/smll.201401854

    The direct hydrothermal synthesis of both carbonaceous silver nanocables and carbonaceous nanotubes with template-free and simple synthesis procedures are demonstrated under mild conditions. The carbonaceous nanostructures, with controllable sizes and porous walls, show potential applications in electrochemical catalysis in oxygen reduction reaction, but at a much lower cost than the commonly used platinum.

  2. Well-Dispersed and Size-Controlled Supported Metal Oxide Nanoparticles Derived from MOF Composites and Further Application in Catalysis

    Hong Liu, Suoying Zhang, Yayuan Liu, Zhuhong Yang, Xin Feng, Xiaohua Lu and Fengwei Huo

    Article first published online: 25 MAR 2015 | DOI: 10.1002/smll.201401791

    Supported metal oxide nanoparticles are important in heterogeneous catalysis, however, the ability to tailor their size, structure, and dispersion remains a challenge. A strategy to achieve well-dispersed and size-controlled supported metal oxides through the manageable growth of a metal organic framework (Cu–BTC) on TiO2 is described here, followed by pyrolysis.

  3. High-Performance Sb/Sb2O3 Anode Materials Using a Polypyrrole Nanowire Network for Na-Ion Batteries

    Do-Hwan Nam, Kyung-Sik Hong, Sung-Jin Lim, Min-Joong Kim and Hyuk-Sang Kwon

    Article first published online: 25 MAR 2015 | DOI: 10.1002/smll.201500491

    A 3D porous Sb/Sb2O3–PPy electrode exhibits excellent cycle performance and outstanding rate capabilities due to not only high porosity of the polypyrrole nanowire network but also the buffer effects of the Sb2O3 matrix on the volume expansion of Sb.

  4. Hybrid Films of Graphene and Carbon Nanotubes for High Performance Chemical and Temperature Sensing Applications

    Tran Thanh Tung, Cuong Pham-Huu, Izabela Janowska, TaeYoung Kim, Mickael Castro and Jean-Francois Feller

    Article first published online: 25 MAR 2015 | DOI: 10.1002/smll.201403693

    The hybrid film of 1D carbon nanotubes and 2D graphene is prepared using poly(ionic liquid) as interlinker for use as dual detection of chemical and temperature sensing. Their responses to trace amount of volatile organic compounds or small temperature gradient with fast response, high sensitivity, and stability, may offer a new platform for the chemo-resistive or thermoelectric temperature sensors.

  5. Ultrafast Graphene Growth on Insulators via Metal-Catalyzed Crystallization by a Laser Irradiation Process: From Laser Selection, Thickness Control to Direct Patterned Graphene Utilizing Controlled Layer Segregation Process

    Henry Medina, Chih-Chi Huang, Hung-Chiao Lin, Yu-Hsian Huang, Yu-Ze Chen, Wen-Chun Yen and Yu-Lun Chueh

    Article first published online: 24 MAR 2015 | DOI: 10.1002/smll.201403463

    Few-layer graphene is directly synthesized on insulating substrates by laser irradiation. The segregation of graphene layers is manipulated by tuning the metal layer thickness. Submicrometer patterning resolution can be achieved by an intermediate metal layer pattern using lithography methods.
