      Colloidal InSb nanocrystals are synthesized by injecting stibine (SbH3) gas into a hot solution of indium myristate and dodecylamine in octadecene as described by Peter Reiss and co-workers on pages 828. Well-crystallized particles in the quantum confinement regime with a mean diameter of 8.8 nm and size dispersion below 15% are obtained. A synthetic pathway for the preparation of larger particles (∼100 nm) is also presented.

      The dendrimer molecules are spontaneously attached to the interface of liquid crystal microparticles dissolved in a glycerol matrix, forcing directors perpendicular to the interface. Photoisomerization reorients them from radial to tangential to the interface in the nematic, cholesteric and smectic A phases showing characteristic patterns as described by Hideo Takezoe and co-workers on pages 847.

    1. Synthesis of Colloidal Indium Antimonide Nanocrystals Using Stibine (pages 828–831)

      Axel Maurice, Miguel Lopez Haro, Bérangère Hyot and Peter Reiss

      Version of Record online: 10 JUN 2013 | DOI: 10.1002/ppsc.201300137

      A new approach for the chemical synthesis of colloidal indium antimonide (InSb) nanocrystals is reported. It relies on the in situ generation of stibine gas (SbH3) as the antimony precursor and yields highly crystalline particles with a mean diameter of 8.8 nm and low size dispersion (13%). A synthetic pathway for the preparation of larger particles (≈100 nm) is also presented.

    2. Preparation of SiO2-Encapsulated BaTiO3 Nanoparticles with Tunable Shell Thickness by Reverse Microemulsion (pages 832–836)

      Yanling Gao, Anna Elsukova and Doru C. Lupascu

      Version of Record online: 10 JUN 2013 | DOI: 10.1002/ppsc.201300104

      Thumbnail image of graphical abstract

      A silica coating on hydrophobic BaTiO3 nanoparticles is created using a reverse microemulsion route. The process is sufficiently controllable to target a tunable silica shell thickness by choosing appropriate BaTiO3 concentrations. Increasing the concentration of BaTiO3 nanoparticles is found to be an effective approach to decrease silica thickness.

    3. Monolayer of Nanorod Vertical Arrays Self-Assembled at the Air/Water Interface (pages 837–841)

      Wenbo Wei and Guanglu Ge

      Version of Record online: 20 JUN 2013 | DOI: 10.1002/ppsc.201300168

      Thumbnail image of graphical abstract

      A monolayer of gold nanorod vertical arrays is fabricated by interfacial self-assembly. It shows a high degree of ordering and strong coupling due to the small spacing between the nanorods. These continuous arrays cover an area of several millimeters and can be transferred to other substrates. They possess high uniformity in Raman enhancement over the entire sample.

    4. Dumbbell-Like Fe3O4–Au Nanoparticles for Ultrabroadband Electromagnetic Losses by Heterogeneous Interfacial Polarizations (pages 842–846)

      Xuefeng Zhang, Pengfei Guan and Junjie Guo

      Version of Record online: 27 JUN 2013 | DOI: 10.1002/ppsc.201300108

      Thumbnail image of graphical abstract

      Dumbbell-like Fe3O4–Au superparamagnetic nanoparticles exhibit enhanced electromagnetic losses at gigahertz ascribed to the epitaxial Fe3O4/Au interfaces that induce anisotropic polarizations. This provides insight into the microscopic dielectric polarization of heterogeneous hybrids of noble metal and magnetic oxide and thus has implication for potential applications, such as the development of high electromagnetic loss materials.

    1. Photoinduced Ordering Transition in Microdroplets of Liquid Crystals with Azo-Dendrimer (pages 847–852)

      Guksik Lee, Fumito Araoka, Ken Ishikawa, Yuichi Momoi, Osamu Haba, Koichiro Yonetake and Hideo Takezoe

      Version of Record online: 25 JUN 2013 | DOI: 10.1002/ppsc.201300110

      Thumbnail image of graphical abstract

      Photoinduced ordering transitions are successfully performed in azo-dendrimer-dissolved nematic, cholesteric, and smectic-A liquid crystal droplets dispersed in a glycerol matrix. Spontaneously attached photo-isomerizable dendrimer molecules at the droplet surfaces provide a possible way to control orientation in microdroplet systems, in which the interface cannot be treated by conventional surface agents.

    2. Magnetic Nanocomposites Formed by FeNi3 Nanoparticles Embedded in Graphene. Application as Supercapacitors (pages 853–863)

      Gonzalo Abellán, Eugenio Coronado, Carlos Martí-Gastaldo, Antonio Ribera and Toribio F. Otero

      Version of Record online: 21 JUN 2013 | DOI: 10.1002/ppsc.201300186

      Thumbnail image of graphical abstract

      A family of magnetic nanocomposites formed by FeNi3 ferromagnetic nanoparticles (NPs) embedded in a graphitized carbon matrix is reported. The coexistence of metal NPs and nanostructured carbon leads to a remarkable increase of their specific capacitance under high discharging current densities in comparison with the layered double hydroxide-based mixed oxide-carbon composite materials reported to date.

    3. Nitrogen-Doped Carbon with Mesopore Confinement Efficiently Enhances the Tolerance, Sensitivity, and Stability of a Pt Catalyst for the Oxygen Reduction Reaction (pages 864–872)

      Shuyan Gao, Hao Fan, Xianjun Wei, Liang Li, Yoshio Bando and Dmitri Golberg

      Version of Record online: 11 JUN 2013 | DOI: 10.1002/ppsc.201300121

      A potential electrocatalyst for the oxygen reduction reaction is synthesized. It exhibits high electrocatalytic activity, a four-electron oxygen reduction pathway, superior stability, fuel crossover resistance, and selective activity to a commercial Pt/C catalyst in alkaline solution. Such performance benefits from in situ covalent incorporation of Pt nanoparticles, excellent electrical contacts, and a favorable mesoporous structure.

    4. Formation of Sn@C Yolk–Shell Nanospheres and Core–Sheath Nanowires for Highly Reversible Lithium Storage (pages 873–880)

      Wei Ni, Yabo Wang and Rong Xu

      Version of Record online: 20 JUN 2013 | DOI: 10.1002/ppsc.201300138

      Thumbnail image of graphical abstract

      Tin/carbon core–shell conductive and breathable hollow nanostructures, namely, Sn@C yolk–shell nanospheres and core–sheath nanowires with sufficient buffering voids, are prepared by a controlled chemical vapor deposition (CVD) treatment of SnO2 hollow spheres with varied crystallinity. Both nanocomposites show effective suppression of the pulverization effect during the charging/discharging process and exhibit much stable cycling performance up to 500 cycles.

    5. Aerosol Synthesis and Reactivity of Thin Oxide Shell Aluminum Nanoparticles via Fluorocarboxylic Acid Functional Coating (pages 881–887)

      Daniel A. Kaplowitz, Guoqiang Jian, Karen Gaskell, Aldo Ponce, Panju Shang and Michael R. Zachariah

      Version of Record online: 7 AUG 2013 | DOI: 10.1002/ppsc.201300112

      An aerosol phase passivation coating of perfluoropentanoic acid on in situ generated bare nanoaluminum is accomplished, demonstrating a bridge bonding coordination between carboxylate and aluminum, a 1–2 nm coating layer, and enhanced active aluminum fuel content. The product exhibits a reduced ignition temperature in thermite combination with copper oxide.

    6. PdPt Nanocubes: A High-Performance Catalyst for Hydrolytic Dehydrogenation of Ammonia Borane (pages 888–892)

      Arlin Jose Amali, Kengo Aranishi, Takeyuki Uchida and Qiang Xu

      Version of Record online: 1 JUL 2013 | DOI: 10.1002/ppsc.201300100

      Thumbnail image of graphical abstract

      The bimetallic PdPt nanoparticles show significant dependency on the shape for catalytic hydrolysis of ammonia borane. The catalytic activity of PdPt cubic nanoparticles (cNPs) is found to be the best compared with spherical nanoparticles of Pd, Pt, and PdPt and cNPs of Pd. The turnover frequency (50.02 min−1) of PdPt cNPs is among the values of the most active catalysts.

    7. MFe2O4 and MFe@Oxide Core–Shell Nanoparticles Anchored on N-Doped Graphene Sheets for Synergistically Enhancing Lithium Storage Performance and Electrocatalytic Activity for Oxygen Reduction Reactions (pages 893–904)

      Junwu Xiao, Guiliang Xu, Shi-Gang Sun and Shihe Yang

      Version of Record online: 2 JUL 2013 | DOI: 10.1002/ppsc.201300105

      Thumbnail image of graphical abstract

      Introducing N-doped graphene sheets (NGS) into MFe2O4 enhances lithium storage performance by improving the electrical conductivity of the composites and preventing the self-aggregation. The subsequent reduction of the oxides to the metal@oxide core–shell structure increases the catalytic activity for oxygen reduction reaction by accelerating the electron transport from the catalytic active oxide layer to a highly conductive support NGS.

    8. Synthesis of a Au-on-Pd Heteronanostructure Stabilized by Citrate and its Catalytic Application (pages 905–910)

      Zhifei Wang, Shuang Zheng, Neng Wan, Liming Zhang, Qilong Wang, Nongyue He and Yaji Huang

      Version of Record online: 25 JUN 2013 | DOI: 10.1002/ppsc.201300152

      Thumbnail image of graphical abstract

      The formation of Au-on-Pd heteronanostructures depends greatly on the Pd/Au molar ratio when citrate-stabilized polycrystalline Pd nanoparticles are used as the seed. The catalytic performance, evaluated by the model reactions, demonstrates the advantage of using citrate as the stabilizer, in comparison with the strong ligand poly(vinyl pyrrolidone) (PVP)-stabilized PdAu nanoalloy.
