  1. Mesoporous Colloidal Superparticles of Platinum-Group Nanocrystals with Surfactant-Free Surfaces and Enhanced Heterogeneous Catalysis

    Yongxing Hu, Yuzi Liu and Yugang Sun

    Article first published online: 23 JAN 2015 | DOI: 10.1002/adfm.201403664

    Colloidal superparticles consisting of platinum nanocrystals embedded in silver chloride matrix are synthesized through a self-limited coprecipitation on sacrificial substrates of colloidal silver particles. ­Selective dissolution of silver chloride leads to the formation of porous superparticles of platinum with ligand-free surfaces that are beneficial for solution-phase heterogeneous catalysis.

  2. Self-Limited Switching in Ta2O5/TaOx Memristors Exhibiting Uniform Multilevel Changes in Resistance

    Article first published online: 23 JAN 2015 | DOI: 10.1002/adfm.201403621

    A self-limited switching circuit for uniformly regulating the resistance states is first suggested. This circuit, which is composed of memristor, switch, and resistor, is successfully established in a Ta2O5/TaOx structure. In this device, low- and high-resistance states, and their intermediate resistance states are precisely regulated, and thus, multilevel switching is successfully achieved.

  3. Ultrafast All-Polymer Electrically Tunable Silicone Lenses

    Luc Maffli, Samuel Rosset, Michele Ghilardi, Federico Carpi and Herbert Shea

    Article first published online: 23 JAN 2015 | DOI: 10.1002/adfm.201403942

    Soft and electrically tunable lenses based on dielectric elastomer actuators are fabricated and exhibit settling time below 175 μs. Soft and compliant systems can also display fast response speed by a proper choice of materials and an adequate design. The lens, based on a low-loss commercial silicone, is able to modulate its focal length by 20%.

  4. Transparent, Stimuli-Responsive Films from Cellulose-Based Organogel Nanoparticles

    Yonggui Wang, Lars-Oliver Heim, Yeping Xu, Gerd Buntkowsky and Kai Zhang

    Article first published online: 22 JAN 2015 | DOI: 10.1002/adfm.201403067

    Novel cellulose-based organogel nanoparticles, called surface-stearoylated cellulose nanoparticles (SS-CNPs), are synthesized after the surface esterification of cellulose fibers under heterogeneous reaction conditions. SS-CNPs form stimuli-responsive organogels and transparent, self-standing films by solvent casting. The films show solvent-responsive surface wettability, responsive shape-memory properties as well as switchable optical colors by forming nanocomposite films containing stearoylated rhodamine spiroamide.

  5. MoS2/Graphene Composite Anodes with Enhanced Performance for Sodium-Ion Batteries: The Role of the Two-Dimensional Heterointerface

    Xiuqiang Xie, Zhimin Ao, Dawei Su, Jinqiang Zhang and Guoxiu Wang

    Article first published online: 22 JAN 2015 | DOI: 10.1002/adfm.201404078

    MoS2/reduced graphene oxide nano­composites are prepared as anode materials for sodium-ion batteries. The performance of MoS2/reduced graphene oxide nano­composites is closely related to the heterointerfacial areas. Computational investigations reveal that the 2D MoS2/reduced graphene oxide heterointerface can increase the conductivity of MoS2, adsorb more Na atoms, and maintain high diffusion mobility of Na on MoS2 surface and electron transfer efficiency from Na to MoS2.
