    Synergetic advantages of superior electrical conductivity and excellent reaction activity from inorganic lattices render 2D nanomaterials ideal candidates for electrode active materials in electrochemical applications towards energy conversion and storage. In this concept article, recent progress on regulating the electrical behaviors of two-dimensional inorganic nanomaterials for energy applications are discussed.

  2. Single-Mode Lasing from Colloidal Water-Soluble CdSe/CdS Quantum Dot-in-Rods

    In optoelectronic device fabrication, water solubility of nanocrystal materials is advantageous for simple and environmentally friendly processing routes. Towards LEDs, highly luminescent core–shell quantum dot-in-rods (QDRs) demonstrate excellent performance as emitters. Increasing in shell thickness allows the transfer of CdSe/CdS QDRs into aqueous solution without reducing their emission, and drop deposition leads to single mode microlasers with low threshold.

  3. Tailoring the Height of Ultrathin PbS Nanosheets and Their Application as Field-Effect Transistors

    Thomas Bielewicz, Sedat Dogan and Christian Klinke

    Article first published online: 21 OCT 2014 | DOI: 10.1002/smll.201402144

    Controlled synthesis of large, two-dimensional PbS nanosheets with tunable height is presented. Through a variation in ligand concentration it is possible to tailor the height of the PbS nanosheets, which show different optical and electronic characteristics as a function of their height.

  4. Rapid Quantification of Live Cell Receptors Using Bioluminescence in a Flow-Based Microfluidic Device

    Ramesh Ramji, Cheong Fook Chiong, Hiroaki Hirata, Abdur Rub Abdur Rahman and Chwee Teck Lim

    Article first published online: 21 OCT 2014 | DOI: 10.1002/smll.201401674

    A new method of quantifying live cell surface receptor numbers by integrating bioluminescence with microfluidics and lens-free optics is presented. This significantly improves upon other methods by providing miniaturized detection modules with higher sensitivity, specificity, lower consumption of analytes, reduced assay times, and by allowing multiplex functions for high-throughput cell screening assays.

  5. Kinetically Controlled Synthesis of PdNi Bimetallic Porous Nanostructures with Enhanced Electrocatalytic Activity

    Chengzhou Zhu, Dan Wen, Martin Oschatz, Matthias Holzschuh, Wei Liu, Anne-Kristin Herrmann, Frank Simon, Stefan Kaskel and Alexander Eychmüller

    Article first published online: 21 OCT 2014 | DOI: 10.1002/smll.201401432

    A class of 3D PdNi bimetallic nano­materials with porous nanostructures is synthesized using a facile and versatile approach at room temperature. Due to their porous nanostructures, their clean surfaces, as well as the synergistic effect between their compositions, the as-prepared PdNi exhibit greatly enhanced activity and stability towards methanol electrooxidation in an alkaline medium, holding great promise in fuel cells.
