  1. Dendrite-Free Nanostructured Anode: Entrapment of Lithium in a 3D Fibrous Matrix for Ultra-Stable Lithium–Sulfur Batteries

    Xin-Bing Cheng, Hong-Jie Peng, Jia-Qi Huang, Fei Wei and Qiang Zhang

    Entrapment of free lithium in a 3D fibrous Li7B6 framework allows LiB nanostructured anodes with stable interfaces between the electrolyte and the electrode, which retards the formation of lithium dendrites. A lithium–sulfur cell with a nanostructured anode is created with a high Coulombic efficiency and high capacity retention rate of 36.3% after 2000 cycles.

  2. A Radial Flow Microfluidic Device for Ultra-High-Throughput Affinity-Based Isolation of Circulating Tumor Cells

    The isolation of circulating tumor cells (CTCs) is addressed by emerging microfluidic technologies employing different isolation techniques. Here, a radial flow microfluidic device, the OncoBean Chip, is presented. The device performs affinity-based capture of CTCs with high-throughput.

  3. Strong Thermo-Induced Single And Two-Photon Green Luminescence In Self-Organized Peptide Microtubes

    S. Semin, A. van Etteger, L. Cattaneo, N. Amdursky, L. Kulyuk, S. Lavrov, A. Sigov, E. Mishina, G. Rosenman and Th. Rasing

    Article first published online: 29 JUL 2014 | DOI: 10.1002/smll.201401602

    Diphenylalanine peptide nano- and microtubes formed by self-assembly demonstrate strongly enhanced and tunable single-photon and two-photon luminescence in the visible range, which appears after heat- or laser treatment of these self-organized peptide microtubes. This process significantly extends the functionality of these microstructures and can trigger a new interest in the optical properties of structures based on short peptides.

  4. Conjugated Polymer/Nanocrystal Nanocomposites for Renewable Energy Applications in Photovoltaics and Photocatalysis

    Yu-Wei Su, Wei-Hao Lin, Yung-Jung Hsu and Kung-Hwa Wei

    Article first published online: 29 JUL 2014 | DOI: 10.1002/smll.201401508

    Nanocomposites comprising nanocrystals and conjugated polymers that have relative offset energy band structure can not only complement the light absorption range but also result in a dissociation of charge transfer excitons— electrons transfer to the nanocrystals and holes remain in the conjugated polymers—that generates photocurrent for photovoltaic applications or reducing/oxidizing reactions on species for photocatalysis applications.

  5. Learning from Nature: Binary Cooperative Complementary Nanomaterials

    Bin Su, Wei Guo and Lei Jiang

    Article first published online: 29 JUL 2014 | DOI: 10.1002/smll.201401307

    Nature-inspired binary cooperative complementary nanomaterials (BCCNMs) mean unique materials consist of two components with entirely opposite properties. BCCNMs can exhibit new/unique properties, even switch reversibly between two entirely opposite statuses. The concept of binary cooperative complementary widely exists in nanomaterial design and might open a new avenue for generating next-generation metamaterials.
