    The age of neurons (either induced with chemokine CCL11 or cultured for up to 3 weeks) affects the endocytic uptake of chitosan-coated magnetic nanoparticles, with impairment of clathrin-mediated endocytosis increasing with age. The neuro-protective effects of chitosan coatings on magnetic nanoparticles are also age-dependent due to reduced intracellular trafficking of magnetic nanoparticles with age.

  2. Study of the Mechanical Behavior of Radially Grown Fivefold Twinned Nanowires on the Atomic Scale

    In situ bending tests and dynamic modeling simulations are for the first time revealing the mechanical behavior of copper nanowires (NW) with radially grown fivefold twin structures on the atomic scale. Combining the simulations with the experimental results it is shown that both the twin boundaries (TBs) and the twin center act as dislocation sources. TB migration and L-locks are readily observed in these types of radially grown fivefold-twin structures.

  3. Black Phosphorus Nanosheets: Synthesis, Characterization and Applications

    Black phosphorus (BP) exhibits extraordinary performance, both in electronics and wide range optoelectronic devices due to its suitable bandgap. The unconventional anisotropy in BP arises from its puckered structure, which makes it an anisotropic material at large magnitude. It also has potential applications in gas sensing at ultralow level detection towards various gases, energy storage devices and thermoelectric applications.

  4. Graphene-Analogues Boron Nitride Nanosheets Confining Ionic Liquids: A High-Performance Quasi-Liquid Solid Electrolyte

    Mingtao Li, Wenshuai Zhu, Pengfei Zhang, Yanhong Chao, Qian He, Bolun Yang, Huaming Li, Albinab Borisevich and Sheng Dai

    Version of Record online: 25 MAY 2016 | DOI: 10.1002/smll.201600358

    A quasi-liquid solid electrolyte with novel graphene-analogues boron nitride nanosheets confining an ultrahigh concentration of ionic liquids in an interlayer and out-of-layer chamber is presented and possesses a solid state yet with liquid electrolyte merits.

  5. Self-Sensitized Carbon Nitride Microspheres for Long-Lasting Visible-Light-Driven Hydrogen Generation

    Self-sensitized carbon nitride microspheres, possessing a microsphere core of oxygen-containing carbon nitride and self-sensitized surfaces by covalently linked 1,3,5-triazine based oligomer, exhibit high visible-light activities for H2 generation with excellent stability. This new type of highly stable self-sensitized metal-free semiconductor opens a new direction of future development of low-cost photocatalysts for efficient and stable solar fuels production.
