    A surficial bifunctional nanolayer is adopted on Nb2O5 microparticles by a simple nitridation process, where it results in higher ionic transport and further prevents the pulverizaton of Nb2O5. Upon decoration of Ag nanoparticles, electric conductivity of Nb2O5 is further improved, resulting in ultralong cycle retention at high current density (3000 mA g−1).

  2. Single Molecule Force Spectroscopy to Compare Natural versus Artificial Antibody–Antigen Interaction

    Using atomic force microscopy-based force spectroscopy, the binding affinity of an artificial antibody to an antigen (hemoglobin) is found to be weaker than that of a natural antibody. The fine difference in the molecular interactions manifests into a significant difference in the bioanalytical parameters of biosensors based on these recognition elements.

  3. Insulin-Responsive Glucagon Delivery for Prevention of Hypoglycemia

    An insulin-responsive glucagon delivery device based on a microneedle-array patch is developed for prevention of hypoglycemia. Utilizing hyperinsulinemia as a dangerous signal, this “smart glucagon patch” with a novel trigger mechanism can release glucagon to reduce the risk of hypoglycemia during diabetes management, which would profoundly improve the health as well as the quality of life of diabetic patients.

  4. A Phase-Separation Route to Synthesize Porous CNTs with Excellent Stability for Na+ Storage

    Zhi Chen, Taihong Wang, Ming Zhang and Guozhong Cao

    Version of Record online: 20 MAR 2017 | DOI: 10.1002/smll.201604045

    Porous carbon nanotubes (CNTs) are obtained by removing MoO2 nanoparticles from MoO2@C core@shell nanofibers which are synthesized by phase-segregation via a single-needle electrospinning method. As anodes for sodium-ion batteries, the porous CNT electrode displays excellent rate performance and cycling stability, which exhibites 110 mA h g−1 after 1200 cycles at 5 A g−1.

  5. Flexible Sensing Electronics for Wearable/Attachable Health Monitoring

    Xuewen Wang, Zheng Liu and Ting Zhang

    Version of Record online: 17 MAR 2017 | DOI: 10.1002/smll.201602790
