    New fiber-type piezoelectric nanogenerator devices consisting of radially aligned perovskite PbTiO3 nanotubes are designed for energy harvesting from arbitrary mechanical motion. The free-standing fiber-type nanogenerators generate constant amount of electric power by bending or wind motion regardless of direction, thus, extending the possibility of their practical applications.

  2. Atomic-Level-Designed Catalytically Active Palladium Atoms on Ultrathin Gold Nanowires

    Surgery at the atomic level: The Ag monolayer facilitates the deposition of isolated Pd atoms rather than continuous ones on ultrathin Au nanowires. During the hydrogenation of nitrophenol and the electrooxidation of ethanol, these two groups of Pd atoms show distinctive but geometry-dependent catalytic activity. This new atomic geometry maneuvering strategy is ready for the atomically precise design of nanocatalysts.

  3. Swarm Intelligence-Inspired Spontaneous Fabrication of Optimal Interconnect at the Micro/Nanoscale

    Meng Su, Zhandong Huang, Yong Huang, Shuoran Chen, Xin Qian, Wenbo Li, Yifan Li, Weihua Pei, Hongda Chen, Fengyu Li and Yanlin Song

    A spontaneous process is demonstrated to assemble nanoparticles into optimal interconnect, as natural systems spontaneously figuring out the shortest path. The optimal interconnect leads to a 65.9% decrease in electromagnetic interference, a 17.1% decrease in delay, and a 24.5% decrease in energy-delay. It will be of great significance for interconnect fabrication of versatile electronic circuits.

  4. Biomimicking of a Swim Bladder and Its Application as a Mini-Generator

    Mengmeng Song, Mengjiao Cheng, Meng Xiao, Lina Zhang, Guannan Ju and Feng Shi

    A model fish with man-made swim bladder achieves fast vertical motions based on density adjustments in a pressure-responsive way. When exposed to a magnetic field, a mini-generator is achieved by harvesting energy from the environment, working with pressure differences in the blood pressure range and at the frequency of a beating heart.

  5. Metal-Organic Framework as a Protective Coating for Biodiagnostic Chips

    Congzhou Wang, Sirimuvva Tadepalli, Jingyi Luan, Keng-Ku Liu, Jeremiah J. Morrissey, Evan D. Kharasch, Rajesh R. Naik and Srikanth Singamaneni

    A zeolitic imidazolate framework-8 (ZIF-8) grown around antibodies anchored to plasmonic nanostructures serve as a protective layer to preserve the biorecognition ability of antibodies stored at room and elevated temperatures for several days. The biofunctionality of the ZIF-8 protected biochip can be restored by a simple water rinsing step, making it highly convenient for use in point-of-care and resource-limited settings.
