    A seed-mediated synthesis of Au@Ag right bipyramids with high yield (>95%) and controllable edge length (from ≈130 to ≈230 nm) is reported. For the first time, a four-leaf-clover-like tetramer of bipyramids is obtained through self-assembly. The tetramer shows a great performance in surface-enhanced Raman spectroscopy with an analytical enhancement factor up to 1.4 × 107.

  2. Multifunctional Small Molecule Fluorophore for Long-Duration Tumor-Targeted Monitoring and Dual Modal Phototherapy

    Yi Ma, Min Zhang, Ping Li, Zhihao Han, Liming Wu, Tingting Li, Zhaohui Wang, Weidong Gao, Tao Deng and Yueqing Gu

    A small molecular fluorophore with inherent tumor-specific targeting ability for synchronous long-duration cancer imaging and enhanced dual modal phototherapy is promising for diverse use in cancer targeting, imaging, and therapy.

  3. Atomically Precise Transformations and Millimeter-Scale Patterning of Nanoscale Assemblies by Ambient Electrospray Deposition

    Anirban Som, Depanjan Sarkar, Sisira Kanhirathingal and Thalappil Pradeep

    Ambient electrospray deposition of metal ions is used to bring about chemical transformation of nanowire assemblies, directly in the solid state. By suitably controlling the exposure to these ambient metal-ion-beams, such a transformation can be restricted to the precision of one atomic layer, forming aligned arrays of axial as well as radial heterojunction nanowires.

  4. The 3D Nanoscale Evolution of Platinum–Niobium Oxide Fuel Cell Catalysts via Identical Location Electron Tomography

    David Rossouw, Lidia Chinchilla, Natalia Kremliakova and Gianluigi A. Botton

    Identical location tomography of a hybrid Pt catalyst on NbOx/Carbon support material: The 3D distribution of the Pt nanoparticles on the support, generated from a series of tilted images, is shown before (red) and after electrochemical cycling (green). Subsequently, data quantification shows the evolution of the material following electrochemical cycling, such as particle size evolution, coalescence, and detachment.

  5. Structural Insight into Stabilization of Pickering Emulsions with Fe3O4@SiO2 Nanoparticles for Enzyme Catalysis in Organic Media

    Yanning Qu, Renliang Huang, Wei Qi, Qi Qu, Rongxin Su and Zhimin He

    Various Pickering emulsions stabilized by Fe3O4@SiO2 nanoparticles (NPs) are produced for enzyme encapsulation. The catalytic performance is highly dependent on the hydrophobicity of NPs, which has great influence on the specific surface area of emulsion droplets and the interfacial mass transfer. The findings reveal a clear relation between NPs' structures and enzyme activity, facilitating the development of new emulsions for enzyme catalysis.
