- Self-Supporting AuCu@Cu Elongated Pentagonal Bipyramids Toward Neutral Glucose Sensing
Gang Wang, Zhitong Jin, Meirong Zhang and Zhong-Sheng Wang
Version of Record online: 20 JUN 2016 | DOI: 10.1002/ppsc.201600077
Penta-twinned Cu elongated pentagonal bipyramids are synthesized as supports, and HAuCl4 is reduced in situ to form an AuCu alloy on the surface of Cu, generating a self-supporting AuCu@Cu core–shell structure. The AuCu@Cu elongated pentagonal bipyramids with 0.42 at% Au act as poison-resistant and durable catalyst for glucose sensing in a neutral solution.
- Synthesis of Porous NiO Nanorods as High-Performance Anode Materials for Lithium-Ion Batteries
Qian Li, Gang Huang, Dongming Yin, Yaoming Wu and Limin Wang
Version of Record online: 20 JUN 2016 | DOI: 10.1002/ppsc.201600084
Porous NiO nanorods are synthesized by solvothermal method followed by a thermal treatment process in air. The as-synthesized porous NiO nanorods copy well the morphology of Ni-MIL-77 and the porous character is ascribed to the liberation the gas molecules. When used as anode materials for lithium-ion batteries, the NiO electrode exhibits excellent electrochemical performance.
- Amphiphilic Core–Shell Nanocomposite Particles for Enhanced Magnetic Resonance Imaging
Lianghui Chen, Dechao Niu, Cheng Hao Lee, Yuan Yao, Ki Lui, Kin Man Ho and Pei Li
Version of Record online: 20 JUN 2016 | DOI: 10.1002/ppsc.201600095
A new class of iron-oxide-based magnetic resonance agent with high biocompatibility and enhanced transverse relaxivity is developed. It is based on amphiphilic core–shell nanocomposite particles consisting of biocompatible chitosan shells and poly(methyl methacrylate) cores confining multiple aggregated γ-Fe2O3 nanoparticles.
- Quantifying a Heterogeneous Ru Catalyst on Carbon Black Using ADF STEM
Aakash M. Varambhia, Lewys Jones, Annick De Backer, Vidar T Fauske, Sandra Van Aert, Dogan Ozkaya and Peter D. Nellist
Version of Record online: 17 JUN 2016 | DOI: 10.1002/ppsc.201600067
Using annular dark field scanning transmission electron microscopy (ADF STEM), a Ru-on-carbon-black catalyst is imaged and the images are quantified. These results reveal that Ru initially appears as a thin amorphous layer that, during prolonged electron beam exposure, can form stable face-centered cubic crystalline rafts up to 5–6 atoms thick.
