Pt-Decorated PdCo@Pd/C Core-Shell Nanoparticles with Enhanced Stability and Electrocatalytic Activity for Oxygen Reduction Reaction
Deli Wang, Huolin L. Xin, Yingchao Yu +4
A simple method for the preparation of PdCo@Pd core-shell nanoparticles supported on carbon has been developed using an adsorbate-induced surface segregation effect. The stability…
Extended Depth of Field for High Resolution Scanning Transmission Electron Microscopy
Robert Hovden, Huolin L. Xin, David A. Muller
Aberration-corrected scanning transmission electron microscopes (STEM) provide sub-angstrom lateral resolution; however, the large convergence angle greatly reduces the depth of fi…
Imaging Grains and Grain Boundaries in Single-Layer Graphene: An Atomic Patchwork Quilt
Pinshane Y. Huang, Carlos S. Ruiz-Vargas, Arend M. van der Zande +8
The properties of polycrystalline materials are often dominated by the size of their grains and by the atomic structure of their grain boundaries. These effects should be especiall…
