چکیده
Real-time electron microscopy observations of processes in wet environments, i.e., solutions, liquids, etc. have become possible only very recently with the development of electron beam transparent cells, in which a liquid layer is trapped between two ultrathin, electron-transparent membranes. Liquid-cell transmission electron microscopy (TEM) and scanning TEM (STEM) have attracted a lot of interest as they give direct insight into processes such as solution synthesis of nanostructures [1, 2], electrochemistry [3], biological phenomena, etc.

Ni@Pt core-shell nanoparticles as an improved electrocatalyst for ethanol electrooxidation in alkaline media
Core-shell nanostructures are emerging as more important materials than alloy nanostructures and have much more interesting potential applications in various fields. In this work, we demonstrated the fast and facile synthesis of core-shell nanoparticles consisting of Pt thin layer as the shell and Ni nanoparticles as the cores. The described method herein is suitable for large-scale and low-cos...

متن کاملIn-situ Liquid Phase Epitaxy: Another Strategy to Synthesize Heterostructured Core-shell Composites.
Core-shell Nb2O5/TiO2 composite with hierarchical heterostructure is successfully synthesized In-situ by a facile template-free and acid-free solvothermal method based on the mechanism of liquid phase epitaxy. The chemical circumstance change induced by the alcoholysis of NbCl5 is utilized tactically to trigger core-shell assembling In-situ. The tentative mechanism for the self-assembling of co...
