WebDownload scientific diagram High-angle annular dark field (HAADF)-scanning transmission electron microscopy (STEM) images showing the distribution of the catalyst on the C support. Next to it ... WebWe have analyzed the nanoscale organization of various polymer systems by utilizing high-angle annular dark field scanning transmission electron microscopy (HAADF−STEM). All systems under investigation are purely carbon based; in some cases staining was used for comparison with conventional transmission electron microscopy (CTEM) imaging.
