Synchrotron Science & Techniques

My first exposure to synchrotron science started with small & wide-angle X-ray scattering, SAXS & WAXS at Melbourne. I frequented @ausynchrotron. When I started PhD in NZ, I still visited Australian Synchrotron to do XPS

pubs.rsc.org/en/content/art… 2/ We focused on XPS because it can give qualitative insights into the relative size of Au clusters. Imaging these ultrasmall cluster using conventional HRTEM proved to be unsuccessful because the size is <1.5 nm. So, XPS is a good alternative because the BE shift ~ relative size
