Research in a wide range of disciplines – materials science, nano-science, heterogeneous catalysis, corrosion science, polymer science to name but a few – is in strong need of improved surface imaging techniques with structural, chemical, electronic, and magnetic contrasts at spatial resolutions in the nanometer range. Spectroscopic PhotoElectron and Low Energy Electron Microscope (SPELEEM) is unique in that it provides easy access to all of these contrast mechanisms at resolutions in the nanometer range in a single instrument. One of recent and the most important developments concerning this instrument is the upgrade to a microscope with an aberration corrector, which improves the spatial resolution of the microscope by an order of magnitude while increasing the transmission by a similar factor. SPELEEM also has the advantage of having a large dynamic range of view of up to ~100 micrometres thereby facilitating easy access to the structure of not only the nanometer but the micrometer scale as well. Finally, as the detection in SPELEEM is done at video-rates, monitoring of real-time dynamical processes is possible.

MAXPEEM monitors inclusions to control the properties of ultra-high-strength steel

A research team from Finland, Netherlands and Sweden has used the MAXPEEM beamline to study non-metallic inclusions in ultra-high-strength steel. Such additions to the steel matrix may have significant effects on the steel properties and are therefore important to know and control. Ultra-high-strength steels are crucial engineering materials used in various fields ranging from the
