How does one learn more about the characteristics of the Martian atmospheric chemistry and climate system while seated 56 million plus kilometres away? Using MAX IV’s HIPPIE beamline, an international research group studied the surface solvation of salts from Earth’s Qaidam Basin, which bear close resemblance to Martian salts and how these influence the respective planet’s surface. The work also establishes the feasibility of the APXPS technique for future studies with Martian salts.
One of the key challenges in catalysis research is to understand how catalysts’ structure and function relate to each other. Regardless of the type of catalyst in question, structure and function are dynamic with a strong dependence on the localized reaction conditions such as temperature, pressure, and gas composition just above the catalyst surface. Now, researchers developed a new event-averaging-based method employing time-resolved ambient pressure photoelectron spectroscopy to map catalyst structure and local gas environment simultaneously while reaction conditions change rapidly.
In a new publication in Nature Communications, a team from the Dutch company Syngaschem BV and the Dutch Institute for Fundamental Energy Research elucidates for the first time some aspects of the Fischer-Tropsch reaction, used for converting synthesis gas into synthetic fuels. Analysis performed at the HIPPIE beamline at MAX IV was instrumental to achieving these results.
