TL;DR: Two new soft X-ray scanning transmission microscopes located at the Advanced Light Source (ALS) have been designed, built and commissioned and interferometer control implemented in both microscopes allows the precise measurement of the transverse position of the zone plate relative to the sample.

TL;DR: In this paper, the influence of oxidative restructuring on the selectivity for acetylene hydrogenation to ethylene was studied under conditions of industrial significance (acetylene conversion > 99%) under the assumption that the Pd-only catalyst had no influence on hydrogenation selectivity; neither was any correlation found between selectivity and extent of β-Pd hydride formation.

TL;DR: In this article, the presence of co-adsorbed CO and changes in the surface structure of Pd-Ag surfaces together with high temperature reduction have been shown to alter the reaction behavior of an industrially significant selective hydrogenation reaction.

TL;DR: In this paper, a detailed application of X-ray spectromicroscopy to chemical analysis of polymers is reviewed and a detailed approach for quantitative analysis for polyurethanes is presented.

TL;DR: In this article, the design and performance of a scanning transmission x-ray microscope (STXM) at the Advanced Light Source (ALS) is described, making use of a high brightness undulator beamline and extending the STXM technique to new areas of research.
