TL;DR: Beamline 10.3.2 at the ALS is a bend-magnet line designed mostly for work on environmental problems involving heavy-metal speciation and location, which offers a unique combination of X-ray fluorescence mapping, X-Ray microspectroscopy and micro-X-ray diffraction.

TL;DR: Scanning X-ray microdiffraction (microSXRD) combines the use of high-brilliance synchrotron sources with the latest achromaticX-ray focusing optics and fast large-area two-dimensional-detector technology to study thin aluminium and copper blanket films and lines following electromigration testing and/or thermal cycling experiments.

TL;DR: The speciation of Zn and Ni in ferromanganese nodules from loess soils of the Mississippi Basin was determined by a synergistic use of three noninvasive synchrotron-based techniques, providing a new method for determining trace metal speciation in both natural and contaminated environmental materials.

TL;DR: The availability of high brilliance third generation synchrotron sources together with progress in achromatic focusing optics allows us to add submicron spatial resolution to the conventional century-old x-ray diffraction technique as discussed by the authors.

TL;DR: A large number of Sn whiskers have been found on the Pb-free solder finish on leadframes used in consumer electronic products as mentioned in this paper, and the growth direction of whiskers is known to be a stress relief phenomenon.
