X-ray spectromicroscopy in soil and environmental sciences

J. Thieme, J. Sedlmair, S.-C. Gleber, J. Prietzel, J. Coates, K. Eusterhues, G. Abbt-Braun and M. Salome

Synopsis: X-ray spectromicroscopy is a tool excellently suited to studying materials from geo- and environmental sciences, and combines high spatial resolution with high spectral resolution, thus connecting morphology with chemistry. Using tomography or the newly developed coherent diffraction imaging, three-dimensional information about the structure of samples on the micro- and nanoscale can be obtained.
