How to reconstruct 3D chemical map from confocal micro XAFS

A research group led by Professor B. Kanngießer (Technische Universität Berlin, Germany) has reported on a new approach for chemical speciation in stratified systems using 3D Micro-XAFS spectroscopy. As X-ray fluorescence mode in XAFS measurement generally leads to distorted spectra due to absorption effects, they developed a reliable reconstruction algorithm. For more information, see the paper, "Reconstruction Procedure for 3D Micro X-ray Absorption Fine Structure", L. Lühl et al., Anal. Chem. 84, 1907 (2012).
