Abstract: Some of the advanced EXAFS analysis features of FEFF and FEFFIT are described. The scattering path formalism from FEFF and cumulant expansion are used as the basic building blocks of EXAFS analysis, giving a flexible and robust parameterization of most EXAFS problems. The ability to model EXAFS data in terms of generalized physical variables is shown, including the simultaneous refinement of two different polarizations for Co K EXAFS data of \rm CoPt_{3}.

TL;DR: In situ XAS measurements on a bifunctional manganese oxide catalyst with high electrochemical activity for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) demonstrate that the OER activity scales with film thickness, which suggests that the films have porous structure, which does not restrict electrocatalysis to the top geometric layer of the film.

John J. Rehr,R. C. Albers +1 more
TL;DR: In this paper, the authors focus on extended x-ray absorption fine structure (EXAFS) well above an X-ray edge, and, to a lesser extent, on xray absorption near-edge structure (XANES) closer to an edge.
