Fourier-expansion solution of atom distributions in a crystal using X-ray standing waves.
TLDR
Term-by-term Fourier-expansion series are used to reconstruct impurity atom distributions in muscovite mica with respect to the (001) lattice without a priori assumptions on their structures.Abstract:
Term-by-term Fourier-expansion series, each made up of components having element-specific phases and amplitudes acquired with x-ray standing wave measurements on successive orders of Bragg reflections, are used to reconstruct impurity atom distributions in muscovite mica with respect to the (001) lattice without a priori assumptions on their structures.read more

TL;DR: This multitechnique and multiscale approach demonstrates the compatibility of bond-valence models of surface oxygen proton affinities and Stern-based models of the EDL structure, with the actual molecular interfacial distributions observed experimentally, revealing new insight into EDL properties including specific binding sites and hydration states of sorbed ions, interfacial solvent properties, and the effect of solution ionic strength.

Surface structure determination using x-ray standing waves
TL;DR: In this paper, the authors reviewed the application of x-ray standing waves as a means of structure determination with special emphasis on its application to the investigation of adsorbed atoms and molecules at well-characterized single crystal surfaces in ultra-high vacuum.

Bridging arsenate surface complexes on the hematite (012) surface
Jeffrey G. Catalano,Zhan Zhang,Changyong Park,Paul Fenter,Michael J. Bedzyk,Michael J. Bedzyk +5 more
TL;DR: In this paper, the binding site and adsorption geometry of arsenate on the hematite (0, 1 2 ) surface was investigated by high resolution X-ray reflectivity, revealing that two distinct terminations exist in a roughly 3:1 proportion.
