Two-dimensional X-ray powder diffraction

Automated parametric Rietveld refinement and its application to two- dimensional X-ray powder diffraction experiments

Sponge-like Reversible Transformation of a Bimetallic Cyanometallate Polymer

Two new cyano-bridged Ru-Cu polymers, the one-dimensional chain {[Cu(tnH)2(H2O)2][Ru(CN)6] ·2H2O}∞ (1) (where tn ) 1,3-diaminopropane) and the pseudo-two-dimensional network {[Cu(tnH)2][Ru(CN)6]}∞ (2), have been prepared and fully characterized. Compounds 1 and 2 both crystallize in the same monoclinic space group, P21/n. Complex 1 was characterized by single crystal X-ray analysis, and compoun...

A portable powder-liquid high corrosion-resistant reaction cell for in situ X-ray diffraction and absorption studies of heterogeneous powder-liquid reactions and phase transformations

A portable powder-liquid high corrosion-resistant reaction cell has been designed to follow in situ reactions by X-ray powder diffraction and X-ray absorption spectroscopy techniques in transmission mode. The cell has been conceived to be mounted on the experimental stations for diffraction and absorption of the Spanish CRG SpLine-BM25 beamline at the ESRF. In the case of the diffraction techni...

Three-dimensional electron diffraction as a complementary technique to powder X-ray diffraction for phase identification and structure solution of powders

Phase identification and structure determination are important and widely used techniques in chemistry, physics and materials science. Recently, two methods for automated three-dimensional electron diffraction (ED) data collection, namely automated diffraction tomography (ADT) and rotation electron diffraction (RED), have been developed. Compared with X-ray diffraction (XRD) and two-dimensional...

A New Analysis Method for Two-dimensional X-ray Data

Improvements in X-ray optics and detectors have led to unprecedented challenges in interpreting diffraction information. One challenge is obtaining strain results from Debye-Scherrer rings originating from a few grains of material. In addition, results are typically desired from multiple rings over hundreds or thousands of exposures. Current two-dimensional analysis methods build on existing on...
