Neutron and X-ray powder diffraction investigation of LaMnO3

X-Ray Powder Diffraction Metrics

To compare sample data from x-ray diffraction a suitable metric is developed to evaluate the similarity (or dissimilarity) between samples and to compare it to a references. The methodology focuses on the d-lines and uses the intensity measurements indirectly in the algorithm. The resulting d-line distribution and summary statistics of the differences is used to establish whether a true differe...

Resonant X-ray Scattering and Multiple Beam Diffraction in LaMnO3

Fig 1: The solid points give the location and shape of the (1 0 –4) resonant reflection in orthorhombic LaMnO3. Open circles display Mn Kα fluorescence from the same sample on a common energy scale. The vertical scale is arbitrary and the lines are guides to the eye. In conventional X-ray diffraction the beam scatters from all electrons in the unit cell, but in resonant diffraction at a forbidd...

Two-dimensional X-ray powder diffraction

X-ray powder diffraction on proteins

Macromolecular structures are traditionally determined by means of single crystal X ray diffraction from protein crystals of micrometer dimensions. Nevertheless, the growth of good quality single crystals can be very difficult or even impossible, especially in cases of large proteins, membrane proteins or protein complexes. Modern developments of X-ray powder diffraction have allowed the struct...

X-ray single crystal and powder diffraction: possibilities and applications

In this article the main possibilities of single crystal and powder diffraction analysis using conventional laboratory x-ray sources are introduced. Several examples of applications with different solid samples and in different fields of applications are shown illustrating the multidisciplinary capabilities of both techniques. Handbook of instrumental techniques from CCiTUB X-ray single crystal...
