Solid-state thermochromism in an octahedral CoII complex studied by X-ray powder diffraction

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...

Zeolite Structure Analysis with Powder X-ray Diffraction and Solid-state Nmr Techniques

Large advances in the development of catalytic materials were made with the synthesis of zeolites, which are porous crystalline materials that can be used as catalysts, catalyst supports, sorbents and ion exchangers. Zeolite structures consist of T-atoms tetrahedrally coordinated to oxygen atoms, where T can be AI, Si, or any other element capable of isomorphous substitution for Si. The unavail...

Fate of nickel subsulfide during carcinogenesis studied by autoradiography and X-ray powder diffraction.

Sarcomas in mice were induced by i.m. and s.c. administration of 63Ni- and 35S-labeled nickel subsulfide (Ni3S2), and the fate of the Ni3S2 was studied in tumors and normal tissues during carcinogenesis. Whole-body autoradiography showed a gradual loss of solubilized 63Ni and 35S radioactivity from the site of injection. There was also a loss of nonsolubilized dust particles which appeared to b...
