A century has passed since the first X-ray diffraction experiment (Friedrich et al. 1912). During this time, X-ray diffraction has become a commonly used technique for the identification and characterization of materials and the field has seen continuous development. Advances in the theory of diffraction, in the generation of X-rays, in techniques and data analysis tools changed the ways X-ray ...

236-1 Fig.1 Schematic drawing of the apparatus for X-ray diffraction experiment. (A) Specimen was placed between two parallel discs, one of which was rotated with a constant rate (0-5 s) Through a chamber window made of Kapton film, X-ray beam was introduced through the specimen suspension and diffraction signals from aligned filaments were recorded with a Hamamatsu cooled CCD camera (camera le...

X-ray diffraction (XRD) technique is commonly used for qualilative ana lysis of minerals, and has also been successfully used for quantitative measurements. In this research, the matrix fl ushing and a new X-ray diffraction method have been used for the determination of crystallinity and amorphous content of Opal and Quartz mixture. The PCAPD is used to detemline the quanti tative analysi...

A simple method has been employed to synthesize Copper and Copper oxide nanoparticles from Copper (II) succinate precursor by thermal decomposition method using oleylamine as a capping agent. The particles synthesized with oleylamine and triphenylphosphine were well dispersed nanoparticles obtained from X-ray Diffraction (XRD). The Synthesized copper nanoparticles were characterized by UV-Visib...
