Determination of the accuracy of phase analysis measurements on spherical surfaces through X-ray diffraction

Synthesis and characterization of spherical 2-diazo-4,6-dinitrophenol (DDNP)

“…On the one hand, traditional DDNP has coarse and unregulated crystal faces, making the probability of getting incident light equal, but spherical DDNP has smooth integrated surfaces, uniform particle distribution and compact texture, only certain crystal faces has higher probability for getting incident light [18]. On the other hand, traditional DDNP has many petal-like glomerocrysts and twinned crystals, and this polycrystalline structure leads to the divergence and extinction of incident light with the result that the peak intensity of XRD decreases with increasing FWHM of peaks [19,20]. Therefore, we can draw a conclusion that spherical DDNP has less crystal defects inside particles than traditional DDNP from the results of XRD patterns.…”

Nondestructive residual stress depth profile analysis at the inner surface of small boreholes using energy-dispersive diffraction under laboratory conditions

“…Much theoretical and experimental work has been done to investigate the influence of the above-mentioned effects. Many authors examine only some of these effects, such as the translation and/or absorption effect (Doig & Flewitt, 1978a,b;Dowling et al, 1988;Yu & Zhang, 1989;Berruti & Gola, 2003;Rivero & Ruud, 2008) or the rotation effect (Willemse & Naughton, 1985). A holistic theoretical approach, which includes translation and rotation effects as well as absorption and shadowing, was formulated by François et al (1995) and Dionnet et al (1996Dionnet et al ( , 1999.…”
