Rietveld Refinement: Practical Powder Diffraction Pattern Analysis Using TOPAS
In their paper 'Lens-free holographic imaging for on-chip cytometry and diagnostics', the team described how, by controlling the spatial coherence of the illumination source, they recorded a 2D holographic diffraction pattern of each cell or micro-particle on a chip using a high resolution sensor array that has 2 [micro]m pixel size.
The refined diffraction pattern of the Co-17Re-23Cr alloy with 25% Ni after ST heat treatment taken at RT reveals the following phase composition: ~3% hcp ([epsilon] Co-[P6.sub.3]/mmc with a~2.56 [Angstrom] and c~4.15 [Angstrom]) and 97% fcc ([gamma] Co-Fm-3m with a~3.161 [Angstrom]).
Finally, use the X-ray diffractometer (D8) to scan the prepared sample powder to obtain a full X-ray diffraction pattern which can do both phase analysis and quantitative analysis.
The intensity of the X-ray diffraction pattern peaks was recorded while varying the 2[theta] angle from 2[degrees] to 155[degrees] under irradiation with Cu-[K.sub.[alpha]] rays at a wavelength of 1.5405 [Angstrom].
In addition, it can be established that the firing temperature was higher than 700[grados]C since no reflecting planes of clay or calcite phases were observed in the diffraction pattern. The presence of quartz and feldspar in the material would favor its use as a degreaser and in turn maintain ceramic stability at temperatures above 1000[grados]C (22, 23).
The researchers then measured the cubic structure of the ice by shining a high-intensity X-ray laser into the frozen droplets created in the nozzle and examining the diffraction pattern on an Xray camera.
The diffraction pattern, in this case, is a manifestation of different times bleeding through one another.

The intensity and vorticity of the POVs are measured with a CMOS camera and the far-field diffraction pattern through an equilateral triangular slit, respectively.
