The structure of poly(D-(-)-.beta.-hydroxybutyrate). A refinement based on the Rietveld method
Macromolecules, 1988The crystal structure of optically active microbial poly(D(-)-beta-hydroxybutyrate) has been refined with the Rietveld whole-fitting method applied to powder X-ray diffraction data. This natually occurring polymer gives rise to a very crystalline phase and therefore to very detailed and resolved powder profiles.

Structure refinement of large-pore aluminophosphate molecular sieve, H1, by Rietveld methods
Zeolites, 1993Abstract The structure of HI, a large-pore molecular sieve, is analyzed using X-ray powder diffraction data collected on two samples from separate preparations. Data for one of the samples, H1-A, prepared using a combination of tributylamine and dipentylamine was collected using a synchrotron source, whereas for the other sample prepared using ...

Abstract The advent of fast computing allows more computationally expensive, though possibly more accurate, approaches for estimating uncertainties on Rietveld refined parameters. Here we compare three such methods, using two different refinement programs, FullProf and GSAS.

Refining real structure parameters of disordered layer structures within the Rietveld method
Zeitschrift für Kristallographie Supplements, 2008A new approach is proposed for the refinement of disordered layered structures within the Rietveld method. It is shown that it is possible to introduce the existing recursive treatments of stacking disorder in a Rietveld refinement by using a supercell approach in combination with a complex manipulation of the structure factor calculation.

AIP Conference Proceedings, 2019
Synthesis and structural characterization of powdered (La1.2Sr0.8)InMnO6 were made using the coprecipitation method. The prepared samples have a orthorhombic structure corresponding to the space group P n m a (62). X-Ray diffraction and full pattern fitting through Rietveld method were used for structural characterization.

Abstract The structure of NaPb 9 (PO 4 ) 6 F(H 2 O) 0.33 , isostructural with apatite, was determined by X-ray powder diffraction methods and the result of Rietveld refinement is P 6 3 / m , a = 9.76396(8) A and c = 7.27520(9) A. The final refinement led to R F = 5.4%, R B = 6.6%.

Refinement of the structure of hydrogen–vacancy complexes in titanium by the Rietveld method
Physics of the Solid State, 2016The VT1-0 titanium alloy (phase α-Ti) with various hydrogen and hydrogen-vacancy concentrations has been studied. The stability of the 32-atom Ti–nV–mH supercell (n is the number of the V vacancies, and m is the number of hydrogen atoms H) with varying numbers of vacancies and hydrogen atoms has been calculated from the first principles. The structural

International Journal of Mineral Processing, 2015
Mineral processing tailings are complex mixtures of minerals residual from the parent ore and minerals formed during processing. The number of minerals present in tailings samples, and their unusual composition and structure compared with minerals naturally occurring at the Earth's surface, poses challenges for quantification of mineral concentrations.
