Apart from the apparent manipulation of the x-ray refinement, many aspects of the original article should have aroused suspicion. Any long paper with 66 citations should be returned for revision. The paper claims to optimise the heating of magnetic nanoparticles dispersed in a biological medium su

Dear Rietveld users I have some data collected on a synchrotron line on reflection mode. The sample is an ancient steel (Fe alpha + Fe3C). The aim is to analyzed Fe/Fe3C in order to get the carbon content. The total scattering volume is obviously not constant with 2 theta. We can observe an

Hi Francois Reflection mode at a synchrotron? Does that mean you have the beam coming in at a fixed angle with respect to the specimen, and then collecting all the angles? Because of the change in specimen volume with angle, you need to modify the calculated intensities, as most (all?) Rietveld p
