Dear colleagues, I apologize in advance for attaching a file but I cannot share my astonishment without it.
With so many advanced pieces of equipment for powder diffraction data collection spread all over the world and so many nice pieces of software written to handle (and interpret) powder diffraction data I was truly astonished to see the attached capture of a figure containing powder patterns ready to be published next September 2015 in a reputable international peer-reviewed journal that usually publishes x-ray data, as a proof of phase purity for x<0.4 samples... It´s truly unimportant what is the journal or who are the authors (I can provide the reference if anyone wants it, though), but could anyone think any interesting conclusions can be extracted from samples characterized in this way? Are there referees ready to accept these patterns as proof of anything? Shouldn´t the IUCr take action and try to influence the journals that frequently publish x-ray data (as a complementary characterization technique but that determines the validity of other results) to have well-trained crystallographers review any article that contains x-ray diffraction data? This is not the first time I face this kind of powder patterns in the published literature, that´s why I worry more and more every day.
