Kind words @ECA_social thank you!  We also wrote up some of the more fundamental exercises in J. Chem. Ed. when pandemic cancelled the 2020 Durham PDRR school:

Great resource to learn about #PXRD, with tutorials on Rietveld analysis in Topas

Durham's powder diffraction schools is legendary! Great that some course material has been uploaded

New YouTube channel with tutorials on Rietveld analysis of powder diffraction data in TOPAS: https://t.co/5KmQhBiYxE
Based on examples from the last PDRR school held at @durham_uni @DurhamChemistry supported by @IUCr @britcryst @PhysicsNews @bruker

Glad you like it, Andrew - particularly the figures. At least 0.75% of them (p318, p603, p605) were drawn with you especially in mind! 😀

Very jealous you have a copy before me (or any of the author team)! Happy to sign for your friend. Standard rate is one author signature per 100 end-of-chapter problems successfully solved.

Thanks Tomce. Glad you enjoyed it!

I had so much fun reading this article by @ivana_evans and @johnsoevans. Definitely among the top 10 papers I've read in 2020. https://t.co/F3o8Kah1pd

[John Evans @johnsoevans]

Delighted that so many people have found the Excel Rietveld paper useful. Thanks to the tutors and students at the Durham powder school who test drove it!

We welcomed @InsideOutCJ to @DurhamChemistry today to film Durham’s @teampigment for an upcoming episode. MChem student Rachael White, @johnsoevans group, showed them how the ancient pigment mosaic gold (SnS2) can be made in a modern laboratory. #DUinspire

@NChemGav @NatureChemistry I won't embarrass him by naming him in public, but Vangelis Papaioannou is my hero!

[John Evans @johnsoevans]

How to build a "perfect" chemical reactor? Use a perovskite of course! Fun collaboration with Ian Metcalfe and team @EngineeringNCL and @esrfsynchrotron.

[John Evans @johnsoevans]

What a good idea! Enjoy, and good luck with the grant.
