Benchmarking 3D difference PDF Analysis
Measurement of diffuse scattering data and subsequent three-dimensional difference pair-distribution function (3D-ΔPDF) analysis of correlated disorder are compared for in-house and synchrotron sources.

a.k.a. #DiffuseScattering from correlated disorder, veeery correlated... and very substitutional! I cannot see any absences in the hk0; one would need more slices to guess 😄 The extra peaks have a 6-fold point group sym, looks like what is disordered has a 6- or 3-fold sym in its projection along c
With such beautiful large crystals I'm looking forward to seeing what the reciprocal space reconstructions look like and if there's some useful #DiffuseScattering in there!
Lizards are surely among crystallographers' fave pets together with photonic-crystal beetles and forever-twinned sea urchins... but for #DiffuseScattering & #CorrelatedDisorder nerds nothing beats lizards... 🥇💯 physics.aps.org/articles/v15...
Let's go with some single crystal #diffusescattering posting! Glad I have company, we need more reciprocal space beauty around here. Very nice @molecularfoundry.bsky.social 😎
An extended version of Piet Mondrian's renowned artwork "Composition in Red, Blue and Yellow", which consists of a closely packed tiling of rectangles with different length/width ratios. Most of them are white, but a minority are yellow, blue or red, and distributed randomly.
The Fourier transform of the reproduced Piet Mondrian's work, showing a cross-shaped diffuse pattern with a more sharp cross in the middle, dampened by oscillations along the lines. The overall pattern is bright and intense yellow in the centre, then adopting a more smooth red tint, and a darker-blue tone as it approaches the borders of the picture.
As promised, here's the real&Fourier space pair nr 50. This time we explore correlated disorder in an extended version of Piet Mondrian's most famous artwork. Understanding the frequency spectrum is quite an adventure... #diffusescattering #crystallography #reciprocart #generativeart
A single crystal X-ray diffraction image shows a few intensity spots and a distorted web of diffuse, strong intensity streaks.

To make diffuse scattering techniques more accessible, software for data processing called mdx2 has been created that is both convenient to use and simple to extend and modify. #DiffuseScattering #MacromolecularCrystallography #DataProcessing t.co/WhOnF9BH2k
