Went to a cool BAMPFA exhibit this weekend, on African American quilt making! Recognized one of the patterns as a Truchet tiling, and wanted to know what its FFT would look like. Would the symmetry pop up? Would the diffuse scattering??

That led to this fun exploration of Smith/Carlson/N6 tilings 🧪

🚨 We’re hiring!

Join the Curious Beams Lab at TU Delft as one of our first PhDs and help develop the next generation of diffractive imaging in SEM — pushing surface-sensitive nanoscale characterization to new limits 🔬🧪

Split figures are great for papers. For talks, interactive sliders are better 🙌

Super proud of this work, which showcases modern scientific publishing for open science 🧪

Inspired by the insights of the interactive CTF widgets, we propose a novel phase-retrieval algorithm which achieves robust information transfer on sub-sampled datasets 🙌

Hey there 🦋🧪, we're a new open access microscopy journal and wanted to introduce ourselves! EM aims to modernize scientific publishing for microscopy, by prioritizing open science, transparency, and accessibility and using open-source formats and interactive notebooks 🙌

Attending the APMC 2025 in Brisbane, and interested in learning how to simulate and analyze 4D-STEM data? There's still time to register for the 4D-STEM workshop and learn about strain and orientation mapping, differential phase contrast, ptychography, and more!

Needed to demonstrate this fun example of solving Sudoku puzzles with projection set algorithms for a workshop I'm teaching. Continuously impressed with how easy it is to get to a working demo with wasm + @marimo.io slides 🙌 🧪
