  1. Diamond Cubic

    Once upon a time I analyzed electron diffraction patterns. They looked like this: Electron Diffraction Patterns, public domain images colored in "matrix green". These patterns are the inverse of the crystal lattices, sort of. The regularity of the dots represents the symmetries of the physical crystal. To identify the material causing a certain pattern, you compared it with sample patterns in a "database". I am using quotes as the database was a drawer cabinet from wood. You sifted […]

  6. Chocolate (specifically cocoa butter) actually has multiple crystalographic forms (polymorphs), tempering is all about controlling which one (the hard shiny one is β(V)). But since it's crystals, we have the technology to resolve their stractures!

  16. @sflorg #Structuralbiology is an important #basicresearch direction that aims to gain information about dynamics and interactions of #biological molecules. This research relies on high-tech, including #cryoelectronmicroscopy (EM), nuclear magnetic resonance (#NMR) spectroscopy, and X-ray #crystallography. Goals are a better understanding and e.g. the creation of #molecular #dynamicssimulations.

  21. Installation of tRNA modifications is key to protein synthesis.

    In her presentation at #Biochemistry2026, Carine Tisné presented her group's in depth work on structural and functional studies to understand the underlying processes on the example of m1A.

  27. @famousblueben Ben @famousblueben , and Greg @GPJohnston,
    I got lots of results searching Mastodon for Rockhounding, Geology, Lapidary, RockTumbling, Gemology, Crystallography, etc.

    No rock clubs meeting online, yet, though.

    Different search results with and without intercaps, e.g., rockhounding, and RockHounding. (Why? :blobcatthinkingsmirk: :shrug:)
