Miller & Bragg

Interactive crystallography from Miller indices to X-ray diffraction.

Use it online: https://nockemann-lab.github.io/miller-and-bragg/

An interactive, single-file teaching tool for Miller indices and X-ray diffraction, for undergraduate and taught postgraduate courses in chemistry, materials science, physics and engineering.

• Draws the section of any lattice plane inside a unit cell and takes students through indexing one step at a time
• Generates matching exercises, question banks for Canvas and Moodle, and printable worksheets
• Covers tetragonal, orthorhombic and hexagonal (Miller–Bravais) cells
• Links planes to diffraction: a Bragg's law simulator with a simulated powder pattern, a powder-indexing exercise, and single-crystal diffraction with the Ewald construction and rotation photographs
