For those new to Crystallography
- Why bother looking into freely available crystallographic software?
- Crystallography can help answer questions that may not seem very crystallographic at the time.
- In the following screen images, help determine, using diffraction techniques, whether there is Oxygen in the Earth’s outer core. (unit cell volumes to obtain equations of state - EOS)
“O2 volumes at high pressure from KClO4 decomposition: D" as a siderophile element pump instead of a lid on the core.” D. Walker, S.M. Clark, L.M.D. Cranswick, M.C. Johnson and R.L. Jones, (2002), Geochemistry, Geophysics, Geosystems (G^3), submitted
