crystallography

Scattering factor of stationary C and Fe atoms plotted as a function of Bragg angle for incident X-ray wavelength of 0.70930 angstroms. Ticks on the horizontal axis correspond to Bragg angle increments of 10 degrees; ticks on the vertical axis are increments of 5 electrons.

from Greek κρυσταλλος − (krustallos) ice, crystal + γραφειν (graphein) − to write

The branch of science devoted to the study of molecular and crystalline structure and properties, with far-reaching applications in mineralogy, chemistry, physics, mathematics, biology, metallurgy and materials science.
