Group theory crystallography
WebCrystallography is the experimental science of determining the arrangement of atoms in crystalline solids.Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics).The word crystallography is derived from the Ancient Greek word κρύσταλλος (krústallos; "clear ice, rock-crystal"), with its … WebApr 4, 2024 · In 2024 the group found that macromolecules could be refined down to sub-ångstrom resolution (Clabbers et al., 2024). Mauro Gemmi, the Principal Investigator for Electron Crystallography at the Instituto Italiano di Tecnologia in Pisa, was one of the first researchers to utilize precession electron diffraction to solve crystal structures.
