Crystallographic Theory

The majority of viruses have protein containers, called capsids, in which proteins are arranged with icosahedral symmetry. The capsids of these viruses follow structural blueprints that can be modelled as subsets of 3-dimensional aperiodic lattices called quasicrystals. These, in turn, can be obained by projection from 6-dimensional Bravais lattices. In this work we apply the crystallographic theory of phase transitions to these 6D lattices, and via projection of these results derive information on the structural transitions of viruses important for infection.

An exploration of the crystallographic theory of the relatively novel method of Microcrystal Electron Diffraction (MicroED), via comparison to X-ray crystallography at the theoretical and practical level as it applies to biological macromolecules. We then attempt to outline the limitations and challenges that the technique currently faces in structural biology, and suggest future areas of study that may improve and optimize the technique.

ABSTRACTA new crystallographic theory of interfacial structure is applied to the case of interfaces between NiSi2, CoSi2 and Pd2Si grown epitaxially on Si. In the case of NiSi2 layers grown in parallel orientation it is shown that dislocations with Burgers vectors ¼<111> separate energetically degenerate interfacial domains on {hko} interfaces. Observations, of such defects on (001) interfaces, using transmission electron microscopy, are presented and show detailed agreement with the theory.
