The vast majority of crystal structures are determined by x-ray or neutron diffraction. However there are instances when conventional techniques cannot be used and electron diffraction enables crystal structures to be determined from sub-micron crystallites. Over the past decade, precession electron diffraction has become the preferred method to acquire electron diffraction data as it maximizes the data collected and minimises the effects of dynamical diffraction that can plague structural solution.

The Group is working in a better understanding of precession electron diffraction and its application to a range of structures, from multiferroic oxides to intermetallics, metal-organic frameworks and pharmaceutical crystals. Click here for examples.

We are also working on novel algorithms for structure solution and refinement. For more information on a novel charge flipping algorithm click here.
