Relaxor ferroelectrics have useful behaviour not yet fully understood. We used electron diffraction to show that ferroelectric behaviour in PST is actually due to two coupled antiferroelectric modes.

Nanowires should be defect-free since they expel defects with strain fields. However, we found new types of defect with zero Burgers vector and no strain field in GaAs nanowires.

"Pint of Science" is returning from the 20-22nd May 2019, in various pubs across Coventry and Warwickshire. The 2018 festival involved a number of staff and students from Physics, and the call for speakers and volunteers for 2019 is now open.

Tests of quantum coherence could demonstrate biological systems exploiting quantum phenomena. This paper discusses such tests and how the role the environment must be considered to witness coherence.
