Scanning precession electron diffraction data analysis approaches for phase mapping of precipitates in aluminium alloys.

Mapping the spatial distribution of crystal phases with nm-scale spatial resolution is an important characterisation task in studies of multi-phase materials. One popular approach is to use scanning precession electron diffraction which enables semi-automatic phase mapping at the nanoscale by collecting a single precession electron diffraction pattern at every probe position over regions spanning up to a few micrometers. For a successful phase mapping each diffraction pattern must be correctly identified.

Medication and participation: A qualitative study of patient experiences with antipsychotic drugs.

Patient autonomy is recognised within mental healthcare, although the capacity to participate in one's own treatment planning is often reduced during a psychotic crisis. The patient may not be sufficiently competent to give consent or express preferences at the time treatment decisions are made. Nine participants were interviewed shortly after a crisis.
