DESCRIPTION:Over the past few years STEM-based electron tomography has bec
 ome an almost-routine method to examine the 3D structure of materials at t
 he nanoscale. There have been significant advances in terms of optimal acq
 uisition strategies (e.g. sub-sampling and in-painting) and reconstruction
  algorithms. The adoption of iterative reconstruction techniques and more 
 recently compressed sensing methods has led to greatly improved reconstruc
 tion fidelity by incorporating known (prior) information or comparable fid
 elity using greatly reduced data sets.\n\nRecently\, with the introduction
  of more efficient spectrometers and cameras\, and with a vast increase in
  computer power\, analytical electron microscopy / tomography has yielded 
 new quantitative nanoscale information about the crystallography\, composi
 tion\, chemistry and electric\, magnetic and optical properties through th
 e acquisition of ‘multi-dimensional’ data sets. This has been accompli
 shed by combining different modes of electron microscopy\, exploring real 
 and reciprocal space\, energy and time. I will discuss how this is best im
 plemented\, reviewing the state-of-the-art in multi-dimensional microscopy
  and look forward to how these techniques might be developed further for a
 utomated data collection and analysis.\n\n*This talk will be held online u
