Complementarity of advanced TEM to bulk diffraction techniques
2 likes537 views
The document presents the integration of advanced transmission electron microscopy (TEM) with bulk diffraction techniques to study nanoscale structures, involving collaborations with various academic institutions. It covers several research findings, including electron diffraction and structure determination of complex materials such as lithium-based batteries and multiphased samples. The lecture is associated with multiple publications and acknowledges contributors and collaborators in the field.
