In collaboration with the University of Leeds, this technical workshop explores how 4D-STEM is enabling a step-change in the structural characterisation of highly beam-sensitive materials. The session is anchored by research from Professor Andy Brown, a recognised leader in analytical transmission electron microscopy, who will guide you through low-dose methods developed for polymeric and organic systems.
Electron beam damage has historically limited how deeply we can explore soft matter at the nanoscale. However, using advanced electron diffraction workflows combining fast beam blanking, direct electron detection, and multimodal STEM instrumentation, new possibilities are emerging.
Co-hosted by Daniel Nemeček from TESCAN, the session highlights the capabilities of TESCAN TENSOR, the only analytical STEM optimized for 4D-STEM workflows enhanced by fully automated beam precession.
Designed for TEM/STEM or EBSD specialists and materials scientists, this webinar brings together academic depth and industrial instrumentation to demonstrate real-world, publishable results.
