NEW WEBINAR
ASTAR: Phase & Orientation mapping
at nm scale by 4D – SPED in TEM

December 2nd, 2020, 10:00-12:00 AM CET
The webinar will cover an introduction to Precession enhanced Phase & Orientation mapping for TEM (4D-Scanning Precession Electron Diffraction – 4D-SPED*). ASTAR system uses series of PED diffraction patterns of a scanning area of interest and a template matching approach to generate orientation and phase maps (up to 1-3 nm resolution).
Various materials as metals, alloys, minerals, nanostructures etc can be studied by ASTAR. Moreover, using common or interactive Virtual Bright Field images and Correlation Coefficient Map tools, superimposed secondary phases, hidden dislocations /defects and amorphous areas can be clearly highlighted locally in the material under studied at nm scale. Grain size distribution and texture analysis are further important tools to shed light to your materials local properties.Recent examples of ASTAR method will be presented. We hope you take this opportunity to learn about this advanced technique for TEM and visualize the wide range of exciting results obtained by 4D-SPED (ASTAR).
*4D SPED method is precession enhanced 4D-STEM technique

ESTEEM3 – Enabling Science and Technology through European Electron Microscopy – is an EU funded project for electron microscopy, which aims at providing access to the leading European state-of-the-art electron microscopy research infrastructure. Facilitating and extending transnational access services of the most powerful atomic scale characterization techniques in advanced electron microscopy research to a wide range of academic and industrial research communities for the analysis and engineering of novel materials in physical, chemical and biological sciences.
ESTEEM3’s objective is to deliver access to users coming from a wider range of disciplines. Transnational Access (TA) to ESTEEM3 centers is obtained through a transparent, simple peer review process based on merit and scientific priorities. Optimum service to users is supported by Networking Activities (NA) and Joint Research Activities (JRA), which address key issues such as specimen preparation, data interpretation, treatment and automation through theory and simulation, and standardization of protocols and methodologies.
