PRODUCTS & SOLUTIONS
TEM ORIENTATION IMAGING
PHASE MAPPING –ASTAR
ASTAR device uses novel TEM based orientation/phase mapping technique to characterize any material down to 1 nm scale based on collection of precession electron diffraction patterns (PED). In combination with TOPSPIN acquisition of orientation / phase / strain/ STEM maps is possible
TEM STRAIN MAPPING ANALYSIS
Novel Automated Strain Mapping Solution for TEM/STEM (Patent pending) based on nanobeam precession diffraction patterns and STEM reference image acquisition. Precision up to 0.02% (200kV FEG) with spatial resolution < 2 nm (FEG TEM). In combination with TOPSPIN acquisition of orientation /phase /strain /STEM maps is possible.
4D STEM WITH TOPSPIN PLATFORM
Scanned acquisition with Precession electron diffraction . TOPSPIN is a digital STEM, beam Precession Electron Diffraction analytical Experimental framework offering a suite of beam precession imaging and advanced analytical experiments.
3D PRECESSION DIFFRACTION TOMOGRAPHY – MICRO ED
3D diffraction tomography in combination with DigiSTAR and precession diffraction device enable automatic reconstruction of reciprocal space, unit cell determination and crystal structure solution of any material
ANALYSIS OF AMORPHOUS MATERIALS
e-PDF software suite uses Electron Pair Distribution Function (electron diffraction based technique) that allows to analyze local order in amorphous and nanocrystalline materials from diffuse or ring ED patterns.

Our 3D precession electron diffraction work (combined with direct detection camera) on a very complex organic molecule (Linagliptin drug for Diabetes II desease) is selected as a cover page of the prestigious journal “Crystal Growth & Design”. Title “ Crystal Structure of Linagliptin Hemihydrate Hemiethanolate (C25H28N8O2)2(H2O)(C2H5OH) from 3D Electron Diffraction Data, Rietveld Refinement, and Density Functional Theory Optimization”
This is one of the largest structures solved with ED data in TEM. The structure contains 35 non H atoms in the molecule (there are 2 molecules in the asymmetric unit). More information on : https://doi.org/10.1021/acs.cgd.0c01379
NanoMEGAS is partner of the European Network for Transmission Electron Microscopy with expertize in electron difffraction/crystallography techniques and TEM orientation imaging

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.
