Sara’s Poster Prize at IWT2023

Caen, France - April 12-14, 2023


Sara Passuti won the Poster Prize at the International Workshop on Thermoelectrics Materials IWT2023 that took place in Caen (FR)

She presented her work about "3D Scanning Precession Electron Diffraction Tomography of nanodomains in thermoelectrics".

Starting from the results obtained by 3D ED on interconnected Enargite-Stannite Cu2+xMn1-xGeS4 nanocomposites that we find in the recent publication of Pavan Kumar V. et al (2022), she explored the possibilites for a more detailed analysis of these thermoelectric samples by combining scanning electron diffraction techniques, such as orientation mapping and Scanning Precession Electron diffraction Tomography (SPET). In particular, by means of this last technique, she's investigating the possibility of an accurate structure solution of different nanodomains in the sample with a single acquisition. 

The data were acquired with the TEM facilities at Crismat (JEOL F200 200 kV), and in collaboration with TESCAN with the new TENSOR 100 kV Analytical 4D-STEM

Lei Wang takes his secondment at AstraZeneca @AstraZeneca

Göteborg, Sweden, 7 February – 24 March, 2023


Lei Wang, NanED PhD student (ESR 10), is taking his first secondment at AstraZeneca, Göteborg. This secondment aims to study protein-ligand interactions and experience the real life of an industrial company.

In AstraZeneca, Lei Wang learned how to do drug soaking, crystal fishing and ligand refinement based on large crystals and synchrotron data under the supervisor of Helena Käck. A new protein crystallization method developed by SU was also employed to make small protein crystals in the lab, and MicroED data was collected.

Life in AstraZeneca is pleasant. The working time is usually effective and people in AstraZeneca have a good balance between work and leisure.

Thanks to Helena’s kind help, everything worked out well!

NanED Workshop II - Imperfect crystals, complementarity with PXRD, intellectual property and patent in Science

Mainz, 6 - 8 December, 2022

Workshops JGU

From the 6th to the 8th of December 2022, the NanED project had its second workshop, held in Mainz at the Johannes Guthenberg University.  

The workshop's main goal was to teach NanED PhD students how to use powder x-ray diffraction (PXRD) as a complementary tool to 3D ED. The students learned how to solve structures using PXRD and how to refine them with the Rietveld method. As a second topic, the workshop dealt with the problem of investigating disordered structures. The students had the possibility to learn how to treat diffuse scattering both in PXRD and 3DED using the most novel PDF approaches. The workshop hosted several external experts in PXRD and diffuse scattering such as R. Dinnebier of MPI Stuttgart, M. U. Schmidt of Frankfurt University,  N. Barrier of CNRS Caen, J. Plasier of Elettra Sincrotrone Trieste, R. Nieder of Erlangen University, E. Schmidt of Bremen University, C. Cuocci of Istituto di Cristallografia CNR Bari, S. Plana Ruiz of University Rovira I Virgili Tarragona. 

The workshop was designed with theoretical lectures in the morning and practical sessions in the afternoon, where the students could learn how to use the most advanced software for PXRD data analysis and had the opportunity to visit the 3D ED facilities of JGU

In order to expand and improve their soft skills, the students followed a lecture about the intellectual properties and the patent in science held by T. Einfeld of BASF.

Identifying nanodomains in a nanomaterial using 3D ED

September 19, 2022


The first paper involving the work of one of NanED PhD students is already out! A research group led by CRISMAT-CNRS laboratory synthesized a series of self-doped compounds Cu2+xMn1-xGeS4 through Cu substitution to Mn. Using a combination of powder X-ray diffraction, high resolution transmission electron microscopy and precession-assisted electron diffraction tomography, they evidenced that the materials are composed of interconnected enargite- and stannite-type structures, via the formation of nanodomains with a high density of coherent interfaces. The complex crystal chemistry of such nanocomposites rises the issue of the role of the two structures and of their interfaces in the mechanism governing their electrical and thermal conductivities. Sara Passuti (ESR12 working at CRISMAT CNRS in Caen France) has analyzed and identified the structure of both stannite and enargite nanodomains using 3D ED in these complex intergrown nanocomposites. The paper is just out on Angewandte Chemie. Well done Sara!

NanED Workshop I - Data processing and structure refinement

Prague 25 - 27 May, 2022

FZU Workshops

From the 25th to the 27th of May 2022, the NanED project had its first Workshop, held in Prague at the Institute of Physics of the Czech Academy of Sciences.

The workshop's main goal was to teach NanED PhD students how to collect reliable 3D ED data and how to process these data for a successful structure solution and refinement. The workshop was divided into morning theoretical sessions and afternoon practical sessions to learn how to use all the available structure analysis software for 3D ED. Together with most of the NanED supervisors, we had two invited speakers from outside the project, Prof. Tim Gruene from Vienna University a crystallographer expert in the use of SHELX and Dr Gerhard Hofer of Stockholm University a master in protein crystallography. It was the first we gathered together in person and it has been a fantastic experience for all of us.

Cryo measurements started in JGU

21 April 2022


Working on beam-sensitive and hydrated samples is a complex process. Therefore, Laura Gemmrich Hernandez (ESR08) is currently focused on optimizing the data acquisition routines and sample preparation to get quality data that can lead to the structure solution of such materials.

Currently, the project is focused on microscope management, cryoEM, and data processing of many different types of challenging, organic as well as inorganic, samples; such as hydrated, beam sensitive, and disordered materials. The cryoEM training has included a visit to the BASF in Ludwigshafen (Germany) to learn and practice the vitrification and cryotransfer procedures for these types of samples.

3D ED on disordered structure: ESR9 work is progressing

7 April 2022


Establishing new crystal tracking routines requires a deep understanding of the hardware, software and 3DED technique and its limitations. Due to that, the work of  Marco Santucci (NanED ESR9) is focused in mastering the microscope, with a special eye on the “hidden parameters” that allow the microscope to work. This deep knowledge is necessary to figure out how to handle a basic 3DED experiment, translate it in an automated and technically flexible approach by scripting as well as to improve it.

Marco is focused in the management of the machine, the data collection and processing of organic and inorganic samples, due to their intrinsically different beam stability. Regarding the scripting, Marco is learning Python and DigitalMicrograph© in order to be flexible and synchronize every element of our TEM machines during the data acquisition. Thanks to these acquired competences, Marco will develop a routine to set automatically the best eucentric height, a key parameter for sample mechanical stability during our experiments. At the same time, Marco is also learning how to model disordered crystals and simulate their diffuse scattering using DISCUS, thanks to a visit to the Prof. Rheinard Neder at the FAU in Erlangen.        

Towards the implementation of Scanning RED experiments

11 March 2022


The current objective in the context of Sara Passuti’s (ESR12 @ CNRS) research project is to implement new strategies for diffraction dataset acquisitions for thin films. Differently from a classical Rotation Electron Diffraction (RED) experiment, the beam is scanned across a pre-defined area going from the coating to the substrate of the thin film or vice versa for every tilt angle.

This way, differences in the lattice parameters in distinct areas of the sample could be highlighted and different domains could be identified.

The main issues concern the optimization of the dataset acquisition protocol, making it faster and more efficient, as well as the sorting of the acquired patterns in order to have separated datasets to analyze for different areas of the sample.

NanED PhD students start @Crismat

October 11, 2021


The PhD students Sara Passuti (left) and Erica Cordero-Oyonarte (right) just started at Crismat in Caen their NanED adventure. Sara will work on the project,  “Electron crystallography of nanodomains in functional materials” focusing on materials with amazing properties whose crystallography is extremely difficult due to too small ordered domains. Meanwhile, Erica's project is “Electron crystallography of nanoparticles” which involves studying the limiting size of a 3D ED experiment.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska Curie grant agreement No 956099.
