Laura Gemmrich Hernández

I started my career in geology in 2015 with a bachelor’s degree in the University of Barcelona (UB). During my bachelor I started working on the study of minerals in the department of Mineralogy, Petrology and Applied Geology. My bachelor’s thesis was on the Geology and mineralogy of the In-enriched Huari Huari deposit (Potosí, Bolivia). After finishing the bachelor’s degree, I continued with a master in Mineral resources and geological hazards in the UB and the Autonomous University of Barcelona (UAB). I finished my master’s with a thesis on the Trace element composition and U-Pb ages of Bolivian Tin Belt cassiterite. The following year I worked as assistant curator in the Natural Sciences Museum of Barcelona with the scientific mineralogy collection.


Amatassalam Ben Meriem

I am a PhD student at Basel University in the field of electron diffraction of biological single molecules and nanocrystals. I started my physics studies in 2016 at the University of Lorraine (France) and obtained my master’s degree in Condensed Matter and Nanoparticles in July 2021.

My educational background puts more emphasis on the field of nanophysics in its theoretical, experimental, and numerical aspects. During the M1 internship I have done at the Jean Lamour Institute in Nancy, I worked on a subject called “Idles waves in high-performance computing and comparison with kinematic waves”. Dealing with the challenges scientists have to face while solving some equations that require the help of supercomputers, the purpose of this study was to investigate the possibility to best describe, in the light of kinematic waves theory, the delays generated by the accumulation of data during their exchange among the processors.

In my second year of master, I chose to focus on the experimental side of my studies, so I specialized in crystallography and experimental techniques in nanoscience. With a team of searchers, Post-Doc and PhD students from the Jean Lamour Institute, I had the opportunity to work on the elaboration of a magnetic captor from the choice of the materials to the test of its inherent capacities. This included the use of one of the latest and most advanced devices and techniques, such as molecular beam epitaxy (in the DAUM tube), surface and properties analysis (Vibrating-sample magnetometry, HR-TEM…) and lift-off methods. Then, I concentrated more on the structural and magnetic analysis of a NO-releasing agent used as a drug to relax blood vessels: the Sodium nitroprusside. In order to collect that information, X-rays (through single-crystal and powder) and neutrons diffraction experiments have been led.

I discovered crystallography in 2019, the last year of my Bachelor of Fundamental physics when working with a biologist on the structural analysis of a protein from the GST family (Tau class). To learn crystallization techniques, I trained over the lysozyme to find the optimized conditions to grow crystals. As much as too concentrated or too dilute samples can result in either amorphous precipitate or clear drops when performing a PCT (pre-crystallisation test), to carry out a doctorate project is a work of details. Trying to find the right balance between hard work and enthusiasm is the challenge I launched myself, alongside the motivated, qualified, and welcoming Jan Pieter Abraham’s team.


Erica Cordero Oyonarte

Erica Cordero Oyonarte graduated in Chemistry at Complutense University of Madrid (2017) and obtained her master degree in Molecular Nanoscience and Nanotechnology at Autonoma University of Madrid (2019). During her master thesis she was a researcher assistant at CSIC (Institute of Ceramic and Grass) studying different nanocomposites and their functional hybrids for fluorescence imaging applications where she could work with different techniques such as X-Ray diffraction and transmission electron microscopy to characterize the nanoparticles mentioned above. In 2021 she started a project in the Department of theoretical physics at UNED related to the study of nanometric materials (Niobium doped aluminium clusters) to hydrogen storage through numerical simulations by SIESTA method. Thanks to this experience she was able to achieve a deeper knowledge of programming languages (specially Fortran). Due to her work experiences in different laboratories, she has started a PhD in a European program (Marie Sklodowska–Curie) and more specifically in the project “Electron crystallography of nanoparticles” where she will be able to synthesize TiO2 structures with different nanoparticle size, determining the minimal beam and crystal size at which it is possible to collect 3D ED data suitable for structure solutions and refinements, developing a specific experimental set up for 3D ED data collection with parallel nanobeams, and comparing the structure obtained from Rietveld refinement on power x-ray data with dynamical refined structure from 3D ED data. Thank to this project she could be joining to a new generation of electron crystallographers.


Sara Passuti

Sara Passuti got her Bachelor degree in Optics and Optometry at the University of Florence in 2018, with a thesis work in psychophysics conducted at the Italian Institute of Optics (INO-CNR), aimed at the assessing of ocular accommodative astigmatism.

In 2021 she got her Master degree in Materials and Nanotechnology at the University of Pisa, where she firstly got close to electron diffraction and crystallography. During her internship in the IIT group at the NEST Laboratory in Pisa, she explored solvothermal and mechanochemical synthesis of Metal-Organic Frameworks (MOFs) and characterized them through X-Rays Diffraction (XRD) and Transmission Electron Microscopy with Precession Electron Diffraction Tomography (PEDT).

She decided to continue on the road of electron crystallography by applying to the European NanED doctoral fellowship. She is now working on the project “Electron crystallography of nanodomains in functional materials” at CRISMAT Laboratory (CNRS) in Caen (France), where she is analyzing thin films and ceramic materials through Electron Diffraction.

Her aim in the context of this project is to strengthen her skills in the field of Electron Diffraction in order to contribute to the progress of these techniques and to the expansion of their applications.


Marco Santucci

Marco Santucci studied Materials and Nanotechnology at the University of Pisa (Italy), Department of Civil and Industrial Engineering, where he obtained his MSc degree in 2020, with an MSc thesis on the “Optimization and Evaluation of Noble Metal / Transition Metal Oxide Nanocatalysts for Hydrogen Generation” developed at the laboratory of the Center of Nanotechnology Innovation@NEST, a centre of the Istituto Italiano di Tecnologia network in Pisa. Supervisor: Prof. M.Gemmi, Dr. V.Voliani. Santucci earned a BSc in Chemistry at the University of Florence (Italy) in 2018, with a BSc Thesis on “Spectroscopy Study of the High-Pressure Crystallization of Stoichiometric Crystals of Methane Hydrate Phases I and II” developed at the LENS laboratory in Florence. Supervisor: Prof. R.Bini, Dr. S.Fanetti.


Lei Wang

Lei Wang got his Bachelor degree in Chemical Technology at Zhengzhou University in 2018. Then he got his Master degree in Environmental Engineering at Zhengzhou University and joint education by Dalian Institute of Chemical Physics in 2021. The aim of his Master project was to investigate the host-guest interactions between molecular sieve frameworks and organic structure-directing agents (OSDAs), which would direct the synthesis of desired molecular sieves. During his study, he learned the knowledge of crystallography in both powder X-ray diffraction (PXRD) and electron diffraction (ED).

He continued his study of electron crystallography at Stockholm University by applying to the European NanED project. He is now working on the project and developing electron diffraction methods used for protein-ligand interactions at nanoscale. He is expected to solve protein structures with different ligands and enable the method in structure-based drug discovery.
