Vincentia Emerson Agbemeh

I am Vincentia Emerson Agbemeh from Ghana. I started my journey in Materials Science at the Kwame Nkrumah University of Science and Technology (KNUST) in Kumasi, Ghana where I received my Bachelor of Science degree in Materials Engineering in 2015. My thesis focused on optimisation of laterite-alum ratio for effective fluoride removal in contaminated water. This work was part of a project in the Materials Engineering Department which focused on effective methods for purification of underground water from the Northern part of Ghana which had high levels of fluoride using local and cheap readily available materials in the region. After my bachelor’s Degree, I joined a paint company and worked in the Quality Control Department. I was responsible for testing of raw materials for production such oxide pigments, calcium carbonates in order to meet company standards. My team and I were also responsible for testing and approving production batch for viscosity, particle size and colour.  In 2021, I received my Master of Science degree in Materials Science and Materials Technology at Saint Petersburg Institute of Technology (Technological University), Saint Petersburg, Russia. For my master’s dissertation, I focused of the ZnO based nanocomposites for antibacterial coatings on glass by means of photocatalysis. The method of synthesis used was the polymer-salt method which was an energy efficient, economical and eco-friendly method of nanomaterial synthesis. I am currently working with Professor Mauro Gemmi in IIT, Pontedera, Italy with research focused on 3D ED of organic nanocrystals.

Amirhossein Hajizadeh got his bachelor's degree from the Iran University of Science and Technology in 2015. He studied ceramic materials during his bachelor's and worked on the mechanical properties of ceramic composites.

Later, in 2015, he joined the Corrosion and Protection of Materials group in Tarbiat Modares University devoted his master's to work on the synthesis and electrophoretic deposition of graphene oxide. He focused on the kinetics and mechanism of the electrophoretic deposition process to reveal the unexpected properties of graphene oxide during deposition.

After gaining his master's degree, his interest in electrochemistry motivated him to study electrochemical energy storage. So, he joined the Battery and Sensor group at Materials and Energy Research Center in 2017 and researched the electrophoretic deposition of battery cathode materials for six months.

Thanks to his experience in electrochemical processes, in 2020, he joined the Parthian Battery Company, working as a research and development member on battery materials. During his work, he mainly studied the synthesis of anode materials, e.g., Li4Ti5O12 and nano silicon. Also, he worked on producing spherical graphite and coating anode materials with carbon.

I graduated with a bachelor’s degree in Metallurgical and Materials Engineering at IIT Bhubaneswar, India in 2018. For my bachelor thesis, I started to work on developing a novel method for synthesizing a highly ordered nano-porous Alumina template by a quick single step Anodization of Aluminum.

After finishing my bachelor’s degree, I continued with the masters at IIT Madras, India. As a part of my master’s project with the help of my guide and DAAD Programme, I got an opportunity to do research at Karlsruhe Institute of Technology (KIT), Germany with the project related to the “Effect of strontium (A-Site) addition on structure and properties of perovskite-type high entropy ferrites (Gd, La, Nd, Sm, Y)FeO3, under the guidance and supervision of Prof. Horst Hahn. My work as an exchange student was to synthesize the High Entropy Oxides (HEOs) along with doping of a few metals (Group IIA) and to understand the effect of doping on the structural and magnetic properties. During this project, I have gained knowledge on crystallography in both Powder X-ray diffraction (PXRD) and electron diffraction (ED) along with the Rietveld Refinement of the PXRD data.

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.

Ashwin Suresh

I graduated with a bachelor’s degree in Electrical and Electronics Engineering from Anna University, in 2015 and a master’s in Nanotechnology from SRM Institute of Science and Technology in 2017, Chennai, India.

My master’s thesis was on “Structural and ‎Magnetic Properties of Electrospun Heusler Alloy Nanowires,” this engendered my interest in different nano/micromaterial synthesis and characterization techniques. While doing my thesis, I understood that size, shape, processing temperatures, and ‎material concentration affected the properties of my heterostructures and their behaviour in different ‎conditions. This made me realize that new systems with better manifestations of unique, ‎synergistic magnetic, photonic, and electronic properties can only be envisioned by understanding the microstructural properties and the electron matter interactions of the systems.

I have worked for one year as a junior research fellow (for a project: “Structural investigation of organometallic perovskite materials.”) at ‎SRM Institute of Science and Technology, India. This has provided me with hands-on experience in both Powder X-ray diffraction (PXRD) and electron diffraction (ED) along with the Rietveld Refinement of the XRD data.

I started my PhD in Lukas Palatinus group at the Institute of Physics (Fyzikální ústav – FZU) in Prague as a part of the European NanED Programme (ESR 5) on “Charge density analysis from 3D ED data”. I will be working on validating and optimizing 3D ED data for charge density studies, which will allow the study of bonding effects in different types of materials.
