Quantum chemistry at the University of Sfax thanks to the ERASMUS+ program

ERASMUS
Chemistry

A practical training course in computational quantum chemistry was organized from May 26 to 30, 2025 as part of an ERASMUS+ collaboration between the University of Sfax and the University of Namur. This inter-university training course for PhD students in chemistry and physics from the Tunisian University brought together more than 20 students.

Université de Sfax

This wonderful initiative is the result of a reflection on the integration of quantum chemistry courses at the University of Sfax initiated by Professors Mahmoud TRABELSI (University of Sfax and alumnus of the University of Namur), Besma HAMDI (University of Sfax) and Benoît CHAMPAGNE (University of Namur). The reflection has been matured over the last two decades, during which time several students from Pr. TRABELSI's team have stayed at Pr. CHAMPAGNE's laboratory.

The aim: to add a computational quantum chemistry component to their research into synthetic chemistry, including syntheses from biobased substances.

A PhD student in chemistry at the University of Sfax, Dhouha ABEIRA, is also involved in the project. She is doing an ERASMUS+ internship in Pr. CHAMPAGNE's laboratory to study the optical properties of molecular crystals.

The program

Students were introduced to the calculation of reaction energies and the simulation of UV/visible absorption spectra. These two applications are typical of activities in quantum chemistry, as they are directly linked to the understanding of reaction phenomena and the development of new compounds for molecular optics.

Emphasis has also been placed on certain technical aspects of the calculations in order to train students in the development of computational protocols according to the questions addressed.

The teaching team

The courses were delivered by an inter-university team.

For the Department of Chemistry at the University of Namur:

  • Professor Benoît CHAMPAGNE, Director of the Laboratoire de Chimie Théorique (LCT) of the Unité de Chimie Physique Théorique et Structurale (UCPTS);
  • Dr. Vincent LIÉGEOIS, for remote IT support and whose suite of programs DrawSuite, a series of applications designed to provide tools for analyzing molecular structures and properties, was much appreciated;
  • Frédéric WAUTELET of the Plateforme Technologique de Calcul Intensif (PTCI) for remote computing support and who has prepared a cluster (pleiades) dedicated to training.

For the University of Sfax Chemistry Department:

  • The Dr. Mohamed CHELLEGUI, from the organic chemistry laboratory, for preparing practical work;
  • Dhouha ABEIRA, PhD student in chemistry, for preparing practical work and assisting students from Sfax.

The teaching teams warmly thank the International Relations teams at the University of Namur and the University of Sfax for their help in setting up and monitoring the ERASMUS+ project.

FNRS 2024 calls: Focus on the NISM Institute

Sciences
Chemistry

Several researchers at the Namur Institute of Structured Matter (NISM) have recently been awarded funding from the F.R.S - FNRS following calls whose results were published in December 2024. The NISM Institute federates the research activities of the chemistry and physics departments of the University of Namur.

Luca Fusaro: "Crystallization of complex phases in confined space

The aim of this FNRS-funded research project (PDR) is to deepen knowledge of the complex crystalline phases of simple salts. The project aims to strengthen international research activities, which began in 2016 and led to the publication of the first results in Nature in 2021. Read the article online...

In this study, the researchers had isolated four different crystalline phases from a salt of Fampridine, an organic compound used to treat the symptoms of multiple sclerosis. Two crystalline phases showed remarkable complexity, belonging to the special class of Frank and Kasper (FK) phases.

Des cristaux de la Fampridine hydrochlorate ayant une phase complexe de type FK.
Fampridine hydrochlorate crystals with an FK complex phase.

FK phases have been known since 1959 as a large family of metal alloys, but the study demonstrated that simple pharmaceutical molecules can crystallize with similar complexity, something not previously known.

With this new project, the researchers aim to go one step further, using mainly solid-state nuclear magnetic resonance (NMR) and X-ray diffraction (XRD) techniques on powders and single crystals. This study will be carried out in collaboration with other researchers at the NISM Institute (Nikolay Tumanov, Carmela Aprile and Johan Wouters), as well as collaborators working in other countries, such as Riccardo Montis (University of Urbino, Italy) and Simon Coles (Director of the National Crystallography Service (NCS), University of Southampton, UK).

Stéphane Vincent (with UCLouvain): "NPN cofactor synthesis and roles".

The research project (PDR) "NPN cofactor synthesis and roles" is at the interface between fundamental biochemistry and enzymology. It is based on the recent discovery, by a team at UCLouvain, of a new cofactor, named NPN, with a highly original structure. It is a dinucleotide bearing a nickel complex. It is involved in important enzymatic reactions, but little is known about its reactivity, biosynthesis and mechanism of action. Moreover, it is present in 20% of bacterial genomes and 50% of Archaea (archaeobacteria) genomes, but only a tiny fraction of the enzymes employing it have been characterized.

The research project is based on the complementary expertise of Benoit Desguin (UCLouvain, biochemistry) and Stéphane Vincent (bio-organic chemistry). The main aim of the project is to understand the role and mechanism of this cofactor through biochemical, structural and kinetic studies. Analogues of the NPN cofactor will be synthesized by the UNamur team: they will be designed to elucidate the mode of interaction and reaction of the NPN cofactor with the enzymes employing it.

Johan Wouters (with UCLouvain): "Crystallization-based deracémisation in the era of green chemistry".

This research project (PDR) is a co-promotion of Professors Tom Leyssens (UCLouvain) and Johan Wouters (UNamur). It aims to bring the process of uprooting by crystallization into the era of "green chemistry".

Uprooting is a term used in chemistry to describe the process of separating a racemic mixture into its two enantiomers, i.e. the chiral (left and right) forms of a molecule. In the pharmaceutical industry, 50% of marketed drug compounds contain a chiral center, which is essential to their functioning. When one enantiomer has the desired pharmacological effect, the other may be inactive or have undesirable effects. For this reason, new drugs are often marketed as enantiopure compounds (i.e. free of their impure "chiral twin").

The most common way of obtaining chiral drugs still involves the formation of a racemic mixture. This can then be produced by chemical or physical separation techniques, with a yield loss of 50%. If the compound in question is "racemizable", the unwanted enantiomer can technically be converted back into a racemic mixture, resulting in a theoretical yield of 100%. Over the past decade, various crystallization-based uprooting methodologies have been developed. However, all these methods require the use of large quantities of solvent, as they are crystallization processes.

This research aims to take these processes to the next level, not only by making them more efficient (less time-consuming), but also by bringing them into the realm of "green chemistry". To this end, the researchers are proposing mechanochemical variants for conglomerates and racemic compounds.

These processes will be

  • Inherently "green", since the unwanted enantiomer is transformed into the desired enantiomer;
  • Enabled by mechanochemistry, which eliminates the need for solvent, making them "greener" than solution-based methods.
  • The "greenest" possible, thanks to their efficiency (very fast timescale and low energy consumption).

Catherine Michaux, Stéphane Vincent and Guillaume Berionni were awarded equipment financing (EQP).

This funding will enable the acquisition of high-throughput isothermal titration calorimetry (ITC) equipment, unique in the Wallonia-Brussels Federation. This is a high-resolution, non-destructive method enabling complete characterization of the chemical details of an interaction in solution.

His acquisition will enable UNamur chemists, but also their collaborators, to analyze any bond, in a vast field of application, extending from biochemistry to supramolecular chemistry.

"ONL molecular switches "in all their states": from solutions to functionalized surfaces and solids."

This PhD thesis within the Theoretical Chemistry Laboratory (Department of Chemistry) and the Multiscale Modeling through High-Performance Computing (HPC-MM) Cluster of the NISM Institute aims to develop innovative multiscale computational methodologies to study and optimize multistate and multifunctional molecular switches, key components of logic devices and new generations of data storage technologies.

In addition to variations in linear optical responses, it is advantageous to consider changes in nonlinear optical responses (NLOs), which enable high-resolution data readout while avoiding their destruction. The main objective is to predict and interpret the ONL responses of these molecular switches in different matter environments, namely in solution, grafted onto surfaces and in the solid state.

In addition, particular attention will be paid to modeling defects and orientational disorder within materials to better represent real-world conditions. These predictive methods will be validated experimentally through close collaborations with synthesis and characterization teams.
