They are supported by a technology park of advanced experimental techniques for studying the chemical and physical properties of these systems at micro- and nanometric scales. The research carried out within the institute falls within the field of both fundamental research, aimed at understanding and predicting the properties of structured matter, and applied research, with the aim of developing functional materials and devices.

NISM's lines of research are currently grouped into four poles, whose perimeters are flexible, reflecting the transdisciplinarity of the research themes and the collaborative dynamic between poles.

Each cluster is represented by a permanent scientist and a non-permanent scientist who, together with the institute's president and vice-president, form the institute's executive committee.

The institute's executive committee is made up of the president and vice-president of the institute.

NISM research poles

Research at NISM is identified by four poles which highlight the main scientific activities carried out within the institute. Each pole is a well-defined structure with members, and is managed by the pole representative. The structuring of the pole does not prevent ongoing cooperation between them. Indeed, there is well-established interaction between the various poles, through joint projects, conferences, seminars, co-supervision of master's and doctoral theses, among others.

CERN

CERN, the European Organization for Nuclear Research, is one of the world's largest and most prestigious scientific laboratories. Its vocation is fundamental physics, the discovery of the constituents and laws of the Universe. It uses highly complex scientific instruments to probe the ultimate constituents of matter: the fundamental particles. By studying what happens when these particles collide, physicists understand the laws of Nature.

The instruments used at CERN are particle gas pedals and detectors. Gas pedals carry beams of particles at high energies to collide with other beams or fixed targets. Detectors observe and record the results of these collisions.

Founded in 1954, CERN is located on either side of the French-Swiss border, near Geneva. It was one of the first organizations on a European scale and today has 25 member states, including Belgium.

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.

The "chemists" who specialize in the reactivity of matter cultivate the art of experimentation and discovery. The products of their essential knowledge are applied in the fields of nutrition, health, hygiene, transport, sport, construction and environmental protection.

Towards highly energy-efficient smart windows?

Physics
Sustainable
Materials, energy and environment

Researchers at ULiège and UNamur are developing a new electrochromic material: MoWOx.

Chercheur qui regarde à travers une vitre
  • This research, still at the experimental stage, is based on a new formulation of electrochromic material: MoWOx, a mixed molybdenum-tungsten oxide
  • This advance makes it possible to envisage "dual-band" functionality, i.e. selective and independent modulation of incoming light and heat flows
  • The results have been published in the journals Advanced Optical Materials and ACS Applied Optical Materials

Scientists from the University of Liège (ULiège) and the University of Namur (UNamur) have developed an innovative electrochromic material capable of independently regulating light and heat in buildings. This breakthrough, based on a mixed molybdenum-tungsten oxide (MoWOx), paves the way for even more efficient and energy-saving smart windows.

Electrochromic windows are smart glazings capable of modulating their coloration, or more generally their state of transparency or opacity, when an external electric current is applied to it. This property makes it possible to control the intensity of solar radiation entering a building, without the need for blinds or curtains. This type of window is already manufactured industrially and used technologically in some buildings, but current products do not allow separate control of visible light (VIS) and near-infrared radiation (NIR), respectively linked to incident brightness and heat.

Researchers at ULiège and UNamur, thanks to support from the Fonds de la Recherche Scientifique (FNRS), have thus developed a new formulation of electrochromic material, entitled MoWOx, based on a "dual-band" functionality enabling selective and independent modulation of incoming light and heat fluxes.

Through this new formulation, the scientific teams have demonstrated the occurrence of an innovative optical mode, known as "warm", for the first time for this type of oxide. In this mode, the glass remains transparent to infrared radiation, allowing heat to pass through, while only partially filtering out visible light. This feature is particularly interesting for cold climates and winter periods, where maximizing solar heat gain while reducing solar glare can significantly reduce building energy consumption, particularly in terms of heating and artificial lighting.

.

A plasmonic nanomaterial for advanced optical filtration

This "dual-band" functionality is based on the incorporation of nanostructured plasmonic compounds into the smart glass. A plasmonic material is one whose free electrons can oscillate collectively under the effect of light. It can then selectively absorb, reflect or scatter light, depending on its composition and structure. And it is precisely in the application of these plasmonic properties of MoWOx to the case of smart glazing that this innovation lies.

On this basis, the composition and morphology of plasmonic nanostructures directly influence the optical selectivity of filtering, enabling glazing to be tailored more precisely to users' needs.

.

A promising application for the buildings of the future

Future intelligent glazing incorporating these new components could ultimately revolutionize energy management in buildings. In a context where the energy transition remains a top priority, these innovative windows will help to achieve carbon neutrality targets and build near-zero energy buildings.

Florian Gillissen, researcher at the University of Liège and first author of the paper published in Advanced Optical Materials:"Thanks to this technology, we can adjust the transmission of light and heat through windows in real time, which represents a giant step forward for the energy optimization of buildings."

Professor Michaël Lobet, FNRS Qualified Researcher and first author of the paper published in ACS Applied Optical Materials: "Theoretical and numerical modeling was carried out at UNamur in Professor Luc Henrard's team, while material synthesis and characterization was carried out under the direction of Professor Rudi Cloots and Dr. Anthony Maho from the University of Liège. It is these synergies between theoretical modeling and fabrication that have enabled the characterization of these MoWOx materials."

FNRS 2024 calls: Focus on the NISM Institute

Sciences

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.

CERN

CERN, the European Organization for Nuclear Research, is one of the world's largest and most prestigious scientific laboratories. Its vocation is fundamental physics, the discovery of the constituents and laws of the Universe. It uses highly complex scientific instruments to probe the ultimate constituents of matter: the fundamental particles. By studying what happens when these particles collide, physicists understand the laws of Nature.

The instruments used at CERN are particle gas pedals and detectors. Gas pedals carry beams of particles at high energies to collide with other beams or fixed targets. Detectors observe and record the results of these collisions.

Founded in 1954, CERN is located on either side of the French-Swiss border, near Geneva. It was one of the first organizations on a European scale and today has 25 member states, including Belgium.

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.

Towards highly energy-efficient smart windows?

Physics
Sustainable
Materials, energy and environment

Researchers at ULiège and UNamur are developing a new electrochromic material: MoWOx.

Chercheur qui regarde à travers une vitre
  • This research, still at the experimental stage, is based on a new formulation of electrochromic material: MoWOx, a mixed molybdenum-tungsten oxide
  • This advance makes it possible to envisage "dual-band" functionality, i.e. selective and independent modulation of incoming light and heat flows
  • The results have been published in the journals Advanced Optical Materials and ACS Applied Optical Materials

Scientists from the University of Liège (ULiège) and the University of Namur (UNamur) have developed an innovative electrochromic material capable of independently regulating light and heat in buildings. This breakthrough, based on a mixed molybdenum-tungsten oxide (MoWOx), paves the way for even more efficient and energy-saving smart windows.

Electrochromic windows are smart glazings capable of modulating their coloration, or more generally their state of transparency or opacity, when an external electric current is applied to it. This property makes it possible to control the intensity of solar radiation entering a building, without the need for blinds or curtains. This type of window is already manufactured industrially and used technologically in some buildings, but current products do not allow separate control of visible light (VIS) and near-infrared radiation (NIR), respectively linked to incident brightness and heat.

Researchers at ULiège and UNamur, thanks to support from the Fonds de la Recherche Scientifique (FNRS), have thus developed a new formulation of electrochromic material, entitled MoWOx, based on a "dual-band" functionality enabling selective and independent modulation of incoming light and heat fluxes.

Through this new formulation, the scientific teams have demonstrated the occurrence of an innovative optical mode, known as "warm", for the first time for this type of oxide. In this mode, the glass remains transparent to infrared radiation, allowing heat to pass through, while only partially filtering out visible light. This feature is particularly interesting for cold climates and winter periods, where maximizing solar heat gain while reducing solar glare can significantly reduce building energy consumption, particularly in terms of heating and artificial lighting.

.

A plasmonic nanomaterial for advanced optical filtration

This "dual-band" functionality is based on the incorporation of nanostructured plasmonic compounds into the smart glass. A plasmonic material is one whose free electrons can oscillate collectively under the effect of light. It can then selectively absorb, reflect or scatter light, depending on its composition and structure. And it is precisely in the application of these plasmonic properties of MoWOx to the case of smart glazing that this innovation lies.

On this basis, the composition and morphology of plasmonic nanostructures directly influence the optical selectivity of filtering, enabling glazing to be tailored more precisely to users' needs.

.

A promising application for the buildings of the future

Future intelligent glazing incorporating these new components could ultimately revolutionize energy management in buildings. In a context where the energy transition remains a top priority, these innovative windows will help to achieve carbon neutrality targets and build near-zero energy buildings.

Florian Gillissen, researcher at the University of Liège and first author of the paper published in Advanced Optical Materials:"Thanks to this technology, we can adjust the transmission of light and heat through windows in real time, which represents a giant step forward for the energy optimization of buildings."

Professor Michaël Lobet, FNRS Qualified Researcher and first author of the paper published in ACS Applied Optical Materials: "Theoretical and numerical modeling was carried out at UNamur in Professor Luc Henrard's team, while material synthesis and characterization was carried out under the direction of Professor Rudi Cloots and Dr. Anthony Maho from the University of Liège. It is these synergies between theoretical modeling and fabrication that have enabled the characterization of these MoWOx materials."

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.

Abstract

Radiotherapy is a cornerstone of cancer treatment and is currently administered to approximately half of all cancer patients. However, the cytotoxic effects of ionizing radiation on normal tissues represent a major limitation, as they restrict the dose that can be safely delivered to patients and, consequently, reduce the likelihood of effective tumor control. In this context, delivering radiation at ultra-high dose rates (UHDR, > 40 Gy/s) is gaining increasing attention due to its potential to spare healthy tissues surrounding the tumor and to prevent radiation-induced side effects, as compared to conventional dose rates (CONV, on the order of Gy/min).

The mechanism underlying this protective effect-termed the FLASH effect-remains elusive, driving intensive research to elucidate the biological processes triggered by this type of irradiation.

In vitro models offer a valuable tool to support this research, allowing for the efficient screening of various beam parameters and biological responses in a time- and cost-effective manner. In this study, multicellular tumor spheroids and normal cells were exposed to proton irradiation at UHDR to evaluate its efficacy in controlling tumor growth and its cytotoxic impact on healthy tissues, respectively.

We report that UHDR and CONV irradiation induced a comparable growth delay in 3D tumor spheroids, suggesting similar efficacy in tumor control. In normal cells, both dose rates induced similar levels of senescence; however, UHDR irradiation led to lower apoptosis induction at clinically relevant doses and early time points post-irradiation.

Taken together, these findings further highlight the potential of UHDR irradiation to modulate the response of normal tissues while maintaining comparable tumor control.
