This doctoral study assesses pathways to enhance coastal sustainability in the Anthropocene, by promoting the sustainable use of mangroves and strengthening their social-ecological resilience through an interdisciplinary approach. The thesis is structured into four specific objectives: assessing the role of traditional beliefs and local deities in promoting the sustainable use of mangroves, analyzing the synergies between legal frameworks and traditional beliefs in enhancing the social-ecological resilience of mangroves, developing a novel interdisciplinary framework to evaluate the social-ecological resilience of mangroves, and operationalizing the proposed framework in Benin's mangroves, West Africa.  We collected field data using ethnobiological surveys, drone image analysis and document review, in-depth interviews, focus group discussions, plant and fish inventories across three coastal communities in Benin. The study draws insights from the seven principles of resilience to analyze mangrove sustainability. The interdisciplinary methodology of this study links plant biology, fisheries sciences, and human geography to analyze mangroves as complex social-ecological systems. Findings of the thesis show that traditional beliefs and local deities play a significant role in regulating the use of mangrove resources, while the overlapping of formal and informal institutions offer opportunities to enhance their social-ecological resilience. The novel proposed framework called Mangrove Social Ecological Resilience Appraisal (MaSERA) outlines variables and indicators tailored to mangroves to assess their social-ecological resilience. Its application in Benin highlights its potential in identifying factors that enable or erode mangrove resilience, for informed decision making. The study argues that promoting the sustainable use of mangroves and enhancing their social-ecological resilience represent dual imperatives for achieving coastal sustainability in the Anthropocene. It contributes to the growing body of knowledge on mangrove conservation and provides actionable insights for integrated coastal zone management.

For its inaugural conference, the SPiN (Science & Philosophy in Namur) center will be joined by Claire Rommelaere, a lawyer and researcher at the Center for Bioethics at the University of Namur, and Aude Bandini, a philosopher of science at the University of Montreal, to take a critical look at the theme of "distrust of science." The urgency of addressing this issue is clear in our era, where, despite an overall stable level of trust in science, the parameters of public debate are frequently blurred by misinformation.Having had the opportunity to observe philosophers of science in their natural habitat for nearly fifteen years, Claire Rommelaere will share her thoughts on whether or not we should trust those who think about science.For her part, Aude Bandini will address a major problem that we all face at a time when the mass of available knowledge is such that it is impossible to acquire it on our own. Indeed, the socially distributed nature of knowledge generally leaves us no choice but to rely on the authority of experts, even on very important issues (such as health). However, when we rely on others in this way and follow recommendations that, due to our ignorance, we have no means of evaluating, we place ourselves in a relationship of "epistemic dependence" that conflicts with our aspirations for intellectual autonomy and forces us to ask ourselves a question whose answer may prove unbearable: is intellectual autonomy nothing more than a myth?Conference hosted by journalist Maïté Warland.Program:5:30-6:30 p.m. | Drinks at Quai 22 (Rue du Séminaire 22, 5000 Namur)6:30 p.m. | Claire RommelaereDistrust of philosophers of science7:00 p.m. | Aude Bandini Intellectualautonomy in the face of scientific authority: a headache for social epistemologyRegistration deadline: April 16.Free of charge.

A plant does not seem to have much in common with animals. Yet naturalists of the eighteenth and nineteenth centuries attempted to study plants as if they were animals: they set out, for example, to find an equivalent to the circulatory or respiratory systems. Why did they feel the need to resort to analogical reasoning? What results did they obtain? And more generally, what is the value of this type of reasoning?On the agendaTuesday, May 5, 202612:15 PM – Welcome and light lunch1:30 PM – Introductory remarksThibault De Meyer (University of Namur): Why Analogy?2:15 PM – Session 1: Theory and Practice - Cristiana Oghina-Pavie (University of Angers): The analogy of pragmatic knowledge: actions and transactions in 19th-century horticulture and Quentin Hiernaux (FNRS / Free University of Brussels): The plant-animal analogy employed by A.-P. de Candolle’s physiology in addressing the issue of the sensitivity of living beings3:45 PM – Coffee break4:15 PM – Plenary Session 1 - Thierry Hoquet (University of Paris Nanterre): Is the plant/animal analogy valid?5:45 PM – End of the first day7:00 PM – Conference dinnerWednesday, May 6, 20269:00 AM – Welcome9:15 AM – Session 2: Relationships and Boundaries of the Living - Dario Galvão (University of Namur): Analogy and the Faculties of the Living: Animal Reason and Plant Sensibility in the Enlightenment and Ugo Batini (University of Poitiers): Understanding Humanity Through Plants: Analogy and the Metaphysics of the Living in Schopenhauer10:45 AM – Coffee break11:15 AM – Plenary Lecture 2 – Pascal Duris (University of Bordeaux): Plants as Humans.

Abstract Wood combustion has historically provided essential heat and remains a crucial renewable energy source today. However, residential batch combustion inherently emits significant pollutants, including CO, VOCs, and PM. Since primary optimization measures cannot completely eliminate these emissions, secondary post-combustion remediation is necessary.To address this, the University of Namur and Stûv collaborated to evaluate the integration of a monolithic oxidation catalyst into an 8 kW residential wood stove.The initial study demonstrated exceptional abatement, reducing CO by 87%, PM by 66%, and highly toxic PAHs by over 90%. Crucially, in vitro assays on human lung cells proved that this chemical reduction directly translates to a 50% decrease in overall emission cytotoxicity.Subsequent mechanistic investigations using advanced speciation (PTR-TOF-MS) mapped the partial oxidation of non-methane VOCs. This revealed that the catalyst’s overall conversion efficiency is primarily limited by mass transfer rather than chemical kinetics.Finally, to overcome the inherent variability of batch combustion, a precise simultaneous direct-comparison methodology was developed. This novel approach confirmed the overall study’s findings, providing a robust and accurate framework for evaluating residential abatement technologies.

Ethics is practiced in hospitals. But ethics is also practiced in care and support facilities for the elderly and people with disabilities, as well as in pharmaceutical companies, research centers, and universities.We “practice ethics” in groups whose scope may be local, regional, national, continental, or international. We “practice ethics” by organizing conferences, conventions, meetings, roundtables, workshops, symposia, think tanks, and so on.But what exactly “do we do” in these settings? Is there really anything in common among all these groups, these settings, these collectives? It is not desirable to strive for a single model that would ignore the specific characteristics of the environments in which this activity takes place.But it is interesting and undoubtedly necessary to seek to better understand and define what each group does in this regard.

Since the early 2000s, it has become clear that combining robust intermolecular interactions with flexible linkers and deformable nodes can stabilize porous crystals during guest removal. Frameworks such as MOFs, COFs, and HOFs benefit from strong noncovalent interactions, yet permanently porous HOFs remain uncommon due to dense molecular packing.Porous organic salts (POSs) offer an alternative strategy, assembling predictable networks from oppositely charged organic ions where electroneutrality and stoichiometry guide structure formation. However, most 3D POSs rely on planar guanidinium or tetrahedral tetraphenylmethane derivatives, resulting in a narrow set of topologies compared with the thousands of 3D nets catalogued in the Reticular Chemistry Structure Resource (RCSR).Here we report triptycene-based ionic frameworks (TIFs) formed via charge-assisted ammonium-sulfonate hydrogen bonding. By tuning triptycene symmetry and functionalization, together with sulfonate linker geometry, we generated diverse supramolecular architectures with tailored porosity, stability, and function.

Decarboxylation has become a key chemical transformation and has been widely reported in organic chemistry except for carbohydrates. This reaction can be catalyzed by transition metal and can also be induced by light, thermal activation, or photocatalysis. Borylated compounds have stimulated the pharmaceutical industry's interest (Boromycin, Bortezomib or boron neutron capture therapy). Recent methodologies have been developed to transform carboxylic acids to boronate esters by metal-catalyzed or light-promoted or photocatalyzed reactions. In this thesis, we explored the synthesis of borylated carbohydrates through a decarboxylation pathway. More specifically, sialic acids being among the most important carbohydrates in glycobiology, we addressed the problem of the synthesis of borylated sialic acids. On the other hand, organophosphates play an important role in diverse fields: in materials chemistry, in agriculture, in organic chemistry, and in biochemistry. Phosphorylation is a key reaction in biological processes such as signal transduction and cell activity regulation. The formation of phosphorylated carbohydrates has been widely described through two-electron mechanisms. However, radical phosphorylation of carbohydrates remains unexplored. This Ph.D. thesis describes the development of new methodologies for the decarboxylative functionalization of carbohydrates, focusing on borylation and phosphorylation..

AbstractIn CO2-rich atmospheres such as that of Venus, the study of water vapor requires the use of H2O collision parameters for CO2. However, due to a lack of data, models still use collision parameters for air to estimate the abundance of water vapor in this type of atmosphere. In this thesis, new experimental laboratory measurements of the collision parameters of H2O, HDO, and D2O by CO2 were carried out. These were then used as the basis for dedicated theoretical calculations. Their impact was evaluated using radiative transfer simulations applied to the atmosphere of Venus, under conditions close to those of future observations by the European EnVision mission. The results clearly show that using collision parameters for air instead of CO2 can lead to an overestimation of nearly 40% of the abundance of water vapor in the mesosphere and to inversion difficulties in the troposphere. This work thus provides essential elements for improving the spectral analysis of CO2-rich atmospheres.JuryDr. Ha TRAN (Sorbonne University), ChairProf. Muriel LEPÈRE (University of Namur), SecretaryDr. Emmanuel MARCQ (University of Versailles)Dr. David JACQUEMART (Sorbonne University)Dr. Laurence RÉGALIA (University of Reims)Dr. Séverine ROBERT (Royal Institute for Space Aeronomy, Belgium)

AbstractNosocomial infections are a major public health problem, exacerbated by the global spread of bacterial resistance to antibiotics. Faced with this challenge, it is crucial to explore alternatives or complementary strategies to conventional treatments. Among these, the use of copper is attracting renewed interest. This metal has natural antibacterial properties that have been recognized since ancient times. It acts through multiple mechanisms such as membrane alteration, the generation of reactive oxygen species, and the denaturation of proteins and nucleic acids, leading to rapid cell death. These characteristics make it an effective biocidal agent in many contexts, particularly in hospitals.However, the selective pressure exerted by the increased presence of copper in the environment has led to the emergence of specific resistance systems in certain bacteria. These systems allow strict control of copper homeostasis by limiting its intracellular accumulation through efflux, sequestration, or oxidation mechanisms. In Caulobacter crescentus, an environmental bacterial model, copper resistance is based in particular on the Pco system. This system is composed of the PcoB protein, located in the outer membrane. Although its structure has been partially described in E. coli, its precise function remains unclear. Preliminary observations suggest that it may be involved in the export of copper from the periplasm to the outside of the cell, thus acting as a release pathway.To explore the role of PcoB in bacterial copper resistance, this study focused on the structural and functional characterization of the protein. After extraction and purification, PcoB was incorporated into artificial liposomes to develop an in vitro transport assay to assess its ability to release copper across a lipid bilayer. At the same time, a truncated mutant lacking the disordered N-terminal region was produced and subjected to the same analyses. The comparison between the complete and truncated forms aims to determine the involvement of this flexible region in the transport mechanism and stability of the protein. These approaches have laid the initial experimental foundations for studying the transport mechanism of PcoB and constitute a first step towards a detailed understanding of how the Pco system works. They also open up prospects for the development of new antibacterial strategies targeting copper management systems in bacteria.JuryProf. Johan WOUTERS (UNamur), ChairDr. Catherine MICHAUX (UNamur), SecretaryProf. Jean-Yves MATROULE (UNamur)Dr. Guillaume ROUSSEL (UCLouvain)Prof. Francesca CECCHET (UNamur)Prof. Hennie VALKENIER (ULB)
