SPiN: a new research center for a new way of thinking about science
At a time when misinformation, post-truths and conspiracies are undermining confidence in science, UNamur welcomes SPiN (Science & Philosophy in Namur), a new interdisciplinary research center that questions the place of science in society. Founded last September by Olivier Sartenaer, Professor of Philosophy of Science at UNamur, SPiN brings together philosophers and scientists around a common vision: to develop a critical and accessible reflection on science in all its diversity..

The importance of languages in university studies
Why take English classes when you want to become a veterinarian? How can you teach Spanish to future management engineers? Far from vocabulary lists or lab classes with headphones, these languages are taught as genuine cross-disciplinary skills that are essential for the jobs of tomorrow.

CHITEL 2024 - Congress of Theoretical Chemists of Latin Expression
Initiated in 1969 by Pullmann and Del Re, the congress is an annual meeting to promote collaboration and friendship between Latin-speaking theoretical chemists. In its early years, European researchers were the main contributors. Subsequently, the Latin American community has made a major contribution, with the emergence of teams whose international reputation now extends far beyond our own community.We are delighted to be holding this meeting at the University of Namur, 55 years after the first CHITEL was organised in Paris, France. We are sure that this 2024 edition will once again be an opportunity to take advantage of the good humour and dynamism of Latin to encourage, develop and strengthen scientific exchanges.We look forward to welcoming you at the University of Namur,The CHITEL 2024 Local Organising Committee.

Chill&Sciences | From viruses to space, it's mathematical!
On Thursday May 30, for our last Chill&Sciences of the season, Candy Sonvaux and Alexis Coyette, mathematics researchers, invite you to discover the mathematics where the movements of the planets and the spread of viruses intertwine until they impact our society.Chill&Science: enriching encountersWith nearly 20 years' experience of scientific cafés, the Confluent des Savoirs has set up a new concept of scientific encounters. The Chill&Sciences are a unique opportunity for the public to come and discuss and ask questions of experts on research topics related to current affairs and citizen issues.Come and enjoy the unique, relaxed atmosphere of Quai22. Researchers and experts from the seven faculties of the University of Namur will present their research and discuss with you over a drink (or two, but never without exaggeration).In practiceThe meetings are open to everyone aged 16 and over. Evenings are limited to around 20 people to ensure a relaxed atmosphere and to facilitate discussions. Meetings take place if a minimum of 10 people are registered. Except in exceptional circumstances, meetings take place every 2 months at the University of Namur's cultural space, Quai22, located at n°22 Rue du Séminaire.Tarif Participation in a Chill&Sciences costs 5€. A discounted annual pass is available. Please note: preferential rate for students (discount code: PromoCDS).The booking fee includes a drink* (soft or beer), a snack (chips and cookies) and management fees linked to the organization Unless cancelled by us, bookings are non-refundable. (*additional drinks will be available upon electronic payment.)

Title of the dissertation: Ion implantation in Low-E coatings
Low-emissivity (Low-E) coating technology revolutionizes glass applications for windows, offering high optical transparency while reducing heat transfer. They consist of a silver-based thin film deposited on a glass panel by physical vapor deposition. However, these coatings are fragile and must be placed inside a double-glazing cavity where an inert gas resides. Otherwise, they can be easily degraded by bad atmospheric conditions.The thesis approach is to combine low-E technology with a post-treatment of ion implantation. The research question driving this thesis is: how does ion implantation enhance the durability of low-E coatings containing silver?The experiments conducted during the thesis show that implantation indeed increases the coating resistance while having a small impact on its color. However, the treatment degrades the thermal insulation properties. Hence, a series of hypotheses are formulated based on the literature to explain and control this behavior.A deeper investigation shows that implantation impacts the silver nanostructure. First by dewetting the film which allows reorganization into larger crystallites, second by forcing silver mixing at its interface through ballistic ejections. These two phenomena increase the toughness of the silver interface by interlocking effects. However, dewetting has also been linked to thermal insulation properties degradation. Nonetheless, it was shown that using light gas implantation limits the destructive effect (dewetting) while still inducing good durability (due to interface mixing)..

Characterization of trehalase from Acyrthosiphon pisum for the design of new insecticides
SummaryAphids are major pests in agriculture, causing direct damage to plants and acting as vectors for phytopathogenic viruses. Conventional insecticides are widely used to control them, but their toxicity and efficacy pose problems in terms of the environment, human health and the emergence of resistance to these compounds. New alternatives are therefore needed, such as biological control using predators or parasitoids. However, these methods are not always economically viable on a large scale. As part of this thesis, another approach is being explored which involves developing new insecticides targeting the biochemical functions of aphids.The project aims to discover new inhibitors of trehalase, an enzyme essential for insect energy metabolism. Inhibition of this enzyme could disrupt vital insect functions without affecting mammals. This research involved several stages: the purification and complete characterization of trehalase from Acyrthosiphon pisum (the model for this study), the in vivo, in vitro and in silico analysis of commercial inhibitors on this enzyme, before moving on to the search for new inhibitors. Two points of integrated insect management were explored, biological and chemical control.The biological side saw the study of a strain of Streptomyces naturally producing trehalase-inhibiting metabolites, notably validamycin A, a molecule recognized in the literature as one of the best inhibitors, but not applicable as an insecticide. Other molecules appear to have interesting features, but we have not been able to isolate and characterize them.The chemical side has enabled us to create a pharmacophore hypothesis based on experimental results on molecules obtained by virtual screening. Although these molecules are not usable as insecticides as they stand, this hypothesis provides a better understanding of trehalase inhibitors in general and can be used to refine future analyses.
