The university has a duty to set an example in terms of sustainable development, in all three of its dimensions: economic, social and environmental. Sustainable "in form" through the way it manages its infrastructures and assets, and sustainable "in substance" through its commitment to research and teaching activities, in order to actively contribute to the environmental transition. All in line with the United Nations' Sustainable Development Goals (SDGs).

Founded some 50 years ago, the Laboratoire d'Analyse par Réactions Nucléaires (LARN) in the Department of Physics at the University of Namur is home to a 2MV tandem particle gas pedal named ALTAÏS (Accélérateur Linéaire Tandetron pour l'Analyse et l'Implantation des Solides), in operation since 1999.

High-Sensitivity Birefringence Mapping Using Near-Circularly Polarized Light I will describe several techniques for mapping a two-dimensional birefringence distribution, which can be classified according to the optical schemes and principles of work:Illumination geometry (transmitted light/reflected light)Image acquisition (sequential acquisition/simultaneous acquisition)Polarization control (electrically controlled variable retardance/mechanical rotation).This classification facilitates a comparative analysis of the capabilities and limitations in these methods for birefringence characterization. Polychromatic polarizing microscopy (PPM) provides unique capabilities to alternative methods. It leverages vector interference to generate vivid, full-spectrum colors at extremely low retardances, down to < 10 nm. PPM is a significant departure from conventional polarizing microscopes that rely on Newton interference, which requires retardances above 400 nm for color formation. Furthermore, PPM's color output directly reflects the orientation of the birefringent material, a feature absent in conventional microscopy where color is solely determined by retardance.Joint seminar of ILEE & NISM!The seminar is open to external people too, no need to register.

From 2020 to 2025, as part of her doctoral thesis in history, researcher Julie Duchêne conducted a ground-breaking investigation blending history and biology to trace the cohabitation between humans and wolves in Wallonia and Luxembourg, from the 18th to the early 20th century. Thanks to an innovative interdisciplinary approach, including DNA analysis of naturalized 19th-century specimens, her work sheds light on the mechanisms that led to the local extinction of the species. This research was made possible thanks to the support of numerous scientific and cultural partners.

The availability of natural resources for future generations can only be ensured through prudent use.

ILEE combines a broad range of basic, applied and social science skills that focus on three key areas of study, including historical perspectives and extensive partnerships with the global South.

For four billion years, life on earth has been evolving and transforming in response to environmental change, resulting in fluctuating biological diversity. Ecosystems provide humanity with a wide range of free services that must be managed responsibly.

Through a variety of chemical, biological and physical factors, humans are modifying ecosystems, often with negative results. Environmental changes, in turn, affect the dynamics of human populations.

ILEE collaborates with partners located in the countries of the South: Africa, Central and South America and Southeast Asia.

The Institute's research projects, publications, collaborations and network include all categories of researchers. Spearheaded by academic promoters, they mobilize post-doctoral researchers, PhD students and even master's students (student researchers).

Since arriving on Earth, man has begun to influence and modify his environment.
