What is a perfect fluid? It is a theoretical model of a fluid that allows us to assume that the fluid is not viscous, that it does not conduct heat, that it is incompressible and does not create vortices. It is therefore an approximation of reality that simplifies theoretical predictions of fluid flows. For the first time, an international team has experimentally demonstrated this same behaviour for light immersed in a medium of low refractive index.

The two UNamur professors were appointed for a four-year term. The academic members of the Central Economic Council (CEC) are chosen in order to inform the debates of the social partners (employers and trade unions) present at the council with their expertise.

In January 2023, an international symposium on organic chemistry was held at UNamur in honour of the 80th birthday of Professor Emeritus Alain Krief. A scientific day with six renowned speakers, including Professor Jean-Marie Lehn, 1987 Nobel Prize in Chemistry. Interview.

On 21 and 22 September 2023, for the 4th year running, Belgian researchers came together for the bePOM conference. The format was original, with a virtual day and a hybrid day combining virtual and face-to-face sessions. A great success, and a Belgian network that is growing from strength to strength.

The absorption of light by molecules has applications in microscopy, medicine and data storage. With this research, the researcher from the UNamur NISM institute fills an experimental gap, which will enable molecular engineers to develop new and more efficient compounds in their various fields of application.

Yves Caudano, F.R.S.-FNRS qualified researcher, member of the NaXys and NISM Institutes and the UR-LLS (Lasers and Spectroscopies Laboratory) research unit, is taking part in a major European research project. The aim? To find new quantum light sources with unprecedented versatility, flexibility and performance.

An international group of researchers, including Professor Yoann Olivier from the NISM Institute at UNamur, has just published in the prestigious journal Nature. The subject: understanding the microscopic mechanisms that lead to the initialisation, reading and erasing of molecular qubits, a new theme in the study of materials, at the frontier between physics and chemistry.

Dr. Sébastien Mouchet, a researcher at UNamur and member of the NISM and ILEE Institutes, has just published the results of research focusing on the effects of pollution on coral reef fish in MDPI-Optics. The findings of the international, multidisciplinary team lead to crucial conclusions with implications for the health of marine ecosystems.

Within the SPACE pole of the naXys Institute, researchers are interested in the evolution of planetary systems at different scales: space debris, natural and artificial satellites, asteroids, (exo)planets, etc. As part of the JUICE mission, post-doctoral researcher Alexis Coyette and Professor Anne-Sophie Libert are interested in Ganymede, one of Jupiter's moons, and are seeking to model its internal composition and rotation. It is believed that this satellite has a global ocean of liquid water beneath its surface. The study of its rotation will provide more information about this ocean and thus the potential habitability of this satellite.

On 9 June 2023, the NISM and naXys Institutes, the Physics and Chemistry Departments and the Namur Research College were delighted to welcome Prof. Jean-Luc Brédas from the University of Arizona. A prestigious speaker of international renown, Prof. Brédas completed his doctoral thesis with Prof. Jean-Marie André at the University of Namur.

Very often in nature, we observe phenomena of natural synchronisation and the emergence of regular patterns: a crowd applauding in unison at the end of a concert, the cells in the walls of the heart pulsating in a coordinated fashion, black and white stripes on a zebra, brown spots surrounded by black in leopards... But how can we explain this uniformity if there is no global controller or explicit rule directing this coordination?

BepiColombo will fly past Mercury on 19 June 2023. It will pass close to the planet's surface at an altitude of approximately 236 km. BepiColombo is an ESA/JAXA mission involving a team of researchers from the University of Namur (naXys institute).
