Le centre des matériaux souhaite recruter un(e) jeune enseignant(e)-chercheur(e) en métallurgie physique, sur un poste permanent.
CLYM also opens its doors to schoolchildren for the Fête de la Science 2023.
On Monday October 9 and Tuesday October 10, classes from CP to Terminale will be welcomed at INSA de Lyon. Accompanied by their teachers, they will be able to discover the world of research and observe everyday objects, at scales previously inaccessible to them. The event is a great success, with a full schedule!
On Tuesday October 10, high school students will also be able to visit the microscopy facilities at the Hubert Curien laboratory in Saint-Etienne.
For the Fête de la Science 2023, CLYM opens its doors to the public. Demonstrations will be held on different types of microscopes used for research: electron microscopes, atomic force microscopes. You willll be able to discover the wonders hidden in your everyday life, with details ranging from the micrometer to the atom. A breathtaking journey for all ages!
Abiotic reactions, not caused by living beings, are a missing key to determine where life may have emerged. Key gases of a prebiotic environment (N2, H2, CH4, CH3SH) associated with polyaromatic carbonaceous materials and nanodiamonds have been identified within samples from the Atlantis massif located along the Mid-Atlantic Ridge.These varied ingredients remain trapped until they are remobilized at shallower depths, where they can participate in the formation of complex organic molecules.These results revive the theory of a hydrothermal origin for the emergence of life on Earth.
Since their formation, the Earth and the other planets or bodies of the solar system, such as the moon or Mars in particular (see the recent images of the surface of Mars taken by the Perseverance Supercam cameras), have been subjected to a continuous bombardment of solid bodies (asteroids) from space.
Scientists are trying to date (thanks to the U-Pb method) precisely the moments when asteroids have impacted the Earth. The idea is to link these impacts to possible environmental catastrophes that they would have initiated. To do this, we are looking for clues preserved in the rocks that were shocked during the impact on Earth. These clues are identifiable in the minerals on a very small scale (a few nanometers) and testify to the intense deformations that the material underwent during the impact.
