Certains objets sont très difficiles à recycler parce qu'ils sont faits de nombreuses couches de différents matériaux : baskets, panneaux photovoltaïques ou batteries. Au laboratoire ICMCB à Bordeaux, une équipe de chercheurs utilise les fluides supercritiques pour séparer les éléments. C'est un domaine entre le solide et le gazeux où les propriétés des matériaux sont étonnantes et promettent de belles avancées dans le recyclage des déchets...

Tiamat designs, develops, and produces sodium-ion batteries in a standard industrial format. These batteries could mitigate some of the limitations of the lithium-ion batteries that currently prevail, such as charging speed, lifespan, and the cost of production. Located in Amiens (northern France), this young company emerged from the French Research Network on Electrochemical Energy Storage (RS2E) led by the CNRS, and now has a few dozen functional prototypes available. Some of them, including…

In South-Western France, several research laboratories work on polymers and their possible applications in the biomedical sector. In fact, they help to design new types of drugs at the nanoscale. Researchers Etienne Duguet and Sébastien Lecommandoux discuss the different processing phases of this macromolecule. They discuss the manufacture of nanovectors, polymer capsules that can be injected into the human body to identify diseased tissues or organs without being detected by the immune…

For the first edition of the Cinémascience festival in Bordeaux a laboratory in Aquitaine is in the spotlight with Claude Delmas, as the director of the Institut de chimie de la matière condensée de Bordeaux (Bordeaux institute for condensed matter chemistry - ICMCB) presenting its activities. The ICMCB studies the properties of solid materials. Issues related to energy and the environment constitute one of its research lines. Jean-Claude Grenier works on fuel cells. Unlike conventional…

As chemical and sound pollution increases, the electric vehicle becomes a solution to urban transportation problems. In La Rochelle and Bordeaux, the city government has set an example. The idea comes in various forms - scooters, river boats, and delivery services. Industry and research organizations are actively involved. CNRS laboratories are carrying out research on battery components. The use of electric vehicles of many kinds is becoming widespread.
