During peak pollution events, everyone is talking about them. Fine particles are often accused of being toxic. Unfortunately, they do not only come out during episodes of high pollution. Véronique Riffault, a researcher in atmospheric sciences at IMT Lille Douai, revisits the basics of fine particles to better understand what they are all about.   What does a fine particle …

Cellulose is one of the most abundant molecules in nature. At the nanoscale, its properties allow it to be used for promising applications in several fields. Julien Bras, a chemist at Grenoble INP, is working to further develop the use of this biomaterial. On November 21st he received the IMT-Académie des Sciences Young Scientist Prize at the official awards ceremony held in …

Following on from our series on the platforms provided by the Télécom & Société numérique Carnot institute, we will now look at VIGISAT, based near Brest. This collaborative hub is also a project focusing on the satellite monitoring of oceans and continents in high resolution.   On 12th July, scientists in Wales observed a drifting iceberg four times the size of …

The storage of green energy is an issue which concerns many sectors, whether for energy transition or for supplying power to connected objects using batteries. Thierry Djenizian, a researcher at Mines Saint-Étienne, explains the main problems to us, focusing in particular on how electrochemical storage systems work.   Why is the storage of renewable sources of energy (RSE) important today? …

The theme day on air quality modeling (organized by FIMEA and IMT Lille Douai) on June 8 provided an opportunity for researchers in this field to exchange on existing methods. Modeling makes it possible to identify the link between pollution sources and receptors. These models help provide an understanding of atmospheric processes and air pollution prevention.   What will the pollution …

Müge Ozman, Télécom École de Management – Institut Mines-Télécom and Cédric Gossart, Institut Mines-Télécom (IMT) One of the problems that we encounter in our research on digital social innovation (DSI) is related with defining it. Is it a catch-all phrase? A combination of three trendy words? Digital social innovations (DSI) are often associated with positive meanings, like openness, collaboration or …

There are numerous applications for remote sensing, from precision agriculture to helping with the deployment of aid in major disasters. Grégoire Mercier, a researcher at IMT Atlantique, explains the key notions of this remote observation method using examples from his research.   Detecting invisible objects from space… this is now possible through remote sensing. This remote observation method is currently …

Nuclear power stations are not the only sources of radioactivity in France. Other sources undeniably include hospitals and the construction industry, for example. Given the potential dangers to health and the environment, such sites have to be permanently tested. SMART, a team of experts in radioactivity from SUBATECH is a necessary third-party actor in this domain. The team brings objectivity …
