Recycling carbon fibre composites: a difficult task

Carbon fibre composite materials are increasingly widespread, and their use continues to rise every year. Recycling these materials remains difficult, but is nevertheless necessary at the European level for environmental, economic and legislative reasons. At IMT Mines Albi, researchers are working on a new method: vapo-thermolysis. While this process offers promising results, there are many steps […]

A mini revolution in railway catenaries

The decade-long ACCUM project carried out by SNCF, Stratiforme Industries, the Valenciennes Railway Testing Center and IMT Lille Douai has led to the development of a new catenary cantilever system for railways. This advance represents a major change in this field, where equipment has seen little change over the past 50 years.   When asked […]

In search of forgotten cements

Out of the 4 billion tons of cement produced every year, the overwhelming majority is Portland cement.  Invented over 200 years ago in France by Louis Vicat — then patented by Englishman Joseph Aspdin —Portland is a star in the world of building materials. Its almost unparalleled durability has allowed it to outperform its competitors, […]

Sand, an increasingly scarce resource that needs to be replaced

Humans are big consumers of sand, to the extent that this now valuable resource is becoming increasingly scarce. Being in such high demand, it is extracted in conditions that aren’t always respectful of the environment. With the increasing scarcity of sand and the sometimes devastating consequences of mining at beaches, it is becoming crucial to […]

MAGIC: the wonders of infrared camouflage

The MAGIC project aims to develop a camouflage technique against infrared cameras. Mines Saint-Etienne is using its expertise in the optical properties of materials to achieve the project’s objective. Funded by the DGA and supported by the ANR, MAGIC primarily focusses on military applications. Jenny Faucheu, a researcher on the project at Mines Saint-Étienne, explains the […]

Indoor Air: under-estimated pollutants

While some sources of indoor air pollution are well known, there are others that researchers do not yet fully understand. This is the case for cleaning products and essential oils. The volatile organic compounds (VOCs) they become and their dynamics within buildings are being studied by chemists at IMT Lille Douai. When it comes to […]

Without noise, virtual images become more realistic

With increased computing capacities, computer-generated images are becoming more and more realistic. Yet generating these images is very time-consuming. Tamy Boubekeur, specialized in 3D Computer Graphics at Télécom ParisTech, is on a quest to solve this problem. He and his team have developed new technology that relies on noise-reduction algorithms and saves computing resources while […]
