New technologies to prevent post-operative hernias

Baptiste PILLET, Mines Saint-Etienne – Institut Mines-Télécom The abdomen experiences intra-abdominal pressure, which varies according to the volume of organs, respiration, muscle activation and any physiological activity. As a consequence, the abdomen must resist forces exerted by this pressure, which can at times be high when coughing or vomiting, or …

An oasis of waste reconverted into ceramic materials

Déchets verre, waste

Transforming industrial waste and unused by-products could make it possible to respond to issues of scarcity for civil engineering resources, recyclability and even reducing use of fossil fuels. Doan Pham Minh, process engineering researcher at IMT Mines Albi, explains several avenues for recycling and reusing materials explored by his work. …

Improve the quality of concrete to optimize construction

Photographie montrant plusieurs blocs de béton

Since the late 20th century, concrete has become the most widely used manufactured material in the world. Its high level of popularity comes alongside recurring problems, affecting its quality and durability. Among these problems is when one of the components in concrete, cement paste, sweats. Mimoune Abadassi, civil engineering PhD …

Technology for improving the recycling of plastics and composites

composites

Plastics and composites aren’t recycled as often as we might wish, as a result of a lack of facilities, the right technologies not yet existing or not being profitable, or hazardous waste deposits. IMT Nord Europe have been working in partnership with manufacturers to develop and improve the available technologies. Plastics …

Graphene, or the expected revolution in electronics: coming soon

Thibaut Lalire, IMT Mines Alès – Institut Mines-Télécom “Material of the 21st century,” a “revolutionary material”: these are some of the ways graphene has been described since it was discovered in 2004 by Konstantin Novoselov and Andre Geim. The two scientists’ research on graphene won them the Nobel Prize in Physics …

Our indoor air is polluted, but new materials could provide solutions

air intérieur

Frédéric Thévenet, IMT Lille Douai – Institut Mines-Télécom We spend 80% of our lives in enclosed spaces, whether at home, at work or in transit. We are therefore very exposed to this air, which is often more polluted than outdoor air. The issue of health in indoor environments is thus …

What do we know about the environmental impact of biocomposites?

Bio-based materials are an alternative to those derived from fossil resources. They have been increasingly promoted in recent years. However, given the recent development of this sector, their real environmental impact is still relatively unknown. Joana Beigbeder, researcher in environmental analysis at IMT Mines Alès, provides an update on the life …

Decontaminating and treating waste from the steel industry

The manufacture of steel produces mineral residues called steel slags, which are stored in large quantities in slag dumps. These present a dual challenge. On the one hand, they are potentially harmful for the environment and health, and on the other hand they are a useful resource for certain industries. …

Innovative approaches to recycling brominated plastics

brominated plastics

Recovering untreated plastic materials and putting them back into the recycling loop through a decontamination line is the challenge of thesis research by Layla Gripon, a PhD student at IMT Lille Douai. These extraction methods contribute to a comprehensive approach to recovering plastic materials, in particular brominated plastics. High consumption …
