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. …

The Destiny project proposes a new process to manufacture parts for the railway and aeronautical industries. It uses a thermoplastic resin, which enables the materials to be recycled while limiting the pollution associated with manufacturing them.      It is increasingly critical to be able to recycle products so as …

Temporary tattoos for brain exploration

A team of bioelectronics researchers at Mines Saint-Étienne has developed a new type of electroencephalogram electrode using a temporary tattoo technique. As effective as traditional electrodes, but much more comfortable, they can provide extended recordings of brain activity over several days.    The famous decalcomania transfer technique – made popular …

Protective masks: towards widespread reuse?

masks

How can protective masks be recycled and reused without risking safety? Scientists, medical practitioners and manufacturers have teamed up to explore different treatment methods. As part of this consortium, IMT Atlantique researchers are studying the impact of decontamination processes on mask performance.   Surgical and FFP2 masks are intended for single …

What is tribology?

tribology

The science of friction: this is the definition of tribology. Tribology is a focal point shared by several disciplines and an important field of study for industrial production. Far from trivial, friction is a particularly complex phenomenon. Christine Boher, a tribologist at IMT Mines Albi[1], introduces us to this subject.   …

Twin ERC grants for research on the aorta

ERC

In 2015, the Mines Saint-Étienne engineering and health center was awarded two grants by the European Research Council (ERC). This funding was for two five-year projects on ruptured aortic aneurysms in the Sainbiose laboratory[1]. Pierre Badel received a €1.5 million starting grant (young researcher grant), and Stéphane Avril received a €2 million consolidator grant (for putting together …

I like this, I don’t like that

tactile perception

We like the soft feel of a cat’s fur, but we don’t like mud, which is slimy, nearly as much. Why is this? We are told that everyone’s tastes are different. But that does not keep scientists from trying to find answers. Jenny Faucheu, a researcher at Mines Saint-Étienne, has …
