Trains made with recyclable parts

Photographie d'un train Regio2n, même modèle que le démonstrateur en résine thermoplastique développé par le projet Destiny

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 …

STREAM: Bone tissue model culture

STREAM

The STREAM project, which Mikhaël Hadida is working on at Mines Saint-Étienne, aims to develop a controlled, carefully-managed bone tissue culture platform. This system would facilitate observation in order to study the mechanisms involved in bone tissue by reducing the costs and time required for research.     A culture …

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 …

Recovering knowledge of local, traditional building materials

building

Why is an old country farmhouse more pleasant in summer than a modern city building? Traditional building materials and natural stone provide old buildings with better thermal and hygrometric properties. Unfortunately, they often lack the technical characterizations they need to find their place in the construction industry. The European regional …

A sorting algorithm to improve plastic recycling

plastics

Producing high-quality raw materials from waste is contingent on effective sorting. Plastics from waste electrical and electronic equipment (WEEE) are no exception. To help solve this problem, researchers at IMT Mines Alès have developed a selective automation algorithm designed for these plastics. It can be integrated in new industrial-scale sorting …
