Bone implants to stimulate bone regeneration

Mines Saint-Étienne’s Centre for Biomedical and Healthcare Engineering (CIS) seeks to improve healthcare through innovations in engineering. David Marchat, a materials researcher at CIS, is working on developing calcium phosphate-based biomaterials. Due to their ability to interact with living organisms, these bone implants can help regenerate bones.   This article is part of our dossier […]

An autonomous contact lens to improve human vision

Two teams from IMT Atlantique and Mines Saint-Étienne have developed an autonomous contact lens which is powered by an integrated flexible micro-battery. This invention is a world first that opens new health prospects, whilst also opening the door for scientists to develop other human-machine interfaces.   Human augmentation, a field of research that aims to […]

What happens to nanoparticles when they become waste?

For the past twenty years, industry sectors across the board have been producing a wide range of nanomaterials. They have developed rapidly and with little in the way of regulation. This has led to a regulatory vacuum when it comes to the end-of-life management of these nanomaterials. Little is known about the environmental and health […]

ALGIMEL, a ‘marine’ polystyrene

In the future, materials will not only need to be more efficient; it will also be essential that they are environmentally friendly. With this in mind, researchers from IMT Mines Alès who specialize in bio-sourced materials are working on this project.  Over the past few decades, they have been trying to develop environmentally-friendly alternatives to […]

When plants help us fight pollution

To help reduce or stabilize soil and water pollution, plants provide a rather effective yet inexpensive solution. They must be implemented on a case-by-case basis and could be used in a wide variety of sites.   According to the French Environment and Energy Management Agency (Ademe), 300,000 to 400,000 industrial or mining sites in France […]

Polybioskin, natural skin through more ethical products

Skin contact products, whether for medical, sanitary or cosmetic purposes, have two major drawbacks: they are neither recyclable nor biodegradable. The Polybioskin H2020 project aims to correct these aspects which are out of step with consumers’ growing environmental awareness and concerns. Launched two years ago, the Polybioskin project brings together 12 European partners, including IMT […]

Romain Quey, all about polycrystals

A recent winner of a CNRS Bronze medal, Romain Quey is a materials science researcher at the Georges Friedel[1] laboratory at Mines Saint-Étienne. He focuses especially on the deformation of metallic polycrystalline materials. In the following interview for I’MTech, he presents his research, between synchrotron radiation and digital simulation.     Could you define what […]

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 […]
