Fuel cells in the hydrogen age

Hydrogen-powered fuel cells are recognized as a clean technology because they do not emit carbon dioxide. As part of the energy transition aimed at transforming our modes of energy consumption and production, the fuel cell therefore has a role to play. This article will look at the technologies, applications and perspectives with Christian Beauger, a […]

Trains made with recyclable parts

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 to lower the environmental cost […]

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 in France by the Malabar […]

A sorting algorithm to improve plastic recycling

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 machines.   How will your […]

What is a lithium-ion battery?

The lithium-ion battery is one of the best-sellers of recent decades in microelectronics. It is present in most of the devices we use in our daily lives, from our mobile phones to electric cars. The 2019 Nobel Prize in Chemistry was awarded to John Goodenough, Stanley Wittingham, and Akira Yoshino, in recognition of their initial […]

Interactions Materials-Microorganisms

This book is devoted to biocolonization, the biodeterioration of materials and possible improvements in their performance. Many materials age according to their use and their environment. The presence of microorganisms can then lead to biodeterioration. However, these can also help protect structures, provided their properties are used wisely. Christine LORS, researcher at IMT Lille Douai […]

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 […]
