Interactions Materials-Microorganisms

Christiine Lors

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, …

What is the social and solidarity economy?

In France, AMAPs (associations for community-supported agriculture) are emblematic examples of the social solidarity economy. But they are not the only social solidarity economy (SSE) organizations. Other examples include cooperative banks, non-profit groups and mutual funds.

The social and solidarity economy (SSE) encompasses organizations that seek to respond to human problems through responsible solutions. Far from being an epiphenomenon, the SSE accounts for a significant share of the economy both in France and around the world. Contrary to popular belief, these principles are far from new. …

What happens to nanoparticles when they become waste?

nanoparticles

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 …

ALGIMEL, a ‘marine’ polystyrene

ALGIMEL is an environmentally-friendly material which is used in a wide range of projects.

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 …

When microorganisms attack or repair materials

microorganisms

Some microorganisms can seriously damage structures made of concrete or stone, leading to billions of euros in damage. Others, on the contrary, have a positive effect as they are able to heal micro-cracks.   They are microscopic, but can cause billions of euros in damage. Microorganisms, such as bacteria, fungi …

When plants help us fight pollution

plants

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 …

Polybioskin, natural skin through more ethical products

Polybioskin

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 …

Recycling carbon fibre composites: a difficult task

carbon fibre

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 …

XENON1T observes one of the rarest events in the universe

XENON1T

The researchers working on the XENON1T project observed a strange phenomenon: the simultaneous capture of two electrons by the atomic nucleus of xenon. A phenomenon so rare that it earned the scientific collaboration, which includes the Subatech[1] laboratory, a spot on the cover of the prestigious journal Nature on 25 …
