Locked-down world, silent cities

silent cities project

Last spring, France decided to impose a lockdown to respond to the health crisis. Our cities came to a standstill and cars disappeared from the streets, allowing residents to rediscover quieter sounds like birdsong. A team of researchers decided to take advantage of this calm that suddenly settled over our …

Smarter models of the ocean

Photographie de l'océan

The ocean is a system that is difficult to observe, whose biodiversity and physical phenomena we still know very little about. Artificial intelligence could be an asset in understanding this environment better. Ronan Fablet, a researcher at IMT Atlantique, presents the projects of the new Océanix Research Chair. What is the objective? To …

Do flame-retardant pillows pollute our homes?

retardateurs de flamme

Chemical additives called flame retardants prevent our furniture from burning too quickly in the event of a fire. But do these molecules pollute the air inside our homes and offices? To answer this question, an ANSES-ADEME research project was launched in 2019 and IMT Mines Alès is taking part in …

A window, and silence!

DeNoize

To combat noise pollution and its effects on human health, DeNoize, a start-up incubated at Mines Saint-Étienne, offers a solution: a window that ‘mutes sound’. This connected window would analyze outside noise and adapt to cancel it out.   Double glazing increases thermal insulation, but when it comes to noise, …

Aerosol therapy: An ex vivo model of lungs

aerosol therapy

A researcher in Health Engineering at Mines Saint-Étienne, Jérémie Pourchez, and his colleagues at the Saint-Étienne University Hospital, have developed an ex vivo model of lungs to help improve medical aerosol therapy devices. An advantage of this technology is that scientists can study inhalation therapy whilst limiting the amount of …

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. …

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 …

Sand, an increasingly scarce resource that needs to be replaced

sable, sand

Humans are big consumers of sand, to the extent that this now valuable resource is becoming increasingly scarce. Being in such high demand, it is extracted in conditions that aren’t always respectful of the environment. With the increasing scarcity of sand and the sometimes devastating consequences of mining at beaches, …

Indoor Air: under-estimated pollutants

Indoor air

While some sources of indoor air pollution are well known, there are others that researchers do not yet fully understand. This is the case for cleaning products and essential oils. The volatile organic compounds (VOCs) they become and their dynamics within buildings are being studied by chemists at IMT Lille …
