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, …

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 …

Medicine for Materials

non-destructive inspection

Did you know that materials have health problems too? To diagnose their structural integrity, researchers are increasingly using techniques similar to those used in the medical field for humans. X-rays, temperature checks and ultrasound imaging are just a few of the tools that help detection of abnormalities in parts. The …

Composite Materials: the race to keep going faster

composite materials

In the world of materials, composites are currently undergoing a transformation that is just a significant as the plastics boom in the 1960s. To massively integrate these materials into high-volume production markets—automotive, aeronautics, rail, etc.—manufacturers must further reduce the time it takes to mold the parts. This complex goal is …

Flax and hemp among tomorrow’s high-performance composite materials

Chung-Hae Park, Mines Douai, Composite materials

Composite materials are increasingly being used in industry, especially in the transport sectors (automotive and aeronautics). These lightweight and multifunctional materials have great potential for limiting environmental footprint, and will play a major role in the materials of future. At Mines Douai, Chung-Hae Park is contributing to the development of …

Agro-based composite materials – a Mines area of expertise

Mines Alès, Mines Douai, Agro-based composite materials

The materials of the future need to be more than just high-performance. They must also be environmentally friendly: more recyclable and based on renewable resources. This is why scientists and industrialists are taking a closer look at composite materials developed from plant fibers. They represent a major research focus for …

Recycling concrete and sediment to create new materials

Mines Douai, Concrete, sediments

How can we meet the needs for construction materials in an environmentally responsible manner? Recycling could be the solution, but it is not yet easy to create high-performance and eco-friendly materials using waste. At the conference on Natural Resources and Environment, which took place on November 5-6 2014 at Institut …

When engineering helps improve healthcare

healthcare

Editorial.   Tomorrow’s medicine will be at least 4P: personalized, preventive, predictive, participative. ‘At least,’ because some would readily add “precise,” “proof” (evidence-based), “pathway-based” etc. Beyond naming this type of medicine and determining the correct number of Ps, medicine is clearly undergoing a profound change. A transformation supported in part …

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 …
