Ocean remote sensing: solving the puzzle of missing data

Ocean Remote sensing, data, IMT Atlantique

The satellite measurements that are taken every day rely greatly on atmospheric conditions, the main cause of missing data. In a scientific publication, Ronan Fablet, a researcher at Télécom Bretagne, proposes a new method for reconstructing the temperature of the ocean surface to complete incomplete observations. This reconstructed data provides …

Removing pollutants from our homes

Pollutants, Département SAGE, Mines Douai, Frédéric Thévenet, COV

Indoor air is polluted with several volatile organic compounds, some of which are carcinogenic. Frédéric Thévenet, a researcher at Mines Douai, develops solutions for trapping and eliminating these pollutants, and for improving tests for air purifying devices.   We spend nearly 90% of our time inside: at home, at the …

Bioplastics: “still a long road to higher performance”

Bioplastics, Mines Douai

As required by environmental transition, materials of the future must be “greener”. Bioplastics in particular have become a main focus of attention, and are often presented as the solution to the pollution caused by the plastics we use every day, which can take hundreds of years to decompose. Patricia Krawczak, …

Biosensors for monitoring herbicides in water

Ingrid Bazin, Mines Alès, biocapteurs, herbicides

Water preservation and management involves detecting its pollutants. Among those most frequently found in surface water and groundwater are weed-killers, such as the well-known glyphosate. At Mines Alès, Ingrid Bazin is working on developing innovative bioreceptors to monitor these small molecules, with the aim of one day providing the water …
