Atmospheric reactive trace gases: low concentrations, major consequences

Despite only being present in very small quantities, trace gases leave their mark on the atmospheric composition. Since they are reactive, they may lead to the formation of secondary compounds such as ozone or aerosols that have a significant impact on health and the climate. IMT Lille Douai is a …

What is a volatile organic compound (VOC)?

VOC, Volatile organic compound

Pollution in urban areas is a major public health issue. While peaks in the concentration of fine particles often make the news, they are not the only urban pollutants. Volatile organic compounds, or VOC, also present a hazard. Some are carcinogenic, while others react in the atmosphere, contributing to the …

Millimeter waves for mobile broadband

Une ondes millimétriques, millimeter waves

5G will inevitably involve opening new frequency bands allowing operators to increase their data flows. Millimeter waves are among the favorites, as they have many advantages: large bandwidth, adequate range, and small antennas. Whether or not they are opened will depend on whether they live up to expectations. The European …
