Photo-transformation of particles of atmospheric interest and influence on their hygroscopic properties. A levitation technique coupled to the Raman microscope study

In the frame of global warming, confirmed by the Intergovernmental Panel on Climate Change (IPCC), the role of aerosol particles on the climate change is still poorly understood (IPCC, 2007). Hygroscopic properties of the particles play a major role on […]


Electron paramagnetic resonance biosignatures in primitive carbonaceous siliceous rocks: from primitive life on Earth to search of traces of fossil life on Mars

The oldest traces of primitive terrestrial life are fossilized form of carbonaceous microstructures trapped in microcrystalline siliceous rocks (flint , chert in English) . The techniques typically used for their detection (light and electron microscopy , Raman spectroscopy , … […]


Influence of metallic complexation on the photo-degradation of molecules of environmental interest

The fate of organic pollutants (pesticides, medicines, etc.) released in the environment is still an issue of concern. It depends on the mobility of the molecules into the different compartments and on the various degradation routes (chemical, microbiological, etc.). It […]


In situ irradiation NMR and theoretical calculations to screen the photoswitchable properties of new Hexaarylbiimidazole derivatives

Photochromism can be defined as the photoreversible switch between two states. Photochromic compounds have then received great attention due to their fascinating properties, such as thermal stability, fatigue resistance ability, high sensitivity and short response times. Active research has then […]


Regularization for linear inverse problems in ultrafast spectroscopy and high-resolution imaging

Current studies in the laboratory mainly rely on advanced optical spectroscopic techniques involving ultrafast time-resolution or high-resolution imaging. In ultrafast spectroscopy, chemometric analysis of spectral data enables to elucidate reaction pathways to characterize the spectro-dynamic features of intermediate species involved […]


In vivo investigation, by micro-Raman and micro-FTIR spectroscopy, of photoprotection mechanisms of diatoms

This study aims to understand how the photosynthetic organisms can implement specific photoprotection mechanisms when they are exposed to strong light. These mechanisms are still largely unknown, and involves chemical modification (catalyzed by specific enzymes) of the carotenoids in the […]


Study of the interaction between gaseous iodine and aerosols in the atmosphere in case of a severe nuclear power plant accident

During a severe nuclear power plant accident (such as Fukushima), radionuclides of iodine constitute one of the main concerns of the post -accident management because of their high radiotoxicity induced by their affinity for the thyroid. Aerosols and gaseous iodine […]


Photo-evolution of organic compounds adsorbed on the surfaces of mineral particles of atmospheric interest

Organic compounds adsorbed or deposited on the surface of mineral particles may react in the presence of sunlight to form other products that can also impact atmospheric chemistry as shown in recent studies (Ndour et al 2009a, Ndour et al […]


Investigation of surface changes of atmospheric aerosols using environmental atomic force microscopy

There is serious concern about the potential impact of nanoparticles on human health and the environment. Atomic force microscopy (AFM) is a powerful tool for investigating particle morphology and surface properties at the nanometer and micrometer scale. However, when using […]


Chemometrics methodology for air biomonitoring with Raman spectroscopy

In many situations, one would like to be able to rapidly detect the presence of some microorganisms of interest in a given air sample. For instance for armed forces in operation or biomonitoring of cities, it may be crucial to […]

BEA type zeolite nanocrystals stabilized in colloidal suspensions were functionalized with silver nanoparticles. Silver cations were introduced in the BEA type zeolite by ion-exchange treatment. Then the silver nanoparticles in the zeolite were formed via chemical reduction using triethylamine as […]
