This paper analyzes the fate of 71 priority and emerging organic contaminants all along the treatment trains of sewage sludge treatment facilities in Paris including dewatering by centrifugation, thermal drying and anaerobic digestion. It aimed at proposing and applying a mass balances calculation methodology to each process and pollutant. This dat...
Sampling of the vast conformational landscape of organic compounds remains a challenging task in computational chemistry, especially when it comes to the characterization of soft-degrees of freedom and relatively small energy barriers between different local minima. Therefore, studying the intrinsic properties of isolated molecules using focused ex...
Near-infrared spectrum analysis coupled with partial least squares regression can predict anaerobic digestion performances. Nonetheless, due to the complexity and diversity of organic matter, a detailed assessment of the effects of the composition of organic matter on biogas production remains a great challenge. Based on 275 samples representing a ...
Airborne PM pollution has emerged out as a critical issue all across the world. Quantitative and qualitative source analysis is becoming imperative to imply effective emission control strategies to reduce ambient air pollutants. Receptor oriented models, based on the statistical approach, have been developed to analyze various characteristics of th...
Receptor models (RMs) as Positive Matrix Factorization (PMF) have become, one of the most used methodology for PM source apportionment in Europe. Evidence for this is given by the recent common protocol for RMs users, proposed by JRC of the European Commision in 2014. These last decades, the chemical composition of Particulate Matter (PM) is increa...
While using alternative aviation fuels represents a promising approach to reduce the industry’s impact on climate change and local air quality, the influence of these new fuels on the chemical composition of exhaust plumes, and, in particular, on aviation-produced aerosols must be assessed. This paper studies the influence of using alternative jet ...

Nitrification plays an important role in nitrogen turnover in composting process. It has been believed that nitrification occurs mainly during the maturation phase due to the elevated temperature during the active phase of composting. In this work, the intense biodegradation of organic matters is demonstrated to be another negative impact on the am...
We prepared a new two-dimensional oxyantimonide, BaTi(2)Sb(2)O, which shows a superconducting transition at 1.2 K, representing the first superconductivity in a system with Ti(3+) (d(1)) in a square lattice. The TiO(2)Sb(4) mixed anionic coordination stabilizes a unique half-filled Ti d(xy) orbital configuration in Ti(2)O plane, which is analogous ...
Previous experiments with organo-metallic compounds like ferrocene, nickelocene and magnesocene showed that a pure spectrum must be obtained on the residual gas mass analyser before running successfully on the ion source. In collaboration with the chemistry department of the University of Caen, LCMT-ENSI Caen, the synthesis of these metallocene com...
We describe the spontaneous photoinduced patterning of azo-dye polymer films. We have observed that the illumination of an azo-dye polymer film by a uniform single laser beam with normal incidence leads to a self-structurization process that results in the formation of well-ordered submicrometer-sized structures whose organization depends on the li...
