Unraveling the Uptake of Glyoxal on a Diversity of Natural Dusts and Surrogates: Linking Dust Composition to Glyoxal Uptake and Estimation of Atmospheric Lifetimes

Michel Rossi, Hui Chen

The uptake of glyoxal (Gly) on 28 different samples with varying mineralogical origins, such as clays, mineral proxies, and natural dusts from the major arid regions of the Earth, was determined. Experiments were performed at ambient temperature inside a K ...

, ,

Knudsen flow experiments and its interpretation in terms of adsorption/desorption kinetics as well as quantitative uptake on substrates of interest is presented together with the description of critical design parameters of the Knudsen Flow Reactor (KFR). ...

The dynamics of TiO2 conduction band electrons were followed with a novel broadband synchrotron-based transient mid-IR spectroscopy setup. The lifetime of conduction band electrons was found to be dependent on the injection method used. Direct band gap exc ...

Royal Society of Chemistry2013

In this laboratory study a multidiagnostic experimental approach including Fourier transform infrared (FTIR) absorption of 1 to 2 mu m thick polycrystalline ice films, residual gas mass spectrometry (MS) and total pressure measurement were employed. Both a ...

Méthode de décapage sélective d'un matériau sur un substrate en quartz par l'utilisation d'un faisceau -induit

Patrik Willi Hoffmann, Michel Rossi, Tristan Bret, Xavier Multone

A method and apparatus for local beam processing using a beam activated gas to etch material are described. Compounds are disclosed that are suitable for beam-induced etching. The invention is particularly suitable for electron beam induced etching of chro ...

2012

The HOCl heterogeneous reaction on frozen natural (NSS) and recrystallized (RSS) sea salt KCl and NaCl solutions was studied using a low pressure flow reactor in order to measure the uptake coefficient gamma and products of reaction The HOCl sample used in ...

Characterization of surface functional groups present on laboratory-generated and ambient aerosol particles by means of heterogeneous titration reactions

Michel Rossi, Michel Guillemin

A Knudsen flow reactor has been used to quantify surface functional groups on aerosols collected in the field. This technique is based on a heterogeneous titration reaction between a probe gas and a specific functional group on the particle surface. In the ...

2009

The aim of this study was to evaluate adverse effects of multiwalled carbon nanotubes (MWCNT), produced for industrial purposes, on the human epithelial cell line A549. MWCNT were dispersed in dipalmitoyl lecithin (DPL), a component of pulmonary surfactant ...

2009

This article, the fourth in the series, presents kinetic and photochemical data sheets evaluated by the IUPAC Subcommittee on Gas Kinetic Data Evaluation for Atmospheric Chemistry. It covers the gas phase and photochemical reactions of organic halogen spec ...
