Der volle Inhalt der QuelleStudying the dynamic of particles in the thermosphere – ionosphere and in the exosphere of bodies in the Solar System allows to deepen our understanding of these critical regions that are the bridge between a planet and space. The aim of my thesis was to develop, build and test a neutral particles energy analyser for studying the upper planetary atmospheres: INEA (Ion and Neutral Energy Analyser). The instrument aims to measure the energy structure of the neutral and ion constituents present in the upper atmosphere. To achieve this challenging task, INEA relies on two concepts: an innovative ion source that is based on a carbon nanotube array as an electron emitter and an electrostatic energy analyser which is able to image directly the energy distribution of the particles. During these three years of thesis, a numerical model of INEA was developed in order to meet the instrumental objectives imposed by the measurements needed to characterize the upper atmospheres. At the same time, I have been working on the development of an ion source, also necessary for the optimal operation of INEA, based on the use of carbon nanotubes as electron emitters. The development of the detector, another important part of the instrument has also been conducted. Following the numerical modelling and the work achieved on the different parts of the instrument, a first prototype of INEA has been designed and assembled. This prototype being currently tested. With the work achieved during this thesis, we have been able to propose two instruments for future space missions: M-INEA on the M-MATISSE mission proposed for the ESA M7 call for project, recently selected for a phase A study up to mid-2026, and PSEE, an electron emitter dedicated to the control of PRELUDE SAT, a 6U CubeSat developed by two Japanese universities scheduled to be launched mid-2025

Der volle Inhalt der QuelleThe ionization techniques which proceed from the bombardment of the sample by fast caesium ions (LSIMS) or from the electronebulization of a solution at atmospheric pressure (electrospray, ESI) have been used during this thesis in association with a multi-sectors tandem mass analyzer. From comparison between MS/MS spectra acquired after high energy collisional activation (in the order of kiloelectronvolt) of ionic species arising from one of these ionization methods, it has been shown that the "production mode" of the ions plays a crucial role in dissociation processes via charge-remote fragmentation (CRF). The internal energy of the precursor ions before the collision affects indeed significantly the dissociation behavior after the collisional activation step. Tandem mass spectrometry in combination with high energy collisional activation (CID-MS/MS) and applied to parent ions generated in the LSIMS or ESI ion source allowed the structural elucidation of various natural compounds in complex mixtures and small amounts. It was thus possible to establish unambiguously the double bonds location or branching pattern for aliphatic long chain molecules: serotonin derivatives, acetogenines and glycosphingolipids, with the occurrence of CRF fragment ions that are very specific and highly informative. In addition the structures of cyclic lipopeptides from the surfactine family and oligosaccharides which possess an alditol function and a carboxylic acid group have been characterized

Der volle Inhalt der QuelleIn advancing host-guest (H-G) chemistry, considerable effort has been spent to synthesize host molecules with specific and well-defined molecular recognition characteristics including selectivity and adjustable affinity. An important step in the process is the characterization of binding strengths of the H-G complexes. This characterization is typically performed in solution using NMR or fluorescence. Gas-phase investigation of energetics of H-G systems is of great importance in providing information regarding their intrinsic binding properties. The major portion of this thesis is devoted to the study of the energetics of H-G complexes formed by three hemicryptophane cage hosts with various biologically-relevant guest molecules. Among the existing tandem mass spectrometry-based techniques, here we employ blackbody infrared radiative dissociation (BIRD), low-energy collision induced dissociation (low-energy CID), higher-energy collision dissociation (HCD) and high-pressure CID for measurements of energetics of H-G complexes. These techniques were used either alone, or in combination with each other, or with Rice–Ramsperger–Kassel–Marcus (RRKM) modeling. This work has allowed us to develop the low-energy CID, a promising technique, but so far infrequently used

Pau, 2009. https://theses.hal.science/docs/00/40/14/50/PDF/These_Fanny_CLAVERIE.pdf.
Der volle Inhalt der QuelleLaser ablation inductively coupled plasma mass spectrometry is more and more considered as a tool of choice for solid analysis. The use of femtosecond laser sources permit to improve analytical performances of the coupling thanks to the non-thermal ablation obtained in comparison with the more conventional nanosecond laser used. Through a collaboration between the LCABIE (Laboratoire de Chimie Analytique Bio-Inorganique et Environnement) of Pau and Novalase SA (a company specialized in optical and laser integration), the first integrated femtosecond laser ablation system was designed in 2003. Its unusual characteristics (high repetition rate and scanning beam device) allow to perform some new ablation strategies and open encouraging analytical perspectives in terms of sensitivity and quantification. The potential of this prototype was evaluated through fundamental analyses such as elemental fractionation and characterization of the aerosol produced by laser ablation and through the development of different applications such as analysis of soils and sediments by in-cell isotope dilution, detection of selenoproteins in gel electrophoresis, and determination of uranium isotopic composition of micrometric particles

Der volle Inhalt der QuelleInstalled at the on-line isotope separator ISOLDE at CERN, the tandem Penning-trap spectrometer ISOLTRAP is designed to perform high-accuracy mass measurements on short-lived radionuclides. Based on the determination of the ion cyclotron frequency in a strong magnetic field, the typical relative mass uncertainty is 10-8 with a resolving power of up to R=107. Accurate and precise mass values for specific unstable nuclides are important since they serve e. G. As a stringent test of nuclear models. The main part of this work is the design, installation and characterization of a new Channeltron-detector setup in order to increase the detection efficiency of ISOLTRAP by about a factor of 3. Since a detection efficiency close to 100 percent is reached, true single-ion experiments can be performed for the first time and exotic nuclides further away from the valley of stability and with very short half-lives are now accessible. Concerning mass measurements on short-lived nuclides, the masses of potassium isotopes from 35K (178ms) up to 6K (105s) have been measured with a relative precision of better than 1. 6 10-8. The accurate value of the 35K mass contributes to a stringent test of the isobaric multiplet mass equation for the A=35, T=3/2 isospin quartet

Der volle Inhalt der QuelleNowadays, emissions of atmospheric pollutants from mobile sources such as nitric oxides (NOx) are submitted to more stringent regulations especially within the next Euro 6 which will be implemented in Europe at the beginning of 2014. Up to now commercialized technologies available for the abatement of NOx from lean burn engine (running with a large excess of oxygen) are not capable to remove simultaneously NOx and particulates in lean atmosphere. This study is essentially focused on the NOx conversion to nitrogen via the Selective Catalytic Reduction by using hydrocarbons (HC-SCR) in representative Diesel exhaust gas conditions. This technology is more feasible than the Lean-NOx trap and Urea-SCR systems. Supported gold catalysts on alumina have been developped for the replacement of Pt and Pd less selective. Particular attention was paid to the thermal stability under reaction conditions at 500°C. Among the different synthesis protocols investigated (Deposition-precipitation, Anionic exchange), it was found that the anionic exchange method leads to the best compromise with a larger operating window after ageing. In addition, the reduction of NOx to nitrogen seems structure sensitive, the largest particles being more active than the smallest ones usually thermodynamically instable at high temperature. In this context, such behavior should be profitably used for further practical developments since post-combustion catalysts essentially run at rather high temperature. The second part of this study was dedicated to the modification of Au/Al2O3 catalysts after silver incorporation. Different strategies implemented for Ag incorporation have been examined. Coprecipitation and grafting lead to the formation of bimetallic particles with homogeneous distribution of gold and silver especially via the coprecipitation method. Strong interaction between Au and Ag with further modification of their electronic and adsorptive properties leads to strong deactivation. On the other hand, the segregation of both metals on alumina preserving their intrinsic properties improves the catalytic performances especially after ageing. The influence of different operating condition has been examined showing the best compromise when gold is successively impregnated on Ag/Al2O3
