Abstract:

This dissertation focusses on some advancements in methodology for measuring and analysing dissolved organic carbon (DOC): analysing data from a high resolution sensor generating DOC concentrations, [DOC] and secondly the use of Raman spectroscopy to analyse the composition of DOC. Recent advances in sensor technology have enabled the collection of DOC data with greater frequency over extended time periods than was previously possible through manually collecting water samples. In this research a time series of 30 minute [DOC] data for 2.5 years from Drumtee water, a peaty catchment in Scotland

Abstract:

Hydrogen is a vital component in several different chemical reactions as well as a potential fuel source for the future. The water gas shift (WGS) reaction converts CO and water to hydrogen and CO2. The objective of this work is to first, characterize the potential benefits of the addition of lanthanum oxide (lanthana) to the iron-chromium-copper (Fe-Cr-Cu) oxide catalysts industrially used in high temperature water gas shift processes, and second, analyze these catalysts using in-situ UV-Visible spectroscopy. The benefits of each component in the catalyst are discussed as well as potential be

Dans le domaine UV-visible, ces techniques se basent sur la loi de Beer-Lambert, dont l'application nécessite la connaissance d'un spectre de référence exempt d'absorption. Il est impossible d'obtenir un tel spectre dans le

Abstract:

Many new instrumentation and different instrumental techniques have been developed to deal with increasing complexity of samples encountered. Many researchers also have coupled these instrumental techniques with chemometric algorithms to assist in the quantitative analysis of multi-component samples in the hope of alleviating the need of tedious separation and cleanup procedures. These newer chemometric procedures tend to be complex and difficult to understand and implement and are successful under different circumstances and conditions. In this study, we start from the very simple beginning a

El objetivo principal de esta tesis es el desarrollo de metodologías analíticas rápidas basadas en técnicas espectrofotométricas moleculares y análisis de datos multivariantes. Estas metodologías se han aplicado para la resolución de dos problemas analíticos relacionados con los aceites vegetales como materias primas. <br/>Uno de ellos es la evaluación de las posibilidades que ofrecen los aceites vegetales como precursores de pre-polímeros. Se ha demostrado que la espectroscopía de infrarrojo combinada con tratamiento de datos de segundo orden es una herramienta útil para llevar a cabo el anál

Dissertação de mestrado Erasmus Mundus para obtenção do grau de mestre em Técnicas Laboratoriais Forenses<br>Soil analysis is an important part of forensic science as it can provide vital links between a suspect and a crime scene based on its characteristics. The use of soil in a forensic context can be characterised into two categories: intelligence purposes or court purposes. The core basis of the comparison of sites to determine the provenance is that soil composition, type etc. vary from one place to another. The aim of this project is to ‘map’ soils and predict the location of a sample of

Abstract:

An Ultraviolet to Visible (UV-Vis) spectroscopic analysis based on fuzzy logic approach has been developed for furan content measurement in transformer oil. Following the successful identification and quantification of furan derivatives in transformer oil by ASTM D5837 standard, the new approach is able to approximate the furan content more conveniently and economically. As furan concentration level would determine the absorption intensity in UV-Vis spectral range, the fuzzy logic software model developed would exploit this characteristic to aggregate the furans content level in transformer oi

Abstract:

Le but principal de cette thèse était d'étudier les caractéristiques de la matière organique dissoute (MOD) dans le bassin versant de la Seine. Ce travail a été réalisé dans le cadre du programme de recherche PIREN-Seine. Les travaux présentés ici visaient plus particulièrement à identifier les sources de MOD et à suivre son évolution dans les zones d’étude. L’analyse des propriétés optiques (UV-Visible, fluorescence) de la MOD, couplée aux traitements PARAFAC et ACP, a permis de discriminer différentes sources de MOD et de mettre en évidence des variations spatio-temporelles de ses propriétés

Ce travail s'est inscrit dans le cadre d’un projet de recherche qui vise à synthétiser et caractériser de nouveaux matériaux hybrides organiques-inorganiques pouvant être utilisés dans la fabrication de cellules photovoltaïques, mais avec des éléments moins polluants que les composés actuellement proposés. Pour cela nous avons élaboré et étudié deux nouveaux composés à base d'étain : le bis tétraméthylammonium hexabromostannate ([N(CH₃)₄]₂SnBr₆), et le bis-tétraéthylammonium hexabromostannate ([CH₃-CH₂]₄SnBr₆). Les études expérimentales sont basées sur des analyses thermiques (ATD, DSC, ATG),
