Abstract:

Nous étudions l'hydratation des ions fluorures et iodures, paradigmes des ions structurants et déstructurants, grâce ` a une étude structurale et dynamique. Concernant la structure, nous observons l'opposé de ce que la définition classique des structurants/déstructurants suggère (F- déforme le réseau de liaisons hydrogènes et I- l'améliore). Ensuite, nous calculons les temps de vie des liaisons hydrogènes halogénures-eau ainsi que les temps de résidence et de réorientation des molécules d'eau de la première couche des anions. Ces mesures confirment la grande stabilité, induite par la force de

Abstract:

Cette étude a pour objectif d’étudier expérimentalement les interactions entre différents anions (chlorure, bromure, nitrate et sulfate) et le silicate de calcium hydraté (C-S-H) afin de construire un modèle thermodynamique capable de prédire cette interaction. Des suspensions de C-S-H synthétisées ont été mises en contact avec différents types de sel (sel de calcium ou d’alcalins). L’influence de la température et de l’incorporation d’aluminium au sein de la structure du C-S-H ont également été prises en compte.L’utilisation d’une méthode d’analyse classique de ce type de système (c’est-à-dir

Abstract:

A range of ion-selective electrodes (ISEs) for the determination of nitrate has been produced based upon rubbery membranes having covalently bound betaine salt sensor molecules. The best performing electrode contained N,N,N-triallyl leucine betaine (6.5 % m/m) covalently bound to polystyrene-block-polybutadiene-block-polystyrene (SBS) (43.5% m/m), with 2-nitrophenyIoctyl ether (2-NPOE) as solvent mediator (40 % m/m) and dicumyl peroxide (DCP) as free radical initiator (10% m/m). The Nemstian slope was -59.1 mV per decade over a linear range of 1 x 10'^-5 x 10"^ mol dm'^ nitrate, a limit of det

Abstract:

Biological selenium reduction has emerged as a viable solution for the removal of toxic selenium from the environment. However, the presence of nitrate hinders selenium reduction by acting as a competitive electron acceptor. The present thesis investigated the use of local mine-impacted sediment as an inoculum for selenium reduction and studied the affect of nitrate on the removal of selenium. Sediment samples, impacted by mining activities, were collected from two vastly different sites of the Elk River Valley. These sediments namely; Goddard Marsh and Mature Tailing Coal, were enriched for s

Abstract:

In this work, reactions of either LiBH\(_4\), ZnCl\(_2\) or Zn\(_3\)N\(_2\) with LiNH\(_2\) have been studied. The presence of CoO significantly affected the products and hydrogen release on heating mixtures of χLiBH\(_4\)-γLiNH\(_2\). The ratios of the l4\(_1\)/amd and the P2\(_1\)/c polymorphs of Li\(_3\)BN\(_2\) in the products have been changed under different conditions studied. On addition of CoO, the temperature of hydrogen release from the χLiBH\(_4\)-γLiNH\(_2\) systems was greatly reduced, starting from 100°C and peaking around 250°C, much lower than 240°C and 330°C without catalyst.

Abstract:

The photochemistry of nitro-compounds is well documented in the literature. However the photochemical behaviour of nitronate anions has not been widely reported. We have studied the photochemical behaviour of a number of steroidal nitronate anions and found that the major products are hydroxamic acid. ketone and alkene. It was found that the yield of products is influenced by the position of the nitro-group. The hydroxamic acids were found to be the major products in the photolysis of 17-nitronate anions. However, it was observed that in these systems the yield of hydroxamic acid was influence

Recently, the large intrinsic surface charge accumulation near InN surface is discovered and this phenomenon results in the positively charged surface states. From the chemical of view, such surface states act as the acidic ligands which can adsorb basic ligands. Based on this property, this thesis investigated the sensing property of InN based anion sensor for the acid, salt and base solutions for the first time. The results show

Abstract:

Investigations pertaining to the rhodium(I)-catalyzed addition of arylboronic acids to (arylsulfonyl)acetonitriles were undertaken. The resulting carbon-carbon bond forming reaction has led to the efficient synthesis of novel stereoselective (Z)-β-sulfonylvinylamines, which upon acidic hydrolysis, afford useful β-keto sulfones possessing a diverse range of aryl and sulfonyl substituents. The synthetic utility of these (Z)-β-sulfonylvinylamines was subsequently explored by generating the corresponding 1-aza-allyl anion equivalents under basic conditions.

Abstract:

Mass spectrometry of negative ions is a convenient method for generating, isolating, and analyzing reactive intermediates that would otherwise be too short lived to detect. This ion approach is especially useful for studying the chemical properties of radicals. In this work, a negative charge-carrying group was attached to lignin model compounds and combined with collision-induced dissociation (CID) to generate and characterize radical species involved in the primary pyrolysis of lignin. The charge-tag served to increase the sensitivity of the model compounds using electrospray ionization mass
