Full textIn the research area of Group 13 hydroxide clusters, progress is often hampered by difficult and inefficient synthetic procedures. This has greatly limited the numerous potential applications of Group 13 hydroxide compounds, many of which require large amounts of material. Most relevant to this dissertation is their application as precursors for high quality amorphous metal oxide thin films. Addressing this issue, this dissertation presents a series of Group 13 containing hydroxide compounds of general formula [M 13 (μ 3 -OH) 6 (μ-OH) 18 (H 2 O) 24 ](NO 3 ) 15 which are generated through an efficient, scalable synthetic procedure. Throughout this dissertation, the compounds are generally referred to by their metal content, i.e. [Ga 13 (μ 3 -OH) 6 (μ-OH) 18 (H 2 O) 24 ](NO 3 ) 15 is designated as Ga 13 . Chapter I reviews the literature of inorganic and ligand-supported Group 13 hydroxide compounds with the aim of identifying common structural trends in metal composition and coordinating ligands. This summary is limited to clusters of aluminum, gallium, and indium. Chapter II describes in detail the synthesis and characterization of one such cluster, Al 13 . Following this in Chapter III is the description of the first heterometallic Group 13 hydroxide compound, Ga 7 In 6 , which along with Ga 13 was used as a precursor material for metal oxide thin films in collaboration with Professor Doug Keszler at Oregon State University. Chapter IV describes a series of six Ga/In compounds, as well as two Al/In compounds. Included in this chapter is an analysis of the heat-induced decomposition properties of the Ga/In clusters. Understanding such thermal decomposition is particularly relevant for the use of these compounds as precursor materials, as an annealing step is used to condense the films. Chapter V addresses the potential for post-synthetic modification of the compounds through metal and ligand exchange reactions, an area that also addresses the issue of solution stability of the structures Chapter VI describes the synthesis and characterization of related Group 13 compounds, including two infinite chain structures and additional heterometallic compounds. Lastly, Chapter VII concludes this dissertation and discusses potential areas of future research. This dissertation includes co-authored material and previously published results.

Full textTridecameric inorganic hydroxo/aquo nanoclusters comprise a very small fraction of compounds under the large and varied umbrella of inorganic clusters. The Anderson-Evans cluster is a subset of these larger polymetallic tridecameric clusters. A novel synthesis of M 13 nanoclusters containing the Anderson-Evans cluster as cores has been discovered. This synthesis proceeds with the aid of a key organic reagent, which reacts with the nitrate counter anions of the starting material removing them from the solution. This forces the formation of a higher nuclearity species. Research continues to focus on the generality of the reaction as it applies to both inorganic and organic synthesis, as well as on extensive characterization of the novel clusters by a variety of analytical methods. These nanoelusters have proven to be useful as single-source precursors for the preparation of thin film oxides due to their high purity and crystallinity. Chapter I is a literature review of Anderson-Evans clusters in the context of how they comprise the core substructure in the reported tridecameric nanoclusters. Attention is also given to the numerous clusters or complexes that are absent from this series. Chapter II chronicles the discovery and synthesis of [Ga 13 (μ 3 -OH) 6 (μ 2 -OH) 18 (H 2 O) 24 ](NO 3 ) 15 a nanocluster previously thought to be unstable. Chapter III describes the modification of the reaction to prepare other tridecameric inorganic nanoclusters with increases in yield and purity. Chapter IV reports the isolation of a series of new heterometallic tridecameric nanoclusters and a potential predictive strategy for tuning the metal ratios in the crystalline products. Chapter IV also highlights the application of the nanoclusters as precursors to thin film oxides. Initial characterization of tridecameric inorganic nanoclusters using powder and single crystal XRD, NMR, ToF-SIMS, EPMA and SEM instrumentation is explained in Chapter V. Finally, Chapter VI is a summary and a report of the current standing of a different project aimed at developing a template-assisted self-assembly of organic nanocages using two different ligand classes that were explored. This dissertation includes previously published and co-authored material.

Full textLe poly(acide lactique) (PLA) est un polymère biocompatible et biodégradable dont les applications sont très diverses et qui est principalement produit par polymérisation par ouverture de cycle (ROP) du lactide (LA). Un grand nombre de catalyseurs/initiateurs particulièrement efficaces ont été synthétisés au cours des trente dernières années, tels que les dérivés alcoxy d'aluminium, de zinc et de métaux des terres rares. Par exemple, les catalyseurs/initiateurs à base d'aluminium furent largement exploités pour la ROP du lactide racémique (rac-LA) pour conduite à de remarquables contrôles des masses moléculaires et des distributions de masses ainsi qu'à un bon contrôle de la stéréochimie du polymère final. Encore aujourd'hui, en raison de voies de synthèses chimiques très spécifiques, les exemples de ROP du lactide impliquant des catalyseurs/initiateurs à base d'indium restent rares. Ainsi, nous reportons dans ce manuscrit de thèse cinq principaux chapitres traitant des sujets suivants : i) synthèse de nouveaux complexes d'indium supportés par des ligands dialcoxy-diimino fluorés de type hémi-salen and leur utilisation en ROP du rac-LA ; ii) préparation de nouveaux complexes {phenoxy-imine} d'aluminium et d'indium et leur propriétés catalytiques en ROP immortelle du lactide ; iii) synthèse de complexes bimétalliques d'aluminum et d'indium supportés par des ligands bis(phenoxy-imine) et leur utilisation en ROP du rac-LA ; iv) processus de réduction de type Meerwein-Pondorf-Verley dans des complexes isopropylate imino-phenolate d'aluminum et d'indium ; v) synthèse de polyesters centrés sur la béta-cyclodextrine par ROP contrôlée d'esters et de carbonate cycliques

Full textENGLISH ABSTRACT: A study of the relevant literature revealed anxiety disorders to be of the most prevalent psychiatric disorders of childhood. Prevalence is put at between1 % and 20% in different studies. The purpose of this study was to gather data regarding the prevalence of anxiety in a group of learners in the Western Cape. Literature regarding the different etiological theories of anxiety, the classification of anxiety disorders, their prevalence, the living conditions of the child in South Africa and the assessment of anxiety in children were explored. The study further examined DSM-IV defined anxiety disorder symptoms in a large community sample of 7 to 13 year old learners in the Western Cape. This was done by a simple survey approach, using quantitative measures. Two self-report questionnaires were used, ie the Spence Children's Anxiety Scale (SCAS) and the Screen for Child Anxiety Related Emotional Disorders (SCARED). Results showed that the psychometric properties of the SCAS and the SCARED were moderate (convergent validity) to sufficient (reliability). The original factor structure of the SCAS and the SCARED did not emerge in this sample of learners, although factor analysis did yield evidence of the presence of a number of the hypothesised anxiety categories (ie social phobia, panic disorder, fears and generalised anxiety disorder). Results also indicated that a high percentage of the subjects reported serious anxiety symptoms, namely 22% on the SCAS and 25.6% on the SCARED. The most common anxiety symptoms of the learners in the Western Cape pertained to generalised anxiety disorder, separation anxiety disorder, social phobia, and obsessive-compulsive disorder. Studying the content of the most common responses revealed that symptoms referring to compulsive behaviours and physical separation from the parents were frequent.
AFRIKAANSE OPSOMMING: 'n Studie van die relevante literatuur het aan die lig gebring dat angsversteurings van die mees algemene psigiatriese versteurings tydens die kinderjare is. Die voorkoms daarvan wissel tussen 1% en 20%, en die doel van hierdie studie was om data oor die voorkoms van angs by 'n groep leerders in die Wes-Kaap in te samel. Literatuur oor die verskillende etiologiese teorieë rakende angs, die klassifikasie van angsversteurings, die voorkoms daarvan, die lewensomstandighede van die kind in Suid-Afrika, en die assessering van angs, is ondersoek. Daarna is angsversteurings soos gedefinieer deur die DSM-IV, ondersoek in 'n groot steekproef vanuit die gemeenskap, van 7- tot 13- jarige leerders in die Wes-Kaap. Dit is gedoen deur van 'n eenvoudige opname ontwerp gebruik te maak, en deur kwantitatiewe metodes te gebruik. Twee vraelyste waarin die subjekte inligting omtrent hulself verskaf, is gebruik, naamlik die Spence Children's Anxiety Scale (SCAS) en die Screen for Child Anxiety Related Emotional Disorders (SCARED). Resultate het aangetoon dat die psigometriese eienskappe van die SCAS en die SCARED matig (die konvergerende geldigheid) en voldoende (die betroubaarheid) was. Die oorspronklike faktorstruktuur van die SCAS en die SCARED het nie na vore gekom in hierdie steekproef nie. Faktoranalise het egter die teenwoordigheid van 'n aantal gehipotetiseerde angskategorieë aangedui, naamlik sosiale fobie, paniekversteuring, vrese en algemene angsversteuring. Resultate het ook getoon dat 'n hoë persentasie van die respondente die teenwoordigheid van ernstige angssimptome aangedui het, naamlik 22% op die SCAS en 25.6% op die SCARED. Die mees algemene angssimptome by die leerders in die Wes-Kaap het te doen gehad met algemene angsversteuring, skeidingsangs, sosiale fobie en obsessief-kompulsiewe versteuring. Simptome watte doen het met kompulsiewe gedrag en fisiese skeiding van hulouers, het die populêrste geblyk te wees.
