SYNTHESIS AND REACTIVITY OF DINUCLEATING DI(DIAMINO)PHENOLATE LIGANDS FOR ENFORCING COOPERATIVITY by Xiaofang Zhai B.Sc., University of Waterloo, Waterloo, ON, Canada, 2015 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Chemistry) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) December, 2017 © Xiaofang Zhai, 2017 Abstract A new single-frame dinucleating di(diamino)phenolate ligand L has been synthesized and fully characterized, and its coordination chemistry with zinc precursors featuring ethyl, alkoxide, acetate and amide leaving groups has been investigated. Reaction of ligand L with diethyl zinc and Zn[N(SiMe3)2]2 led to the formation of a trinulcear zinc complex 1 (L)Zn3(CH2CH3)4 and a dinuclear zinc amide complex 4 (L)Zn2[N(SiMe3)]2, respectively. Deprotonation of ligand L followed by salt metathesis with Zn(OAc)2 gave rise to a trinuclear zinc complex 3 [(L)Zn3](µ- OAc)4. The alkyl zinc complex 1 reacted with benzyl alcohol to afford a dinuclear alkoxy zinc 1 13 1 complex 2 [(L)Zn2](µ-OCH2Ph)2. Complexes 1-3 were fully characterized by H-NMR, C{ H}- NMR, COSY, NOESY, HSQC and HMBC NMR spectroscopy and elemental analysis. The solid-state structures of Zn complexes 1-4 were characterized by single-crystal X-ray crystallography. The catalytic activities of complex 1 and 2 towards ring opening polymerization of racemic lactide (rac-lactide) have been studied. Complex 2 showed better control over molecular weight and dispersity than complex 1, and generated heterotactically inclined poly(lactic acid). -

Land Smith A THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY GRADUATE PROGRAM IN ENGLISH CALGARY, ALBERTA JANUARY, 2021 © Mallory E. Land Smith 2021 MELS ii Abstract Sina Queyras, in the essay “Lyric Conceptualism: A Manifesto in Progress,” describes the Lyric Conceptualist as a poet capable of recognizing the effects of disparate movements and employing a variety of lyric, conceptual, and language poetry techniques to continue to innovate in poetry without dismissing the work of other schools of poetic thought. Queyras sees the lyric conceptualist as an artistic curator who collects, modifies, selects, synthesizes, and adapts, to create verse that is both conceptual and accessible, using relevant materials and techniques from the past and present. This dissertation responds to Queyras’s idea with a collection of original poems in the lyric conceptualist mode, supported by a critical exegesis of that work. -

This advanced technology shows promise in enabling large scale interdisciplinary studies that require high throughput and accurate manipulation of reagents. Each droplet acts as a micro-sized reactor where complex reactions can be carried out on the micro-scale by splitting, mixing, sorting and merging droplets. -
Microfluidic Studies of Biological and Chemical Processes
Microfluidic Studies of Biological and Chemical Processes by Ethan Tumarkin A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Chemistry University of Toronto © Copyright by Ethan Tumarkin, 2012 Microfluidic Studies of Biological and Chemical Processes Ethan Tumarkin Doctor of Philosophy Department of Chemistry University of Toronto 2012 Abstract This thesis describes the development of microfluidic (MF) platforms for the study of biological and chemical processes. In particular the thesis is divided into two distinct parts: (i) development of a MF methodology to generate tunable cell-laden microenvironments for detailed studies of cell behavior, and (ii) the design and fabrication of MF reactors for studies of chemical reactions. First, this thesis presented the generation of biopolymer microenvironments for cell studies. In the first project we demonstrated a high-throughput MF system for generating cell-laden agarose microgels with a controllable ratio of two different types of cells. The MF co-encapsulation system was shown to be a robust method for identifying autocrine and/or paracrine dependence of specific cell subpopulations. In the second project we studied the effect of the mechanical properties on the behavior of acute myeloid leukemia (AML2) cancer cells. Cell-laden macroscopic agarose gels were prepared at varying agarose concentrations. A modest range of the elastic modulus of the agarose gels were achieved, ranging from 0.62 kPa to 20.21 kPa at room temperature. We observed a pronounced decrease in cell proliferation in stiffer gels when compared to the gels with lower elastic moduli. The second part of the thesis focuses on the development of MF platforms for studying chemical reactions. -

INDIUM COMPLEXES and THEIR ROLE in the RING-OPENING POLYMERIZATION of LACTIDE by AMY FRANCES DOUGLAS B.Sc., the University of V
INDIUM COMPLEXES AND THEIR ROLE IN THE RING-OPENING POLYMERIZATION OF LACTIDE by AMY FRANCES DOUGLAS B.Sc., The University of Victoria, 2005 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE in THE FACULTY OF GRADUATE STUDIES (Chemistry) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) April 2008 Amy Frances Douglas, 2008 ABSTRACT The synthesis and characterization of a series of chiral indium complexes bearing a tridentate NNO ligand are reported. The ligand 2-[[[(dimethylamino)cyclohexyl]amino]methyl]- 4,6-bis(tert-butyl) phenol (H2NNO) was synthesized via a previously published procedure and bound to indium by both a protonolysis and salt metathesis route. A dimethylated indium complex (NNO)InMe2 (1) was isolated by reaction of InMe3 with H2NNO. A one-pot salt metathesis route was used to produce a unique mixed-bridge dinuclear indium complex [(NNO)InCl]2(µ-OEt)(µ-Cl) (3) from a mixture of indium trichloride, potassium ethoxide and the monopotassiated salt of the ligand, KH(NNO). Direct reaction of KH(NNO) and indium trichloride resulted in the formation of (NNO)InCl2 (4) which was carried forward to 3 by reaction with sodium ethoxide. The complex 3 is active for the ROP of β-butyrolactone ε-caprolactone and lactide and is the first reported indium-based catalyst for lactide or β-butyrolactone ROP. Kinetic studies of 3 for ROP of LA revealed that catalyst was well-behaved, and that the rate was first order with regard to lactide and catalyst. The enthalpy and entropy of activation for the ROP were experimentally determined. -

FACTORS AFFECTING THE GROWTH AND FRAGMENTATION OF POLYFERROCENYLSILANE DIBLOCK COPOLYMER MICELLES By Jieshu Qian A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Graduate Department of Chemistry University of Toronto © Copyright by Jieshu Qian, 2013 FACTORS AFFECTING THE GROWTH AND FRAGMENTATION OF POLYFERROCENYLSILANE DIBLOCK COPOLYMER MICELLES Jieshu Qian Doctor of Philosophy Graduate Department of Chemistry University of Toronto 2013 Abstract Polyferrocenylsilane (PFS) diblock copolymers self-assemble in selective solvents to form one-dimensional micelles for a broad range of polymer compositions and experimental conditions, driven by the crystallization of the PFS block that forms the micelle core. The most striking feature of these micelles is that they remain active for further growth. They can be extended in length when additional polymer, dissolved in a good solvent, is added to a solution of the pre-existing micelles. This thesis describes several studies investigating the factors that affect the growth and fragmentation of PFS diblock copolymer micelles in solution, with a particular emphasis on polyisoprene-PFS (PI-PFS) diblock copolymers. The goal of my research was trying to provide deeper understanding of this crystallization-driven self-assembly (CDSA) process. In an attempt to understand the growth kinetics of the PI-PFS cylindrical micelles, I added tiny amount of short micelle seeds into supersaturated solution of the same polymer, and followed the micelle growth by light scattering. The data analysis showed that the increase of micelle length could be described by an expression with two exponential decay terms. In another ii attempt to examine the factors that may affect the growth behavior of the PI-PFS micelles, I found that PI-PFS long micelles underwent fragmentation when they were subjected to external stimuli, e.g. -
