Activation and Capture of Carbon Dioxide and Carbon Disulfide by N-Containing Compounds
(2013-12-04)The interaction between carbon dioxide (CO2) and N-compounds such as 1,8-diazobicyclo[5.4.0]undec-7-ene (DBU) has been extensively studied in the Jessop Lab. Carbon disulfide (CS2) is the sulfur congener of CO2, although ... -
ADDRESSING CHALLENGES IN CATALYSIS AND ENERGY: SELECTIVE GRAFTING FUNCTIONALITY ONTO MESOPOROUS SILICAS AND ORGANIC HYDRIDES FOR THE REGENERATION OF AMMONIA BORANE, A HYDROGEN STORAGE MATERIAL
(2011-09-12)Ordered mesoporous silicas have been shown to have a variety of useful applications ranging from adsorbents for containments to supports for catalysts. While these materials have received a good deal of attention in the ... -
Advances in 5-(Hydroxymethyl)Furfural Production From Cellulose Via CO2-Catalysis
The global economy must make a radical shift to lower carbon emissions to avert large-scale impacts from climate change. Fuels derived from widely available biomass such as macroalgae, have the potential to limit the CO2 ... -
Advances in Directed Ortho Metalation: Copper- and Rhodium-Catalyzed Allylic Substitution and the DMG Dance
(2015-08-13)Chapter one of this thesis describes preliminary efforts towards the development of the rhodium-catalyzed allylic arylation reaction employing nucleophiles containing ortho-DMGs (directed metalation groups). Unfortunately, ... -
Advances in Metal-Catalyzed C–H Borylation and Multicomponent Allylic Substitution Reactions
(2015-08-26)Chapter one of this thesis describes the iridium-catalyzed ortho-selective C–H borylation reaction of tertiary benzamides. An iridium(I) complex paired with an electron-deficient phosphine ligand allows for efficient C–H ... -
Advances in the synthesis of indazoles: regioselective C-7 functionalization by directed ortho metalation and progress towards indazole based azaborine compounds
As one of the fundamental heterocyclic building blocks, indazole and its derivatives have spurred significant research interest and patented applications. In particular, C-7 substituted indazole derivatives are of prime ... -
Aggregation and Redispersion of Switchable Latexes
(2011-09-26)Amidine-based switchable surfactants can be used as stabilizers during emulsion polymerization and the resulting latexes can then be destabilized by the removal of CO2. High Tg polymers have been successfully redispersed, ... -
Alternative Sample Introduction Techniques to Nebulization of Solutions in Inductively Coupled Plasma Spectrometry
The objective of this thesis was to explore alternative sample introduction techniques for inductively coupled plasma mass spectrometry (ICPMS) and optical emission spectrometry (ICPOES). This work was conducted as part ... -
Amino Acid-Type Specific Incorporation of Stable 17O Isotopes into Yeast Ubiquitin
Stable isotopic labeling is an important part of structural biology by multidimensional NMR spectroscopy. Novel stable isotopic labeling methods have continuously been developed to enhance protein NMR spectroscopy. Protein ... -
Amorphous Organic Molecular Glasses for Photovoltaic Applications
Significant progress has been achieved recently in the development of solution-processed organic photovoltaic devices, and they are now in the early stages of commercialization. However, achieving a smooth and homogenous ... -
ANALYSIS OF POTENTIALLY TOXIC BIOACCESSIBLE ELEMENTS IN LOCALLY AVAILABLE BREAD USING CONTINUOUS ON-LINE LEACHING COUPLED TO INDUCTIVELY COUPLED PLASMA MASS SPECTROMETRY
(2014-07-22)A previously developed, efficient and simple on-line leaching method was used to assess the bioaccessible fraction of potentially toxic elements (Cr, As, Pb and Cd) in whole wheat brown and white bread samples. Artificial ... -
Applications of Mass Spectrometry in the Studies Concerning bldA Regulation of Natural Product Biosynthesis in Streptomyces sp.
The Streptomyces are a genus of soil-dwelling Gram-positive bacteria that produce a variety of secondary metabolites; they have even been dubbed as ‘antibiotic factories’ as a typical genome can contain as many as 30 ... -
