Computational Investigation and Prediction of Mechanisms and Stereocontrol in Complex Organic Reactions

Creator:: Pattawong, Ommidala
Abstract:: Complex organic transformations, such as the addition of pyrrole to ketene using planar chiral organocatalyst (*PPY), the four-component anhydride- Manniach reactions, and the site-selective desymmetrization of meso-1,2-diol, are remarkable synthetic reactions that provide high yield and high selectivity. However, the exact mechanism and origins of stereocontrol for theses synthetic organic...

Human exposure to polycyclic aromatic hydrocarbons : global cancer risk and metabolism

Creator:: Motorykin, Oleksii
Abstract:: In recent decades, there has been increased attention on human exposure to, and subsequently toxicity of, Polycyclic Aromatic Hydrocarbons (PAHs). PAHs are widespread organic pollutants and some have been shown to be toxic, carcinogenic and mutagenic. This research was focused on understanding the link between global PAH emissions and lung...

Structure-property relationships of oxides with hexagonal AMO₃ and brownmillerite related structures

Creator:: Jiang, Peng
Abstract:: Transition metal oxides exhibit potential in various application fields due to the special d-electrons. Solid state chemistry focuses on discovering the structure-property relationships. The work in this thesis mainly discusses compounds with hexagonal or brownmillerite-type structure and their practical properties. Hexagonal YIn[subscript 1-x]Fe[subscript x]O₃ (x = 0-0.3, 0.7-1.0) phases have...

Tracking semi-volatile organic pollutants in remote lake systems

Creator:: Usenko, Sascha
Abstract:: SOCs volatility and persistence properties cause many SOCs to become ubiquitous in the environment as well as accumulate in areas with lower temperatures such as polar or orographic regions. Many anthropogenic SOCs pose a serious risk to human and ecosystem health because of their persistent, bioaccumulative, and toxic properties in...

A new trigonal huntite material and subgroup relationships between crystallographic space groups

Creator:: Hruschka, Michael Archimedes and Hruschka, Michael A.
Abstract:: The use of an adjacency matrix to determine distant (not maximal or minimal) subgroup and supergroup relationships between crystallographic spacegroup types is described. Full lists of space-group types that are supergroups and subgroups for every space-group type were compiled. A list of the space-group types connected to each space-group type...

Synthetic studies on necic acids of pyrrolizidine alkaloids

Creator:: Lee, Nadine Chauyi
Resource Type:: Dissertation

A microcomputer automated anodic stripping voltammetric analyzer for trace heavy metal speciation

Creator:: Dewald, Lamar Robert
Abstract:: An automated instrument based on a single-board microcomputer was developed for use in voltammetric analyses. Operator input of numerous experiment parameters allows any type of voltammetric analysis to be implemented and multiple scans to be run unattended. A three operational amplifier potentiostat is used to control the cell voltage and...

A quantitative description of the silver/aqueous cyanide electrolyte interface and the effect of the interface on the rate of electrodeposition of silver

Creator:: Jewett, James Richard
Resource Type:: Dissertation

A study of simultaneous diffusion of Ca²⁺ and Sr²⁺ in alkali chlorides

Creator:: Machida, Hisashi
Abstract:: The simultaneous diffusion of Ca 2+ and Sr 2+ ions in purified single crystals of KC1 and NaC1 was studied over the temperature ranges from 451°C to 669°C in KC1 and from 448°C to 683°C in NaCl. A radioactive tracer technique was used in two types of measurements: diffusion from...
