Polylcaprolactone-Based Microfluidic Devices : Fabrication Methods and Applications in Low-Cost Analytical Devices

Creator:: Heist, Christopher A.
Abstract:: The overall concept of reducing laboratory operations to a scale that fits on a single microfluidic chip has been an attractive area of research over the last several decades. Despite a surge in research, few commercial success stories have been written. Lab-on-a-chip technologies have the capability to be cost effective...

Hydrogen abstraction from substituted t-butylbenzenes

Creator:: Harvey, Robert Louis
Abstract:: A study of the relative rates of the alkyl hydrogen abstraction from a series of meta and para substituted t-butylbenzenes by the chlorine atom at 70°C has been carried out. Application of the Hammett equation yielded a ρ value of -0.44 for the para compounds. Possible explanations for the non-linearity...

Electrochemical Advancement of Solid State Ion Selective Electrodes

Creator:: Bahro, Christopher
Abstract:: The general theme of this dissertation is the development of new analytical sensors to quantitatively study biological and environmental samples in aqueous and non-aqueous environments. A platinum ultramicroelectrode (UME) and a unique carbon-based pH microprobe were used to design a new SECM-based electrochemical bioassay. The Pt UME was used to...

Monolithic sorbents for microscale separations

Creator:: Doneanu, Angela
Abstract:: Over the last decade, the miniaturization of analytical systems has become an increasingly important and interesting research area. Miniaturized systems offer many advantages, including reduced reagent and sample consumption, shorter analysis times, portability and disposability. This dissertation describes novel approaches in this direction, focusing on two areas: the miniaturization of...

Total Synthesis of Tryptamine Alkaloids from the Arundo and Leuconotis Genera

Creator:: Ferreira, Andrew
Abstract:: The first part of this manuscript is about the total synthesis of the Arundo donax bis(indole) natural products. The A. donax alkaloids were prepared using the first example of an ynindole Diels–Alder reaction. Each were then separated, isolated, and determined to have stable enantiomeric conformations at room temperature (Chen, J.;...

Conformationally chiral diphenylethers and the enantioselective Ullmann etherification

Creator:: Salih, M. Quamar
Abstract:: Since the discovery of molecular chirality in 1848, this notion has had a substantial impact on medicine, biology, and chemistry. Extensive effort has been directed towards the construction of chiral molecules that contain sp³ hybridized stereogenic centers. In contrast, less effort has been dedicated to molecules that are chiral by...

The chemical composition of 61 individual Allende chondrules

Creator:: Warren, Richard Gregory
Abstract:: The abundances of 12 elements, Fe, A1, Na, Ni, Cr, Mn, Co, Ca, Sc, Ir, Sm and Eu have been determined by INAA in 61 individual chondrules (0.1-100 mg) separated from five Allende (C3) meteoritic fragments ( 25g). Ti and V have been determined in 18 of these chondrules, and...

A reaction rate determination of aluminum with a microcomputer-based spectrofluorometer

Creator:: Campi, Gregory Louis
Abstract:: The development and optimization of a fluorometric reaction rate method for the determination of aluminum is described. Modifications to existing instrumentation permit automatic monitoring and reporting of measurement conditions. Automatic correction of measured analytical signals is provided if monitored parameters deviate from optimum values. A computer controlled standard addition procedure...
