Development of novel analytical methods to detect emerging contaminants in aqueous environmental matrices using large-volume injection

Creator:: Backe, Will J.
Abstract:: It is the responsibility of humans, as environmental stewards, to monitor our impact on the environment so that efforts can be made to remediate the effects of our actions and change behaviors. To better understand our environmental footprint, sensitive and simple analytical methods are needed to quantify the contaminants that...

Design, characterization, and application of spectrometers for determination of low-level dissolved oxygen with small-volume sampling methodology

Creator:: Cakin, Defne
Abstract:: New analytical methods and instrumentation were developed for the determination of dissolved oxygen (DO) at low concentrations in water. The methods were based on monitoring the absorbance increase due to the oxidation of reduced indigo carmine (IC) by oxygen in the sample in different types of spectrometer cells. Spectrophotometer cells...

Some biochemical studies of phenylmercuric acetate and mercuric acetate toxicity in rats

Creator:: Ellis, Robert William
Abstract:: Biochemical studies of phenylmercuric acetate (PMA) and mercuric acetate toxicity in rats carried out during this investigation were (1) the metabolism of ²⁰³Hg(Ac)₂ and ²⁰³Hg-PMA within kidney and liver tissues following oral ingestion, (2) the effect on some soluble enzyme activities and determinations of ²⁰³Hg binding in the enzyme fractions,...

Gold Nanostars: Spectroscopic and Physical Properties

Creator:: Zhou, Lixia
Abstract:: Tethering fluorophores on metal nanoparticles for metal enhanced fluorescence (MEF) has attracted a lot of attention from scientists interested in fluorescence based approaches. MEF has many benefits in fluorescence related techniques, because the analytical signal increases and enables potentially lower detection limits or better sensitivity. Many types of nanoparticles have...

Atom abstraction from excoyclic postitons of derivatives of methylated pyridines and quinolines : an evaluation of change separation in the transition states of these reactions

Creator:: Mahiou, Belaid
Abstract:: The relative rates of hydrogen atom abstraction from a series of 13 homoaryl and heteroarylmethanes by the nucleophilic undecyl radical, thermally generated from lauroyl peroxide, were determined at 70 °C. A reactivity range of 15 was obtained. Substantial differences in reactivity among isomers were found. The relative reactivities of the...

Innovative Bioanalytical Tools & Methods for Combinatorial Non-Coding RNA Analysis

Creator:: Zhang, Lulu
Abstract:: Recently researchers have discovered that groups of small non-coding RNAs (ncRNAs) play regulatory roles in gene expression and participate in various biological processes. For example, pathogenesis of many diseases, cell cycle regulation, and signaling pathways. Intracellular and live cell imaging of small ncRNA groups will reveal their relative expression levels...

Tandem intramolecular photocycloaddition-retro-Mannich fragmentation as a route to indole and oxindole

Creator:: Li, Yang
Abstract:: Irradiation of a tryptamine linked through its side-chain nitrogen to an alkylidene malonate residue results in an intramolecular [2 + 2] cycloaddition to the indole 2,3-double bond. The resultant cyclobutane undergoes spontaneous retro-Mannich fission to produce a spiro[indoline-3,3-pyrrolenine] with relative configuration defined by the orientation of substituents in the transient...

Chiral synthesis of monic acid C

Creator:: Theramongkol, Parinya
Abstract:: Bromoalkoxylation of dihydropyran with bromine and 1-borneol, followed by dehydrobromination and epoxidation, afforded trans-2-1- bornyloxy-3,4-epoxytetrahydropyran as a major product. This was treated with sodium phenylselenide to give a 1:1 mixture of (2R,3R,4R)- 2-1-bornyloxy-3-hydroxy-4-phenylselenotetrahydropyran and its (2S,3S, 4S) diastereomer. Elimination of the selenoxide, derived from oxidation of the former with hydrogen...
