Synthesis of nitrogen heterocycles via transition metal catalyzed reductive cyclizations of nitroaromatics.
(2003)
This research focuses on applying a catalyst system discovered in this laboratory, for the intermolecular allylic amination of alkenes with nitrobenzenes, to the synthesis of nitrogen heterocycles via an intramolecular ...
Selective methods for the synthesis of highly-substituted cyclopentadienyl and indenyl ligands.
(2003)
Annulation methods involving cyclization of five-membered rings are regioselective approaches to highly substituted indenyl and cyclopentadienyl ligands for use in metallocene catalysts. The object of our research has been ...
Characterization of crystalline and amorphous phases in poly(N-methylethylenimine) polymer electrolytes and model systems.
(2003)
LPEI is analogous to PEO, except LPEI has a heteroatom that is synthetically versatile because different side groups can be readily attached. LPEI:salt systems are not well understood as polymer electrolytes. Therefore, ...
Unique ansa-bis(indenyl)metallocene dichlorides: The quest for catalysts.
(2003)
The background, methodology, design, and synthesis of these four metallocenes will be discussed. In addition, other less successful attempts will be discussed as regards limits to this new methodology.
A comparison of the standard DNA shotgun sequencing approach and the exponential DNA amplification method for sequencing BAC, fosmid, plasmid, and mitochondrial DNA.
(2003)
Therefore, during the initial phase of my studies, I became well versed in the standard shotgun sequencing techniques and completed the sequence of six regions of the human and mouse genome totaling over 1 Mbp. Then, because ...
Identification and analysis of the response regulator binding site on the surface of the histidine-containing phosphotransfer protein YPD1 from Saccharomyces cerevisiae.
(2003)
The results from the yeast two-hybrid screens were confirmed by the X-ray crystal structure of the SLN1-R1/YPD1 complex. This structure is the first to reveal protein-protein interactions between a monomeric HPt domain and ...
Neurochemical and immunohistochemical effects induced by the 1-methyl-4-phenylpyridinium animal model of Parkinson's disease: An in vivo microdialysis investigation in freely moving rats.
(2003)
Parkinson's disease (PD) is a neurodegenerative disorder which afflicts more than 1 million Americans with an estimated 50,000 new diagnoses each year. 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) causes parkinsonian ...
Computational studies of polymer electrolyte complexes by molecular dynamics and molecular vibrations by principal component analysis.
(2003)
The second part (Chapter 4 and 5) focuses on computing vibrational frequencies and modes by using a new technique, principal component analysis (PCA) which is broadly used in signal processing, pattern recognition, and ...
