Rapid kinetics study of the nuclease activity of RecBCD enzyme from Escherichia coli
(2006-03-31)RecBCD enzyme from Escherichia coli is involved in homologous recombination and repair of bacterial DNA, and in defending the cell against foreign DNA. This enzyme has multiple functions - it is an ATP-stimulated ssDNA ... -
RAPID Lithography: Photopolymerization Characterization and Initiation Kinetics
(2012)In order to improve upon the resolution of photolithography, a technique that is used to produce features for today's micro and nanodevices, techniques must move beyond e-beam and deep-UV sources. Multiphoton absorption ... -
REACTION MECHANISMS AND INTERFACE CHARACTERISTICS OF ELECTRODE AND ELECTROLYTE MATERIALS FOR MAGNESIUM BATTERIES
(2020)Rechargeable magnesium (Mg) batteries are an emerging electrical energy storage technology proposed as an alternative to current Lithium-ion (Li-ion) batteries. Mg batteries have the potential to provide more energy than ... -
Reactions of Zintl ion Pb9 with Gold Precursor PPh3AuCl
(2006-12-10)Transition metal main group clusters have been studied extensively as models for heterogeneous catalysts and metal surface reactions. In this thesis, reactions of Group 14 Zintl ion cluster Pb94- with the Au precursor ... -
The Redox Chemistry of Dirhodium Carboxamidates: From Fundamental Structures to Catalytic Functions.
(2008-03-24)Redox chemistry is the study of molecular structure and function associated with changes in oxidation state. In this manuscript, the structures and functions of dinuclear rhodium complexes in various oxidation states are ... -
REDUCTIVE ELIMINATION OF (DPMS)PTIV COMPLEXES DERIVED FROM ISOMERIC 2-BUTENEs AND 2-BUTYNE (DPMS=DI(2-PYRIDYL)METHANE SULFONATE)
(2012)The (dpms)PtII complexes (dpms = di(2-pyridinyl)methanesulfonate)derived from some cyclic olefins can be readily oxidized to PtIV oxetanes, followed by reductive elimination to produce corresponding epoxides. A catalytic ... -
Release of Aluminum, Arsenic, Cadmium, Chromium, Copper, Iron, Lead, and Zinc in a Coal Leachate, and their Removal from Solution Undergoing Neutralization
(1992)Whole coal contains significant amounts of iron pyrite which is oxidized ultimately to ferric acid sulfate. As a result, trace elements are released from the coal and other minerals in potentially hazardous concentrations. ... -
Remarkable structural transformations of actin bundles are driven by their initial polarity, motor activity, crosslinking, and filament treadmilling
(2019)Bundled actin structures play a key role in maintaining cellular shape, in aiding force transmission to and from extracellular substrates, and in affecting cellular motility. Recent studies have also brought to light new ... -
A Reply to van den Berg and van der Sluys: Effects Resembling a Bio-Field on a Torsion Pendulum Cannot Be Caused by Heated Air Currents Generated by the Subject
(Society of Scientific Exploration, 2015)A Reply to van den Berg and van der Sluys: Effects Resembling a Bio-Field on a Torsion Pendulum Cannot Be Caused by Heated Air Currents Generated by the Subject -
RESOLUTION IMPROVEMENT OF PHOTOLITHOGRAPHIC TECHNIQUES BASED ON VISIBLE LIGHT
(2017)The semiconductor industry is planning to use Extreme Ultraviolet lithography as its next-generation patterning technique. However, this technique has run into many roadblocks due to its cost and complexity. An alternative ... -
Resolution of PM sources using highly time resolved data and discrete particle size bins
(2006-05-26)The goal of this project was to explore the use of particle size distribution data for distinguishing between local vs distant and controlled vs uncontrolled combustion sources. A two day period in July was selected for ... -
REVEALING THE STRUCTURAL AND FUNCTIONAL PROPERTIES OF NON-CANONICAL K6-LINKED POLYUBIQUITIN CHAINS.
(2017)Ubiquitin is an important protein modifier in eukaryotes, which tags the proteins and signals them to different pathways in the cell. It has been shown that polyubiquitin chains of different linkages act as distinct cellular ... -
REVERSIBLE QUINONE METHIDE ALKYLATION OF DNA
(2009)Alkylation of DNA has been found to cause cancer and also to serve as its treatment. Quinone methides (QMs) are highly electrophilic molecules implicated in numerous metabolism processes. Studies of QM's reversible ... -
