The solution chemistry and kinetic behavior of hafnium peroxy sulfate solutions ("HafSOx") is described in terms of peroxide content and solution speciation. Additionally, thin film behavior, including thermal behavior and solubility, is characterized, and a mechanism of patterning is presented, as well as parameters that should be considered when looking...
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...
A survey of the methods of purification of KC1, for use in
preparing single crystals by growth from the melt, was made. Two
methods, fractional recrystallization and ion exchange, were used.
The purity of the salt and crystals grown from the same salt were
compared with the findings of other...
We have developed a compact micro total analysis system (μTAS) to serve as a platform for in-situ spectrophotometric water quality monitoring. Individual fluidic, optical, and electrical components were designed, developed, and characterized. These components were combined in both an integrated (single lithographic “chip-based” platform) and a modular manner. The microfluidic...
A three part study involving aspects of radical properties of various
aromatic species was accomplished.
Experiments to ascertain the importance of geometric and electronic
effects on the intramolecular transfer of a pi-complexed radical to a terminal double bond
was performed. Several 4-aryl-1-butenes were reacted in competition with 1-undecene
with a...
