Electronic Theses and Dissertations
Layer by layer (LbL) self assembly is a simple multilayer thin (nanometer scale) film fabricating technique. The mechanism of film growth remains a topic of much controversy. For example, several models have been proposed to explain the origin of linear and exponential film growth that are attributed to differences in the dynamic processes that occur at the molecular level during film formation. The problem is that there are no methods that directly measure the dynamics of polymer formation during LbL film formation. In this thesis, I describe the essential elements of an ATR-IR spectroscopic method that was developed to enable …

The goal of our work is to provide marine scientists with a detection system which can be mounted on buoys and gliders for measuring the amount of iron (III) in sea water. Iron is the limiting nutrient for phytoplankton growth. Since phytoplankton play a key role in global carbon cycles and global warming, the iron in seawater does as well. This thesis is meant to be a proof-of-concept for a new approach to measuring iron in seawater. The essential elements of the research discussed herein include identifying particulate beads which are optically transparent in the visible region, modifying the surfaces …
