Formation, Functionalization, Characterization, And Applications Of A Mixed-Mode, Carbon/Diamond-Based, Core-Shell Phase For High Performance Liquid Chromatography, Landon A. Wiest

Theses and Dissertations

My work has focused on a variety of different types of diamond-based, core-shell particles. These particles are formed with inert cores and poly(allylamine)/nanodiamond shells. Their intended purpose is to form an LC stationary phase that is stable from pH 1 – 14 and at elevated temperatures. At the beginning of my studies, the particles that had been made in the Linford laboratory were pH stable, but irregular and had poor mechanical stability. Since that time, I have worked to improve the particles by using more spherical zirconia and carbon cores, and I have improved their mechanical stability via chemical crosslinking …
