The Honors project is potentially the most valuable component of an Honors education. Typically Honors students choose to do their projects in their area of study, but some will pick a topic of interest unrelated to their major.
The Honors Program requires that the project be presented at a poster presentation event. Poster presentations are held each semester. Most students present during their senior year, but may do so earlier if their honors project has been completed.
This site presents project descriptions and selected posters for Honors projects completed since the Fall 2015 semester.

Abstract
Hafnia nanocrystals which exhibit one dimensional growth are synthesized via a sol-gel reaction, and the effects of time, temperature, and ligand selection are measured and utilized to control nanocrystal shape and size. Here we report the yield, phase, and a detailed procedure for their synthesis, as well as a kinetic model of growth that fits a simple exponential trend, from which an activation energy can be obtained. Additionally, we propose a crystallization and growth mechanism wherein an amorphous precursor network is formed in solution from the starting compounds, and is crystallized at the reaction temperature by a crystallization agent.
