Carbon Nanotube Growth Via Spray Pyrolysis, Robert Welch Call
Undergraduate Honors Capstone Projects
Spray pyrolysis is a promising method to create carbon nanotube forests (CNFs) on various surfaces. By injecting metallocene-hydrocarbon solutions into a heated quartz reactor, catalyst particles and carbon nanotubes can be formed simultaneously. Factors that affect CNF growth include the precursor concentration, injection rate and duration, carrier gas flow rate, substrate surface, growth temperature, and the composition of gases inside the reactor. The CNF morphologies affected by these factors will be presented and, hopefully, an optimum condition will be found.

Lidar User’S Manual, Lance William Peterson
Undergraduate Honors Capstone Projects
This is intended to be a user’s manual for the upgraded USU Rayleigh lidar. As such, it begins with a discussion of the purpose of a lidar. This is followed by a brief explanation of the fundamentals of Rayleigh scatter lidar. Next the reasons for and benefits of upgrading the lidar are discussed and as well as how the upgrade was accomplished. After establishing this basis, instructions are provided for operating the lidar, performing basic maintenance, and aligning various components.
