Abstract
This paper is a summary of two different research projects that spanned
the summer and fall of 2009: one project investigating the effects of sonication,
pH, and magnetic field on suspensions of graphene oxide, and another
project observing the pre-transitional dynamics in the chromonic liquid crystal
called Bordeaux dye. Though the materials studied in each project were
completely different, both were analyzed using static and dynamic light scattering
techniques. In this paper, we present the results of both experiments
in conjunction with a shared theoretical section on light scattering.
