Abstract
To better interpret diffuse reflectance spectral data acquired from the Martian surface via remote sensing and surface explorations, a new approach was introduced to identify spectral features of hydrous ferrous sulfates. Through D2O substitution, peaks due to water vibrational modes experienced a shift to lower wave numbers, enabling better identification of pure water overtone and combinational peaks. Estimated peak positions were calculated based on mid-IR and Raman data from hydrated and deuterated samples produced in the lab. The results confirmed that diffuse reflectance spectra are dominated by water vibrational modes and showed that certain spectral features are structure-dependent.
Mike Jin is 17 years old, and he is a junior at John Burroughs High School. Mike finished taking first- and second-semester calculus as a high school freshman, and this spring semester he is finishing Calculus III at Washington University after successfully completing a Differential Equations course at St. Louis University in the winter of 2007. He was invited to take the USA Mathematical Olympiad as a sophomore, and he has assisted with and conducted research at Washington University under many different advisors for the last 3 summers, co-authoring several publications. Mike was also the recipient of the Solutia Award for Excellence in Research for his paper entitled "Temperature-Programmed Multi-Pulse Adsorption", which proposed a method and model for determining various properties of catalyzed reactions, including the concentration of active sites of the catalyst. In college Mike plans to enter business, math, or a field of science, with applied math in economics, chemical engineering, or molecular biology as possible majors.
