Terahertz (THz) radiation is electromagnetic waves with frequencies ranging roughly from 0.1 to 10 THz, or wavelengths roughly from 0.03 to 3 mm. In recent …
This dissertation discusses two related clinical applications of visible regime diffuse reflectance spectroscopy as well as two new configurations of liquid crystal microspectrometer suitable in …
The characterization of transient molecules formed during chemical processes has been a longstanding challenge because the lifetimes of intermediates are often very short and structural …
Diverse hydrous minerals have been identified on Mars and suggest a rich history of water-rock interactions in a variety of aqueous environments. Fe/Mg clays and …
The primary objective of this thesis is the development of methods to generate and detect local phonons in aqueous solutions, which lead to new understanding …
The rational design of novel inorganic compounds requires a descriptive and quantitative understanding of their solution speciation and electronic structure. This thesis highlights several representative …
The climatic history of Mars has been indirectly studied through the remote detection of minerals produced by chemical alteration across its surface. While the martian …
A suite of lunar materials is examined with reflectance spectroscopy. Reflectance spectroscopy is capable of collecting compositional data for planetary surfaces at high spatial resolution …
Exposure, weathering, transport, deposition, and diagenesis have profound effects on sediment on planetary surfaces and the final, observable geologic record. This thesis constrains the ways …
Water-rock reactions affect the evolution of planetary crusts and largely control their potential for habitability and biosignature preservation. Here we use data from remote sensing …
