Molecular Structure and Surface Organization: A Study of Liquid/Vapor Interfaces Using Newly Developed Sum Frequency Methods
Vibrational sum frequency spectroscopy (VSFS) is a surface specific nonlinear technique that provides vibrational spectra of molecules at interfaces. Studies presented in this thesis use VSFS to examine surface structure ...
AQUEOUS PHOTOCHEMISTRY OF 1,4-BENZOQUINONES AND THEIR POSSIBLE ROLE IN THE PHOTOCHEMISTRY OF NATURAL ORGANIC MATTER
Past research implicated the presence of an organic species as a photochemical source of OH radical in natural waters. Quinones were postulated to be one of the possible OH sources due to 1) the ubiquitous occurence of ...
Synthesis, Characterization and Catalytic Properties of Bimetallic Nanoparticles
Due to the ever-increasing desire for catalysts that possess high activities and selectivities for industrially relevant reactions, much effort is being spent on the synthesis of mono and bimetallic nanoparticles with ...
SOLVENT BEHAVIOR IN HYDROPHOBIC SILICA NANOTUBES AND NANOTUBE MEMBRANES
The development of template-synthesized silica nanotubes has created a unique opportunity for studying confined fluids by providing nanometer-scale containers in which, the inner diameter (i.d.) and surface chemistry can ...
THE OPTICAL KERR EFFECT OF LIQUIDS
Optical Kerr effect (OKE) spectroscopy has found broad use in monitoring ultrafast dynamics in transparent media. I demonstrated that by using two pump pulses with independently-controllable polarizations, intensity and ...
