A microcomputer automated anodic stripping voltammetric analyzer for trace heavy metal speciation

Creator:: Dewald, Lamar Robert
Abstract:: An automated instrument based on a single-board microcomputer was developed for use in voltammetric analyses. Operator input of numerous experiment parameters allows any type of voltammetric analysis to be implemented and multiple scans to be run unattended. A three operational amplifier potentiostat is used to control the cell voltage and...

Zero Kinetic Energy Photoelectron Spectroscopy of Polycyclic Aromatic Hydrocarbons

Creator:: Harthcock, Colin
Abstract:: In this dissertation, I describe spectroscopic studies of jet-cooled polycyclic aromatic hydrocarbons (PAH) and one nitrogen substituted PAH (PANH) using pulsed field zero kinetic energy (ZEKE) photoelectron spectroscopy and resonantly enhanced multiphoton ionization (REMPI) spectroscopy. Recently, there has been a demand for far-infrared (FIR) spectral information of astrophysically relevant molecules...

Design and application of a microcomputer automated multielement flame atomic fluorescence instrument

Creator:: Neyzari, Shahrokh Ghaffari
Abstract:: An automated multielement flame atomic fluorescence (AF) spectrometer based on microcomputer control was constructed to determine four elements simultaneously. The instrument employs a multiple exit slit monochromator where the light from various exit slits is directed to a single detector with a mirrored funnel. Each element is excited to fluoresce...

Expediting the Generation and Analysis of Amorphous Oxide Computational Models: Modeling Complex Systems Swiftly

Creator:: Buchanan, Jacob C.
Abstract:: In this dissertation, the process of computational modeling of amorphous oxide materials is studied. Amorphous oxides have random atomic arrangements with no long-range structural order which makes it difficult to study structure-property relationships. Despite the difficulties, amorphous oxides have great uses as semiconductors and dielectrics in thin-film transistors. The ability...

Coherent anti-Stokes Raman spectroscopy of gases

Creator:: Guthals, Dennis Marc
Abstract:: The development and applications of a 0.2 cm⁻¹ resolution Nd-YAG laser powered coherent anti-Stokes Raman spectroscopy, CARS, spectrometer for gas phase studies is chronicled in this thesis. Applications including CARS lineshape analysis, resonant CARS, and CARS of transient species and excited state molecules is reported. The intensity of the signal...

Syntheses and structures of new inorganic borates

Creator:: Sun, Hongxing
Abstract:: Several new solid-state inorganic borates have been prepared and characterized. Single crystals of the simple orthoborate ScB0₃ were grown and its structure was determined by single-crystal X-ray methods. The new borates Li₃Sc(B0₃)₂, LaSc₃(B0₃)₄, NdSc₃(B0₃)₄, SrNaB0₃, and Li4Ln4MB90₂₃ (Ln = Y, Er, and Gd; M = Al and Ga) were identified...

Development of trace enrichment techniques for trace metals in natural waters using high pressure liquid chromatography

Creator:: Ambrose, Arthur Sigurd
Abstract:: An on-line trace enrichment (TE) system, based on high pressure liquid chromatogroaphy (HPLC) and flame atomic absorption (AA), has been developed for trace metal analysis. The sample is pumped through a column filled with a cation exchange resin which traps metal ions. The ions are subsequently stripped from the column...
