Development and application of an analytical technique for the determination of methylmercury compounds in environmental samples based on isolation by distillation, followed by purge-and-trap sample concentration and GC/MS separation and detection, after aqueous phase ethylation with sodium tetraethylborate

Creator:: Rice, William R.
Abstract:: An analytical technique has been developed for the determination of methylmercury compounds in environmental samples. The technique is based on a two-stage procedure. In the first stage, methylmercury compounds are isolated from the sample matrix as methylmercury chloride (MeRgCl) by distillation. The distillation procedure is based on a series of...

Designing Dielectric Materials through Complex Metal Oxides

Creator:: Nikkel, Jason W.
Abstract:: This dissertation demonstrated that the electrical properties of complex oxide-based perovskite materials could be controlled through the careful modification of both material composition and structure. This was first shown through the modification of lead zirconate titanate (Pb(Zr0.52Ti0.48)O3, PZT) solid solutions with bismuth indate (BiInO3, BI) where the relative stability of...

Direct patterning of solution deposited metal oxides

Creator:: Stowers, Jason K.
Abstract:: Patterning of metal oxides typically involves a multi step process, involving depositing a resist, patterning that resist with some form of lithography, etching the oxide through the resist, and finally removing. This process can be simplified if the resist is removed and replaced with a metal oxide that can be...

Flame ionization detection of hydrocyanic acid ; Analysis of trace aqueous solutions

Creator:: Claeys, Robert Raymond
Abstract:: A gas chromatographic procedure was developed for the determination of nanogram quantities of hydrocyanic acid using a flame ionization detector. Excellent chromatograms were obtained on a porous polyaromatic polymer column (Porapak Q) at 60°C. The procedure was employed for the analysis of HCN in aqueous cyanide solutions. Solutions as low...

Abiotic and biological transformation of TBOS and TKEBS, and their role in the biological transformation of TCE and c-DCE

Creator:: Vancheeswaran, Sanjay
Abstract:: At Site-300, Lawrence Livermore National Laboratory (LLNL), CA, trichloroethene (TCE) is present along with tetraalkoxysilanes such as tetrabutoxysilane (TBOS) and tetrakis(2-ethylbutoxy) silane (TKEBS), as subsurface contaminants. Intrinsic transformation of TCE to cis-dichloroethene (c-DCE) was observed in the groundwater at locations co-contaminated with TBOS or TKEBS. Attenuation of TBOS and TKEBS...

Optical diffraction study of ultrasonic sound velocity in nitrous oxide and ammonia gases

Creator:: Strauch, Joseph George
Abstract:: The velocity of sound in gases was measured, using an ultrasonic wave train as a diffraction grating. The fundamental problems involved in the optical technique are discussed. An apparatus utilizing an objective lens of focal length 1.5 m and aperture f/20 was constructed and used at an ultrasonic frequency close...

Cold vapor atomic absorption and fluorescence analysis of mercury

Creator:: Hawley, James Edward
Abstract:: A critical study of the cold vapor atomic absorption and fluorescence instrumentation for the analysis of mercury is described. Some of the important modifications involve the reduction vessel, absorption cell, fluorescence cell, and radiation source. The new modified systems have much greater calibration sensitivities and lower detection limits than those...
