Chemical and physical influences of the atmosphere upon the spatial and temporal characteristics of atomic fluorescence in laser microprobe plumes

Creator:: Lewis, Arnold Leroy
Abstract:: The temporal and spatial characteristics of the plume produced by a laser microprobe, are dependent upon the composition and pressure of the atmosphere surrounding it. It has been shown that certain atmospheres can enhance the analytical signal by increasing the free atom lifetime. Improvements were made to the existing laser...

Radon-222 as an in situ partitioning tracer for quantifying nonaqueous phase liquid (NAPL) saturations in the subsurface

Creator:: Davis, Brian M.
Abstract:: This study investigated the use of radon-222 as an in situ partitioning tracer for quantifying nonaqueous phase liquid (NAPL) saturations in the subsurface. Laboratory physical aquifer models (PAMs), field experiments, and numerical simulations were used to investigate radon partitioning in static (no-flow) experiments and in single-well, 'push-pull' tests conducted in...

Circular dichroism of amylose and glucose oligosaccharides in the vacuum ultraviolet

Creator:: Lewis, Donald George
Abstract:: The circular dichroism spectra of amylose, the maltose oligomers, cellobiose, and the cycloamyloses are measured in aqueous solution to 1640 A. Two bands are found in this region. The long wavelength band is assigned to the ether chromophores; the short wavelength band is assigned to the hydroxyls and further ether...

Proton-neutron-hole states in antimony isotopes populated in the beta decay of ¹²⁸SN and ¹³⁰SN

Creator:: Nunnelley, Lewis Lee
Abstract:: ¹³⁰ Sn and ¹²⁸Sn were separated from mixed fission products. The decay of these isotopes were studied with Ge(Li), LEPS, and plastic scintillator detector systems in single and two parameter coincidence modes. The decay scheme constructed for ¹²⁸Sn decay has levels at 0.0 (5+), 45.7 (4+), 77.8 (3+), 152.9 (2+),...

The purification and characterization of a ribonuclease from bovine aorta

Creator:: Lewis, Roger Allen
Abstract:: Reports of investigations on nucleases in arterial tissue are few in number. The present study is concerned with the purification and characterization of an aortic ribonuclease. An endonuclease (ARNase I) isolated from the bovine aorta has been purified 4611 fold by means of fractionation with ethanol, acid extraction, isoionic precipitation,...

An investigation of the crystal growth of the heavy metal sulfides in supercritical hydrogen sulfide

Creator:: Lewis, Leroy Crawford
Abstract:: Solubility studies on the heavy metal sulfides in liquid hydrogen sulfide at room temperature were carried out using the isopiestic method. The results were compared with earlier work and with a theoretical result based on Raoult's Law. A relative order for the solubilities of sulfur and the sulfides of tin,...

Preparation and Lewis acid properties of diboron tetrafluoride and related compounds

Creator:: Hansen, John Donald
Abstract:: Attempts to synthesize diboron tetrafluoride by the reduction of boron trifluoride with alkali metal solutions in 1, 2-dimethoxyethane proved to be unsuccessful. No diboron tetrahalide was found when boron trifluoride, antimony trifluoride, or boron trichloride was reacted with tetra-(dimethylamino)-diboron; although there appeared to be some exchange between chloride and amine...

Low temperature thermal analysis of some boron halide complexes with weak Lewis bases

Creator:: Lerch, Ronald Edwin
Abstract:: Thermal analysis was used to investigate the following seven systems: H₂S-B₂F₄, SOF₂-B₂F₄, COC1₂-B₂F₄, SF₄-B₂F₄, Xe-BF₃, NF₃-BF₃, and NF₃-BC1₃. In two of the seven systems compound formation was observed. In the system, H₂S-B₂F₄ the compounds H₂S[superscript .]B₂F₄ and 2H₂S[superscript .]B₂F₄ are formed. The compound H₂S[superscript .]B₂F₄ has a melting point of...
