Chemical element profiles by instrumental neutron activation analysis : in, part 1, two species of wheat bunt spores, Tilletia caries (DC) Tul. and Tilletia controversa Kühn; part 2, representative sediment and basalt samples taken from a DSDP 678 m core, site 525A, Leg 74, Walvis Ridge

Creator:: Liu, Yun-gang
Abstract:: Part 1 The concentration of seventeen elements in two species of fungus which cause wheat bunt disease, Tilletia caries (DC.)Tul. (TS) and Tilletia controversa Kiihn (DS), were determined by instrumental neutron activation analysis in 37 TS spore samples, and 31 DS spore samples. Aluminum was chosen as a soil contamination...

Fate and transport of the surfactant linear alkylbenzenesulfonate in a sewage-contaminated aquifer

Creator:: Krueger, Carolyn J.
Abstract:: Linear alkylbenzenesulfonate (LAS) is the most widely used anionic surfactant in commercial detergent formulations. The environmental fate of LAS is of interest because of its disposal to wastewater treatment facilities and subsequent occurrence as a micropollutant in surface waters and groundwater. While LAS fate in wastewater treatment systems and surface...

Development of novel analytical methods to detect emerging contaminants in aqueous environmental matrices using large-volume injection

Creator:: Backe, Will J.
Abstract:: It is the responsibility of humans, as environmental stewards, to monitor our impact on the environment so that efforts can be made to remediate the effects of our actions and change behaviors. To better understand our environmental footprint, sensitive and simple analytical methods are needed to quantify the contaminants that...

Structure-property relationships in oxides containing select platinum group metals

Creator:: Gatimu, Alvin J.
Abstract:: Oxide materials exhibit a wide variety of structures and properties. In particular, transition metal oxides tend to be highly stable while exhibiting a wide range of properties that can be used for numerous applications. This work focuses on investigating how the structures’ of 4d and 5d transition metal oxides influences...

Chemical and statistical analyses of chondrules from the Mokoia (CV3) meteorite

Creator:: Schilk, Alan J.
Abstract:: Nearly 100 chondrules were extracted from -8.6g of the Mokoia (CV3) meteorite and have been analyzed by sequential instrumental neutron activation analysis (INAA). The resulting data were utilized in a comprehensive statistical characterization of these objects and, unlike similar investigations, virtually no loss of relevant data was incurred due to...

Measuring in situ reductive dechlorination rates in trichloroethene-contaminated groundwater

Creator:: Hageman, Kimberly J.
Abstract:: Trichloroethene (TCE) is the most frequently detected organic contaminant in groundwater, is classified as a probable human carcinogen, and exhibits toxicological effects on the human endocrine, immune, developmental, and reproductive systems. While significant research efforts have been devoted to the development of strategies for remediating TCE-contaminated groundwater, their advancement is...

Per- and Polyfluoroalkyl Substances (PFAS) in Environmental Air-Water Matrices and Light Non-Aqueous Phase Liquids (LNAPL)

Creator:: Schwichtenberg, Trever J.
Abstract:: The presence of per- and polyfluoroalkyl substances (PFAS), organic contaminants first synthesized in the 1940s, has been reported worldwide in a variety of environmental matrices and ultimately in biological systems including humans. Ongoing research into PFAS has included identifying novel PFAS, assessing their fate and transport in the environment, and...

Photoresist and ion-exchange chemistry of HafSOx

Creator:: Telecky, Alan J.
Abstract:: The chemistry of hafnium oxide based and materials are described in the context of ion exchange and lithography. HafSOx, represented by the composition HfO₂₋[subscript x](SO₄)x, is described to possess a significant capacity towards ion exchange in acidic and basic solutions, enabling films of HafSOx to be cleanly and readily be...

Natural and semi-synthetic compounds with biocidal activity against arthropods of public health importance

Creator:: Khasawneh, Mohammad A.
Abstract:: This study identified new compounds with pest control activities. The two sources of candidates that were followed here were the main heartwood extract of Alaska Yellow Cedar (AYC) constituents and several semi-synthetic counterparts. Five compounds were isolated and identified for the first time in AYC heartwood in this research: two...

Analysis of fourteen trace elements in Saudi Arabian layered gabbros by radiochemical neutron activation analysis

Creator:: Palmer, Curtis Allyn
Abstract:: Eight layered gabbro samples from two layered complexes, two xenoliths, one basalt from a hot brine area and a standard basalt rock (BCR-1) were analyzed by RNAA (radiochemical neutron activation analysis) for 14 trace elements, Au, Ni, Co, Ag, Sb, Se, Zn, In, T1, Rb, Cs, U, Ba and Sr....
