Synthesis and study of transparent p- and n-type semiconductors and luminescent materials

Creator:: Park, Cheol-Hee
Abstract:: New transparent p- and n-type semiconductors and luminescent materials have been prepared and characterized. Synthesis, structures, optical and electrical properties of new chalcogenide fluoride p-type transparent semiconductors MCuQF (M=Ba, Sr; Q=S, Se, Te) are described. Band-gap tuning and improvement in conductivity through p-type doping are demonstrated in the family. The...

Rhenium-catalyzed oxygen-atom transfer reactions : mechanism and applications

Creator:: Brown, Eric C.
Abstract:: In situ reduction of hydrido-tris-(3,5-dimethylpyrazolyl)borato(trioxo) rhenium(V) with triphenylphosphine or triethylphosphite leads to a reactive rhenium(V) species that catalytically deoxygenates epoxides at 75-105°C. The reaction is stereospecific, except for trans- and cis-butene oxide which formed minor amounts of the opposite isomer. A variety of different functional groups were tolerated and even...

Investigation of the structural influence on the properties of functional inorganic oxides

Creator:: Laurita-Plankis, Geneva
Abstract:: While properties are extremely important from an application point of view, it is crucial to have a detailed understanding of the underlying structural influence. Once a concrete correlation between the structure and the observed property is established, rational design of novel materials with optimized properties can be realized. These optimized...

Studies toward the total synthesis of (+)-providencin

Creator:: Jana, Somnath
Abstract:: Studies toward the total synthesis of (+)-providencin (1), a highly oxygenated cembranoid dipterpene with a unique bicyclo[12.2.0]hexadecane skeleton and pronounced biological activity, are described. These studies resulted in the synthesis of advanced intermediates 320 and 332 which contain all of the carbon atoms of 1. In a first generation approach...

Formation of alkyl-and dialkylcarbenes. The 3-cyclohexenyl carbinyl carbene system

Creator:: Crouse, Dale McClish
Abstract:: The 3-cyclohexenyl carbinyl carbene species was formed by the thermal decomposition of the p-toluenesulfonylhydrazone sodium salt and by oxidation of the hydrazone. Several oxidizing agents were studied. The products were investigated under aprotic and protic conditions and at various temperatures. The diazocompound was formed as an intermediate and found to...

The atmospheric chemistry of particulate-bound polycyclic aromatic hydrocarbons : concentration, prediction, laboratory studies, and mutagenicity

Creator:: Jariyasopit, Narumol
Abstract:: The trans-Pacific atmospheric transport of particulate matter (PM)-bound polycyclic aromatic hydrocarbons (PAHs) to remote sites in western North America has been well documented and has triggered research questions regarding to atmospheric transformation of PM-bound PAHs and the potential impacts on human health from their inhalation exposure. In this dissertation, field...

Tuning Functional Properties of Pyrochlore and Related Oxides via Cation and Anion Substitutions

Creator:: Giampaoli, Gabriella C. S.
Abstract:: Inorganic structures play an important role in materials due to their versatility and diversity. A complete understanding of the structure of a material is vital to enhance the creation of new materials that fill voids in research. The rational design of these compounds is driven by the exploitation of structure-property...
