A study of new optical materials I. Crystal-chemical development of new optical frequency converters II. New hosts for Cr3+ luminescence and lasing

Creator:: Schaffers, Kathleen I.
Abstract:: The emphasis of this work has been in two areas of optical materials - the crystal-chemical development of new optical frequency converters and the synthesis and study of new hosts for Cr³⁺ luminescence and lasing. A simple method has been developed to identify promising frequency-doubling materials containing triangular oxoanions by...

Beginning the search for the inverse fission of uranium

Creator:: Beckerman, John R.
Abstract:: The nuclear reaction ¹⁰⁰Mo(¹²⁴Sn,xn)[superscript 224-x]U has been carried out at E[subscript cot] of 578 MeV and 634 MeV using the facilities and equipment at the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory (ORNL) in order to initiate the search for the inverse fission of uranium. Reference...

Graphite intercalation compounds containing fluoroanions

Creator:: Katinonkul, Watcharee
Abstract:: New chemical synthesis strategies have been investigated for the preparation of acceptor-type graphite intercalation compounds (GIC's) with fluoroanions in order to obtain new materials and to develop a better understanding of the synthetic approaches and properties of the products. New GIC's containing borate chelate anion such as bis(oxalato)borate, CxB[OC(O)C(O)O]₂•δF, are...

Analysis of semi-volatile organic contaminants and their accumulation in remote aquatic ecosystems of the western US

Creator:: Ackerman, Luke K.
Abstract:: Many pesticides, polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons are persistent, bio-accumulative, and toxic. These semi-volatile organic compounds (SOCs) can undergo atmospheric transport and deposition in cold, remote ecosystems. A better understanding of their accumulation in the fish of these ecosystems is important to better predict...

Gene Expression, Structure Elucidation, and Bioactivity of Aspergillus Natural Products

Creator:: Neuhaus, George F.
Abstract:: The study of natural products (NPs) and their application has shaped humanity. Starting with the idea of using plants as medicine, it has now grown into the science of purifying and identifying organic molecules from nature to study their inherent biological activities. Understanding the molecular structures of NPs is the...

A study of the limitations of ultraviolet spectral data for the determination of dissociation constants of organic nitrogeneous bases

Creator:: Vachananda, Sookapracha
Abstract:: Ultraviolet spectroscopic methods for the determination of dissociation constants can only be applied to those compounds having protonatable sites conjugated with or inherent in a chromophoric group of the compound. The determination of the dissociation constants of organic nitrogeneous bases by ultraviolet spectroscopic methods was found to be only reliable...

The oxidation of triethylamine by thallium(III) chloride

Creator:: Arneson, Robert Lawrence
Abstract:: The oxidation of triethylamine by the two electron oxidant thallium(III) chloride was studied and the results compared to those when triethylamine is oxidized by copper(II) halides. This study requires anhydrous conditions since in an aqueous system thallium(III) chloride is extensively hydrolyzed and triethylamine causes precipitation of thallium(III) oxide. Most of...

Galvanostatic control of ion selective electrodes with the solvent polymeric membrane

Creator:: Perera, Hasini R.
Abstract:: Detection technique that proposed utilizing electrochemically controlled, reversible ion extraction into polymeric membrane in an alternating galvanostatic/ potentiostatic mode was introduced. This method is studied in detail to comprehend the advantages of the novel sensor (pulstrode) compared to the potentiometric ion selective electrode (ISE), studies included possible applications and limitations....
