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...

A study of the chemical composition of Ca-Al-rich inclusions from the Allende Meteorite

Creator:: Conard, Roberta
Abstract:: Nine Ca-Al-rich inclusions and one olivine inclusion from Allende meteorite were studied for Ti, Al, Fe, Mg, Ca, Na, Cl, K, Sc, V, Cr, Mn, Co, Ni, Zn,Hf, W, Ir, Au, Ta, and Re -via INAA (instrumental neutron activation analysis) and REE, Ba, Sr via RNAA (radiochemical NAA). The inclusions...

Absolute stereochemistry and total synthesis of botryococcene

Creator:: Reddy, Guvvala Nagabhushana
Abstract:: Studies were carried out to determine the absolute stereochemistry of botryococcene (1). The natural product was degraded to two sets of 'y- and 8- valerolactones. All enantiomeric variations of these lactones were synthesized in optically pure form starting from (S)- and (R)-methyloxiranes. 1H NMR correlation of natural and synthetic materials...

An approach toward the synthesis of euonyminol and cathedulin K- 19

Creator:: Shin, Hyunik
Abstract:: A synthetic approach toward the two major fragments of cathedulin K-19, euonyminol (4) and dimethyl cathate (69), was investigated. Synthesis of dimethyl cathate was accomplished in 3 steps starting from 73. Efforts directed towards the synthesis of euonyminol, a highly oxygenated dihydroagarofuran sesquiterpene, was advanced to a stage in which...

Approaches to the total synthesis of verrucarol

Creator:: Hill, David E. (David Edwin) 1954-
Abstract:: Verrucarol is the sesquiterpene portion of a number of macrocyclic di- and triesters of potential medicinal importance. In this study, a novel approach to the synthesis of this fungal metabolite is presented. An A-B-C route was investigated in which C-3 and C-4 of the C-ring were emplaced using a [2+2]...

Bridging the Gap Between Equilibrium Properties and Ultrafast Dynamics with Time-Resolved Spectroscopy of Functional Systems

Creator:: Krueger, Taylor D.
Abstract:: Ultrafast spectroscopy has recently gained momentum as a powerful, noninvasive characterization toolset capable of studying a diverse array of samples with applications in chemistry, physics, biology, engineering, and more. Two popular ultrafast spectroscopic techniques include femtosecond transient absorption (fs-TA) and femtosecond stimulated Raman spectroscopy (FSRS). The latter of these techniques...

Chemical composition studies of Oregon and Washington coastal basalts

Creator:: Hill, Dale Wayne
Abstract:: Basalts of both Eocene and Miocene age from several groups along the Oregon and Washington coasts have been analyzed for some major, minor, and trace elements using instrumental neutron activation analysis (INAA). The rare earth element (REE) patterns observed in these samples are used for comparisons within the groups studied...
