Laser conditioning and electronic defect measurements of HfO sub 2 and SiO sub 2 thin films

Description: Multilayer HfO{sub 2}/SiO{sub 2} high reflectors (HR) and polarizers show a permanent increase in their 1064-nm damage thresholds following laser conditioning at subthreshold fluences. Threshold increases of 2--3x are typical. In an effort to better understand the conditioning effect we have made laser conditioning and electronic property measurements on single layers of these two materials. The laser damage threshold of 1-{mu}m thick e-beam deposited SiO{sub 2} was increased by laser condition… more

NQR-NMR studies of higher alcohol synthesis Cu-Co catalysts

Description: The primary objective of the project is to examine the relations between the catalytic and magnetic properties of the copper-cobalt higher alcohol synthesis catalysts. We have undertaken to investigate the magnetic character by studying the Nuclear Quadrupole resonance of copper and (Zerofield) Nuclear Magnetic Resonance of cobalt in copper cobalt catalysts.

NQR-NMR studies of higher alcohol synthesis Cu-Co catalysts

Description: Our previous studies (1,2) on the zerofield NMR spectra of Cu/Co catalysts revealed that the method of preparation sensitively influences the magnetic character of the Catalyst. Catalytic studies of the earlier investigators also (3) show similar influence on the product selectivity and indicate reproducible performance is critically dependent on the control and rigor of the preparation technique. To compliment the NMR results, we have made a thorough investigation of the Hysteresis character o… more

Two-dimensional nuclear magnetic resonance of quadrupolar systems

Description: This dissertation describes two-dimensional nuclear magnetic resonance theory and experiments which have been developed to study quadruples in the solid state. The technique of multiple-quantum magic-angle spinning (MQMAS) is extensively reviewed and expanded upon in this thesis. Specifically, MQMAS is first compared with another technique, dynamic-angle spinning (DAS). The similarity between the two techniques allows us to extend much of the DAS work to the MQMAS case. Application of MQMAS to … more

Non-Invasive Diagnostics for Measuring Physical Properties and Processes in High Level Wastes

Description: This research demonstrated the usefulness of tomographic techniques for determining the physical properties of slurry suspensions. Of particular interest was the measurement of the viscosity of suspensions in complex liquids and modeling these. We undertook a long rage program that used two techniques, magnetic resonance imaging and ultrasonic pulsed Doppler velocimetry. Our laboratory originally developed both of these for the measurement of viscosity of complex liquids and suspensions. We hav… more

Malonylation of Glucosylated N-Lauroylethanolamine: A New Pathway That Determines N-Acylethanolamine Metabolic Fate in Plants

Description: This article focuses on the gene At5g39050, which encodes a phenolic glucoside malonyltransferase 1 (PMAT1), to better understand the biological significance of N-lauroylethanolamine (NAE 12:0)-induced gene expression changes.
