Performance And Characterization Of A Large Format Solid State Imager, Jacob A. Mendez

Electrical and Computer Engineering ETDs

The purpose of this thesis is to validate the specifications of the CCD 486 as specified by Fairchild Imaging, the manufacturer of the CCD and Spectral Instruments, the manufacturer of the camera control electronics and supporting hardware. Specifications have been provided by both companies and are shown in Appendix A. This study is necessary because of the nature of the experiments to be analyzed using the CCD 486. In addition, the thesis will propose new testing methods for electronically shuttered CCD imagers that are not well understood.

Suppression Of Spontaneous Genome Rearrangements In Yeast Dna Helicase Mutants, Kristina H. Schmidt, Richard D. Kolodner

Molecular Biosciences Faculty Publications

Saccharomyces cerevisiae mutants lacking two of the three DNA helicases Sgs1, Srs2, and Rrm3 exhibit slow growth that is suppressed by disrupting homologous recombination. Cells lacking Sgs1 and Rrm3 accumulate gross-chromosomal rearrangements (GCRs) that are suppressed by the DNA damage checkpoint and by homologous recombination-defective mutations. In contrast, rrm3, srs2, and srs2 rrm3 mutants have wild-type GCR rates. GCR types in helicase double mutants include telomere additions, translocations, and broken DNAs healed by a complex process of hairpin-mediated inversion. Spontaneous activation of the RadS3 checkpoint kinase in the rrm3 mutant depends on the Mec3/Rad24 DNA damage sensors and results from …

Preparation And Electrochemical Characterization Of Anatase Tio2 Nanotubes, Bin Cao, Jin-Wei Xu, Ling-Hong Ding, Wei-Feng Zhang

Journal of Electrochemistry

Titanium oxide nanotubes were prepared by hydrothermal treatment of anatase-type TiO₂ powders and NaOH solution in an autoclave.Transmission Electron Microscopy and X-ray Diffraction showed that the product is anatase-type TiO₂ nanotubes.The constant charge-discharge current and cyclic voltammetry exhibited the TiO₂ nanotubes have a large initial lithium insertion capacity of 260 mA·h/g and good reversibility.This study indicates that TiO₂ nanotubes might be a good negative electrode materical for second lithium battery in the future.

Electrochemical Behavior Of Tanshinoneⅱa And Its Determination, Guang-Wen Li, Xin-Hua Lin, Xiao-Yan Lin

Journal of Electrochemistry

The electrochemical behavior of TanshinoneⅡA was investigated by voltammetry at a glassy carbon electrode.And Differential Pulse Voltammetric method for determination of TanshinoneⅡA was developed.In pH 4.0 acetate buffer solution,the relationship between oxidation peak current of Differential Pulse Voltammetric and the concentration of Tanshinone ⅡA was linear in the range of 3.0×10^-7～2.0×10^–5 mol·L^-1.The detection limit had been estimated as 2.0×10^-8 mol·L^-1.The interference of other components in the preparation could be efficiently eliminated by the glassy carbon electrode.This method can be used for the determination of TanshinoneⅡA in real sample with satisfactory results.

Novel Electrochemical Method For Synthesis Of Nanostructured Materials Of Noble Metals Based On Poly(N-Vinylpyrrolidone) (Pvp), Wei Pan, Xiao-Kai Zhang, Ming-Hu Huang, Shao-Xin Huang, Xing-Li Feng, Hou-Yi Ma

Journal of Electrochemistry

Gold nanocrystals with controllable size were synthesized through a simple electroreduction method using poly(N-vinylpyrrolidone)(PVP) of different polymerization degree as both stabilizer and shape-controller for gold nanoclusters.Individual gold nanoparticles spontaneously assembled into the wire-and ring-shaped nanoparticle aggregates depending on the PVP's dynamic stretching and curling,and precursor nanoparticles grew into flat,single-crystalline nanoprisms with thickness of dozens of nanometers based on the oriented aggregation between particles.Besides,core-shell Au/Ag nanoparticles were conveniently synthesized through two-step electroreduction of noble metal ions in the presence of PVPK30.The electrochemical synthetic method based on PVP provides a new path for preparation of noble metal nanostructured materials with different shape …

Phase-Transfer Technique For Polymer-Protected Noble Metal Nanoparticles, Xing-Li Feng, Ming-Hui Huang, Xiao-Kai Zhang, Shao-Xin Huang, Wei Pan, Hou-Yi Ma

Journal of Electrochemistry

A novel phase-transfer method was developed based on the decrease of PVP's solubility in water with increasing temperature,by means of which PVP-protected gold,silver and platinum nanoparticles can be conveniently transferred from aqueous phase to 1-butanol phase.Monodispersed metal nanoparticles were electrochemically synthesized at first in the aqueous,and then 1-butanol of appropriate volume was added to the aqueous phase.Heating the oil-water mixture to 80 ℃ under vigorous stirring would make metal nanoparticles leave the aqueous phase and enter into the 1-butanol phase,with high phasetransfer efficiency and without aggregation between nanoparticles.An electrochemical method to synthesize metal nanoparticles in the oil-water mixtures was further …

Study Of The Electrooxidation Of Glycerol On Oxide And Pd/C Composite Catalysts, Zhi-Yuan Yan, Chang-Wei Xu, Pei-Kang Shen

Journal of Electrochemistry

Oxide and Pd on carbon composite catalysts have been prepared by intermittent microwave heating(IMH) method.The performance of the catalysts for glycerol oxidation in alkaline solution is studied by electrochemical techniques.It is shown that the Pd/C catalyst is active for glycerol electrooxidation.However,the oxide-Pd/C catalysts are even better in terms of the onset potential that is more negative and peak current density.The ratio of oxide to Pd is optimized according to the electrochemical measurement.The results reveal that the addition of oxide into the Pd/C induces the synergistic effect for glycerol electrooxidation.

Deposition Of Metallic Nanoparticles On Carbon Nanotubes Via A Fast Evaporation Process, Guoqiang Ren, Yangchuan Xing

Chemical and Biochemical Engineering Faculty Research & Creative Works

A new technique was developed for the deposition of colloidal metal nanoparticles on carbon nanotubes. It involves fast evaporation of a suspension containing sonochemically functionalized carbon nanotubes and colloidal nanoparticles. It was demonstrated that metallic nanoparticles with different sizes and concentrations can be deposited on the carbon nanotubes with only a few agglomerates. the technique does not seem to be limited by what the nanoparticles are, and therefore would be applicable to the deposition of other nanoparticles on carbon nanotubes. PtPd and CoPt3 alloy nanoparticles were used to demonstrate the deposition process. It was found that the surfactants used to …

Current And Historical Aquatic Food Webs Of The Middle Rio Grande, Nm, Melanie S. Edwards

Biology ETDs

The Rio Grande has been identified as one of the most endangered rivers in the United States by American Rivers. Biologically, the consequences of the massive anthropogenic alterations of this river have been substantial. The overall aim of this study was to characterize the ecological implications of these alterations in the aquatic food web of the middle Rio Grande (MRG) of New Mexico. Our approach was to analyze the stable isotope composition of current food web components and of historical museum preserved fish specimens. After determining that we could use stable isotope analyses of historical museum preserved fish specimens (chapter …

A Parallel Unmixing Algorithm For Hyperspectral Images, Stefan A. Robila, Lukasz G. Maciak

Department of Computer Science Faculty Scholarship and Creative Works

We present a new algorithm for feature extraction in hyperspectral images based on source separation and parallel computing. In source separation, given a linear mixture of sources, the goal is to recover the components by producing an unmixing matrix. In hyperspectral imagery, the mixing transform and the separated components can be associated with endmembers and their abundances. Source separation based methods have been employed for target detection and classification of hyperspectral images. However, these methods usually involve restrictive conditions on the nature of the results such as orthogonality (in Principal Component Analysis - PCA and Orthogonal Subspace Projection - OSP) …
