  • Copper homogeneity studies in meteorites

    Creator:
    Wong, Dennis Tung
    Abstract:
    The abundance of copper was determined in four to six one-gram specimens separated by a distance of several inches from each of 23 large chondritic fragments (greater than 1 kg) via instrumental neutron activation analysis and counting of the annihilation N-rays of ⁶⁴Cu. It is believed that an accuracy of...

  • Protein synthesis in Sarcophaga bullata

    Creator:
    Allen, Robert Roy
    Abstract:
    An investigation was made into certain aspects of protein synthesis at different developmental stages of the flesh fly Sarcophaga bullata. This included measurements of the incorporation of labeled amino acids into protein by intact cells from a single organ, the larval fat body, and a study of amino acid activating...

  • Functionalization of carbon nanotubes for effective biosensing and potential biomedical applications

    Creator:
    Adenuga, Adeniyi A.
    Abstract:
    Since their discovery in the 1990s, the great potential of carbon nanotubes (CNTs) has made them a focus of many research endeavors, including their application as components of biosensors. The inherent chemical "inertness" of CNTs makes their application to biosensing a challenge. It is necessary to "decorate" their surfaces to...

  • Analytical Platform to Study Bacterial Metabolism and their Interactions with Biomaterials using SECM

    Creator:
    Sheet, Partha S.
    Abstract:
    The microbial communities play a crucial role in maintaining human health and cause diseases through very complex microbial chemical interactions. Therefore, these microbial communities have drawn much attention to the scientific communities. To elucidate these complex microbial communities and the chemical interactions within it, one or more isolated species of...

  • Chronopotentiometry of Sm(II) and Pm(III) in molten LiCl-KCl eutectic

    Creator:
    Nixon, Richard Allen
    Abstract:
    Samarium (III) and promethium (III) were studied by chronopotentiometry in a molten LiCl-KC1 eutectic. Tungsten electrodes were used to avoid alloying effects encountered with platinum electrodes. Adsorption phenomena were observed which prevented the study of any kinetic effects. The quarter wave potentials were measured as: Sm(III) = 0.95 ± 0.05...

  • Alkylation studies on Hagemann's ester: an approach to the synthesis of the trisporic acids

    Creator:
    Sung, Wing Lam
    Abstract:
    Sequential alkylation of Hagemann's ester with methyl and methallyl halides has been studied. Treatment of Hagemann's ester with methyl iodide and sodium ethoxide gave a mixture of 21 and 25 in a ratio of 4:1. Alkylation of 21 with methallyl chloride and potassium t-butoxide afforded a mixture of 37 and...

  • Comprehensive Analysis of The Brain Metabolome Using Mass Spectrometry in Conjunction with Data Analysis Techniques

    Creator:
    Khorani, Mona
    Abstract:
    Metabolomics has recently gained momentum in biomolecule research and complements the genomics and proteomics research space. Metabolomics strives to detect, identify, and quantify all metabolites present in biological samples. In particular, biomolecular analysis using ultra-performance liquid chromatography combined with mass spectrometry (UPLC-MS) has become increasingly important for metabolomic analyses. Similarly,...

  • Total synthesis of sparteine alkaloids from a common tetraoxobispidine intermediate

    Creator:
    Melbardis, John
    Abstract:
    In previous work (Blakemore et al. Org. Lett. 2005, 7, 4721; Heterocycles 2006, 70, 609), successful elaborations of the lupine alkaloids (±)-α-isosparteine (dl-2) and (±)-β-isosparteine (dl-3) were realized from a common tetraoxobispidine precursor, 3,7-diallyl -2,4,6,8-tetraoxo-3,7-diazabicyclo[3.3.1]nonane (93). Herein, the tetraoxobispidine approach to lupine alkaloids was extended to a total synthesis of...

  • Innovative Bioanalytical Tools & Methods for Combinatorial Non-Coding RNA Analysis

    Creator:
    Zhang, Lulu
    Abstract:
    Recently researchers have discovered that groups of small non-coding RNAs (ncRNAs) play regulatory roles in gene expression and participate in various biological processes. For example, pathogenesis of many diseases, cell cycle regulation, and signaling pathways. Intracellular and live cell imaging of small ncRNA groups will reveal their relative expression levels...
