  • Electrospray Deposition of Discrete Nanoparticles: Studies on Pulsed-Field Electrospray and Analytical Applications

    Creator:
    Kremer, Matthew H.
    Abstract:
    Electrospinning and electrospray are both nano-scale material fabrication techniques, based on related phenomena of electrically charged fluid spray from a droplet of liquid. Material is dissolved in liquid, then a spray is generated by applying a high voltage, creating an electric field, between the fluid dispensing capillary and a grounded...

  • Improvements in synthesis and response techniques of ion-selective sensors

    Creator:
    Pylypiuk, Nataliia
    Abstract:
    Two improvements to the established procedures for synthesis and response detection of ion-selective optical sensors (optodes) were introduced. The first improvement addresses the drawback of organic dye (optode-localized chromoionophore) photobleaching. This positively impacts fluorescence response and allows for (1) direct measurement of hydrogen ion activity upon binding with the dye,...

  • Employing capillary electrophoresis as a separation method for pharmaceutical analysis

    Creator:
    Lessard, Laura L.
    Abstract:
    Capillary electrophoresis as a technique has many applications in a broad range of fields including forensics, environmental analysis, and biological analysis and as a separation method for samples such as oligonucleotides, peptides, proteins, and pharmaceuticals. The research conducted herein is for the antibiotic pharmaceutical ciprofloxacin HCl and three impurities. Sample...

  • Development of materials and devices for separation of polyamido[a]mine dendrimers

    Creator:
    Tennico, Yolanda H.
    Abstract:
    Over the last decade, the use of highly branched macromolecules, called dendrimers, is emerging. Polyamidoamine (PAMAM) dendrimers, in particular, have attracted high interest due to their unique properties, such as well-defined size, shape, and solubility in water. Our group, as part of an interdisciplinary team, is currently working on developing...

  • An investigation into nitrogen uptake by Emilania huxleyi during continuous darkness

    Creator:
    Royer, Ida M.
    Abstract:
    Experiments were conducted with two strains of the coccolithophorid Emiliania huxleyi. Previous experiments with CCMP1742 and 372 at a light intensity of 60 µEin/m²-s showed that during five-day periods of continuous darkness, strain 1742 was taking up nitrate from the media while strain 372 was not. The nitrate uptake in...

  • Aroma compounds in sweet dry whey

    Creator:
    Mahajan, Shilpa S.
    Abstract:
    The objective of this study was to identify aroma volatiles in sweet whey powder. Volatiles were isolated by solvent extraction and solvent assisted flavor evaporation. Fractionation was followed to separate acidic volatiles from nonacidic volatiles. Gas chromatography/olfactometry and gas chromatography-mass spectrometry were used for the identification ofaroma compounds. Osme methodology...

  • Trace analysis of halogenated polycyclic aromatic hydrocarbons from an electronic waste recycling area and Guangzhou, China

    Creator:
    Gonzales, Leah R.
    Abstract:
    Halogenated Polycyclic Aromatic Hydrocarbons (X-PAHs) are ubiquitous contaminants that are thought to be generated by processes such as chemical industries and incomplete combustion, including waste incineration and electronic waste (e-waste) burning. X-PAHs are a concern for environmental and human health because they are toxic, mutagenic, and are expected to be...

  • Low-Dose X-Ray Radiation Effects On the Proteomic Profiles of Hippocampus, Cortex, and Cerebellum of Contextual Fear Conditioning and Novel Object Recognition Trained Mice

    Creator:
    Koluda, Rony
    Abstract:
    Radiation exposure to the brain can occur from a variety of events, including space missions, nuclear accidents, and clinical treatments. The effects of high dose radiation are well studied, but those of lower dosage are more elusive. Decline of memory and cognition is observed in patients exposed to low dose...

  • Polyion sensors based on induced ion extraction

    Creator:
    Fordyce, Katherine
    Abstract:
    A novel method for detecting the peptidase activity of clinically relevant peptidases was investigated using solid-contact electrochemical polyion sensors under chronopotentiometric control. Complete instrumental control over ion-extraction was accomplished by incorporating a lipophilic electrolyte into the ion-selective membrane; the sensors had no intrinsic ion-exchange capabilities. The sensors were used to...

  • Hydrolytic methods for the quantification of fructose-equivalents in herbaceous biomass

    Creator:
    Nguyen, Stefanie K.
    Abstract:
    A low, but significant, fraction of the carbohydrate portion of herbaceous biomass may be composed of fructose/fructosyl-containing components (“fructose equivalents”); such carbohydrates include sucrose, fructo-oligosaccharides, and fructans. Standard methods used for the quantification of structural-carbohydrate-derived neutral monosaccharide-equivalents in biomass are not particularly well suited for the quantification of fructose equivalents...
