New Inorganic Pigments from Mineral Structures

O Criador:: Schettini Mejia, Carlo A.
Abstract:: The discovery of new blue pigments is a field of great interest, as commercially available pigments present properties that make them undesirable such as poor sustainability, cost, and stability. By researching solid solutions with the melilite structure, we discovered a new solid solution Sr2Zn1-xNixGe2O7, with 0.1 ≤ x ≤ 0.6,...

Ionic Strength and pH: A Look at Nanostar Stability

O Criador:: Aldous, Tanner J. E.
Abstract:: Nanostars have many potential applications, particularly in biomedicine, such as drug delivery, detection assays, and even cancer treatment. Seeing how their plasmon changes in response to changes to the environment of the nanostars can give us an insight to the stability of the nanostars. Our current studies involve the effect...

Derivation of Halide Bond Lengths through Fourier Transform Infrared Spectroscopy

O Criador:: Gonzales, Seth
Abstract:: The physical properties of hydrochloric acid and deuterium chloride were derived through the use of the harmonic oscillator and rigid rotor quantum mechanical models. By first obtaining angular momentum quantum values for HCl and DCl through Fourier Transform Infrared Spectroscopy, these two systems could be summed and processed with additional...

Molecular Structures of Gases by Electron-Diffraction: Improved Methods and Study of 1,1,3,3-tetramethylcyclobutane and spiropentane molecules

O Criador:: Sandwisch, Jason W., Nibler, Joseph, and Hedberg, Kenneth
Abstract:: The gas phase electron-diffraction (GED) technique has been the primary method used to expand our knowledge and understanding of gas-phase molecular structures. The technique yields interatomic distances and bond angles that are of use in both theoretical and experimental studies. The GED structural parameters are thermal averages over all vibrational...

Development of a Antibacterial Disc Diffusion Assay to Differentiate Fusarin C from Non-Fusarin C activity in Early Screening of Mutant Fusarium graminearum Extracts

O Criador:: Svendsen, Molly, Luelling, Sarah, Adpressa, D., Godbey, Aly, Belizi, Peter, Carlson, Caleb, Loesgen, S., Freitag, M., Smith, Kristina, and Gautschi, Jeff
Abstract:: The discovery of novel compounds with antibacterial properties continues to be critically important.3 One potential source of such compounds is the cryptic genome of fungi known to produce biologically active molecules. A kmt6 mutant of the cereal pathogen Fusarium graminearum was previously developed through a histone H3 lysine 27 methyltransferase...

Mass Spectrometry-based Detection of Neonicotinoids on Honey Bees

O Criador:: Trevor, Shear, Morré, Jeff, and Hooven, Louisa
Abstract:: With increasing use of new pesticide formulations worldwide to repel and kill unwanted organisms, negative consequences on non-target species such as honey bees and other pollinators are of increasing concern and not well studied. This study compares the nanotechnology based pesticide (NBP) Safari and its base neonicotinoid, dinotefuran, and their...

Colorimetric analysis of creatinine in whole blood and urine in a novel paper/polycaprolactone microfluidic device

O Criador:: Pommerenck, Joel, Heist, Christopher A., and Remcho, Vincent T.
Abstract:: A novel approach for the colorimetric detection of creatinine in a paper/polycaprolactone hybrid microfluidic device using alkaline3,5-dinitrobenzoate (DNB) is described. The reaction parameters of reagent concentration, alkalinity, and analysis time are optimized for fast reaction times and high color yield. Microfluidic devices incorporating this assay are designed and fabricated to...

Identification of Novel Biomarkers in urine from Canine Transitional Cell Carcinoma Patients

O Criador:: Pope, George, Yang, Liping, Goodall, Cheri, Schlueter, Andrew, and Bracha, Shay
Abstract:: • Bladder Cancer in the United States has progressively been one of the more common cancers and is estimated to have 74,000 new cases as well as 16,000 deaths in 2015.1 • This type of cancer also has one of the highest rates of recurrence with an average of 60%...

Chemical Screening and Antibacterial Testing of Fungal Endophytes

O Criador:: Pham, Andrew
Abstract:: Endophytes are bacteria or fungi that live within a host plant. The plant host provides a home for endophytes, and in return endophytes produce primary and secondary metabolites, of which many of the secondary metabolites possess biological activities. When microorganisms are grown under various media conditions, they produce different natural...
