  1. 3377. (I) Monitoring Humulone Isomerization Using Raman Spectroscopy: A Bitter Problem in the Microbrewing Industry
    William M. Whelan (University of Prince Edward Island)

    Invited Speaker / Conférencier(ère) invité(e)

    Raman Spectroscopy is being explored to improve the characterization of beer bitterness which is derived primarily from the addition of the annual flowers (cones) of the perennial climbing vine Humulus lupulus (common hops). The hops cones contain humulones which are thermally isomerized into isohumulones during the brewing process. The isohumulones are highly bitter and contribute to the...

  2. 3078. (G*) Rapid Detection of Bacterial Pathogens in Water and Clinical Specimens Using Laser-Induced Breakdown Spectroscopy
    Emma Blanchette (University of Windsor)

    Physics in Medicine and Biology / Physique en médecine et en biologie (DPMB-DPMB)
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    Our lab is developing laser-induced breakdown spectroscopy (LIBS) as a method to rapidly diagnose bacterial infections. Rapid diagnosis of bacterial infections would improve clinical response times, reduce the overuse of broad-spectrum antibiotic drugs, and improve patient outcomes. LIBS is a spectrochemical technique that can rapidly identify the elemental composition of a specimen. The...

  3. 3351. (G*) A novel optical filter-based Raman system operating in strong ambient light for in vivo clinical applications
    Mr Hao Guo (Dalhousie University)

    Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    A portable optical system and methods have been developed for real-time synchronous detection of vibration and rotation modes in biotic systems. It consists of a modulated light source, laser beam shaping and light collecting optics, optical detectors, appropriately selected optical filters, a laser beam modulator, current-to-voltage converters, and lock-in amplifiers. The weak signal of...

  4. 3316. (G*) Using synchrotron radiation techniques as a tool in invertebrate paleontology
    Mr Jerit Mitchell (Physics Department, University of Regina.)
    08/06/2022, 11:45
    Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    Over the past decade there has been a revolution in the methods that paleontologists use to analyze the remains of organisms that lived millions of years ago. Using the exceptional brightness of synchrotron light it is now possible to analyze bones and fossil insects in better detail than ever before, as well as provide new technical methods for research. While fossil vertebrates like...
