Abstracts

Michael L. Standish, Radical Polymers, LLC, "Ground Up: Designing New Polymers for Independent Water Treatment Companies"

This presentation introduces two new polymers to the AWT membership and takes the membership through the process of design, development, and competitive evaluation of the polymers for mineral scale and deposit control. INITIA™ 585 is an Enhanced Poly-­‐Maleic Acid (EPMA) polymer that exhibits exceptional crystal modification properties for calcium carbonate. INITIA™ 205 is a High Performance Sulfonated Polymer (HPSP) designed for calcium phosphate and iron stabilization. The insight into the development of these two new products provides a unique perspective into the primary considerations of monomer selection and ratio tradeoffs, molecular weight optimization, and the balance of performance versus multiple mineral scale types. The presentation includes an overview of polymer functionality where structure-­‐function properties of common water treatment polymers are detailed. The concepts of Threshold Inhibition, Crystal Habit Modification, and Particulate Dispersion are defined and applied to laboratory evaluation data for the new polymers for common mineral scales and deposits such as Calcium Carbonate, Calcium Phosphate and Iron. These data are then applied to suggested uses and formulations for cooling water and boiler applications.

 

Ben Rybolt, UT Knoxville, Dept of Physics,  PhD candidate, "Detecting Neutrinos with the Double Chooz Experiment"

Neutrinos are the most abundant particle in the universe but because they only interact through the weak force they are elusive to measure. The Double Chooz Experiment detects Neutrinos created in a nearby nuclear reactor and measures the disappearance rate of the electron flavored anti-neutrinos. An overview will be given of the field of neutrino physics, basic detection principles will be described and the chemical properties of liquid scintillator which make detection possible will be highlighted.

 

Bethel Seballos, University of the South at Sewanee, "The impact of calcium on the progression of fibrotic lung disease"

Pulmonary fibrosis is an incurable disease belonging to a class of disorders known as Interstitial Lung Diseases, all of which lead to progressive scarring of the lungs. Fibrosis results when specialized cells called myofibroblasts are recruited to repair damage, but do not die or migrate away once the repair is complete. Our current hypothesis is that the presence of calcium impacts the fate of these cells. Through scratch assay experiments, we have observed calcium-dependent changes in cell migration and proliferation. Immunocytochemistry has revealed calcium-dependence of cytoplasmic expression of alpha-smooth muscle actin, a hallmark of myofibroblasts. . Further studies on cells isolated from both “healthy” and “diseased” subjects may allow for determination of the pathways which are impacted by changes in calcium homeostasis in lung myofibroblasts.
