Design Of Pigments For Use In “Cool” Coatings, Tyler Laughorn
Design Of Pigments For Use In “Cool” Coatings, Tyler Laughorn
Williams Honors College, Honors Research Projects
This project was focused on the development and testing of several novel pigments that exhibit high NIR-reflectance and therefore show potential for use in “cool” coatings. A “cool” coating will reflect more solar radiation than other standard coatings, and so a coated structure would require less energy to keep cool. Four sets of pigments were synthesized: Co1-xMgxCr2O4 (teal), Co0.25Mg0.75Cr2-yAlyO4 (blue), Ti1-x-yNixSbyO2 (yellow), and Cr2-xFexO3 (black). NIR and TSR values were then measured …

Filtration Apparatus Design For Oil-Water Separation Using Membranes And Sponges, Alec Jerger
Williams Honors College, Honors Research Projects
It can be difficult to separate water and oil emulsions through traditional filtration. Therefore, investigations of filtering using thermo-responsive (TR) polymers, in this case poly(vinyl methyl ether) (PVME), was conducted. It’s hypothesized that below its lower critical solution temperature (LCST), PVME has an affinity for water while oil substances do not. Above the LCST the opposite will be true. To verify this hypothesis, iterations of filtration designs were created to provide optimum control over the parameters to measure flow. The final optimized experimental apparatus was a Chromaflex glass column which was air tight and controlled all parameters besides fluid flow. …

Synthesis Of Bio-Based Polymer Products, Joshua Sukie
Williams Honors College, Honors Research Projects
The project covers the synthesis of two bio-based polymers. One aspect of the research investigates the synthesis of materials for use in vegetable oil-based UV-curable coating, and the subsequent polymerization of the materials into a coating film. The second aspect of the research follows the synthesis of a functionalized cellulose material for use as a reinforcer in a vegetable oil-based composite. Both products are subsequently analyzed by various methods.
