Assessing Household Gac Water Filters For Pfas Removal From Private Drinking Water Wells, Mccallah Ferry

Williams Honors College, Honors Research Projects

This research paper delves into the efficacy of a typical household water filter in removing per- and polyfluoroalkyl substances (PFAS), a concerning class of chemicals prevalent in water sources. PFAS, known for their persistence and potential health risks, have prompted regulatory actions such as the Third Unregulated Contaminant Monitoring Rule (UCMR 3) and the National Primary Drinking Water Regulation (NPDWR) by the U.S. EPA. While municipal water utilities are subject to regulatory oversight, individuals relying on private wells face challenges in ensuring water quality.

Infant Molds For Cleft Deformities, Hannah Brunow, Drew Reinbolt, Rhonda Troyer, Christian Miller

Williams Honors College, Honors Research Projects

Cleft lip and palate are very common birth defects where the roof of a baby's mouth and lip do not form properly while in the womb. Babies born with cleft lip or palate can undergo surgery after going through a process to make the initial gap smaller through incrementally smaller, retainer-like appliances. We will be trying to find a way to improve the pre-surgery process by implementing 3D printing. We will be performing this research for a craniofacial orthodontist at Akron Children's Hospital. We hope that our success will lead to a decrease in the amount of time spent making …

Corrosion Inhibitors: Mitigating The Degradation Of Rebar, Jake R. Hughes

Williams Honors College, Honors Research Projects

Our conjecture was twofold: first, that two compounds historically used as food preservatives could act as environmentally friendly inhibitors against rebar corrosion, and second, that molecular properties have a quantifiable influence on inhibition efficiency (%IE). To evaluate the two compounds, cyclic potentiodynamic polarization was used to determine corrosion current density (i_corr) and %IE. The “green” inhibitor candidates included sodium metabisulfite and ascorbic acid, which yielded maximum %IE values of -123900% and 91%, respectively. Results indicated that sodium metabisulfite is not a suitable inhibitor, while ascorbic acid showed potential to extend reinforced concrete’s design life without posing health or …

Causational Analysis And Rectification Of Issues Concerning Scale Formation On Hot-Rolled Straight Bar Product And Its Effects On Ultrasonic Testing, Riley Mattix

Williams Honors College, Honors Research Projects

At Charter Steel's NDT Processing Plant located in Cleveland, Ohio, a concern has arisen regarding the recently implemented bar straightening and UT (Ultrasonic Testing) equipment. A substantial amount of mill scale, which is typically removed during the straightening process, is persisting on the bar’s surface throughout most of the NDT procedure. This lingering scale has been observed to flake off once inside the UT equipment, introducing unwanted noise and phantom peaks into the UT readings. Additionally, thick mill scale has been identified as a source of background interference in the received data. In contrast, bars that have been subjected to …

Removal Of Residual Stress In 3d Printed Polymers, Christian Jenkins

Williams Honors College, Honors Research Projects

This project aims to investigate the relationship between stress relaxation and the reduction of dimensional shrinkage and warping in 3D printed polymers produced through fused filament fabrication. The hypothesis suggests that residual stress in 3D printed structures results from factors such as temperature differences, molecular-level contributions, and rapid cooling, causing post-printing warpage and damage. To mitigate these issues, the project proposes annealing 3D printed polymers in a hot sandbath to allow stress relaxation without warping. The study will employ a Dynamic Mechanical Analysis (DMA) machine to assess mechanical properties of relaxed and unrelaxed samples, comparing their effectiveness. The project's timeline …
