Beeswax Wraps As An Alternative To Single-Use Plastics, Sarah Skiver
Beeswax Wraps As An Alternative To Single-Use Plastics, Sarah Skiver
Williams Honors College, Honors Research Projects
The project goal was to compare the food storage efficacy of sustainable beeswax wraps verses the single-use plastic methods of resealable plastic sandwich bags and plastic cling wrap. The goal was also to test the reusability of the beeswax wraps, as it is a key advantage of beeswax wraps that is advertised. The project purpose was to explore sustainable and eco-friendly alternatives to single use plastics, which are harmful to the environment in both their production and their disposal. Food spoilage was compared in beeswax wrap, plastic sandwich bags, and plastic cling wrap, and spoilage was also observed in a …

Cold Plasma Enhanced Active Sites On Supported Nip Nanoparticles For The Oxygen Evolution Reaction, Michael Ricci
Williams Honors College, Honors Research Projects
Identifying materials to efficiently facilitate the oxygen evolution reaction (OER) is key to advancing water electrolysis, an essential technology in the pathway towards a sustainable energy future. Here, we explore cold-plasma treatment as a facile method to enhance the activity of NiP nanoparticles supported on activated carbon. NiP nanoparticles were synthesized on an activated carbon support using a solid-state method and were then treated with argon, oxygen, and hydrogen plasmas for extended times. In all cases, plasma treatment reduced the number of active sites on the support. OER activity was evaluated by testing the materials in alkaline conditions. The activities …

Zips Precious Plastics: Plastic Extruder, Patrick Cole
Williams Honors College, Honors Research Projects
This project's goal was to design and build an affordable desktop filament extruder that can precisely and consistently extrude filament to a certain tolerance acceptable for 3D printers using wasted printing material. The group is partnering with an on campus organization focusing on engineering applications for sustainable futures. Zips Precious Plastics is a student run design group that intends to bring an innovation space on campus to help educate students about the importance of a closed looped system within plastic manufacturing.
