Happy National Intern Day!
This week, we’ve been highlighting some of our Summer Undergraduate Research Fellowship (SURF) student interns in honor of this special day.
Meet Remi Mellinghoff, an Environmental Engineering major at Yale University. Remi is researching the rate of chemical changes during outdoor sunlight weathering of polyamide pellets in Hawaii.
Q: What is your NIST campus location?
I work at the Center for Marine Debris Research in Waimanalo on Oahu, Hawaii. The center is a partnership between NIST and Hawaii Pacific University, and we are part of NIST’s Biochemical Exposure Sciences Group.
Q: What is a high-level overview of the work you do at NIST?
My work seeks to determine how weathering changes the chemical composition of polymers. More specifically, my project focuses on polyamide nylon, the material that commercial fishing nets are made of. Out in the ocean, when fragments or large segments of the net get disconnected from fishing boats, they continue to trap marine animals – a phenomenon known as ghost fishing. I am creating a calibration curve of photooxidation time versus carbonyl index and melting temperatures of four main nylon varieties. If we can quantify the effect of weathering on nylon's chemical properties, we can better predict the degradation of these fishing nets and inform solutions to a major problem in our oceans.
Q: What has been your greatest accomplishment at NIST so far?
Getting the word out! Our Center does a lot of outreach events on Oahu. The narrative regarding plastics is overwhelming and disheartening; it seems like an insurmountable problem. At a recent event at the Waikiki Aquarium, I realized we have the ability to foster a more positive and optimistic attitude, just by talking about our work!
