Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 July 2031.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 November 2031.

Abstract

NONTECHNICAL Summary This award supports computational research and education to advance understanding of physical polymer aging, the process where the configuration of atoms relaxes over time leading to changes the properties of polymers. Polymers are long chain molecules made of several repeating units. When these chains are tangled and randomly arranged without any order, the polymer is said to be ‘amorphous’.…
