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 January 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 31 May 2029.

Abstract

Liquids composed of polymers exhibit unusual flow properties. These liquids contain long, flexible molecular chains that induce surprising behaviors in flow. Even when flowing slowly, they can generate a chaotic motion called elastic turbulence. When flowing rapidly, they can generate another chaotic state called elasto-inertial turbulence. These unusual flow behaviors are seen in common materials such as saliva,…
