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 28 February 2027.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 June 2027.

Abstract

NON-TECHNICAL SUMMARY This grant supports research efforts to create a knowledge base for the rational and deterministic synthesis of high-entropy alloy (HEA, a complex solid comprised of five or more metals) nanocrystals with controlled surfaces in terms of both atomic composition and arrangement. Because of the diversity in composition, the surface of a HEA nanocrystal naturally presents an enormous number of…
