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

NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2028.

Abstract

Many naturally occurring microorganisms can produce soap-like substances, called biosurfactants, that alter how fluids and other substances in the liquids move through porous spaces such as soils and biological tissues. However, scientists still do not know how far and how fast these biosurfactants spread or how they redirect substances ranging from nutrients and pollutants to disease-causing bacteria. Yet, these…
