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 August 2028.
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

This grant will support research that looks to contribute to new knowledge related to the nonlinear dynamics of acoustic cavitation enhanced by vortex ultrasound. Acoustic cavitation is the process of bubble formation, oscillation, and collapse in a liquid exposed to intense ultrasound. Acoustic cavitation has been widely used in the biomedical field for tissue ablation, thrombolysis, drug delivery, etc., and in…
