"The UNOOSA DropTES 2019 program gave us the opportunity to study what, at the time, still was an unexplored physical phenomenon with promising space applications. Our international team, StELIUM, succeeded in developing a complex microgravity experiment and obtaining unprecedented data on the sloshing of ferrofluids in microgravity, gaining some invaluable real-life experience. As discussed in our publications, this has proven to be critical for the development of low-gravity magnetic positive positioning devices. Antonio, Francesco, Inés, Filippo, and I are extremely grateful to everyone who made this possible." - Álvaro Romero-Calvo, StELIUM team leader.

Politecnico di Milano was the winner of the 6th round of DropTES opportunities in 2019.
The team proposed to analyse the lateral sloshing of a ferrofluid solution in low-gravity with the aim of measuring its oscillation frequency while subjected to different magnetic field intensities. This result can be used to validate recently developed magnetic sloshing models, which would prepare the path for the design of magnetic sloshing dampers and other liquid management devices in reduced gravity environment.
