I visited Fede Toschi group @ TU/e Eindhoven (NL). Here some nice old and new experiments I have seen.

Great pleasure and pride to have taken part in this event to celebrate Luca together with his many talented colleagues and collaborators.

It has been a great pleasure to collaborate on this study, which investigated ice formation in a convective cell containing salt water. The experiment is fascinating because it involves at least three characteristic scales associated to the turnover of the fluid, the phase change, and the diffusion of salt—and it is only by monitoring everything over about twenty days that one can truly appreciate this. After many ups and downs with various journals, the work has been published in PRL [https://doi.org/10.1103/mct1-6hbw] and highlighted by the editor. Below is also an article where I discovered my Chinese name. https://www.tsinghua.edu.cn/info/1175/121105.htm

How can particles or bubbles injected into a fluid control the onset of large-scale thermal convection in a Rayleigh-Bénard system?
