Jelle attended the Nanobubble 2022 conference, hosted by the Otto-Von-Guericke University in Magdeburg (Germany). The conference was well-attended by experts working in the field of nano- and microbubbles, with a balance between people working on the theory and applications. The conference had 7 invited talks by well-established speakers, and 50 contributed talks by speakers from more than 20 different countries. Jelle gave a talk with the title “Towards better understanding of the energy transfer in thermocavitation”. This talk led to an interesting discussion on the use of microbubbles for needle-free jet injection and potential new collaborations with other attendees.
