In this episode, we explore the complexities surrounding nanobubbles, focusing on their generation,

characterisation, and stability. We explain how electric field methods of generating nanobubbles yield a notably higher zeta

potential and higher nanobubble populations per unit volume, leading to longer-lived bubbles compared to those produced through mechanical methods. We look at how rigorous experimentation, including laser light scattering, has provided a deeper understanding of nanobubble population dynamics over time. We touch upon the critical factors of temperature and pressure sensitivity of nanobubbles, highlighting their implications for industrial applications.

This conversation sets the stage for our next episode, where we will dive deeper into the environmental and industrial applications of nanobubbles, building on the foundational scientific

concepts discussed today.

Thank you for joining us, and we look forward to continuing this fascinating exploration of nanobubble technology in our upcoming discussions.
