This conference will serve as a global forum uniting researchers, innovators, and practitioners across the diverse and rapidly evolving fields of nanobubble, nanodroplet, and surface nanobubble science and engineering. Participants will explore both fundamental principles and cutting-edge applications, spanning environmental, agricultural, biomedical, and industrial domains. Suggested abstract topics include, but are not limited to:

 Nucleation, growth, stability, and interfacial dynamics
 Theoretical modeling, molecular simulation, and scaling laws
 Advanced characterization, imaging, and measurement techniques
 Gas–liquid–solid interactions and surface wettability phenomena
 Physicochemical properties and phase behavior at the nanoscale

• Environmental Applications
 Water and wastewater treatment using bulk, surface, or encapsulated nanobubbles
 Pollutant degradation and separation (e.g., PFAS, antibiotics, pesticides, HABs, cyanotoxins, and microplastics)
 Resource recovery, circular economy approaches, and zero-liquid discharge systems
 Soil remediation, oxidation, and restoration using gas nanodroplets or surface nanobubbles

• Agricultural and Food Systems
 Enhancement of irrigation efficiency, oxygenation, and crop productivity
