Research
Nanobubbles (NB), previously defined as gas-filled bubbles smaller than 1.0 μm, are now characterized as having diameters within 100–200 nm. Produced via hydrodynamic cavitation, these bubbles exhibit distinct properties like high oxygen solubility, prolonged stability in water, and the generation of reactive oxygen species (ROS).
While various applications — including enhancing plant growth, seed germination, microbial proliferation, and micropollutant removal — have been noted, our research rigorously investigates nanobubbles' benefits in wastewater treatment, agriculture, and aquaponics. Our lab was among the first to demonstrate that ozone nanobubbles achieve significantly greater disinfection efficiency than conventional microbubbles at equivalent doses.
