We are pleased to share that our recent study, “Comparative Study of CO₂ Nanobubbles and Macrobubbles: Effects on Water Chemistry, Microalgal Growth, and Carbon Utilization”, has been published in Water Research.
This work demonstrates that CO₂ nanobubbles significantly enhance gas–liquid mass transfer efficiency, carbon utilization, and algal biomass productivity compared to conventional macrobubbles. In cultivation experiments with Scenedesmus obliquus, nanobubbles boosted biomass yields and improved carbon utilization efficiency, highlighting their potential role in carbon capture and utilization (CCU) strategies.
Our findings provide new insights into sustainable CO₂ management through algal biotechnology and underscore the broader role of nanobubble technology in global CO₂ reduction.
