Characterization of Bulk Nanobubbles Formed by Using a Porous Alumina Film with Ordered Nanopores

Abstract: Gaseous nanobubbles (NBs), with their unique physicochemical properties and promising applications, have become an important research topic. Generation of monodispersed bulk NBs with specified gas content remains a challenge. We developed a simple method for generating bulk NBs, using porous alumina films with ordered straight nano-scaled holes. Different techniques, such as nanoparticle tracking analysis (NTA), atomic force microscopy (AFM), and infrared absorption spectroscopy (IRAS), are used to confirm NB … Show more

“…62,69 To this end, generation via nanoporous membrane might be an ideal approach to ll the nucleus of nanobubbles with oxygen. 133 However, in this method, the size of the nanobubbles is dictated by the diameter of the membrane nanopores. As such, this method is not appropriate for applications that need real-time control over the bubble size.…”

“…Ma et al use a nanoporous alumina membrane to generate bulk nanobubbles. 133 The alumina membrane is composed of nanoholes with a mean diameter of about 100 nm. The researchers employ the anodization technique as a simple, inexpensive, and efficient method to fabricate the membrane.…”
