Nanobubbles for energy and environment: A short review

Abstract

The application of nanobubble technology in many sectors, covering water treatment, blood flow visualization, and drug delivery had drawn great attention nowadays. Being eco-benign and comfort of generation and use, the nanobubble technology is superior to conventional processes that use biological or chemical elements. However, there is still much to learn about the processes of nanobubble applications. One of the key difficulties for a deeper knowledge of the technology is the characterization and use of nanobubbles (NBs) for energy harvesting applications. In addition to current particle characterization methods, particularly that can be used to describe nanobubbles; this article also briefly discusses few of their potential uses. The novelty of the review article is to create consciousness among heat transfer scientists that nanobubbles technology is a new era in the energy sector.
