The objective of this present study is to examine the effect of nanobubbles on the physical properties improvement in the chosen water sample. So far, the research outcomes stated that the physical properties could be enhanced by addition of nanoparticles, but very few studies were performed with nanobubbles. The unique properties of nanobubbles (70–120 nanometers) explain their use in a wide range of engineering fields. Simple method for producing nanobubbles in a variety of aqueous solutions along with examples of their use is outlined in this work. Global environmental issues, including the deterioration and depletion of water supply are driving today's need for water treatment technology. As a solution, the use of micro‐ and nano‐bubble (MNB) technologies in wastewater treatment has evolved. This page discuss the fundamentals of water treatment research, including their stability of bubbles, manufacturing processes, and chemical and physical features.

“…The thermal conductivity will be significantly increased as a result of this clustering (Alias & Ani, 2017; Bindhu et al., 2015; Fernandes et al., 2020; Nasibulin et al., 2001; Piloto‐Rodríguez et al., 2014; Żyła, 2017). Due to their high thermal conductivity compared to metallic oxides, copper oxides have also been examined (Rameshkumar, LakshmiSankar et al., 2019; Rameshkumar et al., 2021; Rameshkumar, Senthilkumar et al., 2019; Senthilkumar et al., 2020, 2018). In order to create cupric oxide nanofluids, copper (II) acetylacetonate, the precursor, underwent thermal decomposition at a temperature of 705°C, yielding a combination of copper oxide and copper nanoparticles.…”

The objective of this review paper is to implement and investigate of micro‐nano bubble technology for enhancement of condensation heat transfer. Micro‐nano bubbles dispersions in aqueous solutions can stay for a substantial time. As an example, 20 micron size micro‐nano bubbles take daily to rise one meter. Because the inertia force of fluid current exceeds the buoyant force, any currents within a large vessel would be anticipated to entrain kind of micro‐nano bubble dispersion. Micro‐nano bubbles will vaporize hotter water toward the center of the plume and convert that extra heat of transition to the cold wall, where it will condense the vapors and release latent heat if the condenser is arranged in the micro‐nano bubble‐assisted airlift configuration.

“…Tremendous application of Nanobubbles contributed their existence in many sectors like degradation of organic chemicals (Liu et al 2010 ) and environmental biotechnology like cleaning solid surface and wastewater treatment (Liu et al 2012 , C.Rameshkumar et al 2019a ). Nanobubbles have a slow dissolution rate for hours or up to days due to enormous internal pressure compared with microsecond lifetime for macroscopic bubbles (C.Rameshkumar et al 2019b ). In addition, the surface Nanobubbles under enormous tensile stress are highly stable (Uchida et al 2011 ; Chen et al 2011 ).The biomedical application shaving in biological systems had tried out different types of nanoparticles’ inclusion to achieve the biocompatibility (Kim et al 2011 ).…”

The current research is focused to address the implementation of nanobubbles technology to antibacterial agents against Staphylococcus aureus infections. Nanobubbles technology is a novel, latest research employed in many medical fields including drug discovery. In this present work, supramolecular nanoliquid formulation of potential antiseptic agent chloroxylenol-based Dettol and its enhanced antibacterial activity, biocompatibility assessment was studied. Nanobubble technology was adopted to prepare nanoformulation (NB-D) using a household hand mixer under thermostatically controlled conditions. A high-stability nanoformulation with high potential antibacterial activity against human pathogenic strains of Pseudomonas aeruginosa and Staphylococcus aureus was produced by the nanobubbles created in the antiseptic solution. The overall vitality of both strains was significantly reduced in all dose tests on NB-D treatment as a result of the antibacterial activity as assessed by the well-diffusion assay, turbidometric microdilution assay, biofilm inhibition assay, and total count reduction assay. Biocompatibility of the NB-D formulation was studied by the determination of cytotoxicity against HaCaT—human keratinocytes and hemocytes. NB-D treatment did not induce any notable cytotoxic effect on HaCaT cells by showing none of the changes in cell morphology and architecture. No toxic effect on the hematocytes was observed in NB-D treatment. The enhanced antibacterial activity and best biocompatibility of NB-D result shows that the nanobubble technology could be used as an effective strategy for the formulation of antiseptics or disinfectants against high health risk infectious organisms. The novelty of the work is the formation of supramolecular nanoformulation on antiseptic agent which promised the results enhanced than the raw antiseptic agent.
