Nanobubbles and nanodrops [PDF]
, 2013 In this thesis we address the behaviour of so-called surface nanobubbles. These nanobubbles behave different from ordinary (macroscopic) bubbles in several ways: (i) The gas-side contact angles of surface nanobubbles are lower than those of regular bubbles (i.e.

The European Physical Journal Special Topics, 2013 The experimental evidence for the existence of nanobubbles is summarized. The paradox represented by their stability and the apparent contradiction with the Laplace-Young equation is discussed in detail. A review of surface thermodynamics is given, which shows that nanobubbles are only stable in water super-saturated with air, and also that the surface

Comment on “Bulk Nanobubbles or Not Nanobubbles: That is the Question” [PDF]
Langmuir, 2020 In a recent article, Jadhav and Barigou ( Langmuir 2020, 36 (7), 1699-1708) investigated the question of the existence of stable bulk nanobubbles in water generated by hydrodynamic cavitation, ultrasound cavitation, and the addition of an organic compound (namely, ethanol) to water.

Nanobubbles in Hydroponics [PDF]
The Third International Tropical Agriculture Conference (TROPAG 2019), 2020 Maintaining oxygen levels in the nutrient solution of hydroponic systems, particularly thoseusing the deep flow technique (DFT), is essential for root uptake of nutrients and for cellularrespiration. [...]

Response to “Comment on Bulk Nanobubbles or Not Nanobubbles: That is the Question” [PDF]
Langmuir, 2020 Advanced techniques that combine high spatial resolution with chemical sensitivity to directly probe the observed nanoentities and provide direct evidence that they are truly gas-filled nanobubbles do not exist. Therefore, in our paper, we focused on providing, for the first time, multiple types of indirect evidence using a variety of physical and ...

From Bubbles to Nanobubbles [PDF]
Nanomaterials, 2021 Nanobubbles are classified into surface and bulk. The main difference between them is that the former is immobile, whereas the latter is mobile. The existence of sNBs has already been proven by atomic force microscopy, but the existence of bNBs is still open to discussion; there are strong indications, however, of its existence. The longevity of NBs is

Plasmonic Nanobubbles–A Perspective [PDF]
The Journal of Physical Chemistry C, 2021 The field of plasmonic nanobubbles, referring to bubbles generated around nanoparticles due to plasmonic heating, is growing rapidly in recent years. Theoretical, simulation and experimental studies have been reported to reveal the fundamental physics related to this nanoscale multi-physics phenomenon. Using plasmonic nanobubbles for applications is in

Foods, 2021 Removing foodborne pathogens from food surfaces and inactivating them in wash water are critical steps for reducing the number of foodborne illnesses. In this study we evaluated the impact of surfactants on enhancing nanobubbles’ efficacy on Escherichia ...

Surface nanobubbles and nanodroplets [PDF]
, 2015 Surface nanobubbles are nanoscopic gaseous domains on immersed substrates which can survive for days. They were first speculated to exist about 20 years ago, based on stepwise features in force curves between two hydrophobic surfaces, eventually leading ...
