Understanding the Stabilization of a Bulk Nanobubble: A Molecular Dynamics Analysis
Langmuir, 2021Bulk nanobubbles (NBs) have received considerable attention because of their extensive potential applications, such as in ultrasound imaging and water management. Although multiple types of experimental evidence have supported the existence and stabilization of bulk NBs, the underlying mechanism remains unclear.

Rheology of highly concentrated bulk nanobubbles in water
NanoscaleBulk nanobubbles (BNBs), unlike macro bubbles, exhibit extraordinary longevity in water, and can be produced at higher concentrations than previously thought.

Role of Capillary Fluctuations in Stabilizing Bulk Nanobubbles
LangmuirThe existence of bulk nanobubbles (BNBs) has long been questioned, primarily due to the limitations of experimental techniques and the widespread assumption that spherical bubbles cannot achieve a stable equilibrium. In this study, we develop a model that describes the stability of BNBs based on experimental observations, revealing that the intensity N

Interfacial Thermal Fluctuations Stabilize Bulk Nanobubbles
Physical Review LettersConsensus on bulk nanobubble stability remains elusive, despite accepted indirect evidence for longevity. We develop a nanobubble evolution model by incorporating thermal capillary wave theory that reveals that dense nanobubbles generated by acoustic cavitation tend to shrink and intensify interfacial thermal fluctuations; this significantly reduces ...

Stabilization of bulk nanobubbles with a hydrate layer
Коллоидный журнал / Colloid JournalThe stabilization of nanobubbles is considered with the balance of the Laplace pressure at their boundary due to surface tension and electrostatic pressure due to Coulomb forces. The presence of a hydrate layer of thickness ~1 nm with a tangential orientation of water dipoles around it is taken into account, the low permittivity of which, approximately

ANALYSIS OF THE STRUCTURE OF BULK NANOBUBBLES IN WATER
Nanoscience and Technology: An International JournalIn this study, we determined the components of the total electrostatic pressure (PC) at the nanobubble boundary and found that a negative pressure arises between the spheres of the polarization charge and the bubble shell. The results revealed that the counterion pressure (Pd) of the diffuse layer is P<sub>d</sub> << P< ...
