Summary
Hydrophilic domains significantly enhance nanobubble stability on hydrophobic surfaces. This research reveals how surface properties influence nanoscale gas states, with bubbles persisting for days when hydrophilic domains are present.
Area of Science:
- Surface Science
- Nanotechnology
- Materials Science
Background:
- Nanobubbles, nanoscale gas states at solid/liquid interfaces, are crucial in various applications.
- Their stability and generation mechanisms on different surfaces require further investigation.
Purpose of the Study:
- To investigate the effect of hydrophilic domains on nanobubble generation and stability.
- To compare nanobubble behavior on hydrophobic surfaces with and without hydrophilic features.
Main Methods:
- Utilized peak force quantitative nanomechanics to study nanobubbles.
- Investigated nanobubble formation on Teflon amorphous fluoroplastic thin films.
Main Results:
- On purely hydrophobic surfaces, nanobubbles were few and rapidly diminished.
- Hydrophilic domains significantly promoted nanobubble generation and prolonged their stability.
- Nanobubbles persisted on surfaces with hydrophilic domains for up to three days.
Conclusions:
- Surface chemistry, specifically the presence of hydrophilic domains, is critical for nanobubble stability.
- Tailoring surface properties can control the longevity of nanobubbles for potential applications.

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

Micelle formation is an intricate process that hinges on the properties of amphiphilic or amphipathic molecules and the conditions of the system in which they are found. Amphiphilic molecules, which have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts, play a critical role in this process.In aqueous environments, these molecules arrange themselves such that their hydrophilic heads are turned towards the water phase, while their hydrophobic tails are oriented away...

Surfactants, named for their behavior at interfaces, positively adsorb at the interfaces of two phases, reducing interfacial tension. Their versatility as emulsifiers, detergents, and foaming agents stems from this ability. Surfactants, often termed amphiphiles, share the property of amphipathy, with molecules having both hydrophilic and hydrophobic portions. The hydrophilic part is called the head, and the hydrophobic part, including an elongated alkyl substituent, forms the tail.Surfactants...

The membrane domains concentrate specific lipids and proteins at one place within the membrane, which helps in cell signaling, adhesion, and other critical cellular processes. These domains can differ in size, composition, function, and lifespan.
Protein Domains
The membrane comprises a group of distinct proteins responsible for carrying out a cell's specific function. For example, the plasma membrane of the human sperm, or a single germ cell, contains a unique set of proteins in the...

Solution, Solubility, and Solubility Equilibrium
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules,...

4.4K
Different physical properties of lipids and proteins allow them to localize and form distinct islands or domains in the membrane. Some membrane domains are formed due to protein-protein interactions, whereas others are formed due to the presence of specific lipids such as sphingolipids and sterols—for example, large proteins, such as bacteriorhodopsin, aggregate and create distinct domains.
