Summary
Liquid active surface growth (LASG) explains abnormal nanoparticle formation. The interplay between droplet expansion and shell encapsulation creates unique nanostructures like hollow nanobottles.
Area of Science:
- Nanotechnology
- Materials Science
- Chemical Engineering
Background:
- Previous studies highlighted dynamic interplay, not static control, in metal nanoparticle growth.
- This principle of active site formation was previously unapplied to liquid nanoparticle systems.
Purpose of the Study:
- To explain the abnormal growth modes observed in liquid nanoparticles.
- To introduce and validate the concept of liquid active surface growth (LASG).
Main Methods:
- Investigated the interplay between droplet expansion and silica shell encapsulation.
- Conducted carefully designed control experiments to demonstrate synthetic control.
Main Results:
- Identified LASG as the mechanism driving unique nanostructure formation.
- Demonstrated that imbalance in droplet expansion and encapsulation is critical for synthetic control.
- Showcased the ability of LASG to produce diverse liquid-derived nanostructures.
Conclusions:
- LASG provides a unified mechanism for various liquid-derived nanostructures (hollow spheres, teardrops, nanobottles).
- Adapting nanosynthesis techniques to the liquid realm via LASG offers enhanced control and insights.
- This approach has the potential to advance the synthesis of complex nanostructures.

When a paint brush is immersed in water, the bristles wave freely inside the water. When it is taken out, the bristles stick together. The reason behind this effect is surface tension.
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...

Surface Tension
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

01:22Surface Tension of Fluid

Surface tension is a fundamental property of fluids, occurring at the boundary between a liquid and a gas or between two immiscible liquids. This phenomenon arises from the cohesive forces between molecules at the fluid's surface, creating an effect similar to a stretched elastic membrane. Inside each fluid, molecules are equally attracted in all directions by neighboring molecules, but surface molecules experience a net inward force, resulting in surface tension.

01:13Excess Pressure Inside a Drop and a Bubble
1.6K
The shape of a small drop of liquid can be considered spherical, neglecting the effect of gravity. This drop can further be considered as two equal hemispherical drops put together due to surface tension. The forces acting on the spherical drop are due to the pressure of the liquid inside the drop, the pressure due to air outside the drop, and the force due to the surface tension acting on the two hemispherical drops.

500
The high insolubility of some precipitates can result in an unfavorable relative supersaturation. This can lead to colloidal particles with a large surface-to-mass ratio, where adsorption is promoted. For instance, in the precipitation of silver chloride, silver ions are adsorbed on the surface of the colloidal particles, forming a primary layer. This layer attracts ions of opposite charge (such as nitrate ions), forming a diffuse secondary layer of adsorbed ions. This electric double layer...

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,...
