Colloids

21.5K
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...

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 visible to the naked eye or seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. The suspended particles in a suspension settle out after some time of mixing. The separation of particles from a suspension is...

Van der Waals Interactions01:24

Van der Waals Interactions

72.3K
Atoms and molecules interact with each other through intermolecular forces. These electrostatic forces arise from attractive or repulsive interactions between particles with permanent, partial, or temporary charges. The intermolecular forces between neutral atoms and molecules are ion–dipole, dipole–dipole, and dispersion forces, collectively known as van der Waals forces.

First Law: Particles in Two-dimensional Equilibrium

16.9K
Recall that a particle in equilibrium is one for which the external forces are balanced. Static equilibrium involves objects at rest, and dynamic equilibrium involves objects in motion without acceleration; but it is important to remember that these conditions are relative. For instance, an object may be at rest when viewed from one frame of reference, but that same object would appear to be in motion when viewed by someone moving at a constant velocity.

Colloidal precipitates01:09

Colloidal precipitates

6.6K
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...

Theories of Dissolution: The Danckwerts' Model and Interfacial Barrier Model

827
Various dissolution theories provide insight into the factors that influence the dissolution rate. Danckwerts' Model suggests that turbulence, rather than a stagnant layer, characterizes the dissolution medium at the solid-liquid interface. In this model, the agitated solvent contains macroscopic packets that move to the interface via eddy currents, facilitating the absorption and delivery of the drug to the bulk solution. The regular replenishment of solvent packets maintains the...

Area of Science:

  • Colloid and Surface Science
  • Materials Science
  • Computational Chemistry

Background:

  • Pigment dispersions, crucial for inks, plastics, and coatings, exhibit complex emergent structures.
  • These structures arise from nanoparticle aggregation influenced by particle size, concentration, and interactions.

Purpose of the Study:

  • To investigate how primary particle size affects structural emergence in organic pigment dispersions.
  • To establish a predictive model for pigment properties based on emergent structure.

Main Methods:

  • Milling organic pigment yellow 14 (PY14) to four primary particle sizes.
  • Quantifying inter-aggregate interactions using the second virial coefficient (A2).
  • Utilizing dissipative particle dynamics simulations with derived interaction potentials.

Main Results:

  • Smaller primary particle sizes led to increased aggregation.
  • The second virial coefficient (A2) increased with particle size, indicating stronger long-range repulsion.
  • Emergent structure was linked to percolation concentration and filler mesh size.

Conclusions:

  • Predictive modeling of pigment properties is achievable by understanding emergent structure.
  • Particle size is a critical factor controlling aggregation and emergent properties in pigment dispersions.
  • Dissipative particle dynamics simulations offer a scientific approach to analyze these complex systems.
