Colloids

19.3K
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...

Colloidal precipitates

2.4K
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...

First Law: Particles in Two-dimensional Equilibrium

11.2K
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.
Newton's first law tells us about...

Coagulation01:06

Coagulation

592
Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...

First Law: Particles in One-dimensional Equilibrium

7.5K
Newton's first law of motion states that a body at rest remains at rest, or if in motion, remains in motion at constant velocity, unless acted on by a net external force. It also states that there must be a cause for any change in velocity (a change in either magnitude or direction) to occur. This cause is a net external force. For example, consider what happens to an object sliding along a rough horizontal surface. The object quickly grinds to a halt, due to the net force of friction. If...

Area of Science:

  • Colloid and Surface Science
  • Materials Science
  • Computational Chemistry

Background:

  • Inverse patchy colloids (IPCs) are specialized particles with specific attractive regions.
  • Understanding their self-assembly is key to designing novel materials.

Purpose of the Study:

  • To investigate the 2D equilibrium self-assembly of IPCs.

  • Systematic variation of patch coverage (0.5, 0.33, 0.22, 0.12) and particle density.
  • Characterization of ordered phases using bond order parameters (ψ4, ψ6) and radial distribution functions.

Main Results:

  • Stable square and triangular crystals observed at 0.5 patch coverage.
  • Rhombic and triangular crystals emerged as stable phases at 0.33 patch coverage.
  • Triangular crystals stabilized at low patch coverages (0.22, 0.12) and high densities.
  • Kinetically stable clusters of varying sizes were observed at low densities, dependent on patch coverage and density.
  • State diagrams illustrating stable phases were generated.
  • Polydispersity in patch coverage was found to affect structure polarization.

Conclusions:

  • IPCs can form various ordered 2D structures.
  • Self-assembly is tunable by controlling patch size, density, and interaction strengths.
  • This work provides a framework for designing complex colloidal structures.
