The Colloidal State01:29

The Colloidal State

The formation of a colloidal system is exemplified by an aqueous solution containing Cl− ions is introduced to another containing Ag+ ions, resulting in the precipitation of solid AgCl as extremely tiny crystals. Instead of settling out as a filterable precipitate, these crystals remain suspended in the liquid, showcasing a colloidal system.A colloidal system involves colloidal particles within the approximate range of 1 to 1000 nm in at least one dimension, dispersed in a medium called the...
Colloidal precipitates01:09

Colloidal precipitates

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...

Colloids

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...
Recrystallization: Solid–Solution Equilibria01:10

Recrystallization: Solid–Solution Equilibria

Recrystallization is a purification technique used to separate impurities from solid compounds. In this technique, no chemical reactions occur. Instead, it exploits physical properties only, specifically, the solubility differences between the desired compound and impurities, either at a single temperature or at different temperatures, and under other selected conditions. The solid-solution equilibrium (solubility equilibrium) of each component in the solution represents a binary phase...

Area of Science:

  • Colloidal science
  • Materials science
  • Condensed matter physics

Background:

  • Colloidal systems offer model platforms for studying phase transitions.
  • Understanding crystallization in two-dimensional (2D) systems is crucial for materials design.

  • To explore dynamic heterogeneity and solidification mechanisms during freezing.

Main Methods:

  • Utilized video microscopy to observe crystallization of diameter-tunable microgel spheres in monolayers.
  • Experimentally tested four distinct 2D criteria for freezing: Hansen-Verlet rule, Lowen-Palberg-Simon criterion, radial distribution function analysis, and Voronoi polygon shape factor distribution.
  • Analyzed orientational order parameter fluctuations and percolation transitions.

Main Results:

  • Successfully induced homogeneous freezing of 2D colloidal liquids into polycrystalline solids.
  • Demonstrated the applicability of Hansen-Verlet, Lowen-Palberg-Simon, radial distribution function, and Voronoi polygon criteria to polycrystalline freezing.
