Colloids

19.5K
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...

Colloidal precipitates

2.7K
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...

Coagulation01:06

Coagulation

631
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...

Area of Science:

  • Materials Science
  • Nanotechnology
  • Physical Chemistry

Background:

  • Nanocrystal gels offer unique properties but are often formed via irreversible aggregation, limiting their dynamic reconfiguration.
  • Existing gelation strategies for larger particles face challenges when translated to the nanoscale due to molecular size considerations.

Purpose of the Study:

  • To review recent advancements in assembling tunable nanocrystal gels guided by equilibrium principles.
  • To explore strategies for reversible nanocrystal gel formation and control over their structure and properties.
  • To highlight the role of theoretical models and simulations in guiding experimental design.

Main Methods:

  • Assembly via reversible chemical bonding between functionalized nanocrystals and linker molecules.
  • Assembly via polymer-induced depletion attractions, creating reversible nanocrystal attractions.
  • Application of statistical thermodynamic theory and computer simulations to model assembly processes.

Main Results:

  • Demonstrated two primary strategies for reversible nanocrystal gel assembly: chemical bonding and depletion attractions.
