Colloids and Suspensions

Colloids and Suspensions

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

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...

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...

Coagulation

Coagulation

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:

Environmental Science
Colloid Science
Image Processing

Background:

Colloids and nanoparticles are increasingly prevalent in surface and subsurface environments.
Colloid presence impacts contaminant transport and groundwater quality, necessitating accurate detection methods.

Purpose of the Study:

To evaluate various image processing techniques for accurate colloid detection in microscopy images.
To develop an improved colloid detection method for porous media research.

Main Methods:

Four categories of image processing methods were applied: segmentation-based, background-detection-based, filter-based, and morphology-based.
Eight specific methods were analyzed for their advantages and disadvantages.
An ensemble approach using a majority vote of the top three methods was proposed.

Main Results:

Morphology-based methods demonstrated the highest detection performance, especially for small colloids.
The proposed ensemble approach achieved perfect scores across all evaluation criteria (Precision, Recall, F-measure, TCR).

Conclusions:

Image processing methods are highly accurate for colloid recognition.
The developed ensemble approach offers superior colloid detection accuracy for porous media studies.
