A colloidal system may be solid, liquid, or gas.

The stability of a colloidal system is the capability of the system to remain as it is.

Silver and compounds containing it ( such as colloidal silver ) can be absorbed into the circulatory system and become deposited in various body tissues, leading to argyria, which results in a blue-grayish pigmentation of the skin, eyes, and mucous membranes.

Silver sulfadiazine cream ( SSD Cream ) replaced colloidal silver as the most common delivery system for using silver on the surface of burn wounds to control infection in the 1970s.

* Zeta potential, the electrokinetic potential of a colloidal system

The slight pinkish tinge caused by colloidal scattering ( the effect seen through a glass of water into which a couple of drops of milk have been mixed ) is exacerbated, and the use of artificial light -- especially fluorescent light -- upsets the color rendition of a system which the Lumière Brothers carefully balanced for use with natural daylight.

The synthesis of colloidal quantum dots is based on a three-component system composed of precursors, organic surfactants, and solvents.

The complexity of the simulations arise from the system having a large number of degrees of freedom, and from the numerous possible interparticle interactions having place, such as friction, hydrodynamic interactions, and other kinds of interparticle forces such as colloidal forces that exert attractive or repulsive forces.

Typical precursors are metal alkoxides and metal chlorides, which undergo hydrolysis and polycondensation reactions to form either a network " elastic solid " or a colloidal suspension ( or dispersion ) – a system composed of discrete ( often amorphous ) submicrometer particles dispersed to various degrees in a host fluid.

In colloidal and surface chemistry, the critical micelle concentration ( CMC ) is defined as the concentration of surfactants above which micelles form and all additional surfactants added to the system go to micelles.

** a colloidal system consists of a dispersed phase evenly intermixed with a continuous phase

In a colloidal dispersed system, small dispersed particles of the ionic lattaice exist in equilibrium with the saturated solution of the ions, i. e.

The method consists in adding to the colloidal suspension a green biopolymer able to form a gel network and characterized by shear thinning properties.

Shoe polish consists of a waxy colloidal emulsion, a substance composed of a number of partially immiscible liquids and solids mixed together.

The World Health Organization includes silver in a colloidal state produced by electrolysis of silver electrodes in water, and colloidal silver in water filters as two of a number of water disinfection methods specified to provide safe drinking water in developing countries.

The exact value of the concentration of a truly dissolved species will thus depend on the experimental conditions applied to separate it from the colloidal particles also dispersed in the liquid.

This removes the repulsive forces that keep colloidal particles separate and allows for coagulation due to van der Waals forces.

Large ferromagnetic particles can be ripped out of the homogeneous colloidal mixture, forming a separate clump of magnetic dust when exposed to strong magnetic fields.

* solid, liquid, colloidal and gas bubble phases.

Homogeneous mixtures with a dispersed phase in this size range may be called colloidal aerosols, colloidal emulsions, colloidal foams, colloidal dispersions, or hydrosols.

The smaller the size of the pore of the ultrafiltration membrane, the lower the concentration of the dispersed colloidal particules remaining in the ultrafiltred liquid.

The impetus for this development was the observation that natural rubber is produced at room temperature in dispersed particles stabilized by colloidal polymers, so the industrial chemists tried to duplicate these conditions.

The oxide suspension begins to undergo condensation reactions which result in the creation of metal oxide bridges ( either M – O – M, “ oxo ” bridges or M – OH – M, “ ol ” bridges ) linking the dispersed colloidal particles.

Particles in ferrofluids are dispersed in a liquid, often using a surfactant, and thus ferrofluids are colloidal suspensions – materials with properties of more than one state of matter.

* Coagulation, in colloid chemistry, a process in which dispersed colloidal particles agglomerate.

In addition, phase transitions in colloidal suspensions can be studied in real time using optical techniques, and are analogous to phase transitions in liquids.

The humic and fulvic acids are extracted as a colloidal sol from soil and other solid phase sources into a strongly basic aqueous solution of sodium hydroxide or potassium hydroxide.

The basic structure or morphology of the solid phase can range anywhere from discrete colloidal particles to continuous chain-like polymer networks.

Historically, colloidal silver, a liquid suspension of microscopic silver particles, was also used as an internal medication to treat a variety of diseases.

Historically, colloidal silver was also used as an internal medication to treat a variety of diseases.

A sol is a colloidal suspension of very small solid particles in a continuous liquid medium.

File: ColloidalStability. png | Examples of a stable and of an unstable colloidal dispersion.

Hydrogel ( also called aquagel ) is a network of polymer chains that are hydrophilic, sometimes found as a colloidal gel in which water is the dispersion medium.

By contrast, products sold as a dispersion are designed with a high degree of colloidal stability.

Small amounts of acrylic acid or other ionizable monomers are sometimes used to confer colloidal stability to a dispersion.

Dispersions prepared with such stabilizers typically exhibit excellent colloidal stability ( for example, dry powders may be mixed into the dispersion without causing coagulation ).

This clay suspension was most probably collected in situ from specially located illitic clay beds that produced spontaneous colloidal dispersion in rain water.

Their particles each have an electric charge which is attracted to the oppositely charged particles of the colloidal dispersion that they are breaking.

Unstable colloidal suspensions of low-volume fraction form clustered liquid suspensions, wherein individual clusters of particles fall to the bottom of the suspension ( or float to the top if the particles are less dense than the suspending medium ) once the clusters are of sufficient size for the Brownian forces that work to keep the particles in suspension to be overcome by gravitational forces.

The following description can be read between lines 1 and 9 in page 2: " The photoelectric material, such as potassium hydride, is evaporated on the aluminum oxide, or other insulating medium, and treated so as to form a colloidal deposit of potassium hydride consisting of minute globules.

A characteristic feature of this process is that colloidal particles suspended in a liquid medium migrate under the influence of an electric field ( electrophoresis ) and are deposited onto an electrode.
