Gel - Wikipedia A gel is a semi-solid that can have properties ranging from soft and weak to hard and tough [1][2] Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady state, although the liquid phase may still diffuse through this system [3]
What are gels? Examples, Types, and Properties - Chemistry Notes Gels are jelly-like colloidal systems in which a liquid is dispersed in a solid medium The majority of commonly used gels are hydrophilic colloidal solutions, in which a diluted solution is formed as elastic semi-solid masses under appropriate conditions
Gel | Polymer, Cross-Linking Network | Britannica Gel, coherent mass consisting of a liquid in which particles too small to be seen in an ordinary optical microscope are either dispersed or arranged in a fine network throughout the mass
Gels: Its meaning, formation, classification, and applications A gel is a colloidal system in which the dispersed phase is liquid and the dispersion medium is solid e g when warm sol of gelatin is cooled, it sets to a semi-solid mass which is a gel
Gels – solids, liquids or something else? – Science by degrees The term ‘gel’ is used to describe pretty much any material that is jelly-like (or jello-like for our American audience!) Gels are pretty common materials – many of us style our hair with hair gel, wash ourselves with shower gel, eat jelly babies and brush our teeth with gelatinous toothpaste afterwards

Gel - Simple English Wikipedia, the free encyclopedia A gel is a semi-solid substance material which usually wobbles By weight, gels are mostly liquid But gels also behave like solids They have a three-dimensional cross-linked network within the liquid It is the crosslinks in the fluid that give a gel its structure As colloids, gels are a dispersion of molecules of a liquid within a solid
Gels and hydrogels - Latest research and news | Nature Gels are materials composed of a three-dimensional crosslinked polymer or colloidal network immersed in a fluid They are usually soft and weak, but can be made hard and tough Hydrogels are gels
