Colloids and Surfaces is a peer-reviewed journal of surface science. It was established in 1980. It was established in 1980. In 1993, it split into two parts Colloids and Surfaces A and Colloids and Surfaces B .
It is the leading journal focusing on the science and application of systems and materials in which the interface dominates structure and function. Research areas covered include surface and colloid chemistry. Langmuir publishes original research articles, invited feature articles, perspectives, and editorials.

Colloids are non-soluble particles suspended in a medium, such as proteins in an aqueous solution. [36] Research into colloids is primarily focused on understanding the organization of matter, with the large structures of colloids, relative to individual molecules, large enough that they can be readily observed. [37]
A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance. Some definitions specify that the particles must be dispersed in a liquid , [ 1 ] while others extend the definition to include substances like aerosols and gels .
To understand the formation and properties of such dispersions (incl emulsions), it must be considered that the dispersed phase exhibits a "surface", which is covered ("wet") by a different "surface" that, hence, are forming an interface (chemistry). Both surfaces have to be created (which requires a huge amount of energy), and the interfacial ...
Diagram showing the ionic concentration and potential difference as a function of distance from the charged surface of a particle suspended in a dispersion medium. Zeta potential is the electrical potential at the slipping plane. This plane is the interface which separates mobile fluid from fluid that remains attached to the surface.
This distinguishes a suspension from a colloid, in which the colloid particles are smaller and do not settle. [2] Colloids and suspensions are different from solution , in which the dissolved substance (solute) does not exist as a solid, and solvent and solute are homogeneously mixed.
