Colloids and Surfaces is a peer-reviewed journal of surface science. It was established in 1980. In 1993, it split into two parts Colloids and Surfaces A and Colloids and Surfaces B. The journal is published by Elsevier.
A colloid has a dispersed phase (the suspended particles) and a continuous phase (the medium of suspension). The dispersed phase particles have a diameter of approximately 1 nanometre to 1 micrometre. [2] [3] Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in
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.

Schematic of the electrical double layer (EDL) in aqueous solution at the interface with a negatively-charged surface of a mineral solid. Blue + sphere: cations; red – spheres: anions. The number of cations is larger in the EDL close to the negatively-charged surface in order to neutralize these negative charges and to maintain electroneutrality.
Unlike solutions and colloids, if left undisturbed for a prolonged period of time, the suspended particles will settle out of the mixture. Although suspensions are relatively simple to distinguish from solutions and colloids, it may be difficult to distinguish solutions from colloids since the particles dispersed in the medium may be too small ...
Within the broad field of modern colloid and surface chemistry, his research is mainly concentrated into the following areas: 1. Self-assembly of bio-inspired surfactants (nucleolipid and ascorbic acid derivatives) and of biomolecules (cyclodextrins) 2. Core-shell nanostructures with tunable magnetic properties 3.
It is universally included in text books on colloid chemistry and is still widely applied in modern studies of interparticle forces in colloids. In particular, the Derjaguin approximation is widely used in order to approximate the interaction between curved surfaces from a knowledge of the interaction for planar ones.
