Surface science is the study of physical and chemical phenomena that occur at the interface of two phases, including solid–liquid interfaces, solid–gas interfaces, solid–vacuum interfaces, and liquid–gas interfaces. It includes the fields of surface chemistry and surface physics. Some related practical applications are classed as surface engineering. The science encompasses concepts such as heterogeneous catalysis, semiconductor device fabrication, fuel cells, self-assembled monolayers, and adhesives. Surface science is closely related to interface and colloid science. Interfacial chemistry and physics are common subjects for both. The methods are different. In addition, interface and colloid science studies macroscopic phenomena that occur in heterogeneous systems due to peculiarities of interfaces.
Boris Vladimirovich Derjaguin was a Soviet and Russian chemist. As a member of the Russian Academy of Sciences, he laid the foundation of the modern science of colloids and surfaces. An epoch in the development of the physical chemistry of colloids and surfaces is associated with his name.
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.
The Beilstein Journal of Organic Chemistry is a peer-reviewed open-access scientific journal established in 2005. It is published by the Beilstein Institute for the Advancement of Chemical Sciences, a German non-profit foundation. The editor-in-chief is Peter Seeberger.
Langmuir is a peer-reviewed scientific journal that was established in 1985 and is published by the American Chemical Society. 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.
The Max Planck Institute of Colloids and Interfaces is located in Potsdam-Golm Science Park in Golm, Potsdam, Germany. It was founded in 1990 as a successor of the Institute for Physical Chemistry and for Organic Chemistry, both in Berlin-Adlershof, and for Polymer Chemistry in Teltow. In 1999, it transferred to newly constructed extension facilities in Golm. It is one of 80 institutes in the Max Planck Society (Max-Planck-Gesellschaft).
A streaming current and streaming potential are two interrelated electrokinetic phenomena studied in the areas of surface chemistry and electrochemistry. They are an electric current or potential which originates when an electrolyte is driven by a pressure gradient through a channel or porous plug with charged walls.
In surface science, a double layer is a structure that appears on the surface of an object when it is exposed to a fluid. The object might be a solid particle, a gas bubble, a liquid droplet, or a porous body. The DL refers to two parallel layers of charge surrounding the object. The first layer, the surface charge, consists of ions which are adsorbed onto the object due to chemical interactions. The second layer is composed of ions attracted to the surface charge via the Coulomb force, electrically screening the first layer. This second layer is loosely associated with the object. It is made of free ions that move in the fluid under the influence of electric attraction and thermal motion rather than being firmly anchored. It is thus called the "diffuse layer".
Interface and colloid science is an interdisciplinary intersection of branches of chemistry, physics, nanoscience and other fields dealing with colloids, heterogeneous systems consisting of a mechanical mixture of particles between 1 nm and 1000 nm dispersed in a continuous medium. A colloidal solution is a heterogeneous mixture in which the particle size of the substance is intermediate between a true solution and a suspension, i.e. between 1–1000 nm. Smoke from a fire is an example of a colloidal system in which tiny particles of solid float in air. Just like true solutions, colloidal particles are small and cannot be seen by the naked eye. They easily pass through filter paper. But colloidal particles are big enough to be blocked by parchment paper or animal membrane.
ACS Applied Materials & Interfaces is a peer-reviewed scientific journal that was established in 2009 by the American Chemical Society. Originally published monthly, the journal became biweekly in 2013 and weekly in 2015. The current editor-in-chief is Kirk S. Schanze. The journal covers research on advanced active and passive electronic/optical materials, coatings, colloids, biomaterials and bio-interfaces, polymers, hybrid and composite materials; and friction and wear.
Evaporation suppressing monolayers are materials that when applied to the air/water interface, will spread and form a thin film across the surface of the water. The purpose of these materials is to reduce evaporative water loss from dams and reservoirs.
The Journal of Colloid and Interface Science is a peer-reviewed scientific journal published by Elsevier. It covers research related to colloid and interface science with a particular focus on colloidal materials and nanomaterials; surfactants and soft matter; adsorption, catalysis and electrochemistry; interfacial processes, capillarity and wetting; biomaterials and nanomedicine; and novel phenomena and techniques. The editor-in-chief is Martin Malmsten. The journal was established in 1946 as Journal of Colloid Science. It obtained its current name in 1966.
Milliana Kroumova Kaisheva was a Bulgarian physical chemist, internationally known for her work in electrochemistry and colloid chemistry.
Current Opinion in Colloid & Interface Science is a bimonthly peer-reviewed scientific journal published by Elsevier. It covers the field of physical chemistry, especially research on colloids and interfaces. The journal was established in 1996 and the editors-in-chiefs are Dganit Danino and Marie Pierre Krafft.

The Zisman plot the graphical method of the Zisman theory or the Zisman method for characterizing the wettability of a solid surface, named for the American chemist and geophysicist, William Albert Zisman (1905–1986). It is a prominent Sessile drop technique used for characterizing liquid-surface interactions based on the contact angle of a single drop of liquid sitting on the solid surface.
Milton Kerker was an American physical chemist and former professor at Department of Chemistry at Clarkson University. He is best known for his work on aerosol, interface and colloid science, as well as for pioneering surface-enhanced Raman spectroscopy. Kerker effect in optics is named after him.
Emmie Helena Lucassen-Reynders was a Dutch scientist specialising in colloid chemistry and theoretical physics. She worked in both academia and in industry.
