See detergent; surfactant.

Encyclopedia Britannica

This does not normally occur in the lung because of the properties of its surface coating (surfactant), a complex substance composed of lipid and protein.

Encyclopedia Britannica

In its simplest form (as shown in Figure 1), the emulsion process involves stabilizing large droplets of a monomer (or monomers) in water using a soap as a surface-acting agent, or surfactant.

Encyclopedia Britannica

Surfactant causes the surface tension to change in a nonlinear way with changes in surface area.

Encyclopedia Britannica

It is involved in the synthesis, storage, transformation, and degradation of a variety of substances, including pulmonary surfactant, fibrin, and other functionally diverse molecules (i.e., histamine, angiotensin, and prostaglandins).

In 2009 scientists reported many advances in graphene synthesis, including methods of forming graphene strips by "unzipping" carbon nanotubes chemically and physically, using surfactant-guided molecular self assembly, and deoxygenating graphite oxide (an inexpensive precursor) photothermally by means of a camera flash.

Encyclopedia Britannica

Another type of thickener, the associative thickeners, are relatively low-molecular-weight polymers that form networks in mainly aqueous systems based on their surfactant-like nature.

Encyclopedia Britannica

Constantly innovating, Ecover continues to expand and improve its product range, including the development of a new eco-surfactant for use in its hard surface cleaners, meaning the range cleans as well as – or better than - the UK's leading conventional brands.

The Guardian

Daytime habits revolved around repetitively moving steel objects of varying density against and with gravity, resting inside epidermis-pigmentation capsules, and the water- and surfactant-based purification of vestments, in that order.

The New Yorker

The nanoparticle's outer scaffold mimics the properties of the substances, known as pulmonary surfactants, whose low surface tension keeps the tiny air sacs in the lungs open, thus preventing the airways from collapsing.

Expert writing Tips

Best practice

When writing about lung function, ensure to specify "pulmonary surfactant" for clarity, as the term "surfactant" alone can refer to various substances.

Common error

Avoid using "surfactant" as a blanket term without specifying its specific type or function. Be precise about the context, whether it's related to cleaning products, lung physiology, or industrial processes.

Linguistic Context

The word "surfactant" functions primarily as a noun, referring to a substance that reduces the surface tension of a liquid. As shown in Ludwig, it may also be used to refer to surface-active agents or a lipoprotein in lung tissues.

FAQs

What is the role of "surfactant" in the lungs?

In the lungs, "surfactant" reduces surface tension in the alveoli, preventing them from collapsing and allowing for efficient gas exchange.

How is "surfactant" used in cleaning products?

In cleaning products, "surfactant" helps to lower the surface tension of water, allowing it to spread more easily and lift away dirt and grease.

What are some synonyms for "surfactant"?

Some synonyms for "surfactant" include "surface active agent", "wetting agent", and "detergent".

What happens if premature babies lack "surfactant"?

Premature babies may lack sufficient "surfactant", leading to respiratory distress syndrome, where the air sacs in their lungs collapse.
