0 a substance that reduces the surface tension of a liquid (= the natural force existing in a liquid that holds its surface together):
Surfactants are used, for example, as emulsifiers or in detergents.
Early versus delayed selective surfactant treatment for neonatal respiratory distress syndrome.
This property results from neglecting the surfactant diffusion.
The pediatric cardiologist was unaware which babies had received surfactant.
Here, the surfactant is swept to the back of an advancing bubble and accumulates near the rear.
In this paper we derive a simple mathematical model describing the flow of micellar surfactant solution beneath a gas-liquid interface.
Consequently, when surfactant solution flows beneath a free surface, the fluid dynamics and surface chemistry are, in general, intimately coupled.
These variables include surfactant, common radiological investigations, blood product transfusions, surgery, and echocardiography.
A candidate might be the variation of agar surface tension along the envelope due to some surfactant secreted by the bacteria.
