surfactant Usage Examples

Preposition: on

market: Risks to the environment must be outweighed by the benefits of keeping the surfactant on the market.

Adjective modifier

  • non-ionic: The Eco-Balls contain mineral oxides and act as a natural non-ionic surfactant that reduces surface tension and releases dirt.
  • anionic: In the presence of anionic surfactants, 2 detected alkaline earth metal cations more effectively than alkali metal cations.
  • cationic: Cationic surfactants have the ability to neutralize a static electric bond which holds some types of soil ( e.g. soot ) to fibers.
  • pulmonary: The surface activity of pulmonary surfactant from diving mammals.
  • synthetic: This shows clearly that synthetic surfactants reduce deaths in premature babies compared to control.
  • natural: Natural surfactant can be extracted from animal lungs or human amniotic fluid.

Converse of object

  • contain: Some contain a surfactant called sodium lauryl sulfate, which is a common cause of reactions, particularly in people with eczema.
  • use: In addition, the surfactant used in glyphosate formulations increases the likelihood of absorption through the skin.
  • produce: We have a project looking at the use of biological systems to produce surfactant.
  • give: He was intubated, commenced on IPPV and given surfactant.

Modifies a noun

  • self-assembly: Central areas of research are surfactant self-assembly, polymers in solutions, and gels and polymer interactions with surfactants.
  • adsorption: Near the nozzle tip, the surface strain rates are very large, so the surfactant adsorption is very small.
  • molecule: The surface of the particle shows a monolayer of bound surfactant molecules ( far right ).
  • protein: They looked at surfactant protein A, which is essential for normal breathing outside the womb.
  • solution: Her work on surfactant solutions led her to a job at Kodak.
  • system: The project features the world's largest lattice Boltzmann simulation of its kind, to study defect dynamics in liquid crystalline surfactant systems.

Preposition: in

  • solution: Study of bulk and surface properties of surfactants in solution will continue, in collaboration with Industry ( currently Unilever, McBrides ).
  • treatment: Natural surfactant extract vs synthetic surfactant in the treatment of established respiratory distress syndrome.

Noun used with modifier

lung: In infants born more than two months premature the quantities of lung surfactant may be greatly reduced or completely absent.
