Influence of the Surface Viscosity on the Breakup of a Surfactant-Laden Drop [PDF]
We examine both theoretically and experimentally the breakup of a pendant drop loaded with an insoluble surfactant. The experiments show that a significant amount of surfactant is trapped in the resulting satellite droplet.

Surfactant substitution in the newborn by application of artificial surfactant [PDF]
A protein-free artificial surfactant (ALEC) composed of two phospholipids when given as a prophylactic treatment at birth to very premature babies in randomized controlled trials. It was shown to reduce the severity of RDS, the ventilator pressure, the inspired oxygen requirements, the compliance of the respiratory system, the neonatal mortality and ...

Is gastric surfactant related to lung surfactant? Reply [PDF]
Editor,—In his leading article Hills reviews important concepts about a “hydrophobic mucosal barrier” as the main biological basis for protecting the stomach against acid mediated damage to the mucosa ( Gut 1996; 39: 621–4). While we support the author’s view that lipid rather than mucus makes the gastric surface less vulnerable to protons, the ...

Role of organosilicone surfactant in apple scab control under scab conducive weather conditions
Fungicides of integrated fruit production (dithianon, captan, and diclofluanid) and an organosilicone surfactant were compared in spray schedules from green tip until summer in order to control apple scab caused by Venturia inaequalis and to evaluate ...

Effects of Surfactant Solubility on the Hydrodynamics of a Viscous Drop in a DC Electric Field
The physico-chemistry of surfactants (amphiphilic surface active agents) is often used to control the dynamics of viscous drops and bubbles. Surfactant sorption kinetics has been shown to play a critical role in the deformation of drops in extensional ...

Complexation of DNA with Cationic Surfactant
Transfection of an anionic polynucleotide through a negatively charged membrane is an important problem in genetic engineering. The direct association of cationic surfactant to DNA decreases the effective negative charge of the nucleic acid, allowing the

The influence of natural pulmonary surfactant on the efficacy of siRNA-loaded dextran nanogels [PDF]
Aim: Topical administration of siRNA nanocarriers is a promising approach in the treatment of pulmonary disorders. Pulmonary surfactant, covering the entire alveolar surface of mammalian lungs, will be one of the first interfaces that siRNA nanocarriers ...
