Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

Advanced Engineering Materials, EarlyView.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere

Advanced Engineering Materials, EarlyView.
A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

The effect of serum, glucocorticoids, gender and gestational age on the inactivation, synthesis and secretion of surfactant phospholipids by cultured foetal rat type II pneumocytes

, 2010
Type II pneumocytes are responsible for the synthesis and secretion of pulmonary surfactant, which lines the alveoli of the lungs. Its presence as a monolayer at the airliquid interface in the alveoli diminishes surface tension, thus reducing the ...

Latherin: a surfactant protein of horse sweat and saliva [PDF]

, 2009
Horses are unusual in producing protein-rich sweat for thermoregulation, a major component of which is latherin, a highly surface-active, non-glycosylated protein.

Lung Surfactant [PDF]

Environmental Health Perspectives, 1984
Aspects of pulmonary surfactant are reviewed from a biochemical perspective. The major emphasis is on the lipid components of surfactant. Topics reviewed include surfactant composition, cellular and subcellular sites as well as pathways of biosynthesis of phosphatidylcholine, disaturated phosphatidylcholine and phosphatidylglycerol.
