Fig. 10From: Structural and functional stability of the sulfur-free surfactant protein B peptide mimic B-YL in synthetic surfactant lipidsAverage surface tension values of dynamic cycles (20/min) at captive bubble surfactometry of 3 B-YL surfactant preparations produced in 2017 and re-measured in 2020. Area reduction to reach a minimum surface tension < 2 mN/m and hysteresis were essentially unchanged after 3 years of refrigerated storageBack to article page
