Drainage and critical thickness of foam films from mixed solutions of bovine serum albumin and n-dodecyl-β-D-maltoside

Evolutions and equilibrium parameters of foam films from individual solutions of Bovine serum albumin, n-dodecyl-β-D-maltoside and from their mixed solutions

“…A modified interferometric method (with a video registration) [23] was employed to obtain the evolutions of foam films stabilized by pure BSA , C 12 G 2 or by their mixtures. The calculation of the film equilibrium thickness eq h ) was based on the intensity of the reflected light from the film surfaces [24]. The contact angle was calculated using r 1 and r 2 -the radii of a common film (just before a black spot formation in it) and Newtonium black film respectively and R c -radius of curvature of the liquid meniscus [23].…”
