Influence of desorption-controlled interchange on dynamic surface tension excess: Calculation of kinetic desorption constant

Dilatational Properties of Poly(DL-lactic acid) and Bovine Serum Albumin Monolayers Spread at the Air/Water Interface

“…(16) Langevin, D.; Bouchiat, A. is for characteristic times in the range of 1 to 103 s. [24][25][26][27][28] In general, the viscoelastic properties of a surface film depend on the characteristic time of the perturbation, since various relaxation processes involving molecular relaxation mechanism with different characteristic times can take place.…”

Emulsions stability, from dilute to dense emulsions — Role of drops deformation

“…The authors distinguish a diffusion relaxation time of the electrical double layer and a second time-scale linked to the experimental method used (the minimum interfacial age which can be achieved with the given method; typically texp = 5 × 10 − 3 s). Let us mention here that the influence of desorption controlled interchange on dynamic surface tension and calculation of desorption kinetic constant has been published by Panayotov et al [195] already in the year 1983. Surface dilational elasticity and relaxation processes were also studied by Panayotov [196] et al [196,197], both theoretically and experimentally; they obtained very interesting results on fundamental properties of spread and adsorbed monolayers.…”

Propagation of Photoinduced Surface Pressure Perturbation along a Mixed Benzospiropyran−Octadecanol Monolayer

“…As a result of the compression of a monolayer by means of a barrier moving with a constant velocity U b (Figure A), a propagation of the local surface pressure perturbation along the monolayer occurs. A complete description of the simultaneous longitudinal motion of the monolayer and the lipid substrate was previously developed. − Without intrinsic surface dilatational viscosity or other relaxation processes the rheological behavior of an insoluble monolayer is elastic. In this simplest case, the following differential equation governs the propagation of the momentum motion along the x coordinate and describes the distribution of the surface velocity U ( x,t ) with t : Where E 0 is the surface dilatational elasticity of the monolayer, μ is the bulk viscosity, and h is the depth of the liquid subphase.

1 Schematical description of the three experimental setups: W, Wilhelmy plate; L 0 , monolayer length; h , thickness of the bulk liquid subphase; U b , barrier velocity; x i , variable distance between the Wilhelmy plate detector and the place of mechanical or photochemical perturbation; UV, ultraviolet irradiation.
