Effect of Amplitude on the Surface Dilational Visco-Elasticity of Protein Solutions [PDF]

Colloids and Interfaces, 2018
Harmonic drop surface area oscillations are performed at a fixed frequency (0.1 Hz) to measure the dilational visco-elasticity for three proteins: β-casein (BCS), β-lactoglobulin (BLG), and human serum albumin (HSA).

Thermodynamics, Kinetics and Dilational Visco-Elasticity of Adsorbed C_nEO_m Layers at the Aqueous Solution/Air Interface

Colloids and Interfaces, 2021
The adsorption behaviour of linear poly(oxyethylene) alkyl ether (CnEOm) is best described by a reorientation model. Based on a complete set of experimental data, including the adsorption kinetics, the equilibrium surface tension isotherm and the surface

Characterization of Liquid Adsorption Layers Formed from Aqueous Polymer–Surfactant Solutions—Significant Contributions by Boris A. Noskov

Colloids and Interfaces, 2023
In many modern technologies, surface-active compounds, such as surfactants, polymers, proteins, particles and their mixtures, are essential components. They change the dynamic and equilibrium properties of the inherent interfaces, which is mostly visible

A Multistate Adsorption Model for the Adsorption of C₁₄EO₄ and C₁₄EO₈ at the Solution/Air Interface

Colloids and Interfaces, 2021
The dynamic and equilibrium properties of adsorption layers of poly (oxyethylene) alkyl ether (CnEOm) can be well described by the reorientation model. In its classical version, it assumes two adsorption states; however, there are obviously surfactants ...

Study on the relationship between surface tension and dilational visco‐elasticity with foam stability

Journal of Surfactants and Detergents
AbstractThe replacement of fluorine‐free foam is imminent, but to date, no fluorine‐free foam has reached comparable fire extinguishing performance to AFFF (aqueous film forming foam). The stability of firefighting foam significantly affects its extinguishing performance.

Decompression and Fracturing Caused by Magmatically Induced Thermal Stresses

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 3, March 2023., 2023
Abstract Studies of host rock deformation around magmatic intrusions usually focus on the development of stresses directly related to the intrusion process. This is done either by considering an inflating region that represents the intruding body, or by considering multiphase deformation.

Dilatancy and Compaction of a Rate‐and‐State Fault in a Poroelastic Medium: Linearized Stability Analysis

Journal of Geophysical Research: Solid Earth, Volume 126, Issue 8, August 2021., 2021
Abstract Faults in the crust at seismogenic depths are embedded in a fluid‐saturated, elastic, porous material. Slip on such faults may induce transient pore pressure changes through dilatancy or compaction of the gouge or host rock. However, the poroelastic nature of the crust and the full coupling of inelastic gouge processes and the host rock have ...
