Interfacial tensiometry and dilational surface visco-elasticity of biological liquids in medicine
Advances in Colloid and Interface Science, 2018Dynamic surface tensions and dilational visco-elasticity are easy accessible parameters of liquids. For human body liquids, such as urine, blood serum, amniotic fluid, gastric juice, saliva and others, these parameters are very characteristic for the health status of people.

Potential controlled tensiometry of model surfaces
Journal of Colloid and Interface Science, 1989Abstract A new tensiometric method is described for determining the contact angle between a probe liquid, a gas phase, and an electroconductive solid (such as metals or organic electroconductive polymers) at varying electrical potentials of the solid phase.

The surface adsorption of n-dodecyl phosphocholine (C12PC) has been characterised by a combined measurement of surface tension and neutron reflectivity. The critical micellar concentration (CMC) was found to be 0.91 mM at 25 degrees C in pure water. At the CMC, the limiting area per molecule (A(cmc)) was found to be 52+/-3 A2 and the surface tension ...

Probing the Gelatin–Alkylammonium Salt Mixed Assemblies through Surface Tensiometry and Fluorimetry
The Journal of Physical Chemistry B, 2018The interactions, nature of the organization, and physicochemical properties of alkyltrimethylammonium bromide (C nTAB, n = 12, 14, and 16)-gelatin mixed assemblies were investigated by UV-visible spectrometry, surface tensiometry, and fluorimetry techniques.

The standard technique for measuring surface or interfacial tension by drop profile analysis requires two main steps: (i) acquisition of drop/bubble images and determination of the profile coordinates via edge detection techniques; (ii) fitting of the theoretical drop/bubble profile to the experimental coordinates using the interfacial tension gamma as

The effect of Escherichia coli (E. coli) cells on two phospholipids [dipalmitoyl phosphatidylcholine (DPPC) and dimyristoyl phosphatidylcholine (DMPC)] monolayers at the surface of a 1.5 wt% NaCl salt solution has been investigated using surface tension measurement and Brewster angle microscopy.

Surface Tensiometry Approach to Characterize Cosmetic Products in the Beauty Sector
2021The term “surface” of a material indicates the interface between a solid or liquid and the air and the term “tensiometry” represent an analytical technique capable to characterize the surface free energy of a solid and the surface tension of a liquid. The new term “surface tensiometry” indicates the analytical technique capable to characterize surface ...

At low surfactant concentration the loss of molecules in the bulk phase due to adsorption can be significant if the surface-area-to-bulk-volume ratio is large. This loss of molecules, however, can be used to determine the adsorption of a surfactant if the experiments are performed under well-controlled conditions.

Measurement of Intercellular Cohesion by Tissue Surface Tensiometry
2014Intercellular adhesion plays a vital role in many biological processes including embryonic development, malignant invasion, and wound healing, and can be manipulated to generate complex structures in tissue engineering applications. Accurate measurement of the strength of intercellular adhesion is not trivial and requires methods rooted in sound ...
