Tensiometric investigation of the interaction and phase separation in a polymer mixture–ionic surfactant ternary system [PDF]

open access: yesJournal of the Serbian Chemical Society, 2010
The interaction and phase separation in a ternary mixture composed of hydroxypropyl methyl cellulose (HPMC), sodium carboxymethyl cellulose (NaCMC), and sodium dodecylsulfate (SDS) were investigated by tensiometry.

Exploring the kinetics of switchable polymer surfaces with dynamic tensiometry [PDF]

open access: yes, 2013
Switchable polymer multilayer coatings consisting of poly(vinyl alcohol) (PVA) and poly(acrylic acid) (PAA) were prepared via Layer-by-Layer (LbL) assembly and post-functionalized with poly(ethylene glycol methyl ether) (PEG).

Surface active properties of lipid nanocapsules.

open access: yesPLoS ONE, 2017
Lipid nanocapsules (LNCs) are biomimetic nanocarriers used for the encapsulation of a broad variety of active ingredients. Similar to surface active compounds, LNCs contain both hydrophilic and hydrophobic parts in their structure.

A comprehensive study of physical, antimicrobial and emulsifying properties of self-assembled chitosan/lecithin complexes produced in aqueous media

open access: yesFuture Foods, 2021
Demand for products containing natural compounds has grown in recent decades and synthetic emulsifiers probably will be replaced. Lecithin is a natural emulsifier, but it has low emulsifying capacity for stabilizing oil-in water emulsions and does not ...

Lecithin-sodium caseinate self-assembled complexes as emulsifying agents in oil-in-water emulsion: Acidic medium approach

open access: yesCurrent Research in Food Science, 2022
Surfactant-polyelectrolyte complexes (SPECs) based on lecithin and sodium caseinate were produced and the effects of such binding on the physical, chemical and emulsifying properties were evaluated and compared with the two ingredients in isolation ...

Spontaneous wettability patterning via creasing instability [PDF]

open access: yes, 2015
Surfaces with patterned wettability contrast are important in industrial applications such as heat transfer, water collection, and particle separation. Traditional methods of fabricating such surfaces rely on microfabrication technologies, which are only

Tensiometry in fractured rocks [PDF]

open access: yes, 2000
Tensiometers are commonly used under both laboratory and field conditions for measuring the water pressure in variably saturated porous and fractured media. In order to improve our understanding of tensiometer measurement physics, we present a concept of tensiometry, analyze the results of laboratory and field infiltration tests in fractured basalt ...

Measurement of Aggregate Cohesion by Tissue Surface Tensiometry [PDF]

open access: yesJournal of Visualized Experiments, 2011
Rigorous measurement of intercellular binding energy can only be made using methods grounded in thermodynamic principles in systems at equilibrium. We have developed tissue surface tensiometry (TST) specifically to measure the surface free energy of interaction between cells.
