Orbiting Self‐Organization of Filament‐Tethered Surface‐Active Droplets

open access: yesSmall, Volume 19, Issue 20, May 17, 2023., 2023
Out‐of‐equilibrium self‐organization is demonstrated by interconnected source and drain droplets at an air‐water interface. While self‐assembled filaments grow from the source droplet, a hydrolysis reaction generates a concentration gradient around the drain droplet, which destabilizes filaments approaching the drain from behind.

Multilayer Adsorption of Heptane Vapor at Water Drop Surfaces

open access: yesColloids and Interfaces, 2017
The measured dynamic surface tension of a water drop in air saturated by heptane vapor shows a sharp decrease from about 60 mN m−1 to 40 mN m−1, and less after a certain adsorption time. The observed adsorption kinetics is analyzed by a theoretical model

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

Natural variations in the biofilm-associated protein BslA from the genus Bacillus [PDF]

open access: yes, 2017
BslA is a protein secreted by Bacillus subtilis which forms a hydrophobic film that coats the biofilm surface and renders it water-repellent. We have characterised three orthologues of BslA from Bacillus amyloliquefaciens, Bacillus licheniformis and ...

Adsorption of carboxylic modified latex particles at liquid interfaces studied by the gel trapping technique [PDF]

open access: yes, 2014
We have studied how carboxylic modified latex (CML) microparticles adsorb at liquid surfaces and the preferred type of emulsion they can stabilise depending on the particle size and the surface density of carboxylic groups.

Contact lenses wettability in vitro: effect of surface-active ingredients. [PDF]

open access: yes, 2010
PurposeTo investigate the release of surface-active agents (surfactants) from unworn soft contact lenses (SCLs) and their influence on the lens surface wettability in vitro.MethodsSurface tension (ST) of blister pack solutions was measured by pendant ...

Advances in drop and bubble profile analysis tensiometry

open access: yesCurrent Opinion in Colloid & Interface Science
Profile analysis tensiometry (PAT) with drops and bubbles is a successful methodology to characterize liquid–fluid interfaces. Questions about the most suitable size of drops and bubbles have been solved now on the basis of dimensionless numbers. The consideration of the standard deviation between measured and calculated liquid profiles as a sensitive ...

Hydrodynamic signatures of stationary Marangoni-driven surfactant transport [PDF]

open access: yes, 2017
We experimentally study steady Marangoni-driven surfactant transport on the interface of a deep water layer. Using hydrodynamic measurements, and without using any knowledge of the surfactant physico-chemical properties, we show that sodium dodecyl ...

Cooperative effects in surfactant adsorption layers at water/alkane interfaces

open access: yes, 2019
In the present work, the properties of dodecyl dimethyl phosphine oxide (C12DMPO) at the water/decane interface are studied and compared with those obtained earlier at the interface to hexane.
