Acoustofluidic dynamic interfacial tensiometry
The Journal of the Acoustical Society of America, 2021The interfacial tension (IFT) of fluids plays an essential role in industrial, biomedical, and synthetic chemistry applications; however, measuring IFT at ultralow volumes is challenging. Here, we report a novel method for sessile drop tensiometry using surface acoustic waves (SAWs).

Microfluidic interfacial tensiometry
Applied Physics Letters, 2005A microfluidic approach to measure interfacial tension σ of immiscible fluids rapidly is reported. This method rests upon quantitative real-time analysis of two-phase flow and drop-shape dynamics. Drops of prescribed dimension and spacing are produced, accelerated, and deformed under extensional flow.

A New Method of Wound Tensiometry
Archives of Surgery, 1962Introduction One of the surprising facets of wound-healing investigations is the fact that the workers in the field have been unable to agree upon a standard tensiometric technique. This is unfortunate, as it makes it difficult to compare reported results adequately, since many are reported in grams or other weight units, while others are stated in ...

Publisher Summary This chapter presents after a short reminder of thermodynamic definitions, the most commonly used techniques for surface tension measurements with some details of the most interesting of them for high temperature applications. Some recent results on the evaluation of the influence of external factors, like the surrounding atmosphere,

Microfluidic ultralow interfacial tensiometry with magnetic particles
Lab Chip, 2013We describe a technique that measures ultralow interfacial tensions using paramagnetic spheres in a co-flow microfluidic device designed with a magnetic section. Our method involves tuning the distance between the co-flowing interface and the magnet's center, and observing the behavior of the spheres as they approach the liquid-liquid interface-the ...

Stripper for Bubble‐Free Tensiometry
Soil Science Society of America Journal, 1993Abstract Unwanted formation of air bubbles in the liquid water inside soil water tensiometers has always been a major nuisance afflicting this simple, fast, and accurate device. The stripper, a plastic wall (usually just a tubing wall) between the tensiometer water and a wet vacuum (containing some droplets of liquid water), strips ...
