Understanding the surface tension properties of aqueous surfactants and polymer materials is important for the pharmaceutical, coatings, paints, inks, surfactant and household products industries. The ...

DURING a voyage off southern California near Santa Catalina Island some surface tension measurements were made on the open sea and over and around the slick areas associated with kelp beds. The usual ...

A tensiometer is an instrument used to measure the surface tension (γ) of liquids or surfaces in the domain of physics. Surface tension is the contractive quality of the surface of a liquid that ...

Dyne Testing, an Intertronics brand, presents the Sigma 702 Force Tensiometer from Biolin Scientific, a standalone instrument for precise surface tension and interfacial tension measurement. The Sigma ...

Introduction Have you ever noticed on a rainy day how water forms droplets on a window? Why does it do that instead of spreading out evenly over the whole surface? You might not guess it but this ...

The researchers used the new sensor to measure the surface tension of a liquid by measuring the retraction force when a miniature cylinder was removed from water (left) and isopropyl alcohol (right).

Irregularities on a surface determine how rough it is. Surface roughness can be evaluated by visual appearances and tactile sensation and can be measured using a numerical scale. A surface condition ...

Water has very unique properties, and this experiment puts them to the test! Follow along with ABC11 Science Club with BASF and discover how to measure surface tension using a simple penny! Objective: ...
