Exploring the kinetics of switchable polymer surfaces with dynamic tensiometry [PDF]
Soft Matter, 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).

Utilizing Dynamic Tensiometry to Quantify Contact Angle Hysteresis and Wetting State Transitions on Nonwetting Surfaces [PDF]
Langmuir, 2013 Goniometric techniques traditionally quantify two parameters, the advancing and receding contact angles, that are useful for characterizing the wetting properties of a solid surface; however, dynamic tensiometry, which measures changes in the net force ...

Measurement of aggregate cohesion by tissue surface tensiometry. [PDF]
J Vis Exp, 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.

Measuring very negative water potentials with polymer tensiometers: principles, performance and applications [PDF]
, 2009 In recent years, a polymer tensiometer (POT) was developed and tested to directly measure matric potentials in dry soils. By extending the measurement range to wilting point (a 20-fold increase compared to conventional, water-filled tensiometers), a ...

Surface tensiometry of phase separated protein and polymer droplets by the sessile drop method
Soft Matter, 2021 Phase separated macromolecules play essential roles in many biological and synthetic systems. We extend sessile droplet tensiometry to work with small quantities of such ultra-low surface tension droplets.
