Determining the surface energy of powders via washburn method
In this application note, the wettability of silica powder with various wetting liquids is assessed using a tensiometer of the DCAT series by DataPhysics Instruments and its corresponding software.

Measuring imaginary dynamic contact angles on dental implants using DataPhysics DCAT series
The tensiometers of the DCAT series with their dedicated software are able to determine imaginary contact angles reliably and reproducibly. This is a precious extension of the dynamic contact angle measurement method as it opens up the possibility to easily study hyperhydrophilic materials and, notably, to quantitatively distinguish the results also in cases where conventional methods always yield contact angles of 0°.

Effectiveness of surface treatment techniques for dental implants using imaginary dynamic contact angle measurements
To study ultra-hydrophilic surfaces, imaginary contact angle measurements have evolved into a powerful technique. Tensiometers of the DCAT series are the only measuring systems so far which feature a reliable and reproducible imaginary contact angle determination in their software. This method is presented on samples of UV and plasma treated dental implants.

Surface energy determination on thin wires using picolitre drops
The surface energies of a tinned and a pure copper wire were determined measuring contact angles with various liquids using the DataPhysics optical contact angle measuring and contour analysis system OCA 200 in combination with the picolitre dosing system PDDS.
