Uncertainties in contact angle goniometry
Soft Matter, 2019 Contact angle measurements on superhydrophobic surfaces can have uncertainties of many degrees due to difficulties in positioning the baseline. The uncertainty depends on the goniometer image resolution.

Wetting Transitions and Contact Angles
Europhysics Letters (EPL), 1987 The wetting transition is revisited by looking at the contact angle of a macroscopic droplet, in a microscopic statistical-mechanical study, for anisotropic media. As an example, we consider the (1 + 1)-dimensional continuous SOS model with a contact wall potential, which is exactly solvable.

The Case Studies of Varied Switches for the Varied Wheel Profiles of the Railway Vehicle in Terms of the Derailment Phenomena [PDF]
International Journal of Railway Research, 2015 The flange climb derailment is one of the cause of derailment for a typical switch. The derail Insert Page Break for Printingment for the switch is a complex phenomenon since the contact area is changing dynamically.

Small-scale contact angle mapping on undisturbed soil surfaces
Journal of Hydrology and Hydromechanics, 2013 Research of the last years pointed out that most soils are neither completely hydrophilic nor hydrophobic, but exhibit a subcritical level of water repellency (i.e. contact angle, CA > 0° and < 90°).
