An in-depth evaluation of sample and measurement induced influences on static contact angle measurements [PDF]
Scientific Reports, 2022 Static contact angle measurements are one of the most popular methods to analyze the wetting behavior of materials of any kind. Although this method is readily applicable without the need of sophisticated machinery, the results obtained for the very same

A noise-resistant ADSA-PH algorithm for superhydrophobic surface’s static contact angle evaluation [PDF]
AIP Advances, 2017 The blur around the contact points significantly decreases the evaluated static contact angle for superhydrophobic surface which is clearly presented in the paper. To improve the accuracy in the evaluated static contact angle for superhydrophobic surface,

Distance mapping for quantifying contact surface area and inter-bone distance in wrist CT imaging: a comparative study of four methods [PDF]
Scientific ReportsWhen assessing osteoarthritis, the congruency of articular surfaces and cartilage integrity are crucial. Static or dynamic CT scanning and subsequent bone-to-bone distance mapping enables a non-invasive evaluation of these factors.

Temperature-dependence of the static contact angle: A transition state theory approach [PDF]
Journal of Colloid and Interface Science, 2021 The temperature dependence of the static contact angle could a priori be predicted by using surface tension partitioning. An original model based on the transition state theory is also introduced. This model considers thermocapillary fluctuations on the droplet surface near the triple line and the self-affine pinning of this triple line against a solid

Contact angle hysteresis and static friction for two-dimensional droplets [PDF]
Contact angle hysteresis of droplets will be examined in light of static friction between liquid drop and solid surface. Unlike frictions in solid-solid interfaces, pinning forces at contact points or contact lines would be the cause of friction. We will define coefficients of static friction and relate them with advancing and receding contact angles ...

Research on the static contact angle algorithm of raindrop
Journal of Physics: Conference SeriesAbstract In the aerospace field, the raindrop spread is inhibited. After coming into contact with the wing wall, it rapidly contracts, and the surface energy is reconverted into kinetic energy, causing the raindrop to bounce off the surface. The main characteristic parameter of superhydrophobicity is the contact angle.

A General Model for Static Contact Angles [PDF]
The problem of contact angle and hysteresis determination has direct implications for engineering applications of wetting, colloid and surface science. Significant technical challenges can arise under real-world operating conditions, because the static contact angle is strongly influenced by contamination at the liquid-solid and liquid-vapor interfaces,
