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
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,

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

Precise Static Contact Angle Measurements Using Pythagolas Rule
Adhesion and Interface, 2014 Pythagolas rule was used for investigation of static contact angle in particular figures. Static contact angle measurement was important to evaluate the wettability between solid and liquid. Optimum measurement method and standardization of calculation for static contact angle were investigated for practical application. Optimum diameter of droplet for

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.

On the Dynamic Contact Angle in Capillary Flows [PDF]
Journal of Chemical and Petroleum Engineering, 2021 The displacement of the contact line (CL) between two arbitrary immiscible flowing fluids was modeled. The present model is valid for a wide range of viscosity ratios of the phases. This is while the previously developed models reported in the literature

Water-Repellency and Anisotropic Wettability of Micro-Grooved Polymer Surfaces [PDF]
한국정밀공학회지, 2020 Superhydrophobicity and anisotropic wettability can be simultaneously achieved by simple groove pattern on a surface. To verify those characteristics experimentally, we fabricated the micro-grooved surfaces with four different groove widths.

Contact angle hysteresis in a microchannel: Statics [PDF]
Physical Review Fluids, 2019 We study contact angle hysteresis in a chemically heterogeneous microchannel by tracking static meniscus configurations in the microchannel upon varying the volume of liquid. We first construct a graphical force balance similar to a previous approach by Joanny and de Gennes for this system, though here with a straight contact line.

Research on ice suppression performance of titanium alloy surface induced by nanosecond laser
Journal of Materials Research and Technology, 2022 In this study, grid-patterned titanium surfaces were induced via nanosecond laser under ambient air. Combined with the surface wettability, the ice suppression mechanism of the surface microstructure was analysed by static frost experiments and large ...
