A Snake-Based Approach to Accurate Determination of Both Contact Points and Contact Angles
A new method based on B-spline snakes (active contours) for measuring high-accuracy contact angles with good accuracy and applicability to a variety of images thanks to the high-quality image-interpolation model and an advanced image-energy term. Expand

The findings from this study suggest a strategy for creating surfaces that maintain their liquid repellency even after exposure to large hydrostatic pressures associated with liquid columns or jets. Expand
Nanoengineered multiscale hierarchical structures with tailored wetting properties.
Using this approach, multiscale hierarchical structures for biomimetic functional surfaces can be fabricated with precise control over geometrical parameters and the wettability of a solid surface can be tailored in a controllable manner. Expand
A roughness-based wettability switching membrane device for hydrophobic surfaces
This work presents the development of a wettability switching membrane device using the surface roughness effect. We designed and fabricated a roughness switchable membrane device, consisting of aExpand
A thermodynamic approach for determining the contact angle hysteresis for superhydrophobic surfaces.
A free energy thermodynamic analysis (of a 2-D model surface) is proposed that significantly simplifies calculations of free energy barrier associated with CAH phenomena and establishes a criterion for transition between noncomposite and composite wetting states. Expand
Contact angle measurements on superhydrophobic carbon nanotube forests: Effect of fluid pressure
In this paper the effect of pressure on the contact angle of a water drop on superhydrophobic carbon nanotube (CNT) forests is studied. Superhydrophobic CNT forests are obtained from a new and simpleExpand
Effects of hydraulic pressure on the stability and transition of wetting modes of superhydrophobic surfaces.
The underlying mechanisms of stability, metastability, or instability of the Cassie-Baxter and Wenzel wetting modes and their transitions on superhydrophobic surfaces decorated with periodic micropillars are quantitatively studied and proposals for a mixed wetting mode are proposed. Expand
Electrospun poly(styrene-block-dimethylsiloxane) block copolymer fibers exhibiting superhydrophobicity.
Calorimetric studies confirm the strong segregation between the polystyrene and poly(dimethylsiloxane) blocks and the fibers are shown by transmission electron microscopy to exhibit microphase-separated internal structures. Expand
Formation Process of Super‐Water‐Repellent Al2O3 Coating Films with High Transparency by the Sol–Gel Method
Alumina thin films with a roughness of 20 to 50 nm were formed by immersing porous alumina gel films prepared by the sol-gel method in boiling water. When hydrolyzed fluoroalkyltrimethoxysilane wasExpand
Microfabricated textured surfaces for super-hydrophobicity investigations
The natural hydrophobicity of surfaces can be enhanced if they are micro-textured. This is due to air trapped in the structure, which provides the deposited drop with a composite surface made ofExpand
