By definition, the phenomenon of hysteresis is observed when a parameter of the system, such as the volume of a drop placed on a solid, is varied back and forth, or when an external force is making the drop move in one direction (ie. by the tilting table experiment). In the present ...
Shapea complementarity, electrostatic potential, available hydrogen bond donors and acceptors, hydrophobicity, stereoelectronic effects and other properties can determine binding specificity. For any interface, some properties are critical to recognition - but different properties are essential in different ...
From the basic meaning of philicity-phobicity, θR∼90° is proposed as the new cut-off between hydrophilicity and hydrophobicity. The main driver for hydrophobicity is attributed to the high water surface tension. The merit of this proposed definition is discussed. Since wetting interaction ...
In addition, the mechanical strength, electrical conductivity, and hydrophobicity of the catalyst are also important basic macroscopic structural parameters. Nowadays, with the advancement of science and technology, the evaluation of the relatively crude macro parameters of catalysts has been left behind ...
as SEM images of hierarchical structures which consist of micro-/nano-scale layers on the upper surfaces of insect wings [1],[2]. From the nature’s plant leafs and insect wings, it is clear that the hierarchical micro-/nano-scale surfaces are essential to demonstrate super-hydrophobicity. ...
It was found that the CAs of the damaged surfaces and even the interior parts reached high values (about 148°), showing a real integral hydrophobicity. CA values for impregnation treated concrete are hardly found in the literature, though this method is based on the generation of hydrophobic...
Surface microtexturing has gradually attracted attention due to its good hydrophobicity and drag reduction properties, which has become an effective way to improve the performance of new products and reduce energy consumption. Since Hamilton and Halavit [1] first proposed to process the microstructure...
other parameters as MWCO or hydrophobicity remained unchanged (seeSection 3.1). SEM imaging confirms the development of a secondary gold layer on the membrane surface when 15 nm of gold was sputtered. Accordingly, resulting permeability decrease is presumably caused by higher filtration resistance due ...
Figure 4. Theoretical model of hydrophobicity: (a) Young’s model, (b) Wenzel structure model, and (c) Cassie–Baxter structure model. The Wenzel [21] model is based on a rough surface, considering the influence of the actual rough fabricating on the contact angle. The rough surface is...
Based on the analyses of the Washburn Function and the surface energy, it can be concluded that the spreading of water droplets along the capillary between the yarns was significantly inhibited, and the surface energy of the fabric decreased correspondingly, bringing about the most hydrophobicity of...
