The contact angles,, of pure liquids and of ethanol + water mixtures on griseofulvin powders have been determined from the rates of liquid permeation through powder beds. The associated free energies of adhesion and immersion (Δ) were negative. The corresponding enthalpies of immersion (Δ) were measured calorimetr. Krishnan et al. carried out a systematic comparison of blood-protein adsorption using time-and-concentration-dependent tensiometry that sensitively measures either solution/air (liquid-vapor, LV) interfacial tensions or solution/surface (solid-liquid, SL) contact angles.

Contact angles and surface energetics by Daniel Yu Hing Kwok Download PDF EPUB FB2

The measurements of meaningful contact angles in terms of surface energetics are also discussed. It is shown that the apparent controversy with respect to measurement and interpretation of contact angles are due to the fact that some (or all) of the assumptions made in all energetic approaches [7–14] are violated when contact angles are Cited by: Recent progress in the correlation of contact angles with solid surface tensions are summarized.

The measurements of meaningful contact angles in terms of surface energetics are also discussed. Contact Angle, Wettability and Adhesion, Volume 4 - Kindle edition by Mittal, Kash L.

Dynamic evolution of contact angle on solid substrates during evaporation The concept, characterization, concerns and consequences of contact angles in solid-liquid-liquid systems Superamphiphobic surfaces are defined in analogy with superhydrophobic ones: on a superamphiphobic surface, both polar and nonpolar drops exhibit large (>°) static contact angles and small contact angle hysteresis (limited to few degrees).

Different approaches can be used to achieve these properties.

Often the view is expressed that water contact angle (WCA) or other wettability/surface energy measurements made on a material surface can be used to predict cellular attachment to materials, e.g., bacteria attach to hydrophobic this article, the authors present a perspective emerging from their work that has failed to find relationships between WCA and microbial and stem cell Cited by: 9.
