WebHydrophobicity, a key concept in chemistry, is defined by IUPAC 1 as “the association of non-polar groups or molecules in an aqueous environment which arises from the tendency of water to exclude non-polar molecules”. IUPAC also defines hydrophobic interactions as “The tendency of hydrocarbons (or of lipophilic hydrocarbon-like groups in ... Webhydrophobicity determination, the results obtained led the authors to the conclusion that it was not possible to define the surface "hydrophobicity" of a bacterium other than on a …

WebHydrophobicity [12,13] is the association of nonpolar groups or molecules in an aqueous environment, which arises from the tendency of water to exclude nonpolar molecules. The hydrophobicity of the compounds in the series can be represented on a relative scale with the hydrophobic substituent constant π. In chemistry, hydrophobicity is the physical property of a molecule that is seemingly repelled from a mass of water (known as a hydrophobe). In contrast, hydrophiles are attracted to water. Hydrophobic molecules tend to be nonpolar and, thus, prefer other neutral molecules and nonpolar solvents. … Ver mais The hydrophobic interaction is mostly an entropic effect originating from the disruption of the highly dynamic hydrogen bonds between molecules of liquid water by the nonpolar solute forming a clathrate-like structure around … Ver mais Dettre and Johnson discovered in 1964 that the superhydrophobic lotus effect phenomenon was related to rough hydrophobic … Ver mais • Amphiphile – Hydrophilic and lipophilic chemical compound • Cerium(IV) oxide – chemical compound • Contact angle meter – Angle measuring instrument • Froth flotation – Process for selectively separating of hydrophobic materials from hydrophilic Ver mais Superhydrophobic surfaces, such as the leaves of the lotus plant, are those that are extremely difficult to wet. The contact angles of a water droplet exceeds 150°. This is referred to as … Ver mais Hydrophobic concrete has been produced since the mid-20th century.
