During biosynthesis, a globular protein folds into a tight particle with an interior core that is shielded from the surrounding solvent. The hydrophobic effect is thought to play a key role in mediating this process: nonpolar residues expelled from water engender a molecular interior where they can be buried.
WebInks are formulated using four main components: pigments, binders, solvents and additives. Pigments are used to create color impressions and optical effects. Binders keep the pigments evenly dispersed and bind them to the surface of the substrate. Solvents increase the flow characteristics and viscosity of the ink to ensure processability ...

WebApr 1, 2015 · The uniquely functional cosolvent N-methyl-pyrrolidone (NMP) iswell suited for use in waterborne polyurethane dispersions (PUDs). The use of cosolvents during polyurethane dispersion production is often necessary to enable a smooth reaction between the hydrophilic diol components [e.g., dimethylolpropionic acid (DMPA)] and the more …
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. Because water … See more 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 … See more Dettre and Johnson discovered in 1964 that the superhydrophobic lotus effect phenomenon was related to rough hydrophobic … See more • Amphiphile – Hydrophilic and lipophilic chemical compound • Cerium(IV) oxide – chemical compound See more • What are superhydrophobic surfaces?
