Formation of frost phase chan
WebMar 29, 2024 · DKP (diketopiperazine) formation is a ubiquitous side reaction in SPPS (solid-phase peptide synthesis) that is highly sequence-dependent. Secondary amino acids are extremely prone to host such a side reaction. DKP formation is predominantly induced at the Fmoc (fluorenylmethyloxycarbonyl)-removal step mediated by a secondary amine, … Webence. The frost layer significantly alters the interfacial prop-erties of the original superhydrophobic surface; the frost-coated hydrophobic posts are hydrophilic and the surface loses its superhydrophobic properties. Apart from the desub-limation mechanism described here, another common mechanism for frost formation is condensation …
