WitrynaSEM observation indicates that MOF crystals grown from oriented Cu (OH) 2 nanobelts are oriented in three dimensions ( x, y and z direction), while randomly oriented Cu (OH) 2 nanobelts yield MOF crystals only oriented perpendicular to the surface ( z -direction) without in-plane orientation. WitrynaAny general reaction in organic chemistry can be written as: Substrate + Reagent → Product Where the substrate is an organic molecule to which we add the reagent. Based on the ability to either donate or abstract electrons, the reagents can be classified as: Electrophiles Nucleophiles Electrophiles
