Introduction to Schiff Base

open access: yes, 2023
When any primary amine reacts with an aldehyde or a ketone under specific conditions, Schiff bases are formed. The general structure of Schiff base is R2C∙NR′ and is considered as a subclass of imines which is commonly used as a synonym for azomethine.

Strong Fully Reprocessable Engineered Wood Composites

open access: yesAdvanced Materials, EarlyView.
Engineering a hyperbranched adhesive with complementary imine‐bond and hydrogen‐bond networks, combining it with wood particles to fabricate the wood composite (WP/HTP) under mild hot‐pressing conditions. The WP/HTP exhibits 100% mechanical strength recovery after three cycles of reprocessing, and the reprocessed modulus of rupture (MOR) and modulus of
