An epoxy latent curing agent with outstanding storage stability and processing convenience
The latent curing of epoxy resins has long been constrained by the inherent dilemma between easy deactivation at room temperature and the demand for rapid curing at elevated temperatures, severely limiting their large-scale applications. Herein, we innovatively constructed a Mn 2...

Hydrodynamic and mass transfer behaviors of NH 3 microbubbles in ionic liquids
Abstract Ionic liquids enable efficient ammonia‐containing gas separation, but conventional absorption towers suffer from limited interfacial area and mass transfer efficiency. Microchannels overcome this owing to their large specific surface area. This study investigated the hyd...
