Fast reaction limit of a three-component reaction–diffusion system

open access: yesJournal of Mathematical Analysis and Applications, 2011
The authors consider a three-component reaction-diffusion system with a reaction rate parameter, and investigate its singular limit as the reaction rate tends to infinity. The limit problem is given by a free boundary problem, which possesses three regions separated by the free boundaries.

A Nanovessel-Catalyzed Three-Component Aza-Darzens Reaction [PDF]

open access: yesJournal of the American Chemical Society, 2020
It has been previously demonstrated that nanovessels can be highly competent catalysts providing high rate accelerations and unique selectivity to the organic transformations which they mediate. However, for supramolecular assemblies to be considered a standard reagent in organic synthesis they must first demonstrate the ability to catalyze ...
