The Nonadiabatic Nature of the Substituent Effects in Azobenzene

Angewandte Chemie International Edition, EarlyView.
Unified nonadiabatic switching: thermal Z→E isomerization of para‐substituted azobenzenes proceeds through a single nonadiabatic rotational pathway. The iconic bell‐shaped Hammett plot is a σp artifact, not a reflection of a mechanistic change, exposing the limits of single‐reference density functional theory (DFT) and establishing activation entropy ...

Synthesis of an Enzyme‐Triggered Chitosan‐Based Drug Delivery System for Peri‐Implantitis Prevention

Chemistry – A European Journal, EarlyView.
ABSTRACT Dental implants have become a leading solution for tooth loss, yet bacterial infections remain a major complication. Antibacterial implant coatings are an important approach to reduce or prevent bacterial infections at the implant. Given the oral cavity's complex microbiome and the importance of some commensal bacteria, it is crucial to ...
