Single‐Atom Iron‐Catalyzed Oxidative Esterification: From Methylarenes to the Upcycling of Polystyrene and Lignin‐Derived Feedstocks

open access: yesAngewandte Chemie, EarlyView.
Heterogeneous iron‐catalyzed environmentally benign and sustainable CH‐oxidative esterification methodology has been developed for the synthesis of esters. This challenging reaction has been achieved by the rational design of specific single atom iron‐based catalyst with Fe‐N4 active centers, which empowered the oxidative esterification of methyl and ...

Assessing Surgical Extent in Endoscopic Sinus Surgery: A Scoping Review of Scoring Systems

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Endoscopic sinus surgery (ESS) varies substantially in the extent of surgical dissection performed, even when described under the same procedural label. In chronic rhinosinusitis, this heterogeneity may influence postoperative outcomes, revision rates, and response to biologic therapies.

AI‐Driven Mapping of Seizure Spread Patterns

open access: yesAnnals of Neurology, EarlyView.
Objective The focus of epilepsy research has largely been on seizure onset; however, physicians typically examine the patterns of seizure spread past seizure onset as well. This study aims to align automated seizure analysis with clinical practice, leverage deep learning to standardize seizure annotations that varies among physicians, and understand ...
