High‐Yield Synthesis of Fe‐NC Electrocatalysts Using Mg2+ Templating and Schiff‐Base Porous Organic Polymers

open access: yesAdvanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Fe─NC porous oxygen reduction electrocatalysts are prepared employing a 2,4,6‐Triaminopyrimidine‐based porous organic polymer, a Mg2+ Lewis acid, and a low‐temperature cation exchange protocol. Using the polymer precursor achieves high pyrolysis yields and results in atomically dispersed FeNx sites. The resulting catalysts feature hierarchical porosity

Nonsurgical Endodontic Retreatment of a Large Cyst‐Like Periapical Lesion With Buccal and Palatal Cortical Plate Perforations and Maxillary Sinus Involvement: A 2‐Year CBCT Follow‐Up Case Report

open access: yesClinical Case Reports, Volume 14, Issue 3, March 2026.
ABSTRACT Large cyst‐like periapical radiolucencies with cortical perforations are traditionally managed surgically. However, nonsurgical retreatment may be effective when adequate disinfection and seal are achieved. This case report describes the management of a large maxillary periapical lesion involving five endodontically treated teeth (from 21 to ...
