Enhancing the d–Electrocatalytic Activity of MXene Through Defect Engineering
Applications of MXene. ABSTRACT Due to their versatile and tunable surface and bulk chemistry, MXenes have great potential as electrocatalysts for batteries and supercapacitors. When compared with other electrocatalytic processes, in electrocatalytic reactions, MXenes could improve ion diffusion and charge transfer by either providing functional groups

We report a dual‐atomic Si–Fe–N–C catalyst synthesized from nitrogen‐rich pinecones and an Fe porphyrin precursor. The inherent Si and N in pinecones form a porous Si–N–C framework that stabilizes Fe atoms during pyrolysis, yielding robust Si–Fe dual sites.

Regulating Defect‐Coordinated Single‐Iron‐Atom Catalysts for Efficient Nitrate Reduction Reactions
This figure illustrates the ball‐and‐stick model of an asymmetric monatomic Fe─N2 catalyst and its catalytic process for converting nitrate to ammonia. Shown are the adsorption configurations of precursors and intermediates (NO3− → NO2− → NO → NH2OH → NH3) on the catalyst surface, where brown represents iron atoms, red represents oxygen atoms, dark ...

Interfacial Ru–O–W Orbital Coupling Enables Lattice Oxygen Stabilization for Enhanced Acidic OER
A RuO2/WO3 electrocatalyst with strong interfacial Ru–O–W bonds exhibits optimized Ru–O interactions, enhancing intrinsic activity and stability for acidic OER. The WO3 support modulates the electronic structure of RuO2 and promotes oxo‐intermediate deprotonation, delivering a low overpotential of 203 mV at 10 mA cm−2 and sustained operation beyond 200

ABSTRACT This study presents an analysis of caffeine content in food supplements and evaluates current regulatory frameworks against established safety guidelines. High‐caffeine products, particularly sports, and food supplements, were assessed for compliance with the safety opinion of the European Food Safety Authority (EFSA). The investigation during
