Synergistic Fe–Si Dual‐Site Pathway Engineering in Biomass‐Derived Carbon Matrix for High‐Performance Oxygen Reduction Reaction

Carbon Energy, EarlyView.
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

Carbon Energy, EarlyView.
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

Carbon Energy, EarlyView.
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

Caffeine Content Assessment in Beverages and Food Supplements: Regulatory Challenges and Health Implications

ChemFoodChem, EarlyView.
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

Expanding the Toolbox for Inducible Protein Expression With Automation‐enabled Generation of Glycomimetics

Chemistry – A European Journal, EarlyView.
Inducible protein expression is a cornerstone of many aspects of industrial and molecular biotechnological processes. 2′‐fucosyl isopropyl‐β‐D‐thiogalactopyranose (2′F‐IPTG) and 2′‐fucosyl isobutyl‐C‐galactoside (2′F‐IBCG) mimics were explored for protein expression studies.

Eco‐Friendly Synthesis of Cobalt Phthalocyanine for High‐Efficiency CO2${\rm CO}_{2}$ Electroreduction

Chemistry – A European Journal, EarlyView.
A sustainable synthesis of cobalt phthalocyanine (CoPc) using low‐impact solvents yields high‐performance electrocatalysts with reduced waste (E‐factor 18.6). When integrated into gas diffusion electrodes, CoPc achieves up to 12% Faradays efficiency for CO2‐to‐methanol and 65% CO2‐to‐CO conversion, aligning with state‐of‐the‐art materials and enabling ...
