Regulating Defect‐Coordinated Single‐Iron‐Atom Catalysts for Efficient Nitrate Reduction Reactions

open access: yesCarbon 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 ...

Phenolic Profiling of Olive (Olea europaea L. cv. Nocellara Messinese) Samples by Comprehensive 2D Liquid Chromatography

open access: yesChemFoodChem, EarlyView.
Comprehensive RP‐LC×RP‐LC‐PDA‐MS/MS profiling reveals 52 phenolic compounds across olive drupes, leaves, pomace, and extra virgin olive oil, highlighting matrix‐specific distribution patterns. Oleuropein derivatives dominate drupes, while flavonoids are enriched in leaves.

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

open access: yesChemistry – 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 ...

Late‐Stage Phenylation From [13C6] and [2H5]Benzene: A Versatile Tool for Stable Isotope Labeled MS Standards

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT We explored aryl thianthrenation as a tool for directly incorporating multiple isotopes into molecular scaffolds starting from full isotopically labeled benzene. Stable isotope‐labeled (SIL) molecules are indispensable tools for investigating chemical and biological mechanisms and quantifying metabolites.

Utilization of Waste Materials Using the Müller–Kühne Process—A Life Cycle Inventory Study

open access: yesChemie Ingenieur Technik, EarlyView.
This study presents a Life Cycle Inventory of the Müller–Kühne process (MKP), which converts gypsum waste into sulfuric acid and cement clinker. The MKP outperforms conventional cement production regarding material yield, though its specific energy demand is higher. Consequently, potentials for circular gypsum waste utilization are discussed.

Revisiting acidulation for tall oil and lignin manufacturing

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production
