A Naphthalene Monoimide Meisenheimer Complex as Strong Organic Hydride Donor for Metal‐Free CO2 Reduction

open access: yesChemistry – A European Journal, EarlyView.
A Meisenheimer complex derived from two‐fold reduction and protonation of naphthalene monoamide has been identified as a strong organic hydride donor which is able to reduce CO2. ABSTRACT Selective CO2 reduction to formate is challenging due to similar thermodynamics for the reaction to other products such as carbon monoxide and molecular hydrogen ...

A Low‐Oxidation‐State Mechanism for O─O Bond Formation in Photosystem II via Oxo–Hydroxyl Radical Coupling

open access: yesChemistry – A European Journal, EarlyView.
An oxo–hydroxyl radical coupling mechanism is identified for O─O bond formation in Photosystem II within the low‐oxidation‐state paradigm. Ca‐bound W3 forms Ox in the S4 state and subsequently couples with O5. The resulting hydroperoxide intermediate provides a mechanistic explanation for the poor resolution of Ox in XFEL structures.

Exploring the Synthesis of Metalloporphyrin Equipped Pd12L24 Supramolecular Spheres

open access: yesChemistry – A European Journal, EarlyView.
We expand the scope of Pd12L24 nanospheres equipped with porphyrins. Focusing on the porphyrin metallation state, synthetic strategies for porphyrin building block (BB)compounds are developed. The compounds are evaluated against nanosphere self‐assembly conditions.

Selective Non‐Catalytic Reduction of NOx in the Exhaust Gas of Small Wood Gasification Boilers

open access: yesChemie Ingenieur Technik, EarlyView.
Kinetic studies of the SNCR reaction were conducted to investigate NOx reduction in the exhaust gas of small‐scale wood gasification boilers. Both the experimental results and the derived global kinetic model indicate that SNCR can achieve a significant reduction in NOx emissions under typical operating conditions. ABSTRACT The gas‐phase reaction of NO

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Exogenous melatonin alleviates nicosulfuron toxicity by regulating the growth, photosynthetic capacity, and antioxidative defense of sweet corn seedlings

open access: yes
Improper use of nicosulfuron (NSF) may induce harmful effects on plants during weed control. Melatonin (MT) regulates photosynthetic and physiological processes in plants.

Critical mineral removal from mining‐impacted waters using microalgal biomass

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Rising demand for critical minerals has led to increased mining and mineral processing activities, resulting in the release of metal‐contaminated waters requiring treatment. Conventional treatment methods, such as lime neutralization, effectively precipitate metals; however, they are less effective at low metal concentrations and produce large

High atmospheric pressure rescues plant growth under humidity stress: A model for climate‐resilient deep underground agriculture

open access: yesDeep Underground Science and Engineering, EarlyView.
High atmospheric pressure (120 kPa) in deep underground counteracts humidity‐induced physiological stress in plants, stabilizing water balance and enhancing antioxidative defenses. This synergy boosts biomass despite elevated humidity, demonstrating sustainable deep underground agriculture potential under climate uncertainty.
