Quinoline-para-quinones and metals: coordination-assisted formation of quinoline-ortho-quinones

, 2018
Attempts to obtain quinolinedione organometallics resulted in the metal-assisted formation of quinoline-ortho-quinones after reaction with protic solvents.

Comparative Analysis of Model‐Agnostic Explanation Methods in Materials Science

Advanced Intelligent Systems, EarlyView.
To address the critical lack of explainable artificial intelligence (XAI) benchmarks in materials science, we present a quantitative and qualitative analysis of six XAI methods applied to molecular fingerprints. Our results reveal significant discrepancies in feature importance rankings, demonstrating that the chosen explanation approach introduces ...

Vacuum‐Induced Surface Reconstruction of Mn–Ce Oxides for Low‐Temperature Coupled Redox Catalysis

Angewandte Chemie, EarlyView.
Near‐surface reconstruction enhances low‐temperature redox catalysis in Mn–Ce mixed oxides. Sequential vacuum annealing and reduced‐pressure O2 treatment enrich Mn near the surface while preserving the CeO2 fluorite framework, promoting interfacial electron redistribution, oxygen activation, and redox cycling.

Freedom dreaming of migrant justice: Critical reflections on counterspaces and institutional violence in the university

American Journal of Community Psychology, EarlyView.
Abstract US universities are built on stolen land and sustained through hierarchies of power that produce what migrant justice scholars name as b/order regimes. As institutions that claim to be sites of learning and inclusion, universities are fraught with contradictions as simultaneously sites of dispossession, exclusion, and control.

Site Density Governs Switching Reactivity Regimes During Aerobic C─H Oxidation in Mn Single‐Atom Photocatalysts

Angewandte Chemie, EarlyView.
Increasing the density of isolated manganese (Mn) atoms in carbon nitride (CNx) photocatalysts does not continuously improve performance. Instead, beyond a critical loading, the polymer support reorganizes, altering charge‐carrier dynamics and oxygen activation while preserving atomic dispersion.

Should I Stay or Should I Go—Leveraging an Overlooked Feature of Click‐to‐Release Chemistry for Affinity Labeling

Angewandte Chemie, EarlyView.
Click‐to‐release (C2R) chemistry is redirected from payload liberation toward ligand‐directed covalent protein labeling through a transient dihydropyridazine methide (DHP‐methide). This concept opens the way to dual‐functional systems combining covalent target engagement with controlled effector release.

Quinones used as biomarkers for exposure to air pollution. [PDF]

, 2008
It is widely believed that particulate matter (PM) present in ambient air is responsible for a variety of health effects. The presence of quinones in ambient air has been suggested as a possible cause for the detrimental effects on human health.

Radical, Not Ionic: The Mechanochemical Zincke Nitration of Phenols

Angewandte Chemie, EarlyView.
Mechanochemistry recasts the classical Zincke nitration as an open‐shell process. Liquid‐assisted vibrational milling of phenols with in situ HNO2 delivers direct and ipso nitration across 50 substrates, while atmosphere, NOx‐transfer, EPR and DFT evidence expose a phenoxyl‐radical/NO2 manifold underlying this historically ionic transformation ...

Electrode Treatments for Redox Flow Batteries: Translating Our Understanding from Vanadium to Aqueous‐Organic

Advanced Science
Redox flow batteries (RFBs) are a promising technology for long‐duration energy storage; but they suffer from inefficiencies in part due to the overvoltages at the electrode surface.

Axial Boron Coordination Reconstructs Stereostructure of Cu Single‐Atom Nanozymes for Efficient Water‐Phase Chemical Sensing

Angewandte Chemie, EarlyView.
Sun et al. proposed an axial boron coordination strategy to reconstruct the stereostructure of Cu SAzymes and enable them to serve as efficient laccase mimics for high‐throughput smart sensor array detection of phenolic pollutants in water phases. ABSTRACT Developing single‐atom nanozymes with stereoconfigurations is a new paradigm for biomimetic ...
