The In Situ Electrochemical−Chemical Cascade Strategy for Pyruvic Acid Synthesis

Advanced Science, EarlyView.
By employing an “unsaturation−oxygen coordination engineering” strategy, the local coordination environment is regulated to achieve efficient electrochemical synthesis of H2O2. Importantly, an electrochemical−chemical coupled cascade strategy is utilized for the efficient preparation of pyruvic acid via lactic acid oxidation. ABSTRACT Hydrogen peroxide

Quenching of quercetin quinone/quinone methides by different thiolate scavengers: stability and reversibility of conjugate formation

, 2003
Oxidation of flavonoids with a catechol structural motif in their B ring leads to formation of flavonoid quinone/quinone methides, which rapidly react with GSH to give reversible glutathionyl flavonoid adducts.

Conjugated Polymer‐Microbe Interactions Trigger Regulatory Reprogramming for Enhanced Bioelectrocatalysis

Advanced Science, EarlyView.
Conjugated polymer‐supported bioelectrochemical systems are shown to enhance microbial electrosynthesis by triggering coordinated electrochemical, transcriptional, post‐transcriptional (sRNA), metabolic, and protein‐level responses. Integrated multi‐omics and electrochemical analyses reveal selective physiological remodeling associated with improved ...

Unlocking Zenith Electronic State of Ni Sites in Ligand‐Engineered COFs for Efficient •O2−‐Driven Uranium Photoreduction

Advanced Science, EarlyView.
We develop a ligand engineering strategy to construct Ni‐diketimine‐linked COFs with precisely tuned Ni electronic states. By varying the coordinated diketone units, we achieve an optimal electronic configuration that enhances O2 adsorption and lowers the energy barrier for •O2− generation.

Concurrent Photooxidation and Photoreduction of Catechols and Para-Quinones by Chlorophyll Metabolites

Photochem
Photosynthesis is initiated when the sun’s light induces electron transfer from chlorophyll to plastoquinone, a para-quinone. While photosynthesis occurs in the intact chloroplasts of living plants, similar photochemical reactions between dietary ...

Stimulation of OGG1 Enhances Oxidative DNA Damage Repair and Protects Against Acute Liver Failure by Acetaminophen

Advanced Science, EarlyView.
Chemical switching of OGG1 by CMM‐98 accelerates oxidative DNA damage repair and enhances hepatocyte resilience during acetaminophen‐induced acute liver injury. By promoting efficient processing of OGG1‐generated repair intermediates, CMM‐98 reduces oxidative damage, preserves cellular integrity, and protects against acute liver failure, identifying ...

Self‐Healing Pd(II) Cage Metallogels for Iodine Capture in Water and Heterogeneous Photocatalysis

Advanced Science, EarlyView.
Two carbazole‐derived metal‐organic cages hierarchically self‐assemble into supramolecular metallogels that integrate autonomous self‐healing, reversible stimuli responsiveness, high‐capacity aqueous iodine capture, and visible‐light‐driven photocatalytic sulfide oxidation within a single multifunctional platform.
