Synchronized Imaging of Hydrogen Peroxide and Hydroxyl Radical in Pyroptosis and Epilepsy

Advanced Science, EarlyView.
A dual‐responsive fluorescent probe, HH, enables synchronized visualization of H2O2 and •OH through spectrally resolved green and red channels. By tracking redox dynamics in pyroptosis and epilepsy models, HH reveals ROS elevation during seizure‐like pathology and supports evaluation of antioxidant and antiepileptic therapeutic interventions.

Beyond Canonical CO Oxidation: Structural and Evolutionary Insights Into a Non‐Canonical Carbon Monoxide Dehydrogenase

Angewandte Chemie, EarlyView.
Clade B carbon monoxide dehydrogenases (CODHs) remain enigmatic, diverging from canonical CODHs in structure and function. Here, we present the first characterization of Ruminococcus flavefaciens CODH (RfCODH), revealing occluded substrate pathways and attenuated CO oxidation activity.

Battery‐Inspired Electrochemical Synapses for Neuromorphic Applications

Advanced Science, EarlyView.
Battery‐ion‐inspired synaptic devices integrate diverse electrolyte systems (solid, ion‐gel, liquid) with transition metal oxides, two‐dimensional materials, and organic channels to regulate ion‐electron coupling. By tailoring ion transport and host interactions, these platforms enable controllable plasticity and energy‐efficient implementations for ...

Light‐Enhanced Chloride Transport by Thiourea‐Appended Molecular Motor

Angewandte Chemie, EarlyView.
A molecular motor functionalized with a thiourea anion‐binding motif mediates transmembrane chloride transport. Light irradiation enhances transport efficiency by populating a more active metastable isomer, which slowly equilibrates to the initial stable isomer.
