Visible‐Light Photocatalyzed Selective Synthesis of 1,2‐ or 1,3‐Dithianes From Thietanes: An Experimental and Theoretical Study

Advanced Synthesis &Catalysis, EarlyView.
Although this article formally presents a regioselective photochemical ring enlargement of thietanes into 1,2‐ or 1,3‐dithianes, time‐dependent density functional theory calculations have revealed that 1,3‐dithianes are in fact formed thought photoinduced hydrogen atom transfers from 1,2‐dithianes initially resulting from the ring enlargement using ...

Photoelectrochemical Hydrogen Production Using TiO2/Mn‐CdS Photoanode with ZnS Passivation and CoPi as Hole Transfer Relay

Advanced Sustainable Systems, EarlyView.
The electrode features TiO2 as a stable UV‐absorbing substrate, Mn‐doped CdS to extend light absorption into the visible range, ZnS to prevent CdS photocorrosion, and an outer cobalt phosphate (CoPi) that catalyzes oxygen evolution, efficiently enhancing hole transfer from the photoanode to the electrolyte.

Navigating Transition Metal‐Dependent Cell Death: Mechanisms, Crosstalk, and Future Directions

Advanced Science, EarlyView.
Transition metals trigger distinct regulated cell death pathways beyond traditional apoptosis. This review examines ferroptosis (iron‐catalyzed lipid peroxidation) and cuproptosis (copper‐induced mitochondrial proteotoxicity), while exploring hypothetical “cobaltosis” as a novel pathway.

Cell Viability, Drug Screening, and Mechanism Study Under Mild Phototherapy Integrated Chemotherapy (PIC)

Advanced Science, EarlyView.
Mild phototherapy integrated chemotherapy (mild‐PIC) monitored by real‐time impedance spectroscopy enhances drug efficacy in liver cancer via the “More Light‐Aiding, Less Bonding (LALB)” mechanism, achieving higher targeting with lower toxicity. Abstract Phototherapy integrated chemotherapy (PIC) offers a promising cancer treatment strategy as single ...

Stimuli‐Responsive CuFeTe2 Nanosheets for Amplified Cuproptosis/Ferroptosis in Triple‐Negative Breast Cancer Therapy

Advanced Science, EarlyView.
Dual‐stimuli‐responsive CuFeTe2 nanosheets (CFT) induce cuproptosis/ferroptosis via TME‐responsive Fe2⁺/Cu2⁺ release and NIR‐II photothermal effects, amplifying ROS and depleting HSP70/ATP to trigger ICD and immune activation, while ensuring biocompatible renal clearance for TNBC therapy.
