A Metalloporphyrin Nanosystem Enables Non‐Invasive Visualization and Specific Treatment for Thrombosis and Ischemic Stroke

open access: yesAdvanced Science, EarlyView.
Thrombotic ischemic stroke is a severe neurological disease of the brain that presents major challenges for effective diagnosis and treatment. Precisely engineered Ir and Mn cores within a single porphyrin framework of 4IrMn nanoparticles enable endogenous ONOO−‐ or laser‐activated switching among NIR‐CL imaging, photothermal / photodynamic therapy ...

Transition‐Metal‐Free Zeolite Composites for Tandem Catalytic Conversion of Methane to Light Olefins

open access: yesAdvanced Science, EarlyView.
Light olefins can be produced from methane using a cascade catalytic system that combines transition‐metal‐free (FER zeolite with an acidic zeolite, such as SAPO‐34, under relatively mild conditions. In this tandem process, methane is first oxidized to methanol over the FER zeolite and then converted to olefins via the MTO reaction on the acidic ...

Defect‐Engineered Bulk Conversion Anodes for Fast and Temperature‐Adaptive Na+ Storage

open access: yesAdvanced Science, EarlyView.
Defect‐engineering has been rationally applied in bulk conversion anodes for sodium ion batteries. The typical carbon‐free/defect‐rich bulk‐Fe7Se8‐x realizes extraordinary fast and temperature‐adaptive sodium ion storage. Various in/ex situ experimental characterizations and DFT calculations verify the peculiar conversion‐type reaction mechanism and ...

Pre‐Constructed Mechano‐Electrochemical Adaptive Solid Electrolyte Interphase to Enhance Li+ Diffusion Kinetics and Interface Stability for Chemically Prelithiated SiO Anodes

open access: yesAdvanced Science, EarlyView.
Silicon oxide (SiO) is emerging as the most advanced anode material. Herein, we propose a chemical prelithiation‐mediated strategy for SiO, which improves initial Coulombic efficiency (ICE) and pre‐constructs a mechano‐electrochemical adaptive solid electrolyte interphase (SEI). Notably, the mechano‐electrochemical adaptive SEI enriched with LiF, Li3N,
