Manipulating Surface Chemistry on the Microarchitecture of Coal‐Based Hard Carbon for Improved Sodium Storage

open access: yesAdvanced Science, EarlyView.
This study utilizes surface chemistry engineering to enhance coal‐based carbon materials for sodium storage. By introducing oxygen‐containing functional groups (OFGs) via pre‐oxidation, the researchers found that carboxyl groups delay decarboxylation during pyrolysis, enabling extended intermolecular rearrangement up to 600 °C while suppressing soft ...

Coupling of Engineered High Entropy Alloys with Semiconducting TiO2 Nanofilms for Scalable and Ultrafast Alkaline Hydrogen Evolution Reaction

open access: yesAdvanced Science, EarlyView.
A facile and scalable strategy is presented to fabricate high‐performance hybrid photoelectrocatalysts combining PtFeCoNiCu HEA and TiO2–NFs via sequential anodization and electrodeposition, achieving an ultralow overpotential of –11 mV at η10 and excellent thermal stability. Abstract High entropy alloys (HEAs) are a promising class of electrocatalysts

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 ...

Long‐Term Stable Subdural Recordings Enabled by Fibrosis‐Resistant Hydrogel‐Integrated µECoG Arrays

open access: yesAdvanced Science, EarlyView.
An adhesive hydrogel‐integrated micro‐electrocorticography (aGel‐µECoG) array is developed to ensure stable neural recordings by minimizing neuroinflammation and fibrosis during implantation. The hydrogel serves as a biological and mechanical bridge, enabling bioadhesive, reversible, anti‐fibrotic integration with brain tissue.
