Cobalt and Yttrium Doping to Activate Dual‐Site Mechanism of Amorphous NiFeOOH for Large‐Current Water Electrooxidation

open access: yesAdvanced Science, EarlyView.
The Co and Y‐doped amorphous NiFeOOH catalyst is synthesized via a novel needle‐array electrodeposition. The co‐doping tunes the adsorption energies at Ni and Fe sites, shifting the OER pathway from the traditional adsorbate evolution mechanism to a dual‐site synergistic mechanism confirmed by in situ ATR‐SEIRAS, thereby enhancing large‐current water ...

Tumor Microenvironment‐Responsive Nanomedicines for Potentiating Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
Strategies for TME‐responsive Nanomaterials to Potentiate Cancer Immunotherapy. Abstract Immunotherapy has emerged as a transformative paradigm in oncology, yet its clinical efficacy remains constrained by the immunosuppressive tumor microenvironment and inadequate spatiotemporal control of existing modalities, resulting in suboptimal patient response ...

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 ...

Novel Phosphazenium Tetrafluoroborate Dopant Enables Efficient and Thermally Stable n‐Doped Organic Semiconductors

open access: yesAdvanced Electronic Materials, EarlyView.
A novel n‐dopant, phosphazenium tetrafluoroborate (P2BF4), is introduced for efficient n‐doping in N2200, P(PzDPP‐CT2) and other organic semiconductors (OSCs). P2BF4‐doped OSC films exhibit exceptional thermal stability, maintaining electrical conductivity after heating at > 150 °C for 24 h. This stability allows organic thermoelectric devices based on
