Boosting Photo‐Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering

Advanced Science, EarlyView.
This study reports Ba(Ti0.85Zr0.15)O3 nanocatalysts with enhanced polarization and oxygen‐vacancy‐rich interfaces for efficient NIR‐II photo‐pyroelectric therapy. Zr doping boosts the pyroelectric coefficient and accelerates polarization switching, while oxygen vacancies improve photothermal conversion and surface reactivity.

Multi‐Organelle Stress‐Induced Paraptosis by a ROS‐Amplifying Nanocatalyst for Enhanced Cancer Immunotherapy

Advanced Science, EarlyView.
The engineered TF‐Fe@LC nanoplatform programs paraptotic death via multipath ROS amplification that disrupts redox homeostasis, provoking mitochondrial dysfunction, autophagic blockade, and ER stress. This caspase‐independent process elicits robust immunogenic cell death, combining with αPD‐L1 to activate systemic CD8+ T‐cell immunity and suppress ...

Unearthing Atomic Dynamics in Nanocatalysts

ACS Applied Materials & Interfaces
Being able to access the rich atomic-scale phenomenology, which occurs during the reactions pathways, is a pressing need toward the pursued knowledge-based design of more efficient nanocatalysts, precisely tailored atom by atom for each reaction. However, to reach this goal of achieving maximum optimization, it is mandatory, first, to address how ...

Inhibiting cGAS‐STING to Preserve Mitochondrial–Nuclear Communication and Stemness in Young Tendon Stem Cells: A Hydrogel Strategy against Age‐Related Tendinopathy

Advanced Science, EarlyView.
A dual‐targeting strategy to rejuvenate aged tendons. A reactive oxygen species (ROS)‐responsive hydrogel co‐delivers a selenium nanozyme (scavenges ROS) and a STING inhibitor to tendon stem cells. This combined action restores mitochondria–nucleus communication, alleviates cellular senescence, and rejuvenates tendon regeneration, offering a novel ...
