Integrin‐Piezo1 Axis Drives ECM Remodeling and Invasion of 3D Breast Epithelium

open access: yesAdvanced Science, EarlyView.
Mechanical stiffening of the extracellular matrix around mature mammary acini induces sequential remodeling phases. An early response disrupts the basement membrane and promotes fibronectin secretion, followed by delayed invasion with matrix reorganization and proliferation.

Engineering Dimensional Configuration of Single‐Atom S‐Cu‐S Sites as Reversible Electron Station for Enhanced Peroxidase‐Mimicking

open access: yesAdvanced Science, EarlyView.
L‐cysteine triggers auto‐assembly of POD‐like 3D biomimetic S‐Cu‐S single‐atom nanozymes on MoS2 (MoCC). MoCC shows 16.3‐fold higher catalytic velocity and 17.9‐fold greater affinity than HRP, enabling efficient •OH generation via enhanced electron inversion and transfer.

Defect‐Rich Porous Cu with Abundant Cu(100) for Acidic CO2 Electroreduction in Membrane Electrode Assembly

open access: yesAdvanced Science, EarlyView.
This study introduces defect‐rich porous Cu nanosheets (pCu NS) with abundant Cu(100) facets for efficient acidic CO2RR to C2+ products. The porous structure creates a localized alkaline microenvironment that hinders HER, defects enhance *CO coverage, and the Cu(100) facet facilitates *CO hydrogenation to *COH, demonstrating the essential role of facet/
