Orthogonal Passivation of Polar Facets for Efficient InSb Quantum Dot SWIR Photodetectors

open access: yesAdvanced Materials, EarlyView.
An orthogonal passivation strategy is developed for indium antimonide (InSb) colloidal quantum dots (CQDs): a metal halide passivates Sb‐terminated surface sites, while thiol ligands passivate In‐terminated sites. This site‐specific passivation reduces trap density, prolonging carrier lifetime and increasing carrier mobility, and enables InSb CQD ...

A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

open access: yesAdvanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

Anchored Fluoro‐Shielded Solvation for Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
Anchored fluoro‐shielded solvation reconstructs PVDF‐based polymer electrolytes by coupling polyanionic Li+‐solvate sites with fluorinated shielding segments. This design organizes anion‐rich solvation networks, strengthens selective Li+ transport, and generates LiF‐rich solid electrolyte interphase, enabling high conductivity, wide oxidative tolerance,

A Noninvasive Approach to Study Localized Forces in 3D Epithelia

open access: yesAdvanced Materials, EarlyView.
Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

Life‐Like Ferrous Oxide Microspheres from Kombucha

open access: yesAdvanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.
