Programmable Microgel Degradation in Dynamic Granular Hydrogels Guides Extracellular Matrix Assembly During Tissue Repair

Advanced Materials, EarlyView.
This study reports on the chemical modification of hyaluronic acid to create hydrogels with hydrolytic degradability ranging from 2–28 days. Granular hydrogels that undergo timed degradation to increase porosity enhance cell invasion and provisional ECM remodeling in a muscle injury model, leading to reduced fibrosis and improved regeneration ...

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

Advanced 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.

Highly Efficient Functionalization of hBN With Lithium Oxalate: A Multifunctional Platform for Composites, Ion Transport, and Spin Labeling

Advanced Materials, EarlyView.
Mechanochemical functionalization of hexagonal boron nitride with lithium oxalate produces LBNCO (Li2(BN)6C2O4${\mathrm{Li}}_{2}{\operatorname{(}\mathrm{BN})}_{6}{\mathrm{C}}_{2}{\mathrm{O}}_{4}$), a layered, intrinsically lithiated material that combines Li+${\rm Li}^+$ transport with high thermal stability and persistent paramagnetic centers.

A Noninvasive Approach to Study Localized Forces in 3D Epithelia

Advanced 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.

Ferroionic‐Assisted, Charge‐Driven Polymorphic Phase Engineering for Multilevel Memristive Devices

Advanced Materials, EarlyView.
A CuInP2S6/Mo0.92W0.08Te2 heterostructure enables a gradual semiconductor‐to‐semimetal phase transition through Cu+ ion migration and charge accumulation. The spatially engineered 2H/1T′ mixed phases produce continuously tunable conductance states in a two‐terminal geometry, while suppressing depolarizing fields and stabilizing the metastable 1T′ phase.

High Energy Photon Induced Defect Engineering in Ultra‐Thin Indium Oxide Transistors for BEOL‐Compatible Logic Circuits

Advanced Materials Interfaces, EarlyView.
Xenon flash lamp annealing modulates oxygen‐vacancy states in 1‐nm‐thick ALD In2O3 transistors within a single 139 µs pulse. The photon‐induced defect engineering shifts the threshold voltage, improves bias‐stress stability, and narrows device‐to‐device variation across 64 devices. Combining pristine and treated transistors yields NMOS inverters with a

Mechanical Mapping of Thin Elastic Films and Living Cells With Spherical Tip Atomic Force Microscopy Probes at Large Indentations

Advanced Materials Interfaces, EarlyView.
A new explicit semi‐analytical model for elasticity determination by AFM is presented using spherical probes. The model, validated with numerical simulations, is applied to the study of polyacrylamide hydrogel films and macrophage cells, showing excellent agreement with the experimental data. It is foreseen its wide applicability to obtain quantitative

Hybrid Roll‐To‐Plate Printed CMOS Logic Circuits Via an Integrated Gravure‐Flexographic Printing Strategy

Advanced Materials Interfaces, EarlyView.
A layer‐specific hybrid gravure–flexographic printing strategy enables fully printed SWCNT thin‐film transistors and CMOS logic circuits on flexible substrates. Flexographic printing forms the thin gate and drain‐source electrodes with defined edges, whereas gravure printing forms the uniform dielectric, semiconductor, and doping layers. The integrated
