Alternative perimetric tests for patients with drug-resistant epilepsy.

PLoS ONE
ObjectiveVisual field assessment is an important presurgical test for patients with drug-resistant epilepsy (DRE), particularly with posterior cortex epilepsy. However, the assessment using conventional perimeters like Humphrey Visual Field Analyzer (HFA)

Matrix Stiffness Governs Fibroblasts’ Regulation of Gingival Immune Homeostasis

Advanced Materials, EarlyView.
This study identifies a “mechano‐epigenetic” checkpoint in which matrix stiffness governs the immune responses of gingival fibroblasts. Using biomimetic hydrogels and human gingival explants, the studies revealed that restoring extracellular matrix stiffness actively suppresses inflammation via non‐canonical NF‐κB signaling and DNA methylation ...

Recent Progress on Flexible Multimodal Sensors: Decoupling Strategies, Fabrication and Applications

Advanced Materials, EarlyView.
In this review, we establish a tripartite decoupling framework for flexible multimodal sensors, which elucidates the underlying principles of signal crosstalk and their solutions through material design, structural engineering, and AI algorithms. We also demonstrate its potential applications across environmental monitoring, health monitoring, human ...

Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

Advanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Investigating the Structural Factors Influencing the Magnetic Interaction between Individual Copper Spins in the CuCu4 Metallacrown Complex, from Its Bulk Form to Its Adsorption on Au(111)

Advanced Materials Interfaces, EarlyView.
The Cu(II)[12‐MCCu(II)N(Shi)‐4] metallacrown complex (CuCu4) is studied to examine how geometric transformations affect magnetic coupling between copper spins by using ultraviolet photoemission spectroscopy and DFT calculations for the bulk phase and CuCu4 adsorbed on Au(111). While adsorption minimally affects tDOS, exchange coupling constants between

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications

Advanced Materials Technologies, EarlyView.
A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.

Perfusion Bioreactor Culture Incorporating Mechanical Confinement Enhances Mesenchymal Stem Cell Extracellular Vesicle Production and Wound Healing Potential

Advanced Materials Technologies, EarlyView.
Scalable manufacturing challenges and limited potency remain two of the most intransigent issues limiting clinical translation of EV therapeutics. Mechanical cues can induce phenotypic changes and increased vesiculation in EV source cells without the use of extraneous reagents, chemicals, and/or cargo, thereby potentially drastically improving the ...
