Negative Gauge Factor Piezoresistance in Soft Strain and Pressure Sensors: Mechanisms, Materials, and Emerging Applications

open access: yesAdvanced Science, EarlyView.
Negative‐gauge‐factor materials reverse the usual rule of piezoresistive sensing: their resistance falls, rather than rises, under deformation. This review organizes such behavior into four mechanistic classes spanning intrinsic semiconductors, composites, conducting polymers, and engineered architectures.

Dual Suppression of Oxidative Stress and JAK/STAT3 Signaling Attenuates Inflammation‐Driven Corneal Neovascularization

open access: yesAdvanced Science, EarlyView.
Corneal neovascularization is sustained by oxidative stress and inflammatory STAT3 signaling. A macrophage membrane‐cloaked nanozyme, Sta@MSR, combines ruthenium‐mediated ROS scavenging with Stattic‐mediated STAT3 inhibition. Delivered as eye drops, Sta@MSR enhances ocular retention and corneal penetration, reduces inflammatory and angiogenic responses,

SynAtlas: A Safe and Versatile Platform for Rapid Organ‐Scale Tissue Clearing and 3D Atlas Mapping

open access: yesAdvanced Science, EarlyView.
An orthogonal synergy design principle integrates lipid solubilization, protein hydration modulation, and refractive‐index matching within a unified aqueous clearing system. This modular strategy enables rapid, low‐hazard, and broadly compatible tissue clearing while preserving molecular signals, supporting multiscale three‐dimensional imaging across ...

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

open access: yesAdvanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Model‐Based Time‐Modulated Write Algorithm for 1R Analog Memristive Crossbar Arrays

open access: yesAdvanced Electronic Materials, EarlyView.
A novel model‐based time‐modulated write algorithm efficiently programs analog 1R memristive crossbar arrays by varying pulse duration at a fixed voltage. By leveraging a physics‐based compact model and a dynamic gain mechanism, this approach overcomes device nonlinearities and parasitic effects.
