High‐Throughput Mechanical Rupture of Nuclear Envelope and the Intracellular Dynamics of Massive Wound Repair

open access: yesAdvanced Science, EarlyView.
A microfluidic device with monolithically integrated nanostructures enables high‐throughput wounding of the cell membrane and nuclear envelope. The spatial distribution of charged multivesicular body protein 4B (CHMP4B) within the cell is mapped before and after wounding, showing involvement in repair of both the cell membrane and nuclear envelope ...

Relaxor Ferroelectricity Enables Enhanced Thermoelectric Performance in In2Se3‐Alloyed GeTe

open access: yesAdvanced Science, EarlyView.
A non‐equimolar In3+/Se2− alloying strategy creates Ge vacancies in GeTe, inducing relaxor ferroelectricity that broadens the low thermal conductivity window. Simultaneously, cubic phase stabilization broadens optimal electrical transport, achieving an average zT > 1.0 over 330–625 K.

Programming Structural Symmetry and Emission in Low‐Dimensional Hybrid Perovskites via Time and Temperature

open access: yesAdvanced Science, EarlyView.
We demonstrate programmable structural symmetry and emission in benzylammonium‐based low‐dimensional hybrid perovskites. Continuous shaking transforms orthorhombic platelets into a lower‐symmetry monoclinic phase with broadband emission, whereas thermal activation drives the reverse pathways toward a higher‐symmetry configuration resembling the ...

Gas Sensing With Aerogels: A Critical Review on Structure‐Property Correlations and Performance Optimization

open access: yesAdvanced Science, EarlyView.
With high specific surface area, and adjustable interface, aerogel provides a multi‐functional platform for gas sensing. This review systematically links structural parameters (specific surface area, pore size, heterojunctions) to sensing metrics (sensitivity, selectivity, stability), critically evaluates optimization strategies, and outlines future ...

Heat Stress Promotes Fibroblast‐Derived WNT5A Secretion Through m6A Modification to Activate Melanogenesis

open access: yesAdvanced Science, EarlyView.
Heat stress promotes WNT5A secretion from fibroblasts via METTL3/YTHDC1‐dependent m6A methylation. Subsequently, WNT5A binds to FZD10 on melanocytes, activating β‐catenin‐driven melanogenesis. ABSTRACT As the impact of global warming continues to intensify, the effects of heat stress on the skin are becoming increasingly evident.

Soft Hypoxia‐Adaptive Bioelectronics Integrating PEDOT:PSS/Polydopamine/Enzyme Biocomposites for Closed‐Loop Therapeutics of Chronic Wounds

open access: yesAdvanced Science, EarlyView.
Hypoxia‐adaptive bioelectronics based on poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)/polydopamine (PDA)/enzyme biocomposites couple O2‐centric biosensing with embedded O2 therapy to address oxygen‐deficient chronic wounds. Local O2 provision restores enzyme‐based metabolite sensing, while catalase‐mediated oxygen generation and

Nanoparticle‐Mediated Bubble Suppression During Droplet Solidification for Mechanical Reinforcement

open access: yesAdvanced Science, EarlyView.
Nanoparticles mediate droplet solidification by raising nucleation temperature, refining dendrites, and slowing freezing‐front advance, thereby suppressing trapped air bubbles in droplet‐based 3D printing. This strategy reduces bubble volume fraction by ∼35% and increases compressive strength by up to 39%, offering a low‐cost route to stronger printed ...

Differential Tissue‐Coupled Powering for Battery‐Free Injectable Electroceuticals

open access: yesAdvanced Science, EarlyView.
A thread‐like injectable neural stimulator is powered through differential tissue‐coupled powering (DTCP), which harvests RF‐frequency tissue potentials with an elongated receiver while preserving a injectable cross‐section. The system integrates an ASIC, stimulation electrodes, and a portable transmitter, enabling wireless peripheral nerve stimulation,
