Freestanding Hierarchical‐Porous BCZT Thin Films Enable Efficient Ultrasonic Energy Harvesting in Soft Tissue

open access: yesAdvanced Science, EarlyView.
Freestanding hierarchical‐porous BCZT thin films integrate a compliant porous surface with a dense piezoceramic backbone to balance mechanical reliability, voltage sensitivity, and acoustic coupling. The films enable stable wearable pulse‐wave monitoring and enhanced tissue‐coupled ultrasonic energy harvesting, offering a promising route toward soft ...

Achieving High‐Instantaneous Pulse Power in Contact‐Separation TENG via Series Capacitive Voltage Control Architecture

open access: yesAdvanced Science, EarlyView.
Conventional contact‐separation triboelectric nanogenerators generate high voltage but deliver limited power due to premature charge dissipation. Here, a capacitive charge reservoir architecture decouples charge accumulation from discharge triggering, enabling sequential voltage amplification via floating‐layer capacitive coupling.

Probing the Energy Landscape of α‐Synuclein Amyloid Fibril Formation by Systematic K‐to‐Q Mutagenesis

open access: yesAdvanced Science, EarlyView.
We use lysine‐to‐glutamine mutations to study the effect of electrostatics on the kinetics and thermodynamics of alpha‐synuclein amyloid fibril formation. We find that mutational effects map on their structural context within fibrils and identify residues that modulate the energy landscape of alpha‐synuclein self‐assembly. Our work outlines a scalable,

Single‐Nucleus Atlas of Spinal Sarcopenia Patients Reveals Disruption of Quiescent and Regenerative Satellite Cell Niches in Fatty‐Infiltrated Muscle

open access: yesAdvanced Science, EarlyView.
Mechanisms of Fatty Infiltration and Muscle Degeneration. Clinical metadata identified intramuscular fat accumulation as an independent driver of muscle mass decline. Single‐nucleus RNA sequencing of spinal sarcopenia muscle revealed adipogenic reprogramming of fibro‐adipogenic progenitors, satellite‐cell niche disruption, and elevated levels of the ...

DDX21 Enhances Radiosensitivity in Head and Neck Squamous Cell Carcinoma by Suppressing MK2‐Mediated DNA Damage Response

open access: yesAdvanced Science, EarlyView.
DDX21 suppresses MK2 activation by directly inhibiting Thr334 phosphorylation in a p38‐independent manner, thereby impairing DNA damage response. Clinically, patients with well‐differentiated tumors exhibiting high DDX21 expression are more likely to benefit from adjuvant radiotherapy, whereas those with low DDX21 levels are predisposed to ...

A General High‐Throughput Mucus Microrheology Platform for Quantitative and Scalable Mucus Phenotyping

open access: yesAdvanced Science, EarlyView.
High‐throughput Differential Dynamic Microscopy measures frequency‐resolved mechanical fingerprints from 3 to 10 μL$\umu{\rm L}$ mucus samples using only a few minutes of operator attention per sample. This automated analysis enables scalable mucus phenotyping for translational research by distinguishing mechanical heterogeneity among donors, disease ...

Bioinspired Metastable Transient Peeling for Repeatable Rapid Release

open access: yesAdvanced Science, EarlyView.
Inspired by the explosive seed ejection of the squirting cucumber, this work introduces metastable transient peeling that temporally regulates stored interfacial energy release via a tunable energy barrier. A viscoelastic hemispherical gripper achieves 52 ms ultrafast, residue‐free release with 300 000‐cycle durability, enabling damage‐free handling of
