In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

open access: yesAdvanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Thermally Induced Creep and Viscoelastic Behavior of Copper Micropillar Arrays

open access: yesAdvanced Science, EarlyView.
Copper micropillar arrays are fabricated by electrodeposition within through‐glass‐via, and their thermally induced time‐dependent deformation is quantified. Nanoindentation creep, EBSD, and TEM reveal a heat‐treatment‐driven transition between grain‐boundary‐mediated deformation and dislocation‐dominated creep, while Kelvin modeling captures ...

Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics

open access: yesAdvanced Science, EarlyView.
Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.

Quantitative Stain Mapping in X‐Ray Virtual Histology

open access: yesAdvanced Science, EarlyView.
Virtual histology promises 3D tissue examination without physical sectioning, yet has lacked the tissue‐specificity of conventional pathology. This work demonstrates the first quantitative three‐dimensional stain mapping at histologically relevant resolution, separating contrast agent from tissue to reveal cellular features such as nuclei. The approach

Ferroelectric‐Polarization‐Driven Structural Engineering of Bi3Nb17O47 Anodes for High‐Performance Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
A transformative ferroelectric‐polarization strategy is employed to overcome the intrinsic limitations of tungsten bronze (TTB)‐type anode materials in metal‐ion batteries, using Bi3Nb17O47 as a model system. By exploiting the non‐centrosymmetric crystal structure and field‐induced ionic displacements, controlled structural engineering with ...
