Visualizing and Quantifying Impact with Mechanochromic Sensing Paints Based on Self‐Assembled Polydiacetylene‐Silk Core‐Shell Vesicles

Advanced Science, EarlyView.
Tracking physical impacts is important in many fields. Self‐assembled microparticles made from polydiacetylene and silk fibroin that change color from blue to red when hit can provide an alternative approach to traditional mechanical transducers, quantitatively visualizing impact with responses ranging from <100 to 770 N.

A Van der Waals Material Exhibiting Room Temperature Broken Inversion Symmetry with Ferroelectricity

Advanced Science, EarlyView.
This study reports a βp$\ubeta^{\text{p}}$ phase of indium selenide showing ferroelectricity over large areas at room temperature in a low‐dimensional limit. It is found that indium selenide films with βp$\ubeta^{\text{p}}$ layers display electric field‐induced switchable polarization characteristic of ferroelectric materials, suggesting the breaking ...

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Giant Isotope Effect in Metal–Organic Frameworks Boosts Unprecedented Photo‐ and Radio‐Luminescence Enhancement

Advanced Science, EarlyView.
Deuterated MOFs in this work exhibited unprecedented giant luminescence isotope effect via O─H oscillator suppression, achieving maximal solid‐state materials emission enhancement. This yields significantly improved X‐ray detection sensitivity and imaging resolution, marking the first integration of MOFs with isotopic luminescence and opening new ...
