Polymorphic Superparaelectric Engineering Boosting Energy Storage Capacity in BaTiO3‐Based Ceramics

open access: yesAdvanced Science, EarlyView.
Herein, Ca2+ incorporation promotes the coexistence of CaTiO3‐/BaTiO3‐derived paraferroelectric states, stabilizing cubic‐orthorhombic‐tetragonal polymorphic superparaelectric phases. This minimizes polarization energy barriers, facilitating full polarization saturation without compromising efficiency.

Nonreciprocal Charge Transport in an Iron‐Based Superconductor with Broken Inversion Symmetry Engineered by a Hydrogen‐Concentration Gradient

open access: yesAdvanced Science, EarlyView.
Concentration gradients can serve as a universal platform for breaking spatial inversion symmetry. We demonstrate this concept by observing nonreciprocal electrical transport—a sensitive probe of inversion‐symmetry breaking—in the iron‐based superconductor Sm1111 with an engineered hydrogen gradient.

Synergistic Intra‐ and Inter‐Nanozyme Electron Transfer through Interfacial Assembly for Enhanced Multi‐Enzyme Activity

open access: yesAdvanced Science, EarlyView.
A novel Prussian blue‐based composite nanoenzymes (PB C‐NZs)‐MoS2/PB, was designed based on the electron transfer mechanism and transport pathway. The structure uses MoS2 as the substrate, with PB grown on its surface through a surface assembly method.

Ultrasound Activated Piezoelectric Dural Patches to Drive Endogenous Neural Stem Cell–Mediated Repair Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
This study presents a wireless, non‐invasive strategy for neural repair by developing a biodegradable piezoelectric dural patch that, under transcranial ultrasound, generates localized electrical fields to drive endogenous neural stem cells toward neuronal differentiation and functional integration.

Halogen‐Bond Coupled Halogenated‐π‐Conjugation Enables Giant Birefringence in Hydrogen‐Bonded Organic Frameworks

open access: yesAdvanced Science, EarlyView.
The perfect crystal packing achieved via the halogen‐bond (XB) coupled halogenated‐π‐conjugation strategy effectively induces an ultrahigh birefringence (Δn = 0.97), which exhibits promising potential in polarization control and phase modulation.
