Targeted Expansion of Treg Cells to Induce Immune Tolerance after Kidney Transplantation

open access: yesAdvanced Science, EarlyView.
A dual‐targeting nanoparticle platform that selectively engages graft stromal cells via CD248 receptors while employing kidney‐ specific promoters (NPHS2) to drive localized IL‐ 2/TGF‐βexpression is developed. This approach achieves three therapeutic objectives:1) intragraft Treg polarization without systemic cytokine exposure;2) reduced dependence on ...

Ultra‐Thin Oxide‐Based Double‐Layer Architecture Achieves Wide‐Temperature Broadband Microwave Absorption by Synergizing Lorentz Resonance and Thermionic Transport

open access: yesAdvanced Science, EarlyView.
Developing ultrathin wide‐temperature adaptive microwave absorption materials (MAMs) is crucial for enhancing the survival of military devices under alternating high‐temperature environment. Here, a double‐layer La2Zr2O7/Eu2Zr2O7 architecture is employed, with rare‐earth zirconates featuring with one‐eighth anion‐site vacancies, successfully achieving ...

Superelastic High‐Entropy Oxide Ceramic Aerogels for Thermal Superinsulation and Sealing at Extreme Conditions

open access: yesAdvanced Science, EarlyView.
A high‐entropy oxide ceramic of (Gd1/2Lu1/2)2(Ti1/3Zr1/3Hf1/3)2O7 is prepared through a molecular synthesis route of pyrolytic solid‐solution reactions. The architectured nanofiber aerogel manifests unprecedented thermomechanical properties, including superelastic compressibility of 98% from −196 to 1500 °C, and thermal superinsulation capacity (24.14 ...

Piezo‐Phototronic PVDF/HfO2/Nano‐Cu Heterostructured Thin Film for Flexible Self‐Powered Multimodal Sensing

open access: yesAdvanced Science, EarlyView.
Electrospinning a composite of PVDF, HfO2, and nano‐Cu transforms the discrete precursors into a continuous nanofiber mesh, forming a multi‐interface heterostructure with embedded nanoparticles. The presence of HfO2 and nano‐Cu at the fiber interfaces induces a highly aligned β‐phase, which enhances piezoelectric crystallinity and improves the material'

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

open access: yesAdvanced 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 ...
