A Simple Descriptor for Solid‐State Ionic Conductors Across Chemistries

Advanced Materials, EarlyView.
Researchers develop a simple and transferable descriptor, distance contraction, for solid‐state ion migration across Li‐, Na‐, K‐, and Mg‐ion conductors and diverse anion chemistries. By capturing the maximum local contraction experienced by the migrating ion, the descriptor enables rapid materials screening and unifies diverse ion‐transport mechanisms.

Monolithically 3D‐Printed Spectral‐Spatial Meta‐Authenticators

Advanced Materials, EarlyView.
A single height map printed in a low‐index resin by two‐photon lithography encodes multiple visible wavelengths in one metasurface without any polarization optics. A fabrication‐aware optimization folds the printable height levels into the design, so the device is printed as optimized.

Near‐Infrared Imaging of H2O2 in Plants With Nanosensors Under Environmentally Changing Conditions

Advanced Materials, EarlyView.
This paper reports a ratiometric nanosensor enabling robust, multivariate detection of stress signals (H2O2) in plants, with high resistance to light fluctuations and mechanical disturbances. Single‐walled carbon nanotubes serve as the sensor, Egyptian Blue nanosheets serve as a stable reference, and plant autofluorescence serves as a label‐free ...

From Water Vapor Transmission Rate (WVTR) to Intrinsic Water Vapor Permeability (WVP)

Advanced Materials, EarlyView.
Breathable membranes can appear less permeable when the measurement apparatus limits vapor transport. A calibrated four‐step model describes membrane permeation and apparatus effects as resistances in series under a common chemical‐potential driving force.

Surface Functionalization Modulates Collective Cell Behavior Near Topological Defects Induced by Topographical Patterning

Advanced Materials Interfaces, EarlyView.
Strongly adhered cells align with concentric circular ridges and exhibit predominantly tangential motion, whereas weakly adhered cells fail to follow topographical guidance and display enhanced radial inward motion. ABSTRACT Living cells establish long‐range orientational order through collective alignment, giving rise to topological defects whose ...
