C-Band Translation by Second-Harmonic Generation in an Orientation-Patterned Gallium Phosphide Waveguide

International audienceOrientation-patterned gallium phosphide (OP-GaP) is studied for frequency combs conversion from C-band to visible. Simulations of periodic and chirped OP-GaP waveguides nonlinear response are presented.

GaSex Nanoparticles Modulate Neutrophil Function and Mitigate NET‐Driven Osteogenic Impairment in Osteomyelitis Therapy

Advanced Materials, EarlyView.
Neutrophil extracellular traps (NETs) emerge as a critical repair‐limiting factor in osteomyelitis, driving osteoblast mitochondrial dysfunction and excessive PINK1/Parkin‐mediated mitophagy. Gallium–selenium nanoparticles (GaSex) scavenge reactive oxygen species, redirect neutrophils from NETosis toward bactericidal phagocytosis, eliminate methicillin‐

Quantification of Magnetic Interactions in van der Waals Heterostructures Using Lorentz Transmission Electron Microscopy and Off‐Axis Electron Holography

Advanced Materials, EarlyView.
Cross‐sectional Lorentz TEM and off‐axis electron holography visualize the magnetic domain structure and quantify interlayer coupling in Fe3GeTe2/graphite/Fe3GeTe2 heterostructures. A stray‐field coupling length of 37±$\pm$7 nm marks the onset of domain misalignment between the layers.

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 ...

A Family of Sodium Solid‐State Electrolytes Based on the NaGaxAl1‐xCl4 Solid Solution

Advanced Materials Interfaces, EarlyView.
ABSTRACT Sodium‐based metal chloride solid electrolytes are promising for sodium solid‐state batteries due to their excellent oxidation stability, which, as shown for Li halides, can coexist with high ionic conductivity. To explore cationic substitution effects, we synthesized NaGaxAl1‐xCl4 (0 ≤ x ≤ 1) via ball milling and investigated structural and ...
