Exceptional Electromagnetic Wave Absorption in High‐Entropy Carbides Enabled by Lattice Distortion Engineering

Rare Metals, EarlyView.
ABSTRACT The growing concern over human health issues, driven by increasingly severe electromagnetic pollution from 5G communication, has made the urgent development of high‐performance electromagnetic wave (EMW) absorbing materials. Although carbide‐based materials are promising because of their conductive and polarization losses, existing single ...

Phase Hologram by Acoustic Metasurfaces

Small Structures, EarlyView.
This work has achieved a breakthrough in holographic communication, realizing phase holographic imaging. The proposed phase holographic concept overcomes the limitations of traditional amplitude holographic energy attenuation. The design of its amplitude compensation method further addresses the key challenge of phase holographic imaging clarity ...

Revisiting PSF models: Unifying framework and high‐performance implementation

Journal of Microscopy, EarlyView.
Abstract Localisation microscopy often relies on detailed models of point‐spread functions. For applications such as deconvolution or PSF engineering, accurate models for light propagation in imaging systems with a high numerical aperture are required. Different models have been proposed based on 2D Fourier transforms or 1D Bessel integrals.

Modeling and Improving Geometric Accuracy in Projection Multiphoton Lithography

Advanced Optical Materials, Volume 14, Issue 6, 9 February 2026.
A numerical framework describing the optical and photochemical processes is developed to elucidate the origins of geometric deviations in projection multiphoton lithography. The results indicate that oxygen diffusion and inhibition, and DMD diffraction, lead to geometric distortions.

Structure–Reactivity Relationships of Oxime–Oxalate/Glyoxylate/Ester Derivatives: Dual Photo/Thermal Initiators for Visible Light Polymerization and Composite Preparation

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
OP1, a newly synthesized nitro‐carbazole oxime oxalate, shows superior Type I photoinitiation under blue LEDs and sunlight due to efficient decarboxylation. It enables high‐resolution 3D printing, offers dual photo/thermal initiation, lower cytotoxicity than TPO, and provides insights for designing sustainable photoinitiators.

Explicit Compression Degradation Estimations for Low‐Sampling Single‐Pixel Imaging using Hadamard Basis

Advanced Science, Volume 13, Issue 9, 13 February 2026.
This study proposes a degradation estimation technique to explicitly describe compressive sampling for low‐sampling Hadamard single‐pixel imaging. Blur kernels in explicit degradation models are estimated by the self‐supervised learning method without labeled data and implicit priors.

Local‐to‐Nonlocal Second‐Harmonic Generation from Electrically Tunable Intersubband Polaritonic Metasurfaces

Advanced Science, Volume 13, Issue 9, 13 February 2026.
A local‐to‐nonlocal SHG process is demonstrated on an electrically tunable metasurface, combining an LSPR at the FF with a TM‐GMR at the SH to achieve independent dual tunability. Through modal‐overlap engineering of the proposed scheme, a high‐χ(2) MQW meta‐atom delivers strong nonlinearity while achieving 2‐DoF SH control with minimal trade‐offs ...
