Coral‐Like Yolk–Shell‐Structured CoNi@Void@C Microspheres for Enhanced Microwave Absorption, Photothermal, Anti‐Corrosion, and Radiation Shielding Properties

Rare Metals, EarlyView.
ABSTRACT Considering the multiple challenges faced by stealth coatings in complex service environments, the development of multifunctional integrated microwave absorbing materials (MAMs) that combine efficient electromagnetic (EM) attenuation with environmental tolerance has become an urgent need. In this work, coral‐like CoNi@Void@C microparticle (MP)

Noise reduction of electron holography observations for a thin-foiled Nd-Fe-B specimen using the wavelet hidden Markov model

Applied Microscopy
In this study, we investigate the effectiveness of noise reduction in electron holography, based on the wavelet hidden Markov model (WHMM), which allows the reasonable separation of weak signals from noise.

Analysis of Giant‐Shell CdSe/CdS Quantum Dots via Analytical Ultracentrifugation Combined with Spectrally Resolved Photoluminescence

Small Methods, EarlyView.
Analytical ultracentrifugation (AUC) is a powerful tool for studying the size–property relationships of nanomaterials in their native environment. A methodology based on AUC with in‐line multiwavelength emission detection is developed, enabling the measurement of the size‐resolved emission spectra of giant‐shell CdSe/CdS quantum dots.

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 ...
