SARS‐CoV‐2 infection as cause of in‐utero fetal death: regional multicenter cohort study

open access: yesUltrasound in Obstetrics &Gynecology, Volume 62, Issue 6, Page 867-874, December 2023., 2023
ABSTRACT Objective Placental infection with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) can lead to placental insufficiency and in‐utero fetal death (IUFD). The objective of this study was to confirm and quantify the extent to which fetoplacental infection with SARS‐CoV‐2 is a cause of fetal death.

Diagnostic yield using whole‐genome sequencing and in‐silico panel of 281 genes associated with non‐immune hydrops fetalis in clinical setting

open access: yesUltrasound in Obstetrics &Gynecology, Volume 60, Issue 4, Page 487-493, October 2022., 2022
ABSTRACT Objective To investigate the diagnostic yield of clinical whole‐genome sequencing (WGS) in prenatally diagnosed non‐immune hydrops fetalis (NIHF). Methods This was a retrospective study of 23 fetuses with prenatally diagnosed NIHF, negative for trisomies and copy‐number variants, referred for analysis by WGS with an in‐silico panel of 281 ...

Manipulating RE‐O Bonds Engineered Thermal/Oxygen Transport Characteristics of Monoclinic‐Prime RETaO4 High‐Entropy Ceramics

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Multifunctional thermal protective ceramic thermal/environmental barrier coatings (T/EBCs) are of great significance for applications of various high‐temperature components, and we propose an effective strategy for designing high‐entropy ceramics (HECs) as T/EBCs for SiC ceramic matrix composites (CMCs), where low thermal expansion ...

High‐Entropy Alloys for Photocatalysis: From Cocatalyst Engineering to Multifunctional Active Platforms

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Photocatalysis has emerged as a promising approach for solar energy conversion and environmental remediation. However, its practical implementation is still hindered by limited charge‐separation efficiency, slow surface reaction kinetics, and insufficient catalyst stability.

Unveiling Entropy‐Driven Hard‐Tough Synergy Mechanisms in High‐Entropy Carbonitride Ceramics

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT High‐entropy ceramics manifested promise for extreme environments, yet their phase stability and mechanical synergy mechanisms remain elusive. Herein, entropy‐difference carbonitrides, including (TaTiV)CN, (TaTiVNb)CN, and (TaTiVNbHf)CN, were designed and consolidated via spark plasma sintering.

Synergy Effects of Dual‐Gel‐Assisted Structural Engineering and Bimetallic Doping Regulation Realize Ultrastable High‐Rate Performance of NASICON Cathodes for Sodium‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Na‐superionic‐conductor‐type (NASICON) Na4MnV(PO4)3 (NMVP) is an appealing cathode for sodium‐ion batteries (SIBs), but its application is hindered by Jahn–Teller distortions, sluggish Na+ kinetics and poor conductivity, leading to rapid capacity fade.

Synergy Enhancement of Strength and Ductility of Mg‐Based Composites via In Situ Synthesized High‐Entropy Mg24(Y0.25Dy0.25Ho0.25Er0.25)5

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Mg‐based composites have been considered as promising structural materials for aerospace and automotive applications owing to their high specific strength and stiffness. However, their low room‐temperature ductility and absolute strength have limited their wide application.

Thermite‐Synthesized Fe–Ti–Al–Mg High‐Entropy Intermetallic Compound for Efficient Azo Dye Degradation

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.

Large Cation‐Induced Lattice Distortion in Carbon‐Based High‐Entropy Oxides: Spin‐State Engineering and Broadband Microwave Absorption

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT High‐entropy oxides (HEOs) are promising for microwave absorption but suffer from a trade‐off between impedance matching and attenuation, often requiring high filling ratios (> 50 wt%). Herein, we propose a “lattice‐spin” dual‐regulation strategy by introducing giant‐radius Bi into a single‐phase HEO solid solution.

Atom Probe Tomography‐Based Analysis of Residual Trace Elements in Advanced Metallic Materials

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Residual trace elements inherited from raw materials strongly influence the mechanical and environmental performance of advanced metallic alloys and recycling materials due to preferable boundary/interface segregation and resultant embrittlement effects, yet their parts per million level concentrations pose significant challenges to ...
