Evading Strength–Ductility Trade‐Off in Titanium Matrix Composites via High‐Critical Resolved Shear Stress Dislocation Promotion and Grain Subdivision

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The strength and ductility trade‐off in titanium matrix composites (TMCs) is a critical factor limiting their widespread application. In this study, a (TiB + TiC)/Ti–6Al–4V composite with an optimal balance between strength and ductility was engineered via multi‐directional forging.

Metal‐Doped Carbon‐Based Nanomaterials: Photothermal Mechanism Innovation and Precision Therapy Advancement in Antibacterial and Antitumor Applications

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Metal‐doped carbon‐based nanomaterials (M‐CNM) play a strategically significant role in next‐generation precision antibacterial and antitumor therapies, as they integrate synergistic photothermal ablation, catalytic reactive oxygen species (ROS) generation, and multimodal imaging capabilities. However, their clinical translation is hindered by

Achieving Superior Strength‐Ductility Synergy in Bionic Magnesium‐Iron Composites by Topological Optimization

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Magnesium (Mg)‐based composites are regarded as promising lightweight materials with significant potential for structural applications. The structure–property relationships of bionic Mg‐based composites remain unclear. Herein, three honeycomb‐like Mg‐Fe composites are fabricated to uncover the underlying strengthening mechanisms.

Sustainable Nanocellulose‐Based Materials for Environmental Remediation: Structure–Function Relationships and Applications

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Environmental pollution across water, air, and soil systems poses escalating threats to human health and ecosystem stability, driven by heavy metals, persistent organic pollutants, particulate matter (PM), bioaerosols, and toxic gases. Conventional remediation technologies often suffer from limited selectivity, insufficient efficiency, and the

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.

open access: yesNew Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

野生动物笼舍环境中大肠埃希氏菌对抗生素和消毒剂的抗性分析

open access: yes野生动物学报, 2023
为评价圈养野生动物笼舍环境中细菌对抗生素和消毒剂的抗性,从大象馆、猛兽馆、鸣禽馆和猿猴馆舍中分离40株大肠埃希氏菌(Escherichia coli)作为指示菌,检测分离菌株对7种抗生素的敏感性和4种消毒剂的最低抑菌浓度(MIC),并对携带的抗性基因进行筛选。结果显示:分离株对复方新诺明和氨苄西林的耐药率较高,分别为50.0%和40.0%,其次为头孢噻肟7.5%,诺氟沙星和庆大霉素耐药率均为5.0%,对美罗培南敏感,主要耐药谱型为氨苄西林加复方新诺明。分离菌株对过氧乙酸消毒剂较敏感,MIC值≤1∶1 ...

Colorimetric and Photothermal Hollow Nanocomposite Based on Silver‐Seeded Prussian Blue Analog for Dopamine Monitoring and Photothermal Sterilization

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Multi‐element Prussian blue analog (PBA) nanocomposites have attracted wide attention for their superior characteristics to single‐functional nanomaterials in extensive applications of diagnosis and therapy. In this study, a novel hollow nanocomposite was designed and fabricated by embedding S2− and Ag nanoparticles into a NiCuMnFe (PBA).

The Microstructure Evolution and Mechanical Properties of (FeCoCrNi)100‐x(AlCu)x High‐Entropy Alloys

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT This study systematically investigates the effects of AlCu addition on the microstructural evolution and mechanical properties of (FeCoCrNi)100‐x(AlCu)x (x = 0, 5, 10, 15, 20; at%) high‐entropy alloys (HEAs). The results reveal that the microstructure evolves from coarse equiaxed to refined equiaxed, dendritic, and ultimately dual‐phase ...
