Inverse Thermal Softening Behavior in a High‐Entropy Alloy Under Various Strain Rates

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Although face‐centered cubic high‐entropy alloys (HEAs) have received extensive attention and in‐depth research, most existing studies focus on single temperature or strain rate conditions, lacking systematic investigations into deformation mechanisms under extreme thermomechanical coupling environments.

Lattice‐Defect‐Coordinated Microstructural Continuity and Mechanical Compatibility in LPBF‐Fabricated CoCrNi/316L Bimetallic Structures

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Bimetallic structures fabricated by laser powder bed fusion (LPBF) provide an effective strategy for achieving multifunctional integration, yet interfacial structural continuity and the role of lattice defects remain insufficiently understood.

A Comprehensive Reassessment of the Global Illegal Wildlife Trade's Economic Value 全球非法野生动植物贸易经济价值的全面重新评估

open access: yesIntegrative Conservation, Volume 5, Issue 3, Page 293-305, September 2026.
Through systematic price collection and correction for underreporting and undetected seizures, the global illegal wildlife trade (IWT) is estimated at US$28.4–39.5 billion per year. This finding highlights that previous valuations were underestimates.

Constructing Integrative Catalytic Pairs in Carbon Nanohorns for Enhanced Neutral H2O2 Electrosynthesis

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Electrosynthesis of hydrogen peroxide (H2O2) via the two‐electron oxygen reduction reaction (2e−ORR) offers a sustainable and decentralized alternative to the anthraquinone process. However, conventional solo‐active‐site catalysts are intrinsically limited by scaling relationships, imposing a trade‐off between activity and selectivity.

Time‐Efficient Columnar‐to‐Equiaxed Transition via High Magnetic Field Processing

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The need to simplify processing routes and improve processing efficiency motivates the development of time‐efficient methods for inducing the columnar‐to‐equiaxed transition (CET) during solidification while tailoring material performance. Conventional multistep CET approaches are time‐consuming and often struggle to simultaneously regulate ...

Hybrid Flexible–Soft Neural Interface as a Practical Solution for Long‐Term Implants

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Implantable neural interfaces face persistent challenges in long‐term functionality due to chronic immune responses, mechanical mismatch with tissue, and material corrosion in vivo. The commonly used flexible materials, such as polyimide and parylene‐C (poly[monochloro‐p‐xylylene]), have advantages in low water vapor permeability and high ...

Fetuses exposed to an episode of threatened preterm labor delivered at or near term show signs of cardiac remodeling

open access: yesUltrasound in Obstetrics &Gynecology, Volume 68, Issue 3, Page 395-405, September 2026.
ABSTRACT Objective To evaluate whether fetuses exposed to threatened preterm labor (PTL) without intra‐amniotic infection or inflammation (IAI), who were born ≥ 34 weeks' gestation, show signs of cardiac remodeling and dysfunction at admission and 4 weeks after the episode of threatened PTL.

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...
