Stepwise warm rolling for synergistic strength and ductility enhancement in heterolamellar medium-Mn steel

Journal of Materials Research and Technology
Medium manganese steel represents a promising third-generation advanced high-strength steel. However, achieving excellent plasticity in high-yield-strength medium manganese steel remains challenging, particularly with lower alloying element contents.

Chronic Disease and Disability in the United States: Trends, Inequities, and Imperatives for Policy Reform

The Milbank Quarterly, EarlyView.
Policy Points Position Universal, High‐Quality Education as a Foundational Public Health Strategy. Long‐term health and life expectancy in the United States are shaped more by educational attainment than by any other single factor. Disparities in access to early childhood, K‐12, and higher education perpetuate cycles of chronic disease, economic ...

Edges as ecological filters: Asymmetrical orientation‐specific arthropod activity across forest boundaries

Insect Science, EarlyView.
Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Microstructure and mechanical properties of extruded Mg-Sn alloys with a heterogeneous grain structure

Journal of Magnesium and Alloys
The high-strength Mg-7Sn alloys (wt.%) with a heterogeneous grain structure were prepared by low-temperature extrusion (230 °C) with the extrusion ratio of 9:1 (9E230) and 17:1 (17E230).

Disparities in delegation size and their implications for equitable participation at CITES CoP meetings

Conservation Science and Practice, EarlyView.
We analyzed delegation size, voting records, and working‐group rosters across five CITES Conferences of the Parties (CoP16–20) to examine how Party‐level traits predict delegation size and how delegation size shapes participation when Committees meet concurrently.

Superior tensile properties induced by triple-level heterogeneous structures in the CoNiV-based medium-entropy alloy [PDF]

The strength-ductility trade-off was evaded by deploying a triple-level heterogeneous structure into a CoNiV-based medium-entropy alloy (THS MEA). The innovative hetero-structures comprise chemical short-range ordering (CSRO) at the atomic level, B2 ...

High strength and ductility in a dual-phase hetero-structured AlCoCrFeNi2.1 eutectic high-entropy alloy by powder metallurgy

Materials Research Letters
We used powder hot extrusion followed by annealing to fabricate a dual-phase AlCoCrFeNi2.1 eutectic high-entropy alloy consisting of both non-recrystallized and recrystallized grains with dense nano-sized precipitates arranged in heterogeneous structures.

Gender Justice in the Triple Planetary Crisis: A Scoping Review

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aim To identify and report how gender justice is conceptualised and discussed in contemporary health literature in relation to the Triple Planetary Crisis of climate change, pollution and biodiversity loss, with a particular focus on the experiences of women and gender‐diverse populations, and the representation of nurses and other healthcare ...

Photocatalytic Lignin Depolymerization and Cross‐Coupling With Alcohols to Produce Unsymmetric Aromatic Diols

Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.
A photocatalytic approach for efficient one‐pot direct lignin depolymerization and subsequent cross‐coupling with alcohols for the production of unsymmetrical aromatic diols has been demonstrated. ABSTRACT Conversion of lignin into chemical products typically involves two separate steps, such as depolymerization and subsequent upgrading of monomers ...

Enhanced strength and ductility in (CoCrNi)92Mo2Al6 medium entropy alloy via dual heterogeneous structures

Materials Research Letters
In the present (CoCrNi)92Mo2Al6 medium entropy alloy (MEA), a dual heterogeneous structure is achieved by regulating the degree of recrystallization of the FCC matrix and σ phase precipitation through incomplete annealing.
