Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Introducing solid‐state phase transformations into the design of heterogeneous structures is considered an effective strategy for simultaneously optimizing both microstructure and mechanical properties. This study investigates the thermodynamic and kinetic mechanisms of the γ → α transformation in Ti48Al5Nb2Cr0.6Re0.1C alloy under different ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Thermodynamic prediction‐driven phase‐field kinetic simulation, with experimental verification, is utilized to explore the high‐performance cobalt–nickel based (CoNi‐based) superalloys. The roles of aluminum (Al) in microstructural evolution and precipitation kinetics of ordered L12‐γ′ strengthened Co–Ni–xAl superalloys are revealed. The alloy

“The Benefits Far Outweigh the Challenges”: Examining Practices of Queer Shared Households in Canada
Sexuality, Gender &Policy, Volume 9, Issue 1, February 2026.ABSTRACT This paper focuses on the experiences and practices of LGBTQ+ adults in Canada living in shared housing arrangements. Drawing on qualitative focus group data from eight participants aged 32–67 in three Canadian cities, we identify and discuss three key themes that characterize these arrangements: (a) the material drivers and impacts of shared ...

High nitrogen enrichment buffers plant photosynthesis against herbivory damage
Functional Ecology, Volume 40, Issue 1, Page 229-238, January 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivorous insects and nitrogen deposition are key drivers of ecosystem productivity under global change. However, their combined effects on plant photosynthesis, particularly during insect outbreaks, remain poorly understood in natural ecosystems.

野生动物学报, 2023 野生动物应激水平的非损伤性评估是了解野生动物对景观条件产生生理反应的重要方法。粪便皮质醇代谢产物（faecal cortisol metabolites，FCM）水平被认为是评价动物压力的潜在生物标志物。影响濒危东北马鹿（Cervus elaphus xanthopygus）应激的环境因子可能包括道路、植被、人为干扰和海拔等，因此采用酶联免疫分析法（ELISA）分析内蒙古高格斯台罕乌拉国家级自然保护区东北马鹿种群的粪便皮质醇激素数据，利用多元线性回归模型构建东北马鹿粪便皮质醇激素与环境因子的线性关系 ...

New Phytologist, Volume 249, Issue 2, Page 764-776, January 2026.Summary Fine roots are critical for soil resource uptake, yet how declining plant diversity alters fine root biomass (RB) and traits remains unclear. We tested how plant functional trait dissimilarity in shade tolerance, drought tolerance, growth rate, and nitrogen‐fixation ability drives variation in root attributes.
