Effects of restoration practices on biodiversity in temperate and boreal forests
Conservation Biology, EarlyView.Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon
Conservation Biology, EarlyView.Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

Insights Into the Temperature‐Dependent Oxidation Mechanism of Metallic Cerium in H2O‐N2 Atmospheres
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Metallic cerium (Ce), a widely used surrogate for actinide metals, enables mechanistic studies of reactions in complex gas environments under controlled and safer laboratory conditions. Here, the oxidation behavior of Ce in H2O‐N2 mixed atmospheres was investigated from 200°C to 350°C using in situ thermogravimetry–mass spectrometry, in situ X‐

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Alkali metal (Li, Na, and K) batteries (AMBs) have attracted widespread attention in recent years because of their high theoretical specific capacity and attractive energy density. However, they still suffer from uncontrollable dendrite growth and sluggish conductivity during cycling, which lead to security issues and inferior cycling ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The design and synthesis of highly efficient electrochemical sensors are pivotal to electrochemical conversion technologies. This study successfully synthesized a composite material comprising two‐dimensional (2D) conductive MXene and nickel‐based metal–organic framework (Ni‐MOF) by stirring at room temperature.

Anatomical study on the chalkiness formation of early indica rice(早籼垩白米形成的形态解剖学的研究)
Zhejiang Daxue xuebao. Lixue ban, 2002 以浙733(多垩白)和中优早5号(少垩白)两个品种为实验材料,利用人工气候箱控温手段,在植株开花后4天分别移入高(37℃)、中(30℃)、低温(24℃)的人工气候箱控温栽培.采用Spurr树脂半薄切片的方法对垩白部位的细胞结构和淀粉粒整体形态进行观察研究.实验结果表明,温度越高,腹背径向的细胞越扁,细胞数目越多,越易导致垩白的发生;不同温度处理下中优早5号的淀粉粒大多为多角形,但温度越高,淀粉粒排列越疏松,且大小不均一;低温处理下浙733的淀粉粒大多为多角形,排列较为紧密,但大小不均一,中 ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT In Co‐based alloys, the γ phase is normally stable at high temperatures and the ε phase at low temperatures, and there is a martensitic transition on cooling to ∼417°C. In the γ/β dual‐phase CoCrAlY bond coat of turbine blade thermal barrier coating systems, we observed the opposite: γ remained stable at room temperature, yet it underwent a γ →

Jianzhu Gangjiegou Jinzhan, 2019 局部火灾下,网架结构升温具有明显的非均匀性,结构中温度高的杆件热膨胀受到温度较低杆件的约束,使得网架结构的部分杆件具有显著的约束杆件高温力学特征。基于局部火灾下网架结构力学反应全过程数值追踪技术,考察结构升温非均匀性、结构荷载比、火源位置和结构跨度影响因素下,网架结构杆件高温屈曲后强度对整体结构抗火极限承载力的贡献。研究表明:当结构温度分布非均匀系数η在0.2≤η0.5时,杆件高温屈曲后强度对结构抗火极限承载力的贡献先逐渐减小然后转变为逐渐增大。上述研究结论可为建立网架结构第2阶段失效准则提供理论依据。

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The demand for advanced aerospace components necessitates near‐α titanium alloys with enhanced high‐temperature performance and compatibility with additive manufacturing (AM). To address this, an in situ alloying strategy was employed to co‐modify a Ti‐6.5Al‐2Zr‐Mo‐V alloy with Si and Y during laser powder bed fusion.
