Hierarchical Structured TiO2/Boron‐Doped Diamond for Efficient Photo‐Electrocatalytic Degradation
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The discharge of refractory organic dye wastewater poses a significant threat to the ecological environment, necessitating the development of efficient treatment technologies. Herein, a uniform TiO2 array (TiO2‐AR) electrode is fabricated using a combination of magnetron sputtering and a mask plate process with a boron‐doped diamond (BDD ...

Sexuality, Gender &Policy, Volume 9, Issue 2, May 2026.ABSTRACT Masculinity significantly influences men's health‐seeking behaviors, yet its intersection with legal frameworks and healthcare access in Sub‐Saharan Africa remains underexplored. This mixed‐methods study investigates how gender norms and structural barriers influence healthcare experiences among 60 middle‐aged men (aged 30–60 years) in Yaoundé,

Functional Ecology, Volume 40, Issue 5, Page 1428-1442, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...

Gaoya dianqi, 2004 向低密度聚乙烯中添加自由基清除剂能够有效地抑制电老化,因而改变了电老化过程中聚乙烯的空间电荷的分布。在直流预压和短路过程中,空间电荷量随老化时间呈线性增长。结合自由基清除剂在其它老化形式中的化学反应机理,详细讨论了自由基清除剂对聚乙烯电老化的抑制以及老化过程中空间电荷分布的影响。
