ABSTRACT The large‐scale application of titanium is limited by its high production costs, as well as its low utilization and recycling rates. Therefore, efficient recovery of titanium scrap offers a viable pathway to reduce its cost. Molten‐salt electrolysis offers a promising route for upcycling titanium scrap, but the conventional method, which ...

ABSTRACT Transnational collaboration is critical for water‐security innovation, yet actor configurations and thematic priorities remain poorly characterized. We surveyed 92 Australian and Brazilian researchers from the Tropical Water Research Alliance (TWRA), analyzing 11 sets of binary variables on collaboration modes, stakeholders, implementation ...

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
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.

Striking a balance: Stakeholder perceptions of risk in horse racing
Abstract Background Thoroughbred racing is a major industry, and in recent years public concerns about equine safety have become more prominent, particularly in relation to on‐track injuries and fatalities. This has challenged the industry's social licence to operate (SLO).

喀斯特槽谷区在降雨过程中极易发生水土流失,这使得该区生态环境被破坏。以喀斯特槽谷区为研究对象,通过室内模拟其典型顺/逆层坡面特征及地下孔裂隙发育程度,利用人工降雨试验研究不同雨强条件下地表地下产流特征,从而揭示喀斯特槽谷区地表地下产流机制。结果表明:(1)喀斯特槽谷区地表地下产流受雨强影响,小雨强(30 mm/h)条件下地下产流量大于地表产流量,中雨强(60 mm/h)条件下地表产流量增大且裸坡条件下地表产流量大于地下产流量,大雨强(90 mm/h)条件下裸坡与顺层坡的地表产流量均大于地下产流量。(2 ...
