Land tenure contributions to protected area growth under alternative conservation targets in the Australian monsoon tropics. [PDF]
Conserv BiolAbstract As the global protected area (PA) network expands to meet international targets, it is important to assess whether traditional reliance on public land will suffice for projected PA growth or whether other tenures, such as Indigenous or pastoral lands, may increasingly contribute.

Interdependencies between Indigenous peoples, local communities, and freshwater systems in a changing Amazon. [PDF]
Conserv BiolAbstract Globally, Indigenous peoples and local communities (IPs and LCs) are fighting for the recognition of their knowledge and decision‐making authority in freshwater conservation. In the Amazon, decision‐making around freshwater management and conservation has often overlooked Indigenous and local knowledge (ILK) and the connections between ...

Journal of Accounting Research, Volume 64, Issue 1, Page 417-475, March 2026.ABSTRACT We study how foreign investors’ access to corporate information varies with pairwise geopolitical tensions between the investor's and investee's countries. Using a sample of 1,760 country‐pairs, we find that geopolitical tensions between a conference call host firm's country and a foreign country relate negatively with investor participation ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Nanocomposite permanent magnets with reduced rare‐earth content represent a promising class of materials for next‐generation high‐performance applications. However, asynchronous precipitation of soft and hard magnetic phases often results in grain size mismatch and limited coercivity.

Novel Non‐Equimolar High‐Entropy Zirconates With Superior Thermophysical Properties
Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Rare‐earth zirconates (RE2Zr2O7) are promising candidates for topcoat materials in thermal barrier coatings (TBCs). However, their practical application in TBCs is limited by poor fracture toughness and low thermal expansion coefficient (TEC).

Optimized Copper Distribution and Enhanced Coercivity in PrO2‐Doped Sm2Co17‐Type Magnets
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT A rational design of Cu distribution is crucial for achieving optimal magnetic properties in Sm2Co17‐type magnets. In this study, nanostructured PrO2 powders were employed to induce Cu redistribution at grain boundaries while preserving the cellular microstructure. The corresponding coercivity (Hcj), remanence (Br), and maximum energy product (

保水保肥材料对废弃离子型稀土矿区尾砂土壤理化性质及皇竹草生长的影响
Shuitu Baochi Xuebao, 2023 针对废弃稀土矿区氨氮减低后的土壤结构性差、肥力低下和种植植物生产力低的问题,土壤改良成为快速提升植被恢复的关键。通过田间试验,比较单施不同浓度保水剂(S1、S2、S3)和保水保肥材料(F1、F2、F3)对土壤理化性质、皇竹草生长以及作物耗水和水分利用效率(WUE)等相关指标影响,并运用主成分分析和模糊隶属度函数方法筛选出最佳改良材料。结果表明:(1)保水保肥材料通过改善废弃稀土矿区尾砂土土壤理化性质,促进皇竹草生长,土壤理化性质与植物生长的关系表现为土壤pH和养分含量越高,皇竹草分蘖数、氮磷含量 ...
