Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Germanium is a critical dispersed metal, yet sustainable recovery from dilute solutions is limited by sorbents that are difficult to regenerate and operate in continuous mode. Here, we fabricate a regenerable 3D‐printed hydrogel monolith (3D‐ATO‐GS) by integrating hydroxyl‐rich amorphous TiO2 nanoparticles into an alginate/gelatin scaffold ...

Policy &Internet, Volume 18, Issue 2, June 2026.ABSTRACT In an era of proliferating but divergent data protection regimes, the European Union's rights‐based approach and China's sovereignty‐centric model have become two dominant poles of global data governance. This article examines how multinational enterprises navigate compliance under these dual systems and how that compliance is shaped through ...

Shuitu Baochi Xuebao, 2021 为探究春季解冻期覆沙黄土坡面能量参数动态响应时空演化过程，在相同放水流量（1 L/min）条件下，采用2个土壤处理（未冻坡面，冻结坡面）和4个覆沙厚度（0，1，2，3 cm）进行室内模拟冷冻和放水冲刷试验，系统分析了径流流速（V）、径流功率（W）、单位径流功率（P）和径流动能（E）在不同土壤处理和不同覆沙厚度条件下的时空演化过程。结果表明：（1）不同处理下的径流流速随产流时间的延长总体呈下降趋势，随着距坡顶距离的增大总体呈增大趋势。未冻坡面和冻结坡面径流流速的均值在0.23~0.35，0.18~0.35

Too Difficult to Report? User Experiences With DSA and Community Guideline Reporting on Social Media
Policy &Internet, Volume 18, Issue 2, June 2026.ABSTRACT User reporting of norm‐violating content on social media is a crucial component of platform governance. While prior research has explored the motivations behind reporting—often drawing on the Bystander Intervention Model—less attention has been paid to how users navigate the processes involved.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Engineering of the catalyst interface and modulation of transition–metal d–band play critical roles in the electrocatalytic hydrogen evolution reaction (HER). Herein, a synthetic strategy is developed to fabricate nitrogen‐doped carbon nanotubes (N–CNTs)–supported Ni3Se4–CeO2 heterojunction catalysts through a facile chemical vapor deposition (

Intelligent Material Framework for Data Mining and Performance Prediction of Invar Alloy
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Invar alloys exhibit a low coefficient of thermal expansion (CTE) over a wide temperature range and are regarded as critical materials for precision engineering and aerospace applications. In this work, an integrated OLR‐IMF (an intelligent material framework based on optical character recognition [OCR], large language models [LLMs], and ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves

Structural Modulation of Magnetic Softness in Fe‐Based Amorphous Alloys via Pulse Current Training
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Fe‐based amorphous alloys, despite their intrinsically low magnetocrystalline anisotropy, suffer from quasi‐dislocation dipoles and localized stress fields that impede domain‐wall motion and increase coercivity. Here, we introduce pulse current training (PCT) as an energy‐efficient technique to overcome these limitations in a Fe76Si9B10P5 ...

Functional Ecology, Volume 40, Issue 6, Page 1725-1739, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...
