Revista Geografia, Literatura e Arte, 2018 A crise do conhecimento científico indica a necessidade de repensarmos o modelo uniforme de seu discurso na direção da abertura ao diálogo com outras linguagens e instâncias do saber humano, como a filosofia e, principalmente, as artes. Partindo desse pressuposto, faremos uso de alguns trechos do livro gráfico Do Inferno para analisarmos as ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The development of high‐voltage aqueous zinc‐ion batteries (AZIBs) is primarily hindered by the lack of suitable cathode materials and electrolytes that can work in broad voltage windows. Herein, we propose a synergistic strategy that concurrently addresses these challenges through the integration of an amorphous vanadium oxyphosphate/graphene

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.

Gongye shui chuli, 2017 用硝酸钙和氯化镧对磁铁矿进行改性，考察不同初始浓度、pH、作用时间对含磷废水的吸附效果，进而分析其吸附等温线及动力学特性。结果表明：Langmuir等温吸附方程能很好地描述其等温吸附特性，未改性、硝酸钙改性、氯化镧改性的磁铁矿对磷的吸附饱和量分别为0.068、0.409、2.157 mg/g；未改性、硝酸钙改性、氯化镧改性的磁铁矿分别在pH为12、pH为8~12、pH为4~10时，对磷的吸附效果较好；氯化镧改性磁铁矿对磷的去除率达95%以上且其吸附过程符合二级吸附动力学方程。

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.

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.
