A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

Rare Metals, EarlyView.
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.

Sugarcane nutrition under organomineral fertilizer, phosphate‐solubilizing bacteria, and reduced phosphate doses

Annals of Applied Biology, EarlyView.
Sugarcane phosphorus (P) availability is limited in tropical soils, requiring strategies to improve fertilizer efficiency. This study evaluated Bacillus velezensis UFV 3918 (Bv) in combination with an organomineral fertilizer (OF) at reduced monoammonium phosphate (MAP) doses. It showed that Bv + OF + 1/3 MAP achieved soil and plant P levels comparable

Influences of Aluminum Ash Slag on Mechanical and Microstructural Characteristics of Stabilized/Solidified Heavy Metal Contaminated Soils

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Solidification/stabilization (S/S) is a widely adopted remediation technique for contaminated soils. However, how to efficiently and economically modify contaminated soil remains challenging. In this study, secondary aluminum ash slag (AAS) was employed as a novel stabilizer for the S/S treatment of lead (Pb) and zinc (Zn) contaminated soils.
