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

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.

A Review of the Strategies Used in the Recovery and Passivation of Lead in Lead‐Based Perovskite Solar Cells: Balancing Device Efficiency, Toxicity, and Environmental Sustainability

Natural Sciences, Volume 6, Issue 1, January 2026.
Lead‐based perovskite solar cells deliver outstanding power conversion efficiencies, yet their commercialization is constrained by concerns over lead toxicity and stability challenges. Advanced encapsulation and chemical passivation techniques can significantly suppress lead leakage while improving long‐term device stability.

Impact of Pulp Density on Extraction of Metals, By Acidithiobacillus ferrooxidans and Pseudomonas fluorescens from Bauxite Ore

, 2018
Mineral ores are the non-renewable resources of various metals. The extraction of metals is done only from the Ist and IInd grade ore particles and rest is left as such because of low metal content.

Pyrite oxidation under initially neutral pH conditions and in the presence of Acidithiobacillus ferrooxidans and micromolar hydrogen peroxide [PDF]

, 2012
Hydrogen peroxide (H2O2) at a micromolar level played a role in the microbial surface oxidation of pyrite crystals under initially neutral pH. When the mineral-bacteria system was cyclically exposed to 50 μM H2O2, the colonization of Acidithiobacillus ...
