Developing highly efficient recovery materials for precious 'rare earth metals' and improving resource circulation for digital infrastructuresource:eurekalertKorea imports 95% of its core minerals such as lithium, nickel, and rare earths. Rare earths, in particular, are characterized by chemical, electrical, magnetic, and luminescent properties that can be achieved by adding only a small amount, and their use has recently increased significantly as core materials in the eco-friendly automobile and renewable energy industries. China, a major producer of rare metals, is controlling the s...

Valorisation of acid mine drainage: Studying biosorption and bioaccumulation of rare earth elements by seaweeds source:sciencedirectAbstractAcid mine drainage (AMD) nature, persistence and the considerable amount of toxic elements cause significant environmental damage. Traditional passive treatment systems typically focus on neutralizing AMD using limestone and removing common toxic metal(loid)s, and often overlook the recovery of economic and strategic elements (e.g., rare earth elements (REEs)). This study is aimed at assessing for the first time the use of seaweeds to remove REEs from...

source:phys.orgLight alkanes are relatively simple molecules made entirely of carbon and hydrogen, arranged in linear or branching structures. Their oxidized counterparts, which include alcohols, epoxides, ketones, and aldehydes, are ubiquitous in the chemical industry, as they serve as essential starting materials in the synthesis of commodity substances, fine chemicals, agrochemicals, and pharmaceuticals. However, the selective oxidation of light alkanes remains a significant challenge.To date, scientists have explored various types of catalysts for this task. Although some offer decent perf...
