Minor Actinides Can Replace Essential Lanthanides in Bacterial Life** [PDF]

, 2023
Certain f-block elements—the lanthanides—have biological relevance in the context of methylotrophic bacteria. The respective strains incorporate these 4 f elements into the active site of one of their key metabolic enzymes, a lanthanide-dependent ...

Taking Lanthanides out of Isolation: Tuning the Optical Properties of Metal-Organic Frameworks [PDF]

, 2020
Metal organic frameworks (MOFs) are increasingly used in applications that rely on the optical and electronic properties of these materials. These applications require a fundamental understanding on how the structure of these materials, and in particular

Selective removal of some heavy metals from Lanthanide solution by graphene oxide functionalized with sodium citrate

Scientific Reports, 2022
Lanthanides are widely used in several advanced technologies, and the presence of heavy metal ions as traces reduce their efficiencies. Hence, adsorption of some heavy metals from Lanthanides aqueous solution using previously prepared graphene oxide ...
