Expanding on the ability of trivalent actinides to support microbial alcohol metabolism in evolved methylotrophic bacterium [PDF]

open access: yesCommunications Chemistry
The 4 f elements, known as the lanthanides, have only recently been recognized as biologically essential metals. These elements can be found in the active site of certain alcohol dehydrogenase (ADH) enzymes, which are used by methylotrophic bacteria to ...

Neodymium as Metal Cofactor for Biological Methanol Oxidation: Structure and Kinetics of an XoxF1-Type Methanol Dehydrogenase

open access: yesmBio, 2021
Lanthanides comprise a group of 15 elements with atomic numbers 57 to 71 that are essential in a variety of high-tech devices, such as mobile phones, but were considered biologically inert for a long time.

Lanthanides: a focused review of eutectic modification in hypoeutectic Al–Si alloys

open access: yesJournal of Materials Research and Technology, 2020
A modified fibrous-like eutectic structure strongly improves the final mechanical properties of Al–Si foundry alloys, especially ductility. Beside widely used commercial eutectic modifiers such as Sr and Na, lanthanides appear to be a possible ...

Optimization of cerium/praseodymium separation parameters with the aim of production of pure beta-emitter radioisotope 143Pr for therapeutic application in nuclear medicine [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2023
In this study, an effective and efficient separation method for separating praseodymium from cerium was designed, optimized, and successfully implemented. In this method, a special adsorbent for lanthanides (Ln-resin with dimensions of 100 to 150 microns)

Use of lanthanides to alleviate the effects of metal ion-deficiency in Desmodesmus quadricauda (Sphaeropleales, Chlorophyta).

open access: yesFrontiers in Microbiology, 2015
Lanthanides are biologically non-essential elements with wide applications in technology and industry. Their concentration as environmental contaminants is, therefore, increasing.

Lanthanide-Dependent Regulation of Methylotrophy in Methylobacterium aquaticum Strain 22A

open access: yesmSphere, 2018
Methylobacterium species are representative of methylotrophic bacteria. Their genomes usually encode two types of methanol dehydrogenases (MDHs): MxaF and XoxF.

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

open access: yesScientific 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 ...

Bio-mining of Lanthanides from Red Mud by Green Microalgae

open access: yesMolecules, 2019
Red mud is a by-product of alumina production containing lanthanides. Growth of green microalgae on red mud and the intracellular accumulation of lanthanides was tested. The best growing species was Desmodesmus quadricauda (2.71 cell number doublings/day)
