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.

Tentative Approaches for Extraction of Lanthanides from Wastewater with Low Metal Concentration

open access: yesMembranes, 2023
Lanthanides are critical elements, and their recovery from wastewater increases the availability of these elements and reduces their impacts on the environment.

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.

A summary of the variations in relative abundance of the lanthanides and yttrium in allanites and epidotes [PDF]

open access: yesBulletin of the Geological Society of Finland, 1985
Recalculation of 506 analyses of allanites and 53 analyses of epidotes has confirmed that these minerals preferentially concentrate the light lanthanides, but that the relative concentrations vary considerably with variation of the host rocks, with ...

Lanthanides Release and Partitioning in Municipal Wastewater Effluents

open access: yesToxics, 2022
The use of lanthanides is increasing in our society, whether in communication technologies, transportation, electronics or medical imaging. Some lanthanides enter urban wastewater and flow through municipal wastewater treatment plants (WWTPs).
