Conventional wisdom among chemists has been that most lanthanide elements could exist in compounds only in the +3 oxidation state. Overturning that long-standing assumption, researchers have now ...

What do magnets, smartphones and medical imaging devices have in common? They all depend on rare earth elements called lanthanides, which are vital for modern technology. Yet, separating these ...

Lanthanides are a class of rare earth elements that in many countries are added to fertilizer as micronutrients to stimulate plant growth. But little is known about how they are absorbed by plants or ...

Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste ...

UV-Visible-NIR microspectroscopy brings together high spatial resolution of microscopy and the spectral analysis capabilities of spectroscopy, encompassing the ultraviolet (UV), visible and ...

(Nanowerk News) The discovery of carbon nanostructures like two-dimensional graphene and soccer ball-shaped buckyballs helped to launch a nanotechnology revolution. In recent years, researchers from ...

Lanthanides are rare-earth heavy metals with useful magnetic properties and a knack for emitting light. Researchers had long assumed that lanthanides' toxicity risk was low and therefore safe to ...
