Conspectus Current projections for global mining indicate that unsustainable practices will
cause supply problems for many elements, called critical raw materials, in the next 20 years …

The synthesis of lanthanides other than cerium in the oxidation state+ IV has remained a
desirable but unmet target until recently, when two examples of TbIV with saturated …

The consensus is growing for the UN sustainable development goals regarding responsible
consumption, production, and climate actions. Because of growth towards a digital society …

Elucidating details of biology's selective uptake and trafficking of rare earth elements,
particularly the lanthanides, has the potential to inspire sustainable biomolecular …

The separation of rare‐earth ions from one another is challenging due to their chemical and
physical similarities. Nearly all rare‐earth separations rely upon small changes in ionic radii …

Isonicotinic acid (INA), as a prototypical N, O-donor bifunctional ligand, has demonstrated its
ability to differentiate Th4+ from representative ions for products in spent nuclear fuels (Cs+ …

Rare earth (RE) elements (scandium, yttrium, and the lanthanides) are critical for their role in
sustainable energy technologies. Problems with their supply chain have motivated research …

Lanthanides (Ln) are critical raw materials, however, their mining and purification have a
considerable negative environmental impact and sustainable recycling and separation …

Selective crystallization offers new opportunities for separating neodymium and dysprosium,
which are considerably important in permanent magnets. Two water-soluble nitrogen-rich …

Rare earth metal complexes of the proligand H3TriNOx ([(2-t BuNOH) C6H3CH2] 3N) have
been shown to afford separations of simple mixtures of rare earth metal salts. In particular …
