Handbook on the Physics and Chemistry of Rare Earths: Including Actinides, Volume 56, is a continuous series of books covering all aspects of rare earth science, including chemistry, life sciences, materials science and physics. The book's main emphasis is on rare earth elements [Sc, Y, and the lanthanides (La through Lu], but whenever relevant, information is also included on the closely related actinide elements. Individual chapters in this release include Lanthanide Molecules for Spin-based Quantum Technologies, Modeling Intramolecular Energy Transfer in Lanthanide Chelates: A Critical Review and Recent Advances, and Superconducting Uranium-Based Materials.
