Two lower-oxidation state uranium cations can be readily combined in a robust, yet flexible and derivatisable, tetraaryloxide ligand framework, affording a new platform at which to use the multi-electron reductive capacity of the two actinide centres.

Studies of nuclear fission have been ongoing since the discovery of the process in 1938 by Hahn and Strassmann [1]. The actinide nuclide Pu has long been a case of interest, as spontaneous fission presents itself as a decay mechanism with significant probability, relative to other isotopes in the actinide region. This allows for quantitative comparisons between spontaneous and induced fission [...

Actinides, the last known group of the Periodic Table are the subject of a special interest, both practical and scientific. Though their use is mainly based on their unique nuclear properties, the electronic structure is of no little interest because it is of paramount importance in determining the physical and chemical properties of the actinides and their compounds. Despite the common tendenc...

Evaluation of nuclear data for JENDL Actinide File and High Energy Files is now in progress. JENDL Actinide File will contain evaluated nuclear data for 89 nuclides horn 2 0 8= to ‘5Fm including main fissile and fertile nuclides. The data are evaluated in the neutron energy region from 10‘5 eV to 20 MeV, by widely using theoretical calculations and systematic of parameters and cross sections. E...

Understanding the influence of electrons in partially filled f- and d-orbitals on bonding and reactivity is a key issue for actinide chemistry. This question can be investigated by using a combination of well-defined experimental measurements and theoretical calculations. Gas phase spectroscopic data are particularly valuable for the evaluation of theoretical models. Consequently, the primary o...

Actinide-based metal–organic complexes and coordination architectures encompass intriguing properties functionalities but are still largely unexplored on surfaces. We introduce the in situ synthesis of actinide tetrapyrrole under ultrahigh-vacuum conditions, both a metallic support 2D material. Specifically, exposure tetraphenylporphyrin (TPP) multilayer to an elemental beam thorium followed by...

[NC4H12][(UO2)6(H2O)2(SO4)7] is the first organically templated actinide sulfate with a three-dimensional framework structure; it has channels of dimensions 8.5 A x 8.5 A, running along the [001] direction, containing tetramethylammonium cations.
