Actinium-225 (t1/2 = 9.9 days) and thorium-227 (t1/2 = 18.7 days) are the preeminent candidates for Targeted Alpha Therapy (TAT), where alpha-emitting radionuclides are chemically coupled to targeting vectors in order to deliver high linear energy transfer (LET) radiation to nearby tissue…

Low-valent Ln(II) and An(II) have been isolated and characterized in solid-state complexes…

Prior to the Antibiotic Era, infectious disease was leading cause of human morbidity and mortality throughout human history. However, with the advent of the first antibiotics pathogens evolved resistance mechanisms…

Uranium complexes are of considerable interest both in fundamental actinide chemistry and in nuclear technologies from uranium nuclear fuels to chemical separation processes…

The need for relativistic Hamiltonians in the calculation of the electronic structure of heavy elements is already well established. For calculating X-ray spectroscopies, such as absorption (XAS) and emission (XES), these effects are even more pronounced due to the participation of core electrons…

Curium oxides are stored for extensive periods before their incorporation into target fabrication processes, likely degrading during this time. This work investigates the characterization of Cm oxides and its stable surrogates—Nd and Ce—during these storage periods…

The actinide—fluorine bond is of particular interest due to the role of actinide fluorides in the nuclear fuel cycle. Moreover, the covalent character of these bonds is of fundamental interest to actinide bonding…

Developing isotope production and separation methods for radiotherapeutic technologies has potential for transformative impact. In these interventions, radioisotopes deliver destructive radiation to diseased cells…

The characterization of structure and solvent exaction behaviors of the later trivalent actinides (An(III)) in comparison to the trivalent lanthanides (Ln(III)) is crucial to gaining further insight into the bonding behavior of the _f_-elements…

The efficient recovery and recycling of rare earth elements (REEs) is critical for supporting sustainable energy solutions. However, optimizing the separation of f-elements is complex, requiring exploration of numerous experimental factors and vast chemical spaces…
