Tyler did a fantastic job on this one. A deep dive into the chemistry and physics of transplutonium elements #fblockrocks journals.aps.org/rmp/abstrac…

Pressure effects on metals, alloys, and compounds of transplutonium elements

Materials containing transplutonium elements (the actinides Am--Cm that come after Pu in the periodic table) are important for nuclear power, nuclear waste management, and long-term storage. They...

Sm2 is reactive as hell. Pressure just makes it worse pubs.acs.org/doi/10.1021/acs…

Pressure-Induced Reduction of Dicyanamide by Samarium(II) in a Coordination Polymer

A samarium(II) coordination polymer, [Sm(2.2.2-cryptand)(dca)]I (dca− = dicyanamide), has been prepared from the reaction of SmI2 with tetrabutylammonium dicyanamide and 2.2.2-cryptand. The structure...

Neptunium (Np3 ) has a beautiful alexandrite effect. Left is one lab, center is natural sunlight, and right is a lab under fluorescent lighting. 5f-5f transitions are magical. This is the same solution. Some great pics taken by @jp_brannon #fblockrocks #actinides
