Uranium chemistry is beautiful. This object is inspired in a new class of uranium oxide molecules discovered by Prof. Burns (U. Notre Dame, IN, USA) in 2005. Known as U20, this molecule is like a dodecahedron cage, which is built from twelve fused pentagonal rings. It comprises 20 uranium atoms and 100 oxygens lying at each vertex of the wireframe mess. Printed in polished nickel steel. Use it as pendant or keychain.
