The organic ligand 3,4,3-LI(1,2-HOPO) forms an Es(III) coordination complex, enabling structural and spectroscopic studies
Discovered in the debris after the detonation of the first hydrogen bomb in 1952, einsteinium is a highly radioactive actinide. As it doesn’t occur on Earth naturally, little is known about its chemistry beyond the fact that it forms a few halide and oxide salts. Making more than just trace amounts of it means bombarding lighter elements with neutrons for a prolonged period of time – a process that can only be done at one place in the world, the high flux isotope reactor at Oak Ridge National Laboratory in Tennessee, US.

Since element 99 - einsteinium - was discovered in 1952 at the Department of Energy s Lawrence Berkeley National Laboratory (Berkeley Lab) from the debris of the first hydrogen bomb, scientists have performed very few experiments with it because it is so hard to create and is exceptionally radioactive. A team of Berkeley Lab chemists has overcome these obstacles to report the first study characterizing some of its properties, opening the door to a better understanding of the remaining transuranic elements of the actinide series.

New Diagnostic Isotope to Enhance Targeted Alpha Therapy for Cancer
Team brings a new tool for alpha therapy by developing a paired isotope option for PET scans
A multidisciplinary team of researchers have demonstrated production, purification, and potential for the 134Ce/134La in vivo generator as a PET imaging surrogate for 225Ac and 227Th radiotherapeutic agents.
December 22, 2020 Researchers in the DOE Isotope Program have developed an effective radionuclide, cerium-134, as a paired analogue of actinium and thorium that can be imaged using positron emission tomography (PET). Establishing a routine production pathway for cerium-134 is an essential step in advancing the use of the alpha emitters for cancer therapy.
