Quantum chemistry and simulation help characterize coordination complex of elusive element 61
When element 61, also known as promethium, was first isolated by scientists at the Department of Energy's Oak Ridge National Laboratory in 1945, it completed the series of chemical elements known as lanthanides. However, aspects of the element's exac.....»»
Study proposes new constraints on exotic spin-spin-velocity-dependent interactions between electron spins
