Here two major themes are presented in which one explores the structural properties of U(VI) uranyl germanates as they relate to U(VI) uranyl silicates and the emergence of cation-cation interactions as a structural feature, and the other offers a glimpse at the behavior of Np(V) and U(VI) during the growth of rock- forming minerals for the purpose of understanding the inorganic controls of crystal growth on environmental remediation. cache/x346d22086w.txt txt/x346d22086w.txt
