Reported Radioactivity of Osmium [PDF]
Nature, 1948 FOR some time it has been known that two isobars which differ by unity in atomic number cannot both be stable, except for a possible influence of the neutrino if its mass has a positive value at rest. A search for radioactivity among the existing pairs of isobars led to the announcement1 of K-electron capture in osmium (Os187) with a half-life of about

Arene-Osmium(II) Complexes in Homogeneous Catalysis
Inorganics, 2021 Although the application of arene-osmium(II) complexes in homogeneous catalysis has been much less studied than that of their ruthenium analogues, different works have shown that, in some instances, a comparable or even superior effectiveness can be ...
