Using their bulk moduli -which increase with increasing osmium content showing a deviation from linearity- and after employing a thermodynamical model it was concluded that the bulk modulus for osmium is slightly smaller than that for diamond. Here, a similar conclusion is obtained upon employing an alternative model, thus strengthening the conclusion that osmium is the densest but not the most incompressible ele","authors_text":"E. S.
