We argue that SS is coming of age, but more integrative and concerted efforts are still needed to further consolidate its identity by developing a coherent and rigorous scientific core. Keywords: sustainability science; sustainable development; definition; core questions; thematic framework; ...
Metallacarboranes are 3-dimensional cluster compounds that in general can exist in a number of isomeric forms which cannot always be distinguished spectroscopically, in which case crystallographic study is the essential experimental technique [4]. A good example concerns the icosahedral metallacarborane...
