The concept of porous stainless steel microspheres was inspired by the intelligent design of functional structures present in nature and materialized with the help of the sol-gel technology. Porous metallic and/or ceramic microspheres can help in the development of conventional and advanced fuels, which can be used in technological devices (e.g., advanced nuclear reactors) for the generation of renewable energy, as renewable and safe sources of energy are required for the continuous civilizing evolution of the mankind. As a result of the above, some extra peculiarities of the synthesis and potential applications of the nanotechnological structure represented by the porous metallic microspheres are presented here.
