| Finally, a relatively small amount of rhenium is used to make catalysts for the petroleum industry. |
| General Electric, one of the world's biggest makers of jet engines, has spent years developing nickel-based superalloys to replace rhenium. |
| Her PhD research was design, synthesis, chemical and structural characterization of rhenium and technetium complexes for the development of diagnostic and therapeutic agents in nuclear medicine. |
| Its melting and boiling points are third highest among all elements after tungsten and rhenium. |
| The present invention relates to a heterogenic rhenium containing catalyst suited particularly to the metathetic reactions of hydrocarbons. |
| The chemical properties of this silvery gray, crystalline transition metal are intermediate between rhenium and manganese. |
