21. The 103 Ru and 106 Ru will render the fission ruthenium very radioactive. 22. In this case, the ruthenium complex acts as both photosensitizer and catalyst. 23. It does not contain rhenium or ruthenium and its nickel content is limited. 24. It was formerly known as the'ruthenium -106 tank arrangement '. 25. There are many studies of individual molecular behavior on ruthenium in surface science. 26. The presence of ruthenium in this reaction lessens the yield of filamentous carbon. 27. Ruthenium has four crystal modifications and does not tarnish unless subject to high temperatures.28. Ruthenium was first discovered in the form of ruthenium oxide in a similar manner.29. Ruthenium was first discovered in the form of ruthenium oxide in a similar manner. 30. New catalysts based on ruthenium ( IV ) oxide have been developed by Sumitomo.
