Ruthenium is making deals with Israeli banks to buy their vaults and secured rooms and offer the service directly to customers.
announced that it will invest in enhancing the ruthenium (Ru) refining capability of its Tsuchiura Plant (located at Sawabe in Tsuchiura City, Ibaraki).
At E [approximately equal to] 0 V RHE the hydrogen adsorption reaction occurs on the onefold coordinatively unsaturated ruthenium site (in short: 1f-cus Ru) and the bridging oxygen atom.
Hence, this requires structureproperty relationships to be formulated, starting with the explanation of small changes, which can then be applied to the larger more complex systems for the advantageous properties of ruthenium complexes as novel inorganic therapeutics to fully realise the processes, which govern the reactivity of the complexes, must be clearly established.
In a statement, Mayak denied that its plant was the source of increased level of ruthenium 106.
A typical procedure was as follows: (1H-benzo[d]imidazol-2-yl)ethanol aqueous solution (0.1 mol/L), ruthenium complex catalyst (1 x [10.sup.-4] mmol, 0.01 mol% based substrate), and 0.2mmol (inert internal standard) were added into a reaction tube.
