The recycling of material containing precious metals can lead to the entry ruthenium into copper electrowinning process, by so far unknown effects. There, is oxidized highly volatile tetroxide. In order avoid losses during electrolysis, oxidation behavior in was investigated testing different oxygen overvoltages using alloy and diamond anodes. Furthermore, temperature current density were varie...

A number of new ruthenium compounds have been synthesised, isolated and characterised, which exhibit excellent cytotoxicity against a number of different human tumour cell lines including a defined cisplatin resistant cell line and colon cancer cell lines. Addition of hydrophobic groups to the ruthenium molecules has a positive effect on the cytotoxicity values. Evidence is provided that, after...

The organic chemistry of ruthenium has been one of the most vigorously growing research areas over the past decades. Considerable effort has been extended towards the design and application of a broad series of ruthenium complexes, which culminated with the development by Ryoji Noyori (2001 Nobel Prize for Chemistry) of chiral ruthenium catalysts for stereoselective hydrogenation reactions [1],...

Presently, there is large interest in analysing the interactions in vitro with plasma proteins of some novel antitumor ruthenium(III) complexes that are in preclinical or clinical phase. The joint application of separation and spectroscopic techniques provides valuable information on the nature and the properties of the resulting ruthenium/protein adducts. Recent work carried out in our laborat...

normal 0 false false false en-us x-none ar-sa background: from the thousands of years, metal compounds have been used in medicine for treatment of various diseases including various types of cancers. ruthenium was seen as a promising metal due to its similar kinetics to platinum and its lower toxicity. therefore, we aimed to evaluate the newer mononuclear ruthenium (ii) compounds for antinocice...

The tetraruthenium polyoxometalate water oxidation catalyst 1 performs very fast hole scavenging from photogenerated Ru(iii) polypyridine complexes, both in homogeneous solution and at a sensitized nanocrystalline TiO(2) surface.

Ruthenium phosphido complexes have been shown to be excellent nucleophiles, reacting via two-electron processes with a variety of electrophiles. A catalytic alkylation reaction was developed using an achiral ruthenium complex, which was then elaborated into a catalytic enantioselective synthesis of P-stereogenic phosphines. These useful and synthetically challenging phosphines can now be access...

Ruthenium is a fission product that can be released from the fuel in case of a severe nuclear accident. In this work the impact of the atmosphere composition, including air radiolysis products, on the transport of ruthenium through a primary circuit was examined. Experiments were performed at temperatures 1300, 1500 and 1700 K in a slightly humid air. In the experiments significant effect of ni...

The ruthenium hydride of (Ar(4)CpOH)Ru(CO)(2)H exchanges cleanly and rapidly with D(2) at room temperature to generate the ruthenium deuteride. A chain mechanism is proposed to explain the much more rapid exchange of RuH/D(2) than RuCO exchange with (13)CO.
