In the crystal structure of the title compound, [Ru(2)(C(14)H(17)O)(2)(CO)(4)], each Ru(I) atom is connected to one end-on and two bridging carbonyl groups and one cyclo-penta-dienyl ring. The two Ru atoms are connected into binuclear complexes via two bridging carbonyl groups, forming four-membered rings which are located on centres of inversion. The Ru-Ru distance of 2.7483 (11) Å corresponds...

Activity improvement of Ru-based catalysts is needed for efficient production of valuable chemicals from glycerol hydrogenolysis. In this work, a series of Re promoted Ru catalysts encapuslated in porous silica nanoparticles (denoted as Re-Ru@SiO₂) were prepared by coating silica onto the surface of chemically reduced Ru-polyvinylpyrrolidone colloids, and were used to catalyze the conversion of...

While the catalytic activity of some Ru-based polypyridine complexes in water oxidation is well established, the relationship between their chemical structure and activity is less known. In this work, the single site Ru complex [Ru(bpy)2(H2O)2] (bpy = 2,2′-bipyridine)—which can exist as either a cis isomer or a trans isomer—is investigated. While a difference in the catalytic activity of these ...

Accelerated deactivation of Co/Al2O3 catalysts in Fischer-Tropsch synthesis and the effect of Re and Ru as the catalytic promoters are reported. 15wt% Co/Al2O3 catalyst and 1wt% Ru and 1.4wt% Re  promoted cobalt catalysts have been formulated and extensively characterized. The deactivation of the unpromoted cobalt catalyst and those promoted with ...

In recent years, the field of metal-based drugs has been dominated by other existing precious metal drugs, and many researchers have focused their attention on the synthesis of various ruthenium (Ru) complexes due to their potential medical and pharmaceutical applications. The beneficial properties of Ru, which make it a highly promising therapeutic agent, include its variable oxidation states,...

BACKGROUND Nurses' research utilization (RU) as part of evidence-based practice is strongly emphasized in today's nursing education and clinical practice. The primary aim of RU is to provide high-quality nursing care to patients. Data on newly graduated nurses' RU are scarce, but a predominance of low use has been reported in recent studies. Factors associated with nurses' RU have previously be...

In the title complex, [Ru(C6H14O2PS2)3], the coordination environment of the Ru(III) atom is distorted octa-hedral, defined by six S atoms from three S,S'-bidentate diisopropyl di-thio-phosphate ligands. The average Ru-S bond length is 2.41 (1) Å and the average S-Ru-S bite angle is 81.13 (19)°.

The pyrochlore solid solution (Na(0.33)Ce(0.67))2(Ir(1-x)Ru(x))2O7 (0≤x≤1), containing B-site Ru(IV) and Ir(IV) is prepared by hydrothermal synthesis and used as a catalyst layer for electrochemical oxygen evolution from water at pH<7. The materials have atomically mixed Ru and Ir and their nanocrystalline form allows effective fabrication of electrode coatings with improved charge densities ov...

Cubic cage compounds composed of Co-CN-Ru linkages have been prepared which illustrate the following features: (i) new motifs for alkali metal ion complexation (i.e., cationic receptors for cations), (ii) a new family of triaza-metalloligands, and (iii) a double box-like cage. The cages are synthesized by the condensation of [CpCo(CN)3] and [Cp*Ru(NCMe)3] (cyclopentadienyl, Cp; pentamethylcyclo...

Oxygen reduction kinetics on bare and Pt-modified Ru(10/1̄/0) and Ru(0001) single crystal surfaces, and on carbon-supported Ru nanoparticles have been investigated. Spontaneous deposition of Pt was used to form approximately 1.5 and 0.5 monolayers on Ru single crystals and nanoparticles, respectively. The reaction kinetics of O2 on single crystal surfaces has a small structural dependence. It is...
