A novel ruthenium(II) complex with specific luminescent selectivity towards hybrid G-quadruplex DNA was developed that can easily be distinguished by the naked eye without further treatment.

Enantiomerically pure dinuclear ruthenium complexes with 1,2-dicarbonylhydrazide as a bridging ligand are optically active in the visible and near infrared spectral regions depending on the oxidation states of the metal centers and are useful as an electrochemically driven near infrared chiroptical switch.

The first (1)H, (13)C, (31)P and (11)B solid state MAS NMR studies of electron-deficient carborane-containing ruthenium and osmium complexes [Ru/Os(p-cym)(1,2-dicarba-closo-dodecaborane-1,2-dithiolate)] are reported. The MAS NMR data from these 16-electron complexes are compared to those of free carborane-ligand and an 18-electron triphenylphosphine ruthenium adduct, and reveal clear spectral d...

The synthesis, characterisation and catalytic behaviour of ruthenium indenylidene complexes bearing an N-heterocyclic carbene and triisopropylphosphite are described.

To the Editor: A recent article in PNAS by Asikainen and Werle (1) reports on the occurrence and morphology of ferromanganese nodules found in a New Hampshire lake. The authors offer data on the shapes, banding, composition, and distribution of the nodules and crusts. They also state that my paper (2) claims that the morphology of such nodules is controlled by elemental concentrations and that ...

babbitt is a white silvery alloy that composed of tin, lead, copper and antimony. this alloy is the most current bearing alloy in industrial applications. the characteristics of this alloy, such as high wearing resistance and low coefficient of friction, have converted it into a bearing cover. the target of this study is investigation on the effects of alloy elements on wearing and micro-struct...

It is now well-known that (2)H solid-state NMR techniques can bring a better understanding of the interaction of deuterium with metal atoms in organometallic mononuclear complexes, clusters or nanoparticles. In that context, we have recently obtained experimental quadrupolar coupling constants and asymmetry parameters characteristic of deuterium atoms involved in various bonding situations in r...

Tracer studies in healthy volunteers using stable isotopes of ruthenium were performed with the objective of extending the limited knowledge about the biokinetics of the radionuclides of this element. Tracer solutions were prepared starting from metallic ruthenium powders enriched in either Ru or Ru (isotopic enrichment ca. 98%). Tracer administration was followed by the collection of blood and...

A series of kinetic and structural investigations on ruthenium-based catalysts for asymmetric transfer hydrogenation (ATH) of ketones are reported. A method is reported for monitoring the formation of ruthenium hydride species in real time using (1)H NMR spectroscopy.

The reactions of Ru(bpy)2(CO3) (bpy=2,2 -bipyridine) and Ru(phen)2(CO3) (phen=1,10-phenanthroline) with the binucleating phenolato diimine function, OH C6H4 C(CH3) N CH2 C6H4 CH2 N (CH3)C C6H4 OH, H2L in ethanol solvent under dinitrogen atmosphere result in ruthenium bipyridine/phenanthroline heterochelates [Ru(bpy)2/(phen)2L ](ClO4) 1 where L corresponds to the ketonic imine function O C6H4C(C...
