Carbon dioxide is a gas that is changing our environment. Its role as a greenhouse gas is clear with the onset of global warming. In efforts to address this issue, ambitious and creative schemes are targeting materials including zeolites, silica gels, aluminas, and activated carbons, as well as sophisticated metal–organic frameworks (MOFs) for the benign capture and storage of carbon dioxide. A...

The heterobimetallic complexes [(eta5-C5H5)Ru(CO)(mu-dppm)Mn(CO)4] and [(eta5-C5Me5)Ru(mu-dppm)(mu-CO)2Mn(CO)3] (dppm = bis-diphenylphosphinomethane) have been prepared by reacting the hydridic complexes [(eta5-C5H5)Ru(dppm)H] and [(eta5-C5Me5)Ru(dppm)H], respectively, with the protonic [HMn(CO)5] complex. The bimetallic complexes can also be synthesized through metathetical reactions between [...

The kinetics of ruthenium thin film deposition via the hydrogen assisted reduction of bis(2,2,6,6-tetramethyl-3,5-heptanedionato)(1,5-cyclooctadiene)ruthenium(II) [Ru(tmhd)2cod] in supercritical carbon dioxide was studied. Deposition temperature was varied from 240 C to 280 C and the apparent activation energy was determined to be 45.3 kJ/mol. Deposition rates up to 30 nm/min were attained. The...

Neutral or cationic arene ruthenium complexes providing both hydrophilic as well as hydrophobic properties due to the robustness of the ruthenium-arene unit hold a high potential for the development of metal-based anticancer drugs. Mononuclear arene ruthenium complexes containing P- or N-donor ligands or N,N-, N,O- or O,O-chelating ligands, dinuclear arene ruthenium systems with adjustable orga...

The ruthenium complexes are known for their anticancer property. Some ruthenium complexes can bind with protein that may be related to the anticancer activity. The protein binding features of few ruthenium complexes have been analyzed to understand the amino acid selectivity within protein sequences. The docking, Molecular mechanics and QM/MM methods are used to predict the binding sites of the...

Piranha solution is a highly acidic mixture of sulfuric acid and hydrogen peroxide. The present study aimed at developing dimensionally stable anode (DSA), made titanium metal foil coated with Ruthenium Dioxide (RuO2), for the electrochemical oxidation peroxide in presence strong under ambient conditions. Results showed that piranha was fully degraded 5 h constant current 2 A (or density 0.32 A...

Sarcoplasmic reticulum Ca(2+)-ATPase has previously been shown to bind and dissociate two Ca2+ ions in a sequential mode. This behaviour is confirmed here by inducing sequential Ca2+ dissociation with Ruthenium Red. Ruthenium Red binds to sarcoplasmic reticulum vesicles (6 nmol/mg) with a Kd = 2 microM, producing biphasic kinetics of Ca2+ dissociation from the Ca(2+)-ATPase, decreasing the affi...

BACKGROUND The new ruthenium(II)-arene complex, which bearing a carborane unit, ruthenium and ferrocenyl functional groups, has a novel versatile synthetic chemistry and unique properties of the respective material at the nanoscale level. The ruthenium(II)-arene complex shows significant cytotoxicity to cancer cells and tumor-inhibiting properties. However, ruthenium(II)-arene complex of mechan...
