In the crystal structure of the title compound, [Ru(3)(C(9)H(11)P)H(2)(C(18)H(15)P)(CO)(8)], the triangular Ru(3) unit is capped with one mesitylphosphin-idene ligand. In the trigonal-pyramidal Ru(3)P core, one Ru(II) atom is coordinated by a triphenyl-phosphane ligand in a terminal fashion. Two hydride ligands bridge over two Ru-Ru bonds. These Ru-Ru bonds [2.9400 (4) and 2.9432 (4) Å] are sli...

The homogenous water oxidation catalysis by [Ru(terpy)(bipy)Cl](+) (1) and [Ru(terpy)(Me2bipy)Cl](+) (2) (terpy = 2,2':6',2''-terpyridine, bipy = 2,2'-bipyridine, Me2bipy = 4,4'-dimethyl-2,2'-bipyridine) under the influence of two redox mediators [Ru(bipy)3](2+) (3) and [Ru(phen)2(Me2bipy)](2+) (4) (phen = 1,10-phenanthroline) was investigated using Ce(4+) as sacrificial oxidant. Oxygen evoluti...

Polyacrylonitril (PAN)-supported chitosan (CS) nanocomposite membranes were prepared by cross-linking the CS with 3-aminopropyl-triethoxysilane (APTEOS) via sol-gel method. Pervaporative performances of the CS-SiO2/PAN membrane for dehydration of aqueous alcohol solutions were investigated. From SEM cross-sectional images of the membrane, the spongy pores and the finger-like pores we...

A novel work was performed for fabrication and modification of composite nanofiltration (NF) membrane by polymerization reaction between polyethyleneimine (PEI) and triphthaloyldechloride (TPC). the main purpose of this work was water treatment. polysulfone was applied as a main polymer of substrate. The result of reaction between PEI and TPC would be formation of polyamide layer on the membran...

The performance of commercial composite reverse osmosis membranes has been continuously improving, since its introduction in the late seventies. An additional significant improvement of membrane performance has been achieved at the beginning of 1995, when new composite polyamide brackish water RO membrane technology has been introduced. The new membrane material is characterized by a very high ...

Superconductivity and magnetism are typically antithetical forms of order. After all, in conventional superconductors, magnetic impurities are destructive to superconductivity as they break Cooper pairs [1]. But the discovery in 1979 of so-called heavy fermion superconductivity, found near an antiferromagnetic phase, led to a shift in thinking on this subject [2]. Since then, some of the most i...
