Thermoanalytical studies on the double complexes (M(NH3)6)(M'(CN)6) and (MCl(NH3)5)(Ni(CN)4)(M=Cr, Co, Ru, Rh; M'=Fe, Co).

MFM studies of interlayer exchange coupling in Co/Ru/Co films: Effect of Ru layer thickness.

Antiferromagnetically coupled magnetic thin films are promising candidates for the design of new magnetic storage and logic devices. The ability to control the interlayer thickness, therefore the magnetic reversal response, of exchange-coupled magnetic layers is of paramount importance in nanotechnology, especially in magnetic sensing element design and applications. In this work, magnetic forc...

CO adsorption on hydrogen saturated Ru „ 0001 ...

The interaction of CO with the Ru(0001)(131)H surface has been studied by density functional theory ~DFT! periodic calculations and molecular beam techniques. The hydrogen (131) phase induces an activation barrier for CO adsorption with a minimum barrier height of 25 kJ mol. The barrier originates from the initial repulsive interaction between the CO-4s and the Ru-d3z2-r2 orbitals. Coadsorbed H...

Chelation-assisted carbonylation reactions catalyzed by Rh and Ru complexes*

This account reviews chelation-assisted carbonylation reactions catalyzed by late transition metals. New carbonylation reactions are achieved with these catalysts in the presence of pyridin-2-ylmethanol and pyridin-2-ylmethylamine. The reactions involve activation of O−H and N−H bonds, coordination of the pyridine nitrogen to Rh being essential for the reaction to proceed. In addition, a new ty...

Magnetic antiphase domains in Co/Ru/Co trilayers

CO chemisorption and dissociation at high coverages during CO hydrogenation on Ru catalysts.

Density functional theory (DFT) and infrared spectroscopy results are combined with mechanism-based rate equations to assess the structure and thermodynamics of chemisorbed CO (CO*) and its activation during Fischer-Tropsch synthesis (FTS). CO* binding becomes weaker with increasing coverage on Ru(0001) and Ru201 clusters, but such decreases in binding energy occur at higher coverages on Ru201 ...
