The Merrifield solid-phase peptide synthesis technique has been adapted to the synthesis of homo- and heterometallic metal−organic complex arrays (MOCAs). A terpyridine-appended and Fmoc-protected L-tyrosine derivative was metalated with Pt(II), Rh(III), or Ru(II) ions in solution and sequentially coupled at the surface of functionalized polymeric resin to give a metal complex triad (Rh−Pt−Ru),...

The electrosorption and catalytic properties of bare and Pt modified Ru(0001) and Ru(10−10) single crystal surfaces and carbon supported Ru nanoparticles have been studied by electrochemical, surface X-ray scattering, scanning tunneling microscopy, Fourier transform infrared spectroscopy and high resolution transmission electron microscopy techniques. The electrochemical surface oxidation of Ru...

Ultrafast time-resolved infrared spectroscopy of [Ru(bpy)3]2+ (bpy = 2,2'-bipyridine), [Ru(mbpy)3]2+ (mbpy = 6-methyl-2,2'-bipyridine) and [Ru(mphen)3]2+ (mphen = 2-methyl-1,10'-phenanthroline) in deuterated acetonitrile serves to elucidate the evolution of the system following pulsed excitation into the 1MLCT band at 400 nm. While for [Ru(bpy)3]2+ no intermediate state can be evidenced for the...

A novel tris heteroleptic dipyridophenazine complex of ruthenium(II), [{Ru(phen)(dppz)(bpy'-his)}{Ru(NH3)5}]5+, containing a covalently tethered ruthenium pentammine quencher coordinated through a bridging histidine has been synthesized and characterized spectroscopically and biochemically in a DNA environment and in organic solvent. Steady-state and time-resolved luminescence measurements indi...

Background. Four of the most relevant gestures in rugby (RU) are the pass, the tackle, the line out, and the scrum. RU is the third most common contact sport on the planet, and being a fast-paced collision game and carries a high risk of injury. Objectives. To describe and compare plantar dynamics during four sports gestures in rugby players through speed, strength, and balance. Methods. Twen...

The structure of the commensurate (23x23) phase of graphene on Ru(0001) has been analyzed by quantitative low-energy electron diffraction (LEED)-I(V) analysis and density-functional theory calculations. The I(V) analysis uses Fourier components as fitting parameters to determine the vertical corrugation and the lateral relaxation of graphene and the top Ru layers. Graphene is shown to be strong...

Complexes containing a Ru(2)(n+) core (n = 4, 5 or 6) have been of great interest because of their variety of electronic configurations and magnetic properties. Herein, we report a novel homovalent Ru(2)(6+)-based complex, (H(2)pip)(2)[Ru(2)(hedp)(2)Cl(2)]·6H(2)O (pip = piperazine) (1), isolated by the direct reaction of the mixed-valent Ru(2)(5+)-based anion Ru(2)(hedp)(2)(3-) [hedp = 1-hydrox...

We report an oscillation of the giant magnetoresistance GMR ratio as a function of Ru layer thickness in the CoFe/Cu/ CoFe/Ru/CoFe SAF/Cu/CoFe/IrMn dual spin valve SV structure. A normal GMR with a positive sign is observed for the thickness of Ru providing a ferromagnetic interlayer exchange coupling IEC . The inverted GMR is observed for the thickness of Ru providing an antiferromagnetic IEC,...
