Binding of Organometallic Ruthenium(II) Anticancer Compounds to Nucleobases: A Computational Study

Ursula Röthlisberger, Ivano Tavernelli, Christian Gossens

The reaction of the anticancer compound (eta(6)-benzene)Ru(en)(OH2) (1) toward the nucleobases guanine, adenine, and cytosine is studied computationally using DFT/BP86 calculations. The aqua leaving group of such compounds is known to undergo ligand ...

Electrospray ionization mass spectrometry

Michel Prudent

Metal ions are essential elements in all living systems. Their detections and identifications in biological processes require different methodologies. Mass spectrometry is one of the commonly used techniques in bioinorganic analyses to fulfill these requir ...

Homo- and Heterodinuclear Helicates of Lanthanide(III), Zinc(II) and Aluminium(III) Based on 8-Hydroxyquinoline Ligands

Jean-Claude Bünzli, Frédéric Gumy

Homonuclear helicates with rare-earth-metal(III) ions or heteronuclear derivatives with rare-earth-metal and aluminium or zinc centres are obtained in alkali-metal-templated selfassembly processes from isobutenylidene- bridged homoditopic bis(2-carb-Gamido ...

Oxidation of iodide and iodine on birnessite (delta-MnO2) in the pH range 4-8

Urs von Gunten

The oxidation of iodide by synthetic birnessite (delta-MnO2) was studied in perchlorate media in the pH range 4-8. Iodine (I-2) was detected as an oxidation product that was subsequently further oxidized to iodate (IO3-). The third order rate constants, se ...

In situ reduction and oxidation of nickel from solid oxide fuel cells in a Titan ETEM

Jan Van Herle, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Antonin Faes

Solid Oxide Fuel Cells (SOFC) common technology is based on anode- supported cells composed of nickel-yttria stabilized zirconia (Ni-YSZ) cermet. The nickel is in oxide state (NiO) during SOFC production and is reduced to metallic nickel during the first o ...

Gold Nanoparticles Supported on Passivated Silica: Access to an Efficient Aerobic Epoxidation Catalyst and the Intrinsic Oxidation Activity of Gold

David Lyndon Emsley, David Benjamin Roger Antoine Gajan

Well-defined and perfectly dispersed [(square SiO)Au(1)] surface species supported on silica have been obtained via surface organometallic chemistry and transformed upon mild reduction (H(2), 300 degrees C) into small (1.8 +/- 0.6 nm) Au particles supporte ...

Electrochemical comparison between IrO2 prepared by anodic oxidation of pure iridium and IrO2 prepared by thermal decomposition of H2IrC16 precursor solution

Christos Comninellis, Olivier Frey, Stéphane Fierro, Lassine Ouattara

Surface redox activities, oxygen evolution reaction (OER), oxidation of formic acid (FA), and anodic stability were investigated and compared for IrO2 electrodes prepared by two techniques: the thermal decomposition of H2IrCl6 precursor (TDIROF) and the an ...

An Iron Carbonyl Pyridonate Complex Related to the Active Site of the [Fe]-Hydrogenase (Hmd)

Rosario Scopelliti, Xile Hu, Blaise Valentin Obrist, Dafa Chen

A mononuclear iron bis(carbonyl) pyridonate complex (1), which exhibits several common structural features with the active site of the iron−sulfur cluster-free [Fe]- hydrogenase, was synthesized and characterized. Spectroscopic data of 1 suggests a 2+ oxid ...
