New Metabolites in the Degradation of α- and γ-Hexachlorocyclohexane (HCH): Pentachlorocyclohexenes Are Hydroxylated to Cyclohexenols and Cyclohexenediols by the Haloalkane Dehalogenase LinB from Sphingobium indicum B90A

Christof Holliger, Thomas Geiger, Vishakha Raina

Technical hexachlorocyclohexane (HCH) and lindane are obsolete pesticides whose former production and use led to widespread contaminations posing serious and lasting health and environmental risks. Out of nine possible stereoisomers, α-, β-, γ-, and δ-HCH ...

Studies on the reactivity of organometallic Ru-, Rh- and Os-pta complexes with DNA model compounds

Paul Joseph Dyson, Rosario Scopelliti, Christian Hartinger, Antoine Dorcier

The reactions of arene-metal complexes (arene = p-cymene, benzene or pentamethylcyclopentadienyl, metal = Ru, Rh or Os), including 1,3,5-triaza-7-phosphatricyclo-[3.3.1.1]decanephosphine (pta) and chloro co-ligands, with 9-methylguanine, adenine, and a ser ...

High Resolution Mass Spectrometry for Studying the Interactions of Cisplatin with Oligonucleotides

Paul Joseph Dyson, Yury Tsybin, Christian Hartinger, Hisham Ben Hamidane

Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has been used to probe the interaction of the anticancer drug cisplatin with oligonucleotides. The binding kinetics, the nature of the adducts formed, and the location of the binding s ...

Three-Phase Catalytic Hydrogenation of a Functionalized Alkyne: Mass Transfer and Kinetic Studies with in Situ Hydrogen Monitoring

Albert Renken, Lioubov Kiwi, Martin Grasemann

Systematic studies of mass transfer interactions with intrinsic reaction kinetics were performed for the threephase selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) over a modified Pd/CaC

Electronic and vibrational spectroscopy of cold protonated amino acids in the gas phase

Sébastien Mercier

In this thesis report, we describe a novel home-built instrument designed to study the spectroscopy of biomolecular ions in the gas phase and at low temperature, and we present the first experimental results obtained on protonated aromatic amino acids. The ...

Electron-phonon interaction and charge carrier mass enhancement in SrTiO3

Claudio Grimaldi, Dirk Van der Marel

We report a comprehensive THz, infrared and optical study of Nb-doped SrTiO3 as well as dc conductivity and Hall effect measurements. Our THz spectra at 7 K show the presence of an unusually narrow (< 2 meV) Drude peak. For all carrier concentrations the D ...

Magnetic circular dichroism in electron energy loss spectrometry

Cécile Hébert

The measurement of circular dichroism in the electron microscope is a new, emerging method and, as such, it is subject to constant refinement and improvement. Different ways can be envisaged to record the signal. We present an overview of the key steps in ...

Neutral hydrogen in the local universe

Danail Obreschkow

We revisit the composition of neutral hydrogen, i.e. atomic (HI) and molecular (H2), in the local Universe, with focus on the H2-to-HI mass ratio R in various galaxies and the H2-mass function (MF). First, we derive the H2-MF from the CO-luminosity functio ...

Electrochemical generation of Cu(I) complexes in aqueous solutions studied by on-line mass spectrometry

Hubert Girault, Christophe Roussel, Michel Prudent

Taking advantage of the electrochemical aspects of electrospray ionization (ESI) sources in positive ionization mode mass spectrometry (MS), aqueous copper complexes are electrogenerated using sacrificial copper electrodes. When using 8-hydroxyquinoline or ...
