Fingerprinting the reactive toxicity pathways of 50 drinking water disinfection by-products

Urs von Gunten

A set of nine in vitro cellular bioassays indicative of different stages of the cellular toxicity pathway was applied to 50 disinfection by-products (DBPs) to obtain a better understanding of the commonalities and differences in the molecular mechanisms of ...

Electrochemical oxygen reduction at soft interfaces catalyzed by the transfer of hydrated lithium cations

Hubert Girault, Pekka Eero Peljo, Thomas James Stockmann, Haiqiang Deng

The oxygen reduction reaction by decamethylferrocene (DMFc), triggered by hydrophilic metallic cations behaving as Lewis acids towards water molecules in a homogeneous organic phase reaction, was investigated using cyclic voltammetry at the water|1,2-dichl ...

Striking Influence of the Catalyst Support and Its Acid–Base Properties: New Insight into the Growth Mechanism of Carbon Nanotubes

Arnaud Magrez, Gabor Laurenczy, Endre Horvath, Jin Won Seo, Rita Smajda, Donatello Acquaviva, Juan Carlos Andresen

In the accepted mechanisms of carbon nanotube (CNT) growth by catalytic chemical vapor deposition (CCVD), the catalyst support is falsely considered as a passive material whose only role is to prevent catalytic particles from coarsening. The chemical chang ...

Water-soluble arene ruthenium complexes containing pyridinethiolato ligands: Synthesis, molecular structure, redox properties and anticancer activity of the cations [(η6-arene)Ru(p-SC5H4NH)3]2+

Paul Joseph Dyson, Anna Katherine Renfrew

The cationic complexes [(η6-arene)Ru(SC5H4NH)3]2+, arene being C6H6 (1), MeC6H5 (2), p-iPrC6H4Me (3) or C6Me6 (4), have been synthesized from the reaction of 4-pyridinethiol with the corresponding precursor (η6-arene)2Ru2(μ2-Cl)2Cl2 and isolated as the chl ...

Salts of electrophilic cations and Lewis acid-base adducts with weakly coordinating anions : synthesis, characterization and quantum chemical calculations

Ines Raabe

During the last decades, weakly coordinating anions (WCAs) have become a field of great interest both in basic and applied chemistry, as – if compared to "normal" classical anions like Cl- or SO42- – they have a lot of unique and unusual properties, such a ...

Reactivity of manganese, technetium and rhenium aquacarbonyl-complexes as potential precursors for radiopharmaceuticals

Pascal Grundler

Technetium is an artificial element and its isotope 99mTc is now used for several years as radio-imaging agent. Much research effort is directed towards enhanced targeting of the imaging agents in order to improve accuracy of the diagnosis and reduce the r ...
