Structure and Mechanism of the Influenza A M2(18-60) Dimer of Dimers

We report a magic angle spinning (MAS) NMR structure of the drug-resistant S31N mutation of M2(18-60) from Influenza A. The protein was dispersed in diphytanoyl-sn-glycero-3-phosphocholine lipid bilayers, and the spectra and an extensive set of constraints ...

Atomic Oxygen Chemisorption on Carbon Nanotubes Revisited with Theory and Experiment

Wanda Andreoni, Fabio Pietrucci, Alessandro Curioni

Density-functional-theory based calculations of two single-walled carbon nanotubes of different chirality settle open issues on the sidewall chemisorption of atomic oxygen at low concentrations. Ether groups are the thermodynamically favored configurations ...

Multifaceted Chemistry of [(Cymene)RuCl2]2 and PCy3

Rosario Scopelliti, Kay Severin, Euro Solari, Sébastien Gauthier

The reaction of (cymene)RuCl2 (1) with PCY3 was investigated using different stoichiometries and reaction conditions. Whereas a mixture of complex 1 and 2 equiv of PCy3 in methanol gave the known adduct [(cymene)Rucl(2)(PCy3)] (3) along with the phosp ...

Mechanisms of Phenol Ozonation-Kinetics of Formation of Primary and Secondary Reaction Products

Urs von Gunten

Organic acids are part of assimilable organic carbon (AOC) formed from natural organic matter (NOM) during ozonation for drinking water production. To elucidate the formation of organic acids, phenol as surrogate compound for NOM was ozonated while suppres ...

Methyl tertiary hexyl ether and methyl tertiary octyl ether as gasoline oxygenates : Assessing risks from atmospheric dispersion and deposition

Jeremy Samuel Arey

Methyl tertiary hexyl ether (MtHxE) and methyl tertiary octyl ether (MtOcE) are currently being developed as replacement oxygenates for methyl tertiary butyl ether (MtBE) in gasoline. As was the case with MtBE, the introduction of these ethers into fuel su ...

Measurement and modelling of semi-batch reactions using small-scale reaction calorimetry, in-situ spectroscopy and gas consumption/production

Julien Léo Billeter, Konrad Hungerbühler

The rapid and complete characterization of chemical reaction mechanisms is of the utmost importance in terms of chemical understanding, safety and efficiency. In this presentation a new small volume reaction calorimeter (25-45mL) is described. With this re ...

A physical-chemical screening model for anticipating widespread contamination of community supply wells by gasoline constituents

Jeremy Samuel Arey

Continuing modifications of fuels like gasoline should include evaluations of the proposed constituents for their potential to damage environmental resources such as subsurface water supplies. Consequently, we developed a screening model to estimate well w ...
