Source identification and airborne chemical characterisation of aerosol pollution from long-range transport over Greenland during POLARCAT summer campaign 2008

We deployed an aerosol mass spectrometer during the POLARCAT (Polar Study using Aircraft, Remote Sensing, Surface Measurements and Models, of Climate, Chemistry, Aerosols, and Transport) summer campaign in Greenland in June/July 2008 on the research aircra ...

Cold Ion Spectroscopy of Biological Molecules in the Gas Phase

Natalia Nagornova

The three-dimensional (3D) structures of proteins and peptides in vivo largely determine their biological functions. In vitro these native structures and their heterogeneity reflect a subtle balance between noncovalent intramolecular interactions and those ...

Sampling and Online Analysis of Alkalis in Thermal Process Gases with a Novel Surface Ionization Detector

Christian Ludwig, Marco Wellinger

When using biomass or waste as a feedstock for power production, alkalis are a major concern because of their negative effects on equipment. To investigate the release behavior of alkalis and the effectiveness of countermeasures, it is indispensable to qua ...

In-cloud oxalate formation in the global troposphere: A 3-D modeling study

Athanasios Nenes

Organic acids attract increasing attention as contributors to atmospheric acidity, secondary organic aerosol mass and aerosol hygroscopicity. Oxalic acid is globally the most abundant dicarboxylic acid, formed via chemical oxidation of gas-phase precursors ...

Films of brookite TiO2 nanorods/nanoparticles deposited by matrix-assisted pulsed laser evaporation as NO2 gas-sensing layers

Raffaella Buonsanti, Mikaël Martino

TiO2 nanorods in the brookite phase, with av. dimensions of 3-4 nm × 20-50 nm, were synthesized by a wet-chem. aminolysis route and used as precursors for thin films that were deposited by the matrix-assisted pulsed laser evapn. (MAPLE) technique. A nanoro ...

Drug delivery of lipophilic pyrenyl derivatives by encapsulation in a water soluble metalla-cage

Paul Joseph Dyson, Olivier Pierre Zava, Anna Katherine Renfrew

The self-assembly of 2,4,6-tris(pyridin-4-yl)-1,3,5-triazine (tpt) triangular panels with p-cymene (p-PriC6H4Me) ruthenium building blocks and 2,5-dioxydo-1,4-benzoquinonato (dobq) bridges, in the presence of a functionalized pyrenyl deriv. (pyrene-R), aff ...

Anticancer activity of opened arene ruthenium metalla-assemblies

Paul Joseph Dyson, Olivier Pierre Zava

Cationic tetranuclear and hexanuclear opened metalla-assemblies incorporating 5,15-bis(4-pyridyl)-10,20-diphenylporphyrin (bpp) or 5,10,15-tris(4-pyridyl)-20-phenylporphyrin (tpp) panels and dinuclear arene ruthenium clips [(p-cymene)2Ru2(OO.intrsec.OO)2]2 ...

Copper(I) and copper(II) binding to β-amyloid 16 (Aβ16) studied by electrospray ionization mass spectrometry

Hubert Girault, Liang Qiao, Michel Prudent, Yu Lu

Copper-b-amyloid 16 (Aβ16) complexes were investigated by electrospray ionization mass spectrometry (ESI-MS). Copper(I) and (II) complexes were formed on-line in a microchip electrospray emitter by using a sacrificial copper electrode as the anode in posit ...

Corona Discharge in Microwave Devices: A Comparison of Ionization Rate Models

Michael Mattes, Francisco Edén Sorolla Rosario

In this paper we compare the predicted Corona breakdown power threshold obtained by different ionization rate models for an infinite parallel-plate waveguide. We point out the lack of a unanimous model of the ionization rate for RF fields and study the dif ...

Electrochemical reactions and ionization processes

Hubert Girault, Niels Erik Lion, Liang Qiao, Michel Prudent, Hongyan Bi, Mélanie Abonnenc

Electrochemical or photo-electrochemical reactions in both electrospray ionization and laser desorption ionization are discussed stressing the role of the electrode reaction in influencing the ionization process. In particular, upon application of a high v ...
