Electrochemical oxidation of ammonia (NH4+/NH3) on thermally and electrochemically prepared IrO2 electrodes

Nico de Rooij, Christos Comninellis, Olivier Frey, Agnieszka Kapalka, Stéphane Fierro, Kai Udert

The electrochemical oxidation of ammonia (NH4+/NH3) in sodium perchlorate was investigated on IrO2 electrodes prepared by two techniques: the thermal decomposition of H2IrCl6 precursor and the anodic oxidation of metallic iridium. The electrochemical behav ...

Selective three-phase hydrogenation of aromatic nitro-compounds over β-molybdenum nitride

Lioubov Kiwi, Fernando Cardenas Lizana, Daniel André Samuel Lamey

A tetragonal molybdenum nitride (β-Mo2N) has been prepared by temperature programmed treatment of MoO3 in flowing N2 + H2 and for the first time shown to catalyze the liquid phase selective hydrogenation (T = 423 K; PH2=11bar) of a series of para-substitut ...

IBX/TBAB-mediated oxidation of primary amines to nitriles

Jieping Zhu

The combination of o-iodoxybenzoic acid (IBX) and tetrabutylammonium bromide (TBAB) efficiently oxidizes primary amines to the corresponding nitriles in good to excellent yield under mild conditions. The reaction is racemization-free when applied to a chir ...

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 ...

The role of copper in cysteine oxidation: study of intra- and inter-molecular reactions in mass spectrometry

Hubert Girault, Michel Prudent

Cysteine-containing peptide oxidation was studied both by using an inert platinum electrode and a sacrificial electrode (copper or zinc) generating metallic ions in electrospray ionization mass spectrometry (ESI-MS). Using peptides containing one, two and ...

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 ...

Transport phenomena in nanofluidics

Reto Bruno Schoch

This thesis explores transport phenomena in nanochannels on a chip. Fundamental nanofluidic ionic studies form the basis for novel separation and preconcentration applications for proteomic purposes. The measurements were performed with 50-nm-high 1D nanoc ...

REVERSE TRANSFER OF NANOSTENCIL PATTERNS USING INTERMEDIATE SACRIFICIAL LAYER AND LIFT-OFF

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Oscar Vazquez Mena

We have developed a new process for reversing the nanostencil patterns by using an intermediate sacrificial layer. Using this process, we can pattern isolated ‘empty’ shapes with their background filled with a certain material, which is impossible with the ...
