Ru-core Pt-shell nanoparticles show an enhanced electrocatalytic activity for the methanol oxidation reaction (MOR) compared to the respective monometallic or most bimetallic alloy systems. Due to their ill-defined structure, however, a simple interp

Structural modifications during electrochemical measurements on well defined Pt modified Ru(0001) electrode surfaces, which were prepared and characterized under ultrahigh vacuum (UHV) conditions, and the influence of the restructuring on the CO oxid

Sufficient data quality, screening speed and sample throughput are often discussed as the three controversial factors in primary screening attempts within HTE (high throughput experimentation). Hence, one of the most exciting challenges for stage-I-s

In 2-mm microreactors the activity and selectivity of catalyst library components can be monitored directly by robot-controlled mass spectrometry (the principle setup is shown in the scheme). A maximum of 60 seconds per library component are required

Mixtures of tri-n-butyltin thiolates, -alcoholates and -carboxylates were investigated. A characterization of diastereomeric compounds using their 119Sn-NMR-spectra was of special interest. It is shown that 119Sn-NMR spectroscopy is a useful method f

We have studied the potential of saturation transfer nuclear magnetic resonance (NMR) experiments in different mode to screen compound mixtures for binding activity and to characterize binding epitopes on the ligand. We have developed a protocol base

A method is described for the NMR determination of the enantiomeric composition of chiral carboxylic acids and alcohols using their triphenyltin derivatives together with the chiral solvating agents quinine hydrochloride and phenylethylamine.
