Fabrication of metallic nanoparticles by electrochemical discharges

Hannes Bleuler, Ashwin Lal

A method for the fabrication of metallic nanoparticles in large quantities by electrochemical discharges is presented. In an aqueous electrolyte, large current density (similar to 1 A/mm(2) at similar to 20 V) leads to the formation of a 'gas film' around ...

On-line Electrogeneration of Copper-Peptide Complexes in Microspray Mass Spectrometry

Hubert Girault, Michel Prudent

The interaction of copper ions with peptides was investigated by electrospray mass spectrometry. Two electrospray micro-emitters were compared, the first one with a platinum electrode using a copper(II) electrolyte solution containing a peptide sample, and ...
