Electrochemical behavior of ammonia at Ni/Ni(OH)2 electrode

Christos Comninellis, Agnieszka Kapalka

The electrochemical oxidation of ammonia was investigated on a Ni/Ni(OH)(2) electrode prepared by potential cycling of a Ni electrode in 1 M NaClO4. It was found that oxidation of ammonia is strongly pH dependent and proceeds mainly at pH values above 7. T ...

Nanoporous YSZ film in electrolyte membrane of Micro-Solid Oxide Fuel Cell

Paul Muralt, Silviu Cosmin Sandu, Yan Yan, Samuel Rey-Mermet

Yttria stabilized zirconia (YSZ) with 8 mol% Y was deposited by reactive magnetron sputtering onto oxidized (100) silicon substrates. It was possible to switch film texture from (111) to (200) by applying a strong RF substrate bias. Transmission electron m ...

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 ...
