Research paper thumbnail of Direct magnetic resonance detection of neuronal electrical activity

Proceedings of The National Academy of Sciences, 2006

Research paper thumbnail of The performance of Pt nanoparticles supported on Sb 2O 5.SnO 2, on carbon and on physical mixtures of Sb 2O 5.SnO 2 and carbon for ethanol electro-oxidation

International Journal of Hydrogen Energy, 2010

Pt nanoparticles were supported on Sb2O5.SnO2 (ATO), on carbon and on physical mixtures of ATO an... more Pt nanoparticles were supported on Sb2O5.SnO2 (ATO), on carbon and on physical mixtures of ATO and carbon by an alcohol-reduction process using ethylene glycol as reducing agent. The obtained materials were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Their performance for ethanol oxidation was investigated at room temperature by chronoamperometry and in a direct ethanol fuel cell (DEFC) at 100 °C. Pt nanoparticles supported on a physical mixture of ATO and carbon showed a significant increase of performance for ethanol oxidation compared to Pt nanoparticles supported on ATO or on carbon.
