Chemical Selectivity during the Electro-Oxidation of Ethanol on Unsupported Pt Nanoparticles
(ELECTROCHEMICAL SOC INCPENNINGTON, 2012)
In this paper we present results on the electro-oxidation of ethanol on unsupported (carbon free) platinum nanoparticles, considering the effects of the alcohol concentration. The case of the so-called dual pathway mechanism ...
High Curie point CaBi2Nb2O9 thin films: A potential candidate for lead-free thin-film piezoelectrics
(American Institute of Physics (AIP), 2006-10-01)
CaBi2Nb2O9 (CBNO) thin films deposited on platinum coated silicon substrates by the polymeric precursor method exhibited good structural, dielectric, and piezoelectric characteristics. Capacitance-voltage measurements ...

Quimioterapia para câncer de pulmão de células não pequenas avançado na população idosa: uma revisão sistemática e metanálise
(Universidade Federal de São Paulo (UNIFESP), 2016-08-31)
Background: Approximately 50% of patients with newly diagnosed non-small cell lung cancer (NSCLC) are over 70 years of age at diagnosis. Despite this fact, these patients are underrepresented in randomized controlled trials ...
Altering the adsorptive and electronic properties of Pt through poly(vinyl alcohol) adsorption
(2013-01-22)
In the present paper we investigated the effect of adsorbed PVA on Pt electrodes on classic electrochemical processes such as hydrogen UPD, oxygen reduction and CO electro-oxidation. Upon adsorption PVA blocks roughly 50% ...

Autocatalysis in the open circuit interaction of alcohol molecules with oxidized Pt surfaces
(ROYAL SOC CHEMISTRY, 2008)
We studied the open circuit interaction of methanol and ethanol with oxidized platinum electrodes using in situ infrared spectroscopy. For methanol, it was found that formic acid is the main species formed in the initial ...
