Electro-oxidation of ethanol on Pt/C, Rh/C, and Pt/Rh/C-based electrocatalysts investigated by on-line DEMS

Cantane, D. A.; Ambrosio, W. F.; Chatenet, M.; Lima, Fabio Henrique Barros de (ELSEVIER SCIENCE SALAUSANNE, 2013-08-02)

The ethanol electro-oxidation reaction was studied on carbon-supported Pt, Rh, and on Pt overlayers deposited on Rh nanoparticles. The synthesized electrocatalysts were characterized by TEM and XRD. The reaction products ...

Borohydride electrooxidation on Au and Pt electrodes

Lima, Fabio H. B.; Pasqualeti, Anielli M.; Concha, M. Belen Molina; Chatenet, Marian; Ticianelli, Edson A. (PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)

Direct borohydride fuel cells (DBFCs) are attractive energy generators for powering portable electronic devices, mainly due to their high energy density and number of electrons per borohydride ion. However, the lack of a ...

On-line mass spectrometry of the electro-oxidation of methanol in acidic media on tungsten carbide

ANGELUCCI, Camilo A.; DEINER, L. Jay; NART, Francisco C. (SPRINGER, 2008)

The electro-oxidation of methanol at supported tungsten carbide (WC) nanoparticles in sulfuric acid solution was studied using cyclic voltammetry, potentiostatic measurements, and differential electrochemical mass spectroscopy ...

Carbon-dispersed Pt-Rh nanoparticles for ethanol electro-oxidation. Effect of the crystallite size and of temperature

LIMA, F. H. B.; PROFETI, D.; LIZCANO-VALBUENA, W. H.; TICIANELLI, E. A.; GONZALEZ, E. R. (ELSEVIER SCIENCE SA, 2008)

This work presents results of studies of carbon-dispersed Pt-Rh (1:1) nanoparticles as electrocatalysts for the ethanol electro-oxidation. The influences of the crystallite size and the cell temperature on the yields of ...

Studies on obstacle detection and path planning for a quadrotor system

Valencia Mamani, Dalthon Abel (Pontificia Universidad Católica del Perú, 2017)

Implementation of a high performance embedded MPC on FPGA using high-level synthesis

Araujo Barrientos, Antonio (Pontificia Universidad Católica del Perú, 2017)

Determination Of Bismuth In Metallurgical Materials Using A Quartz Tube Atomizer With Tungsten Coil And Flow Injection-hydride-generation Atomic Absorption Spectrometry

Ribeiro A.S.; Arruda M.A.Z.; Cadore S. (, 2002)

Uma voz a serviço do Rio Grande: fragmentos identitários do gaúcho na programação da Rádio Guaiba AM de Porto Alegre

Haussen, Doris Fagundes (Pontifícia Universidade Católica do Rio Grande do SulPorto Alegre, 2008)

The thesis A voice in the service of the Rio Grande: fragments of the gaucho identity in the programming of Radio AM Guaíba of Porto Alegre proposes to respond to three main issues: the Guaíba AM radio is still "a voice ...
