A method of pulse array design for voltammetric electronic tongues

Campos Sánchez, Inmaculada; Alcañiz Fillol, Miguel; Masot Peris, Rafael; Soto Camino, Juan; Martínez Mañez, Ramón; Vivancos, José-Luís; Gil Sánchez, Luís (Elsevier, 2012-01-03)

This paper proposes a reasonable methodology for the design of pulse arrays applied in classification and quantification techniques based on the use of pulse voltammetric electronic tongues. As model problem we designed a ...
An optoelectronic sensing device for CO detection in air based on a binuclear rhodium complex

Moragues Pons, María Esperanza; Montes Robles, Roberto; Ros-Lis, José Vicente; Alcañiz Fillol, Miguel; Ibáñez Civera, Francisco Javier; Pardo Vicente, María Teresa; Martínez Mañez, Ramón (Elsevier, 2014-02)

The design, fabrication and validation of an optoelectronic sensor implemented in an easy-to-use portable device for the selective and sensitive detection of CO in air is reported herein. The system is based on the colour ...
Catalizadores heterogéneos de rodio y cobalto para la hidroformilación de olefinas y la reacción de evolución del hidrógeno

Galdeano Ruano, Carmen Piedad (Universitat Politècnica de València, 2024-03-10)

[ES] La presente tesis doctoral se centra en la investigación y desarrollo de catalizadores avanzados con aplicaciones en la industria química. Desde la síntesis de nanopartículas de Rh2P hasta la exploración de catalizadores ...
Design of an electronic system and its application to electronic tongues using variable amplitude pulse voltammetry and impedance spectroscopy

Alcañiz Fillol, Miguel; Vivancos, José-Luís; Masot Peris, Rafael; Ibáñez Civera, Francisco Javier; Raga Ramón, María; Soto Camino, Juan; Martínez Mañez, Ramón (Elsevier, 2012-07)

Electronic equipment (IDM-1) especially designed for the application of voltammetric and impedometric electronic tongues is described. For impedance spectroscopy the equipment permits the generation of sinusoidal signals ...
New insights into the role of the electronic properties of oxide promoters in Rh-catalyzed selective synthesis of oxygenates from synthesis gas

Prieto González, Gonzalo; Concepción Heydorn, Patricia; Martinez Feliu, Agustin; Mendoza, Ernest (Elsevier, 2011-06-13)

[EN] A series of 2.5% Rh/M@Al2O3 model catalysts were prepared by supporting Rh on high-area gamma-Al2O3, resulting in a surface covered by a monolayer (4.5-7 atoms/nm(2)) of MO promoter oxides (M = Fe, V. Nb, Ta, Ti, Y, ...
Selective hydrogenation of 1,3-butadiene and 1-butyne over a Rh/chitosan catalyst investigated by using parahydrogen-induced polarization

Barskiy, Danila A; Kovtunov, Kirill V.; Primo Arnau, Ana María; Corma Canós, Avelino; Kaptein, Robert; Koptyug, Igor V (Wiley-VCH Verlag, 2012-12)

[EN] Hydrogenation of 1,3-butadiene and 1-butyne over the Rh/chitosan catalyst in gaseous and liquid phases was investigated by using the NMR and parahydrogen-induced polarization technique. The Rh/chitosan system was a ...
Sensitive and selective chromogenic sensing of carbon monoxide via reversible axial CO coordination in binuclear rhodium complexes

Moragues Pons, María Esperanza; Esteban Moreno, Julio; Ros-Lis, José Vicente; Martínez Mañez, Ramón; Marcos Martínez, María Dolores; Martínez, Manuel; Soto Camino, Juan; Sancenón Galarza, Félix (American Chemical Society, 2011-10)

The study of probes for CO sensing of a family of binuclear rhodium(II) compounds of general formula [Rh 2{(XC 6H 3)P(XC 6H 4)} n(O 2CR) 4-n]·L 2 containing one or two metalated phosphines (in a head-to-tail arrangement) ...
Surface-Mediated Synthesis of Dimeric Rhodium Catalysts on MgO: Tracking Changes in the Nuclearity and Ligand Environment of the Catalytically Active Sites by X-ray Absorption and Infrared Spectroscopies

Yardimci, Dicle; Serna Merino, Pedro Manuel; Gates, Bruce C. (Wiley, 2013-01)

[EN] The preparation of dinuclear rhodium clusters and their use as catalysts is challenging because these clusters are unstable, evolving readily into species with higher nuclearities. We now present a novel synthetic ...
TNT detection using a voltammetric electronic tongue based on neural networks

García Breijo, Eduardo; Olguín Pinatti, Cristian Ariel; Masot Peris, Rafael; Alcañiz Fillol, Miguel; Martínez Mañez, Ramón; Soto Camino, Juan (Elsevier, 2013-04-01)

We report here the use of a voltammetric electronic tongue based on simple metallic electrodes for the detection and discrimination of different concentrations of 2, 4, 6-trinitrotoluene (TNT) in acetonitrile: water 1:1 ...
