A New Environmentally-Friendly Colorimetric Probe for Formaldehyde Gas Detection under Real Conditions

Martínez-Aquino, Carlos; Costero, Ana M.; Gil Grau, Salvador; Gaviña, Pablo (MDPI AG, 2018-10)

[EN] A new environmentally-friendly, simple, selective and sensitive probe for detecting formaldehyde, based on naturally-occurring compounds, through either colorimetric or fluorescence changes, is described. The probe ...
Comparative study of regulated and unregulated gaseous emissions during NEDC in a light-duty diesel engine fuelled with Fischer Tropsch and biodiesel fuels

Bermúdez, Vicente; Luján, José M.; Plá Moreno, Benjamín; Linares Rodríguez, Waldemar Gregorio (Elsevier, 2011-02)

In this study, regulated and unregulated gaseous emissions and fuel consumption with five different fuels were tested in a 4-cylinder, light-duty diesel EURO IV typically used for the automotive vehicles in Europe. Three ...
Effects of low pressure exhaust gas recirculation on regulated and unregulated gaseous emissions during NEDC in a light-duty diesel engine

Bermúdez, Vicente; Luján, José M.; Plá Moreno, Benjamín; Linares Rodríguez, Waldemar Gregorio (Elsevier, 2011-09)

Regulated and unregulated gaseous emissions with high pressure and low pressure EGR (exhaust gas recirculation) system were tested in a 4-cylinder, light-duty diesel EURO IV engine typically used in European vehicles. Four ...

Pérez Borrás, Santiago (Universitat Politècnica de València, 2022-01-12)

[ES] Este trabajo se basa en una revisión bibliográfica que trata de recopilar información acerca de los COV en concreto del formaldehído, el benceno y el tolueno y, cómo estos afectan sobre la salud humana. Se procede a ...
Partial oxidation of methane and methanol on FeOx-, MoOx- and FeMoOx-SiO2 catalysts prepared by sol-gel method: A comparative study

Cortés Ortiz, William G.; Delgado-Muñoz, Daniel; Guerrero Fajardo, Carlos Alberto; Agouram, Said; Sanchís, Ruth; Solsona, Benjamín; López Nieto, José Manuel (Elsevier, 2020-08)

[EN] FeOx-, MoOx and FeMoOx-SiO2 materials prepared by a sol-gel procedure have been evaluated as catalysts for the partial oxidation of methane and methanol. The effect of decreasing the pH of the synthesis gel on the ...
Resorcinol Functionalized Gold Nanoparticles for Formaldehyde Colorimetric Detection

Martínez-Aquino, Carlos; Costero, Ana M.; Gil Grau, Salvador; Gaviña, Pablo (MDPI AG, 2019-02-22)

[EN] Gold nanoparticles functionalized with resorcinol moieties have been prepared and used for detecting formaldehyde both in solution and gas phases. The detection mechanism is based on the color change of the probe upon ...
Structural Study of the Diffusive Flame of Conventional and Synthetic Fuels by Analysis of the Radiation Emitted during the Combustion Process

Tejada Magraner, Francisco José (Universitat Politècnica de València, 2021-10-19)

[ES] La situación social y medioambiental hace que la legislación que regula la emisión de contaminantes sea cada vez más restrictiva, sobre todo en el campo de la automoción, lo que obliga a investigar alternativas al ...
Tungsten-titanium mixed oxide bronzes: Synthesis, characterization and catalytic behavior in methanol transformation

Delgado-Muñoz, Daniel; Soriano Rodríguez, Mª Dolores; Solsona Espriu, Benjamín Eduardo; Zamora Blanco, Segundo; Agouram, Said; Concepción Heydorn, Patricia; López Nieto, José Manuel (Elsevier, 2019-07-25)

[EN] Tungsten oxide bronze-based materials show extremely adaptive structural and compositional features that make them suitable for functional properties modulation. Herein we report the preparation of a series of ...
Vanadium Supported on Alumina and/or Zirconia Catalysts for the Selective Transformation of Ethane and Methanol

Benomar, S.; Masso Ramírez, Amada; Solsona Espriu, Benjamin Eduardo; Isaadi, R.; López Nieto, José Manuel (MDPI AG, 2018-04)

[EN] Vanadium supported on pure (Al2O3, ZrO2) or mixed zirconia-alumina (with Al/(Al + Zr) ratio of 0.75 or 0.25) catalysts have been prepared by wet impregnation, using homemade prepared supports. The catalysts have been ...
Variación del color en las fibras tratadas con ácidos policarboxilicos
