Aplicación de la espectroscopia infrarroja en la diferenciación de mieles según origen geográfico

Segura Melchor, Clara (Universitat Politècnica de València, 2023-10-16)

[ES] El desarrollo de herramientas analíticas sencillas que permitan autentificar el origen geográfico de las mieles, actualmente, es una necesidad para el sector agroalimentario. En concreto, para las mieles españolas, ...
Bio-Photonic Sensing Cells over transparent substrates for anti-gestrinone antibodies biosensing

Sanza, F.J.; Holgado, M.; Ortega Higueruelo, Francisco José; Casquel Del Campo, Rafael; López-Romero, D.; Bañuls Polo, Mª José; Laguna, Mari Fe; Barrios, C.A.; Puchades Pla, Rosa; Maquieira Catala, Ángel (Elsevier, 2011)

[EN] In a previous work we introduced the term Bio-Photonic Sensing Cells (BICELLs), referred to periodic networks of nano-pillar suitable for biosensing when are vertically interrogated. In this article, we demonstrate ...
Chemometric compositional analysis of phenolic compounds in fermenting samples and wines using different infrared spectyroscopy techniques

Aleixandre-Tudó, José Luis; Nieuwoudt, Helené; Aleixandre Benavent, José Luís; Du toit, Wessel (Elsevier, 2017)

[EN] The wine industry requires reliable methods for the quantification of phenolic compounds during the winemaking process. Infrared spectroscopy appears as a suitable technique for process control and monitoring. The ...
Estudio del pH y la conductividad eléctrica (CE) de películas pictóricas de malaquita en el contexto de su intervención con métodos acuosos.

García Ibáñez, Marian (Universitat Politècnica de València, 2021-01-28)

[ES] Tal y como la literatura científica viene demostrando, la composición y propiedades que adquiere una película pictórica durante su secado y envejecimiento está determinada no solo por las condiciones medioambientales ...
Infrared spectroscopy and chemometric applications for the qualitative and quantitastive investigation of grapevine organs.

Wyngaard, Elizma van; Blancquaert, Erna; Nieuwouldt, Helene; Aleixandre Tudo, José (Frontiers Media SA, 2021-09-03)

[EN] The fourth agricultural revolution is leading us into a time of using data science as a tool to implement precision viticulture. Infrared spectroscopy provides the means for rapid and large-scale data collection to ...
Modification of surface wettability of sodium ionomer sheets via atmospheric plasma treatment

España Giner, José Manuel; García Sanoguera, David; Sánchez Nacher, Lourdes; López Martínez, Juan; Balart Gimeno, Rafael Antonio (Wiley-Blackwell, 2012-12)

[EN] In this study, atmospheric plasma treatment has been used to modify the wetting properties of ethylene-methacrylic acid sodium ionomer. The effects of the plasma treatment on surface properties of this ionomer have ...
Oxidation mechanism of formic acid on the bismuth adatom-modified Pt(111) surface

Perales Rondón, Juan Victor; Ferre Vilaplana, Adolfo; Feliu, Juan; Herrero, Enrique (American Chemical Society, 2014-09-14)

In order to improve catalytic processes, elucidation of reaction mechanisms is essential. Here, supported by a combination of experimental and computational results, the oxidation mechanism of formic acid on Pt(111) ...
Photopolymerization as a promising method to sense biorecognition events

Peris Chanzá, Ernesto José; Bañuls Polo, María-José; Maquieira Catala, Ángel; Puchades, Rosa (Elsevier, 2012-12)

[EN] This work addresses the main topics related to the photopolymerization process to develop and to monitor the analytical signal derived from biorecognition assays. We review basic aspects of photopolymerization, together ...
Spectroscopic and thermal characterisation of the swelling behaviour of nafion membranes in mixtures of water and methanol

Martinez-Felipe, Alfonso; Imrie, Corrie Thomas; Ribes Greus, María Desamparados (Wiley, 2013-01-05)

The spectroscopic and thermal properties of swollen Nafion membranes in methanol aqueous mixtures were investigated to understand the behavior of commercial electrolytes in the presence of polar solvents. Several differences ...
Surface modification of polypropylene substrates by UV photografting of methyl methacrylate (MMA) for improved surface wettability

Balart Gimeno, Javier Francisco; Fombuena Borrás, Vicent; Boronat Vitoria, Teodomiro; Reig Pérez, Miguel Jorge; Balart Gimeno, Rafael Antonio (Springer Verlag (Germany), 2012-03)

Despite polypropylene is one of the most used commodity plastics, its adhesion properties are remarkably restricted by its non-polar nature which leads to low wetting properties and, consequently, poor adhesion behavior. ...
Variety Discrimination of Fruits, Edible Plants, and Other Foodstuffs and Beverages by Infrared Spectroscopy

Lerma-García, María Jesús; Cortes-Lopez, Victoria; Talens Oliag, Pau; Barat Baviera, José Manuel (Elsevier, 2018)

[EN] Infrared (IR) spectroscopy followed by the employment of multivariate chemometric techniques has been widely used for foodstuffs and beverage authenticity and traceability. Among the different IR applications, variety ...
