Design and Characterization of Polymeric Materials for their Application as Electrolytes in Fuel Cells

Pascual José, Borja (Universitat Politècnica de València, 2023-09-07)

[ES] Las pilas de combustible de hidrógeno o bioalcohol son una tecnología prometedora para la generación de energía limpia y eficiente en el intento actual de revertir los severos efectos causados por el cambio climático. ...
Hacia una economía circular: revalorización de productos de la semilla de salvia hispanica L. en el sector de los biopolímeros

Domínguez Candela, Iván (Universitat Politècnica de València, 2023-07-17)

[ES] La producción masiva de plásticos ha generado graves problemas medioambientales, ya que su lenta degradación y alta persistencia en el medio ambiente causa la acumulación de residuos plásticos en los océanos y tierras. ...
Preparation and characterisation of new materials for electrolytes used in Direct Methanol Fuel Cells

Martinez Felipe, Alfonso (Universitat Politècnica de València, 2010-05-24)

Summary The aim of this PhD thesis is the preparation and study of new materials to be used as electrolytes in Direct Methanol Fuel Cells (DMFC) in order to reduce crossover of methanol. Different materials have been ...
Reconfigurable Resonator in Decoupled Empty SIW Technology Using Liquid Crystal Material

Sánchez-Marín, Juan Rafael; Bachiller Martin, Maria Carmen; Nova-Giménez, Vicente; Boria Esbert, Vicente Enrique (Institution of Electrical Engineers, 2019-08-08)

[EN] This paper presents a novel continuously tunable microwave resonator based on Liquid Crystal (LC) material. The reconfigurable device is implemented in Decoupled Empty Substrate Integrated Waveguide (DESIW) technology. ...
Synthesis and phase behaviour of a homologous seriesof polymethacrylate-based side-chain liquid crystal polymers

Cook, Andrew G.; Inkster, Rachel T.; Martinez-Felipe, Alfonso; Ribes Greus, María Desamparados; Hamley, Ian W.; Imrie, Corrie T. (Elsevier, 2012)

The homologous series of side chain liquid crystal polymers, the poly[¿-(4-methoxyazobenzene-4¿-oxy)alkyl methacrylate]s, has been prepared in which the length of the flexible alkyl spacer has been varied from 3 to 11 ...
