Characterization of Crosslinked Poly(vinyl alcohol)-Based Membranes with Different Hydrolysis Degrees for Their Use as Electrolytes in Direct Methanol Fuel Cells

Martinez-Felipe, Alfonso; Moliner Estopiñán, Cristina Elia; Imrie, Corrie Thomas; Ribes Greus, María Desamparados (Wiley, 2012-04-15)

The effect of the degree of hydrolysis of poly(vinyl alcohol) (PVA) substrates on the preparation and properties of crosslinked membranes prepared via esterification with sulfosuccinic acid (SSA) has been studied using ...
Design of enzyme-mediated controlled release systems based on silica mesoporous supports capped with ester-glycol groups

Agostini, Alessandro; Mondragón Martínez, Laura; Pascual Vidal, Lluís; Aznar Gimeno, Elena; Coll Merino, Mª Carmen; Martínez Mañez, Ramón; Sancenón Galarza, Félix; Soto Camino, Juan; Marcos Martínez, María Dolores; Amoros del Toro, Pedro; Costero, Ana M.; Parra, Margarita; Gil, Salvador (American Chemical Society, 2012-09-21)

[EN] An ethylene glycol-capped hybrid material for the controlled release of molecules in the presence of esterase enzyme has been prepared. The final organic-inorganic hybrid solid S1 was synthesized by a two-step procedure. ...
Esterificación de ácidos grasos en lecho fijo

Martínez Castelló, Aarón (Universitat Politècnica de València, 2023-01-20)

[ES] En la presente tesis doctoral el principal objetivo ha sido desarrollar una nueva metodología para producir monoésteres, diésteres y polioles derivados de ácidos grasos de forma continua. Una producción en continuo ...
Preparation of Glycerol Carbonate Esters by using Hybrid Nafion-Silica Catalyst

Climent Olmedo, María José; Corma Canós, Avelino; Iborra Chornet, Sara; Martínez Silvestre, Sergio; Velty ., Alexandra (Wiley-VCH Verlag, 2013-07)

Glycerol carbonate esters (GCEs), which are valuable biomass-deriv. compds., have been prepd. through the direct esterification of glycerol carbonate and long org. acids with different chain lengths, in the absence of ...
Solid-catalyzed esterification reaction of long-chain acids and alcohols in fixed-bed reactors at pilot plant scale

Martínez-Castelló, Aaron; Tejeda-Serrano, Maria; Nowacka, Anna Elzbieta; Oliver-Meseguer, Judit; Leyva Perez, Antonio (Elsevier, 2022-08)

[EN] The esterification reaction of long-chain acids and alcohols is carried out in both academia and industry with soluble strong acids such as phosphoric or methanesulfonic acid, since the lower diffusion and higher ...
Tailoring structural, rheological and gelling properties of watermelon rind pectin by enzymatic treatments

Mendez-Reyes, Daniel Alexander; Martínez-Abad, Antonio; Martínez-Sanz, Marta; López-Rubio, A.; Fabra Rovira, Maria José (Elsevier, 2022-08)

[EN] In this work, pectin extracts from watermelon rind (WRP) were enzymatically treated to evaluate their potential for preparing hydrogels with the addition of CaCl2. Based on a previous work, two different conditions ...
