A contribution to the study of the molecular mobility in polymeric materials by Thermal and Dielectric Analysis

Redondo Foj, María Belén (Universitat Politècnica de València, 2016-01-07)

[EN] The development of new and more complex polymeric materials involves challenging problems to basic sciences. The relationship between structure and molecular dynamics assumes great importance for the future development ...
A novel synthetic approach to tyrosine dimers based on pterin photosensitization

Reid, Lara O.; Castaño, Carolina; Dantola, M L.; Lhiaubet ., Virginie Lyria; Miranda Alonso, Miguel Ángel; Marín García, Mª Luisa; Thomas, A. H. (Elsevier, 2017)

[EN] Oxidative damage to proteins leads to a variety of modifications that are markers of pathogenesis. One of the most important modifications is the dityrosine (Tyr(2)) cross-link, resulting from an oxidative covalent ...
Biochemical Properties of Bioplastics Made from Wheat Gliadins Cross-Linked with Cinnamaldehyde

Pau Balaguer, M.; Gomez-Estaca, Joaquin; Gavara Clemente, Rafael; Hernandez-Munoz, Pilar (American Chemical Society, 2011-12-28)

[EN] The aim of this work has been to study the modification of gliadin films with cinnamaldehyde as a potential crosslinker agent. The molecular weight profile and cross-linking density showed that cinnamaldehyde increased ...
Chemically modified gliadins as sustained release systems for lysozyme

Fajardo, Paula; Balaguer Grimaldo, María de la Paz; Gómez Estaca, Joaquin; Gavara Clemente, Rafael; Hernandez Muñoz, Maria Pilar (Elsevier, 2014-12)

[EN] The aim of this work has been to study the effectiveness of gliadin films cross-linked with cinnamaldehyde as systems for the release of the natural antimicrobial compound lysozyme. Prior to the incorporation of ...
Development of Active Polyvinyl Alcohol/beta-Cyclodextrin Composites To Scavenge Undesirable Food Components

López de Dicastillo Bergamo, Ana Carolina; Jordá, María; Catala Moragrega, Ramón; Gavara Clemente, Rafael; Hernandez-Munoz, Pilar (American Chemical Society, 2011-10-26)

[EN] Active food packaging systems based on the incorporation of agents into polymeric package walls are being designed to purposely release or retain compounds to maintain or even increase food quality. The objective of ...
Effect of carvacrol in the properties of films based on poly (vinyl alcohol) with different molecular characteristics

Andrade, J.; González Martínez, María Consuelo; Chiralt Boix, Mª Amparo (Elsevier, 2020-09)

[EN] Poly (vinyl alcohol) (PVA) is a hydrophilic linear polymer obtained from the controlled hydrolysis of poly (vinyl acetate) (PVAc). The molecular weight (Mw) and degree of hydrolysis (DH) of PVA are considered relevant ...
Effect of neutralization and cross-linking on the thermal degradation of chitosan electrospun membranes

Correia, D. M.; Gamiz Gonzalez, Mª Amparo; Botelho, G.; Vidaurre, Ana; Gómez Ribelles, José Luís; Lanceros-Mendez, S.; Sencadas, V. (Springer-Verlag, 2014-07)

[EN] Thermal degradation of as-electrospun chitosan membranes and samples subsequently treated with ethanol and cross-linked with glutaraldehyde has been studied by thermogravimetry (TG) coupled with an infrared ...
Electrospun adherent-antiadherent bilayered membranes based on cross-linked hyaluronic acid for advanced tissue engineering applications

Arnal Pastor, María Pilar; Martínez Ramos, Cristina; Perez Garnes, Manuel; Monleón Pradas, Manuel; Vallés Lluch, Ana (Elsevier, 2013-10-01)

[EN] A procedure to obtain electrospun mats of hyaluronic acid (HA) stable in aqueous media in one single step has been developed. It consists in combining an HA solution with a divinyl sulfone one as cross-linker in a ...
Estudio de la ultraestructura corneal después del tratamiento con cross-linking

Moreno Pereira, Diego Fernando (Universitat Politècnica de València, 2015-07-01)

[EN] Corneal collagen cross-linking using UVA radiation and riboflavin has been recently developed as a treatment for keratoconus. It was carried out an ultrastructural and comparative analysis of corneas of New Zealand ...
PVA Nanofibers as an Insoluble pH Sensor
