A New Use of Polysorbate-Type Nonionic Surfactants as Plasticizers for Highly Flexible Poly(lactide) Formulations

Gázquez-Navarro, José Javier; Garcia-Sanoguera, David; Balart, Rafael; Garcia-Garcia, Daniel; Gómez-Caturla, Jaume (Springer-Verlag, 2024-09)

[EN] Polysorbates are non-ionic amphiphilic organic compounds, widely used as surfactants. They have a molecular weight in the 1200-1400 g mol-1 range, so they are on the borderline between monomeric and polymeric plasticizers. ...
Desarrollo del proceso de extracción del almidón de residuos de patata y caracterización del mismo con el fin de validar su utilización para la elaboración de películas de bioplástico

Barandiaran Torres, Alejandro (Universitat Politècnica de València, 2022-10-31)

[ES] La búsqueda y obtención de materiales de origen natural y biodegradables realmente útiles, capaces de reemplazar por completo a los tradicionales de origen petroquímico, se ha convertido en un tema en auge. Para ...
Glass transition and dynamics in BSA-water mixtures over wide ranges of composition studied by thermal and dielectric techniques

Panagopoulou, A.; Kyritsis, A.; Sabater i Serra, Roser; Gómez Ribelles, José Luís; Shinyashiki, N.; Pissis, P. (Elsevier, 2011)

Protein-water dynamics in mixtures of water and a globular protein, bovine serum albumin (BSA), was studied over wide ranges of composition, in the form of solutions or hydrated solid pellets, by differential scanning ...
Glass transition and dynamics in lysozyme-water mixtures over wide ranges of composition

Panagopoulou, Anna; Kyritsis, Apostolos; Aravantinou, Anna-Maria; Nanopoulos, Dionysios; Sabater i Serra, Roser; Gómez Ribelles, José Luís; Shinyashiki, Naoki; Pissis, Polycarpos (Springer Verlag (Germany), 2011-06)

[EN] Differential scanning calorimetry (DSC) and two dielectric techniques, broadband dielectric relaxation spectroscopy and thermally stimulated depolarization currents (TSDC), were employed to study glass transition and ...
Innovative solutions and challenges to increase the use of poly(3-hydroxybutyrate) in food packaging and disposables

Garcia-Garcia, Daniel; Quiles-Carrillo, Luis; Balart, Rafael; Torres-Giner, S.; Arrieta, Marina P. (Elsevier, 2022-09-05)

[EN] Poly(3-hydroxybutyrate) (PHB) has gain in recent years a huge interest in the food packaging field due to its renewable origin from waste as well as non-food crops, high mechanical strength, medium-to-high barrier ...
Plasticization effects of epoxidized vegetable oils on mechanical properties of poly(3-hydroxybutyrate)

García García, Daniel; Ferri Azor, José Miguel; Montañés Muñoz, Néstor; López-Martínez, Juan; Balart Gimeno, Rafael Antonio (Wiley, 2016-10)

The effect of various epoxidized vegetable oils as potential plasticizers for poly(3-hydroxybutyrate) (PHB) was evaluated in terms of changes in mechanical and thermal properties and morphology. PHB is a biodegradable ...
Polymer segmental dynamics and solvent thermal transitions in Poly(ethyl acrylate)/p-xylene mixtures

Stathopoulos, A.T.; Kyritsis, A.; Romero Colomer, Francisco José; Gómez Ribelles, José Luís; Shinyashiki, N.; Christodoulides, C.; Pissis, P. (Wiley-Blackwell, 2011-03)

A poly(ethyl acrylate) polymer network was swollen with different concentrations of the nonpolar solvent p-xylene, cpx, from xerogel until saturation (0 cpx 0.85). Differential scanning calorimetry (DSC) and thermally ...
Procesado y caracterización de plásticos industriales de polímeros con plastificantes derivados de ésteres del ácido cinámico

Barandiaran Torres, Alejandro (Universitat Politècnica de València, 2024-09-02)

[ES] El objetivo principal de la presente tesis doctoral es el estudio y desarrollo de materiales basados en el ácido poliláctico (PLA) y policloruro de vinilo (PVC) con el fin de mejorar las propiedades y poder ...
The Schroeder paradox or how the state of water affects the moisture transfer through edible films

Hambleton, Alicia; Perpinan-Saiz, N.; Fabra Rovira, María José; Voilley, A.; Debeaufort, F. (Elsevier, 2012-06-15)

The objective of this work was to better understand the water permeation through edible films when water is either in its vapour or in its liquid state related to their physico-chemical properties. Film based on iota-carrageenans ...
