Efecto de la incorporación de ácido p-cumárico en las propiedades de films de PHBV

Vila Montalt, Rubén (Universitat Politècnica de València, 2022-10-20)

[ES] El gran aumento en la producción y consumo de plásticos ha generado un grave problema medioambiental por su incapacidad de biodegradación. Por ello se han puesto en marcha diferentes estrategias como el reciclaje y ...
Influence of homogenization conditions on physical properties and antioxidant activity of fully biodegradable pea protein-alpha-tocopherol films

Fabra, M. José; Jiménez, Alberto; Talens Oliag, Pau; Chiralt, A. (Springer Verlag (Germany), 2014-12)

In this study, antioxidant biodegradable films based on pea protein and alpha-tocopherol were successfully developed by solution casting. The effect of both the homogenization conditions (rotor stator and microfluidizer) ...
Oxygen, water and sodium chloride transport in Soft Contact Lenses Materials

Gavara, Rafael; Compañ Moreno, Vicente (John Wiley & Sons, 2016)

[EN] Oxygen permeability, diffusion coefficient of the sodium ions and water flux and permeability in different conventional hydrogel (Hy) and silicone-hydrogel (Si-Hy) contact lenses have been measured experimentally. The ...
Physical and antioxidant properties of chitosan and methylcellulose based films containing resveratrol

Pastor Navarro, Clara; Sánchez González, Laura; Chiralt, A.; Cháfer Nácher, María Teresa; González Martínez, María Consuelo (Elsevier, 2013)

[EN] New trends in edible films focus on the improvement of their functionality through the incorporation of active compounds, such as antimicrobial or antioxidant agents. Resveratrol is a natural antioxidant found in a ...

[EN] The aim of this experimental work was to study the porous structure of Ultra-High-Performance Fibre-Reinforced Concretes (UH) made with different fibre volume contents (0%, 1%, 2%) under several curing conditions ...
Synthesis and characterization of organic agar-based membranes for microbial fuel cells

Hernández-Flores, Giovanni; Andrio, Andreu; Compañ Moreno, Vicente; Solorza-Feria, Omar; Poggi-Varaldo, Hector Mario (Elsevier, 2019-09-30)

[EN] The goal of this work was the synthesis and characterization of agar membranes for microbial fuel cells applications. Three sets of membranes were synthesized. For a first set of membranes (2, 4, 6, and 8 wt% agar ...
Synthesis and polymerization of acrylic monomers with hydrophilic long side groups. Oxygen transport through water swollen membranes prepared from these polymers

Guzman, J.; Iglesias, M.T.; Riande, E.; Compañ, Vicente; Andrio, Andreu (Elsevier, 1997)

[EN] The synthesis and characterization of tetraethyleneglycol acrylate (TTEGA) and tetraethyleneglycol diacrylate are described. Radical polymerization reactions of TTEGA were carried out at different temperatures and the ...
