[ES] Los procesos convencionales de transformación de materiales requieren afrontar nuevos retos que se presentan en la actual sociedad industrial como es la propia sostenibilidad medioambiental. De la misma forma, los ...
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) ...
Influence of hydroxypropylmethylcellulose addition and homogenization conditions on properties and ageing of corn starch based films

Jiménez Marco, Alberto; Fabra Rovira, María José; Talens Oliag, Pau; Chiralt, A. (Elsevier, 2012-06-20)

[EN] Edible films based on corn starch, hydroxypropyl methylcellulose (HPMC) and their mixtures were prepared by using two different procedures to homogenize the film forming dispersions (rotor-stator and rotor-stator plus ...
Isolation and characterisation of microcrystalline cellulose and cellulose nanocrystals from coffee husk and comparative study with rice husk

Collazo-Bigliardi, Sofía; Ortega-Toro, Rodrigo; Chiralt, A. (Elsevier, 2018)

[EN] Cellulosic material from coffee husk has not been previously studied despite being a potential source of reinforcing agents for different applications. This material has been extracted and characterised from coffee ...
Mechanical properties and moisture-related dimensional change of canvas paintings¿canvas and glue sizing.

Janas, Arkadiusz; Fuster-López, Laura; Andersen, Cecil Krarup; Vicente-Escuder, Ángel; Kozlowski, Roman; Poznanska, Katarzyna; Gajda, Aleksandra; Scharff, Mikkel; Bratasz, Lukasz (BioMed Central, 2022-10-10)

[EN] Understanding canvas paintings as physical systems is fundamental to develop evidence-based environmental specifications for museums. A number of tests were carried out to determine mechanical properties of canvas, ...
