Journal ArticleDOI

Oxidation of sodium alginate and characterization of the oxidized derivatives

Cesar Gomez, +3 more
- 01 Feb 2007 - 
TL;DR: In this paper, the effect of degree of oxidation on physical properties of the oxidized derivatives of alginate gels was analyzed and new active functional groups were found on alginates, which is a polymer of interest as support in drug-controlled delivery systems.
Journal ArticleDOI

Thermal and mechanical characterization of linear low‐density polyethylene/wood flour composites

Norma Esther Marcovich, +1 more
- 05 Dec 2003 - 
TL;DR: A linear low-density polyethylene (LLDPE) matrix was modified with an organic peroxide and by a reaction with maleic anhydride (MAn) and was simultaneously compounded with untreated wood flour in a twin-screw extruder.
Journal ArticleDOI

Thermo-compression of biodegradable thermoplastic corn starch films containing chitin and chitosan

Olivia Valeria Lopez, +5 more
- 01 Jun 2014 - 
TL;DR: Lopez et al. as mentioned in this paper presented a study of the relationship between Ingenieria Quimica (IQ) and Criado en Cecnologia de Alimentos (CRIE) in Argentina.
Journal ArticleDOI

Influence of the extraction–purification conditions on final properties of alginates obtained from brown algae (Macrocystis pyrifera)

Cesar Gomez, +4 more
- 01 May 2009 - 
TL;DR: Three methods of sodium alginate extraction-purification from brown seaweeds were used in order to study the influence of process conditions on final properties of the polymer, finding that ethanol route displayed the best performance, where the highest yield and rheological properties were attained with the lowest number of steps.
Journal ArticleDOI

Food packaging bags based on thermoplastic corn starch reinforced with talc nanoparticles

Olivia Valeria Lopez, +4 more
- 01 Jan 2015 - 
TL;DR: In this paper, the authors developed packaging bags from thermoplastic corn starch containing talc nanoparticles (0, 1, 3, 3 and 5% w/w) and evaluated the properties of these bags by tensile tests and quasi-static assays.
