Polyelectrolyte Complexation versus Ionotropic Gelation for Chitosan-Based Hydrogels with Carboxymethylcellulose, Carboxymethyl Starch, and Alginic Acid
Autor: Elizabeth Henao, Ezequiel Delgado, Héctor Contreras, Germán Quintana
Publikováno v: International Journal of Chemical Engineering, Vol 2018 (2018)
The preparation of gels by charge interaction methods has been extensively studied, but it is not yet clear how these methods influence gel characteristics. The objective of this work was to study differences in morphology and surface charge of hydro

Rheological behavior of magnetic pulp fiber suspensions
Autor: Jorge H. Sánchez, Germán Quintana, Xiomara Pineda, Adriana P. Herrera
Publikováno v: June 2021. 20:393-403
This paper is focused on the rheology of magnetic pulp suspensions in absence and presence of an external magnetic field. Magnetic fibers were prepared by the lumen loading method using bleached eucalyptus fibers and cobalt ferrite (CoFe2O4) nanopart
