Carboxymethyl Chitosan as a Selective Depressant in Differential Flotation of Galena and Chalcopyrite
DownloadSpring 2015
Toxic inorganic depressants are routinely used in the differential flotation of polymetallic sulfide ores and it is desirable that they be replaced with environmentally benign chemicals. Chitosan, as a natural and non-toxic polymer, has been proven to be an efficient depressant for copper sulfide...

Multifunctional Self-Healing Hydrogels Based on Natural Polymers for Biomedical Applications
DownloadFall 2019
Hydrogel is a chemically or physically cross-linked hydrophilic three-dimensional (3D) polymer network. Classic hydrogels with irreversibly cross-linked polymer networks cannot heal after rupture, leading to degradation and deterioration in their functions over time. In contrast, self-healing...
