Edible Films from Starch and Chitosan: Formulation and Gas Permeabilities
(University of Waterloo, 2008-12-12)Starch and chitosan films are both known to be effective barriers to gas permeation. Being naturally abundant, renewable, and biodegradable, starch and chitosan films have the potential to replace petroleum-based materials ... -
In-plane and through-plane gas permeability of carbon fiber electrode backing layers
(Elsevier, 2006-11-08)The absolute gas permeability of several common gas diffusion layer (GDL) materials for polymer electrolyte membrane fuel cells was measured. Measurements were made in three perpendicular directions to investigate anisotropic ... -
Potential Applications of Silk Fibroin as a Biomaterial
(University of Waterloo, 2013-06-19)Fibroin is a biopolymer obtained from the cocoons of the Bombyx mori silkworm that offers many unique advantages. In this thesis work, fibroin was processed into a regenerated film and examined for potential biomaterial ... -
Serial Compression Effects on Porosity, Diffusion, Permeability, and Water Droplet Contact Angle of the Gas Diffusion Layer in Polymer Electrolyte Membrane Fuel Cells
(University of Waterloo, 2020-05-14)The polymer electrolyte membrane (PEM) fuel cell is an electrochemical device that directly converts the chemical energy of hydrogen and oxygen into electricity with water and heat as byproducts. It is very promising to ... -
A Study of the Mobility of Silver Ions in Chitosan Membranes
(University of Waterloo, 2007-06-14)Chitosan membrane has found applications in biomedical, wastewater treatment, and petrochemical fields that involve the use of silver ions (Ag+). However, mobility of Ag+ in chitosan membranes has seldom been studied. ...
