Numerical modeling of the cooking extrusion of a bio-polymer
Cooking extrusion is becoming an essential processing step in a number of food processes. Modeling of extruder performance is the first step towards the ultimate goal of prediction of product properties and quality based on governing extruder characteristics and operation. The purpose of this study …

Physical and mechanical behaviors of pineapple leaf fibre reinforced thermoplastics corn starch bio polymer composites
… is growing due to the accumulating of non-biodegradable waste, mainly the disposable product. Starch is one of the potential materials due to the easy availability, low cost, renewability and biodegradability. However, the natural behaviours associated with corn starch (CS) have …

Development of Sustainable Masonry Brick
… explores the potential of incorporating HBS-polymer which is a biologically-inert product produced after various treatment processes in the Environmental Laboratory of Lassonde, and Incinerated Sewage Sludge Ash (ISSA) obtained from biological treatment facilities as alternative raw materials …

Advancing wastewater valorization using anaerobic membrane bioreactors with bioaugmentation and ion-exchange, and bio-plastic production
… recovery in a novel two-phase anaerobic membrane bioreactor (AnMBR) process incorporating bioaugmentation and ion-exchange resins, as well as bio-polymer recovery via mixed microbial culture (MMC) polyhydroxyalkanoate (PHA) production. The first study presented in this dissertation investigated …

Design tools and predictions for nonlinear elastic solids in soft machine design
… We find that these predictions align with bio-polymer networks and semi-flexible fibers that also shear soften in compression. However, these models do not capture the behavior of biological tissues that shear stiffen in compression. We provide insight to the constitutive model predictions …

Electro-mechanically interfacing with biology using piezoelectric polymer nanostructures
Biological cells are naturally exposed to a wealth of stimuli that influence their function and behaviour. In fields where the focus is on artificially growing biological material, such as tissue engineering and regenerative medicine, it is important to consider this array of senses to ensure …

Microstructural and fluid transport properties of potatoes during frying
Microstructural and transport properties are the key determinants to understand the product quality, oil uptake and moisture loss during frying of foods. Besides, permeability is also an important physical property for studying the transport mechanisms of porous foods when pressure driven flow is …

Polymers and colloids in flows : from dynamics to self-healing
Polymers and colloids are important building blocks of life as well as many modern technologies. Driven by ow, polymers and colloids can express very complex yet interesting behavior. This thesis aims at a fundamental understanding of the dynamical properties of dierent polymer-colloid mixtures in …

Processing Extrudable Sheets using Decoloured Bloodmeal
… poly (lactic acid) (PLA), a semi-crystalline polymer, and subsequently processing the blend into a sheet using extrusion. Free radical grafting was used to graft itaconic anhydride onto PLA to create reactive side groups. Blends of DBT and PLA compatibilized with itaconic anhydride were …
