Use of poly vinyl alcohol (PVA) cryogelation for tissue engineering: composites, scaffold formation and cell encapsulation
PVA cryogelation is a physical hydrogel formation method, which yields cryogels with comparable mechanical properties to vascular tissue. However PVA cryogels are not suitable for cell attachment and proliferation alone. This can be overcome by the development of composite cryogels. Moreover, …

Inexpensive, energy-efficient, grid-independent storage and cooling system for the Developing World
… Using Polyurethane structure insulated panels, Cryogel ice balls, and a unique storage layout, the team was able to design a prototype that met these criteria. This thesis shows the author's research and design decisions, not the collective work of the entire team.

Oxime Click-crosslinked Cryogels to Quantify and Target Tumour-associated Macrophage Invasion in Hodgkin Lymphoma
… the design of our HL-tumour mimetic hydrogel: a cryogel comprised of gelatin, hyaluronan, and fibronectin-derived peptides crosslinked using oxime click chemistry. Primary human macrophages seeded thereon migrated to a greater depth in cryogels with greater porosity and pore size; with …

Fluid Dynamic Assessments of Spiral Flow Induced by Vascular Grafts
Peripheral vascular grafts are used for the treatment of peripheral arterial disease and arteriovenous grafts for vascular access in end stage renal disease. The development of neo-intimal hyperplasia and thrombosis in the distal anastomosis remains the main reason for occlusion in that region. The …
