Electrochemical Fabrication Of Elastin-Containing Bi-Layered Scaffold For Vascular Tissue Engineering Applications, Thuy-Uyen Ky Nguyen

Theses and Dissertations

Lack of a viable vascular graft for the replacement of diseased small diameter blood vessels (< 4 mm) has encouraged the development of a self-repairing tissue engineered vascular graft (TEVG) as a promising alternative source. Although many different fabrication approaches have been devised to generate TEVGs using both natural and synthetic biomaterials, a functional TEVG that can serve as an effective replacement of diseased small-diameter blood vessels (< 4 mm) is still elusive mainly due to concerns associated with thrombosis and intimal hyperplasia. One approach to improve the clinical outcome of vascular grafts is to develop a 3D biomimetic scaffold that provides the essential physicochemical cues (i.e., compositional, topographical) to modulate cellular response (i.e., cell phenotype, endothelialization, de novo elastic matrix production) and thereby aid in tissue repair and remodeling. This approach entails the development of a novel 3D scaffold that provides an aligned collagen platform to guide smooth muscle cell (SMC) orientation

and insoluble elastic matrix (i.e., native form of elastin) to promote SMC contractility and thereby prevent overproliferation and hence alleviate concerns with intimal hyperplasia. In addition, the scaffold must comprise of a smooth luminal side to support the formation of a continuous endothelium that is essential to prevent thrombosis. Most existing biofabrication methodologies to generate vascular scaffolds (e.g., extrusion, electrospinning) have limited scope because of the inability to incorporate insoluble elastic matrix within the aligned collagen framework due to the disparity in the size …

Modeling Multirotor Aerodynamic Interactions Through The Vortex Particle Method, Eduardo Alvarez, Andrew Ning

Faculty Publications

Distributed electric propulsion and vertical take-off and landing has recently opened a new design space for urban air mobility. However, the use of multiple rotors operating in close proximity introduces complicated aerodynamic interactions that are not well understood, are not captured through conventional design tools, and need to be addressed in the conceptual design stage. This study investigates the accuracy of the viscous vortex particle method (VPM) in modeling rotor-on-rotor aerodynamic interactions in a side- by-side configuration as encountered in tilt-rotor, quadrotor, and distributed propulsion aircraft.
