Microfluidics enhanced synthesis of micellar nanostructures
Surfactant molecules can self-assemble into various morphologies under proper combinations of surfactant concentration, temperature, and flow conditions. In equilibrium, micelles can transition from entangled to branched structures with increasing ionic strength and temperature. Under flow conditions, micellar structure ...
Computational and Experimental Investigation into the Hemodynamics of Endovascularly Treated Cerebral Aneurysms
This thesis investigates the influence of mechanical stresses and fluid motion on the efficacy of endovascular treatment methods for cerebral aneurysms. The two primary endovascular treatments, embolic coils and flow-diverting stents, are designed to reduce blood-flow and stress inside the aneurysm volume - creating an ...
Development of Optimal Electromagnetic Resonance Rewarming Technology for Cryopreservation
The development of successful cryopreservation technology has been restricted to small biological materials due to the limited effective rewarming techniques. Either for conventional cryopreservation techniques which remain a certain fraction of ice crystals or vitrification which aims to exclude ice crystal in the subzero ...
Advanced Methods to Produce and Characterize Transport Properties of Novel Nanoporous Polymers
In this work, experimental techniques, equipment, apparatuses, models, algorithms, and software codes were developed to explore the nanoporous structure of polyetherimide (PEI) created using the solid-state foaming process. First reported in 2001, researchers have wondered about the transport properties of this skin-covered ...
A Passive Pediatric Exoskeleton to Improve the Walking Ability of Children with Neuromuscular Disorders
Children with neuromuscular disorders, such as cerebral palsy (CP) often have walking limitations. Assistive devices for home use, such as walkers and crutches, may not provide optimal participation opportunities or lead to effective walking dosage. Even with therapy and assistive devices, children with CP get significantly ...
Finite Element Modeling of Brain Injury for Performance Evaluation of Football Helmets
Football helmets worn today are primarily designed to prevent skull fracture and irreversible brain injury. In that limited respect, today’s helmets are a success with the frequency of reported football-related skull fracture a rare occurrence. In recent decades, however, concussion, mild traumatic brain injury (mTBI), and ...
Planar Aerial Reorientation of an Insect Scale Robot Using Piezo-Actuated Tail Like Appendage
Robots today, though capable of performing a growing number of increasingly complex tasks, lack the agility that would be required to perform in a rapidly changing or dynamic environment, especially when compared to animals and insects, they are very rigid in performance. Recent developments in the field of insect-scale ...
Transverse Plane Rotational Misalignment of Ankle Arthrodesis and Arthroplasty in Cadaveric Gait Simulation
End-stage arthritis of the ankle is a debilitating disease that is commonly treated surgically with arthrodesis and arthroplasty of the ankle joint. Misalignment of the ankle joint occurs in both of these surgeries, and for both procedures, misalignment can negatively impact patient outcomes. The goal of this thesis was to ...
GPU-based Parallel Computation of Integral Properties of Volumetrically Digitized Objects
Integral properties of objects that have been created digitally or that are volumetrically digitized have an important role in many different applications. There are a few different approaches for the computation of integral properties. In this dissertation, direct integration methods, using a convergence proof that exists ...
EVAPORATION OF LIQUID DROPLETS ON FLAT AND CURVED SOLID SUBSTRATES
We study the evaporation of liquid droplets on flat and curved heated substrates. We derive an evolution equation for the drop thickness to evaluate its shape as it evaporates on a curved substrate. We adopt a one-sided model with thermal control which, together with the lubrication approximation, results in an evolution ...
