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 ...

Snap-through buckling provides an intricate force-displacement relationship for study. With the possibility for multiple limit points and pitchfork bifurcations and large regions of instability, experimental validation of numerical analysis can become difficult. This requires stabilization of unstable static equilibria, for ...

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 ...

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 ...

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 ...

Solid oxide fuel cells (SOFCs) are one of the most promising candidates for generating clean energy. Also known as “all ceramic” fuel cells, SOFCs use a range of advanced ceramic components to achieve the functionality that is required to attain high levels of efficiency, which exceed most other types of fuel cell systems. ...

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 ...

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 ...

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 ...

The lean blow-out (LBO) of gas turbine combustors is a concern that can limit the rate of descent for an aircraft, the maneuverability of military jets, and cause a costly and time-intensive reignition of land-based gas turbines. This work explores the feasibility of a model-based combustor monitoring for the real-time ...
