Transport and segmental relaxation in polymer networks
… role in enabling advanced material applications, including energy storage, ion separation, and polymer recycling. This thesis explores the transport mechanisms of ions and penetrants in polymer networks and the influence of curing conditions on network performance. Through a combination of …

Nonlinear ion transport at high electric currents in shock electrodialysis and ion-intercalation memories
This thesis studies the nonlinear ion transport at high electric currents, in two applications: shock electrodialysis (shock ED) for ion separation, and ion-intercalation memories for in-memory computing. The two studies are both related to the concept of concentration polarization (CP) in …

Two-ion control and polarization forces for precise mass comparisons
… the ability to compare the masses of single ions by an order of magnitude to a fractional accuracy of [approx.] 7 x 10-12. This is done by simultaneously confining two ions in a Penning trap, and simultaneously comparing their cyclotron frequencies which are inversely proportional to the …

Synthesis and characterization of poly(2,2,2- trifluoroethoxyphosphazene)polystyrene graft copolymers
… were synthesized by a “grafting onto" reaction which involved a reaction between two preformed, reactive polymer chains. In this case, poly(dichlorophosphazene) was the reactive polymer backbone onto which approximately 10 weight percent polystyrene chains were grafted. In order to avoid …

Characterization of Collisional Shock Structures Induced by the Stagnation of Railgun-driven Multi-ion-species Plasma-jets
… involved in many physical systems. Specifically, ion-species separation caused by a shock wave propagating through a plasma is an important but not yet well understood phenomenon. In inertial confinement fusion implosions, a shock wave precedes the rapid compression of a fuel pellet to ignition …

Picosecond Infrared Lasers (PIRL): Applications in Biodiagnostics and Towards Quantitative Mass Spectrometry
… selectively excite water to directly drive ablation of biological tissue faster than any competing energy dissipation process that could damage surrounding tissue. This thesis work showed that this mechanism can be exploited for a new form of spatially resolved mass spectrometry with the prospect …

Redox-active materials for electrochemically-mediated separations
Separation processes are ubiquitously employed for purification purposes in chemical production, as well as potable water generation and environmental remediation. The rising intensity of global issues such as the growing world population, low water security, and worsening industrial pollution all …

Polypyrrole-containing Composite Particles: Preparation, Characterization and Application
This research is focused on preparation of polypyrrole (PPy) composite particles by using socalled template oxidative polymerization method. As a template, water-soluble polymers, polymeric microgels, latex particles or bulk gels can be used. The morphology and properties of the composite particles …

Engineering efficient desalination systems: Materials development and systems analysis in capacitive deionization
Climate change and population growth are increasingly rendering traditional water sources inadequate in many regions. Accordingly, desalination of unconventional water sources such as brackish aquifers, which has been historically cost prohibitive, will be necessary to provide more sustainable …
