Artificial Micro-Devices: Armoured Microbubbles and a Magnetically Driven Cilium
Micro-devices are developed for uses in targeted drug delivery and microscale manipulation. Here we numerically and analytically study two promising devices in early stages of development. Firstly, we study Armoured Microbubbles (AMBs) which can self-propel as artificial microswimmers or facilitate …

The redesign and reconstruction of a five-inch magnetically-driven centrifugal molecular still
… to redesign and reconstruct a five-inch magnetically-driven centrifugal molecular still, and by so doing to eliminate leaks around the rotor shaft by enclosing the rotor within the still head, and to gain flexibility by the use of a high-form bell jar, and a water-cooled condenser. The …

Magnetically-driven Therapeutic Agents Delivery System using Iron Oxide Nanocages and Enhancement of Exosome Secretion, a Potential Biological Drug Delivery Carrier
… drug carrier.</p> <p>Chapter 2 discusses a magnetically driven nanoparticle therapeutic agent delivery system, which efficiently modified the gene expression post-transcriptionally. In this work, we examined whether the caged-shaped 20nm iron oxide nanoparticles (IO-nanocages) can escape …

The effect of condenser temperature and location on the molecular distillation characteristics of stearic acid
… This investigation was accomplished using a magnetically driven centrifugal molecular still with a five-inch rotor and employing the following operating conditions: operating pressure, 24 ± 2 microns of mercury, absolute; feed rate, 60 to 65 milliliters per minute; rotor speed, 1000 ± 50 …

Verification and Validation of Magnetohydrodynamics Simulations of Electrically Exploded Conductors
Dense Z-pinches, magnetically-driven flyer plates, and electrically exploded wires and foils all take advantage of the extreme Lorentz forces and/or Ohmic heating generated by intense electrical current pulses through an initially solid conductor. Magnetohydrodynamics (MHD) simulations are used to …

Development of a large displacement flexure based nano-precision XY positioning stage for vacuum environments
… lead to less expensive designs as compared to magnetically-driven bearings. This dissertation presents a large displacement flexure based nano-precision XY positioning stage for vacuum-based semiconductor equipment. The weight support mechanism of the motion stage is made of links and flexure …

Magnetic Steering to Save Sight: Trabecular Meshwork Cell Therapy as a Treatment for Primary Open Angle Glaucoma
… hypothesis of this work is that an optimized magnetically-driven TM cell therapy can lead to long-term clinically significant levels of IOP reduction while minimizing the risks associated with unwanted off-target cell-delivery. This work resulted in the development of a novel magnetic TM cell …

High-temperature superconductivity in a family of iron pnictide materials
… for a transition coupling weakly to strain but driven by another order parameter. My observations allow several statements about the symmetry of the order parameter and are suggestive of a non-magnetically driven structural transition. In the case of doped samples a much richer behavior is seen, …
