Ablation Dynamics and Instabilities of Metallic Plasmas Generated Using Mega-Ampere-Scale Current Drivers.
(2011)
This dissertation represents an experimental investigation quantifying the degree of azimuthal correlation between ablating wire cores in wire array Z-pinch loads, as well as a theoretical and experimental investigation ...
Enhanced Light Collection from Single Trapped Ions.
(2011)
Long-range transport of quantum information across a network is most readily achieved through the use of photons as the information carriers. The nodes of such a quantum network are most naturally a quantum memory or ...
Laser Fabrication of High-K Dielectrics for High Current Cathodes.
(2008)
Triple point, defined as the junction of metal, dielectric, and vacuum, is the location where electron emission is favored in the presence of a sufficiently strong electric field. Recent work at the University of Michigan ...
Electron Field Emission from Boron Nitride Thin Films.
(2008)
A systematic study of electron field emission from boron nitride thin films is presented, establishing nanostructured thin film cubic boron nitride (cBN) as a robust and chemically inert material with a low effective ...
Optical and Magnetic Manipulation of Hybrid Micro and Nanoparticle Sensors.
(2008)
Microparticles and nanoparticles have been used in a wide variety of applications ranging from biomedical to optical and electronic technologies. The microscopic and mesoscopic size scale of single particles makes them ...
Few-Cycle and Sub-Cycle Metrology for the Characterization of High Harmonics.
(2009)
The rapid advances in the generation of ultra-short optical pulses in recent decades have often outstripped the ability of metrologists to accurately measure the pulses' temporal profiles. With each reduction in pulse ...
Full-wave Nonlinear Inverse Scattering for Acoustic and Electromagnetic Breast Imaging.
(2012)
Acoustic and electromagnetic full-wave nonlinear inverse scattering techniques are explored in both theory and experiment with the ultimate aim of noninvasively mapping the material properties of the breast. There is ...
Coherence Recovery in Random Environments Using the Autoproduct
(2023)
The study of wave propagation is a mature field of research with numerous avenues of theoretical, numerical, and experimental investigation. A prominent application is remote sensing, where recorded acoustic or electromagnetic ...
Device Physics and Applications of Ternary Organic Photovoltaics
(2023)
Organic photovoltaics (OPVs) are emerging as an attractive candidate for solar energy harvesting due to their advantages in environmental compatibility, low-cost, flexibility and transparency. The past few decades have ...
A framework for advancing sustainable magnetic resonance imaging access in Africa
(RAD-AID InternationalWiley Periodicals, Inc., 2023-03)
Magnetic resonance imaging (MRI) technology has profoundly transformed current healthcare systems globally, owing to advances in hardware and software research innovations. Despite these advances, MRI remains largely ...
