"Effects of nonthermal plasma on prokaryotic and eukaryotic cells"
… combinations. The discharge profile of a novel nonthermal plasma generator was evaluated in great detail in this dissertation, including its composition, physical characteristics, and effects on biological specimens. Nonthermal plasma was found to have significant effects on cellular physiology. …

Synthesis and Consolidation of Metal Oxide Nanocrystals via Nonthermal Plasma
<p>Nonthermal plasmas offer a unique nonequilibrium environment that has been leveraged in a wide variety of applications in the fields of material processing, lighting, and waste management to name a few. In all of these cases, the plasma serves as a source of high energy electrons, ions, reactive …

Dissipative heating and nonthermal distributions in black hole accretion flaring events
… and radiative transfer calculations with a nonthermal kappa distribution function (which effectively adds a power-law tail to the thermal distribution) for electrons accelerated by resistive heating in reconnecting current sheets. This approach is well supported by the literature on the …

Design and Analysis of Nonthermal Plasma Electrolytic Cells for Ammonia Synthesis
… fuel demand and 1-2 % of global CO2 emissions. Nonthermal plasma-assisted ammonia synthesis is one solution that is able to counter these carbon emissions. The technology has been shown to be a viable and scalable ammonia production alternative to the Haber-Bosch process that also avoids …

Preparation of juice concentrates by nonthermal processing technologies: a multiple hurdle approach
… osmosis (RO) and forward osmosis (FO), as nonthermal technologies for the concentration of liquid foods and beverages. In this study, our objectives were to concentrate fruit juices using FO or a combination of RO and FO and to explore another nonthermal technology that could potentially …

X-ray Radiative Signatures Influenced by Nonthermal Effects in High-Energy-Density Laboratory Plasmas of Mid-Atomic-Number Z-pinches
… for diagnosing HED plasmas, where thermal and nonthermal x-ray features describe, in general, "hot" and "cold" plasmas, respectively. This dissertation focuses on identifying and characterizing nonthermal effects and radiative properties in HED laboratory Z-pinch plasmas. Nonthermal effects …

Analytical evaluation of microplasma technologies for production of hydrogen fuel from water
… limitations. Microplasma technologies utilize nonthermal and non-Maxwellian reaction conditions in nonconventional chemical reactions and could provide novel pathways to producing H2 fuel. The current work is the first demonstration of H2 production from H2O with microplasma technologies. …

Photoinduced phase transitions studied by femtosecond single-shot spectroscopy
… modeling, double pump measurements reveal nonthermal melting occurring in bulk and thin Bi films. A higher threshold fluence for nonthermal melting is observed in bulk bismuth as compared to thin films, suggesting ultrafast carrier dynamics such as ballistic transport. In addition to …

Direct and inverse turbulent cascades in a 2D Bose gas
… dynamics, consistent with the framework of nonthermal fixed points, and scaling in the high-k dynamics consistent with weak-wave turbulence theory. In the third and final experiment, we drive the 2D Bose gas at a scale much smaller than the system and observe a steady-state inverse cascade, …

EUV Spectroscopy of Solar Active Region Jets
… temperature, velocities (plane-of-sky, Doppler, nonthermal) and filling factors. In addition, the relationship between AR jets and other phenomena such as photospheric magnetic activity, nonthermal type-III radio bursts and soft/hard X-ray emission has been studied using the Helioseismic and …

Isothermal microwave biology : catalysis and fermentation
… experiments conducted conclude that there is a nonthermal, nonlinear response between the exposure microwave power and rate and yield of cellulose saccharification. The nature of the nonthermal response is controversial and may be dependent on the definition of "nonthermal,' leading to ambiguity …

Pushing the limits of performance. is it really mind over matter? an investigation into the effects of menthol mouth rinsing and the capacity for fatigue amelioration in trained adolescent male cyclists under heat stress
… varied to MEN, results demonstrate that a nonthermal cooling agent that acts on the CNS can benefit power regulation during a stochastic cycling task without causing additional decline in perception, as suggested by the central fatigue hypothesis.

Electron acceleration at localized wave structures in the solar corona
… electrons, considered to be the source of the nonthermal radio and X-ray radiation. One of the most important and still open question in solar physics is how the electrons are accelerated up to high energies within (the observed in the radio emission) short time scales. Because the acceleration …

Optical and Interface-Based Methods of Defect Engineering in Silicon
… The optical method elucidates the origin of a nonthermal influence of illumination on boron diffusion. The results show that photostimulated changes in diffusion stem primarily from light interacting with interstitial clusters as they dissociate rather than point defect-mediated changes to …

Development of Histotripsy Focused Ultrasound Devices Using Rapid Prototyping Methods
Histotripsy is a nonthermal ultrasound therapy used to treat cancer noninvasively by tissue mechanical fractionation with cavitation bubble clouds. Histotripsy is conducted through focused ultrasound transducers, where the piezoceramic (PZT) plate or disc, which emits the ultrasound wave, is the …
