- 요약This dissertation demonstrates three methods for material characterization: multibubble sonoluminescence, cavitation analysis, and sediment dynamics, where advancements have been made by combining collateral optical and rheological techniques with acoustics. Sonoluminescence (SL) is the process in which a bubble driven by acoustic waves collapses and produces light. It has been shown in the literature that the fluid content of both the host liquid and the gas of the bubble has an effect on the light output. One such study investigated the multibubble sonoluminescence (MBSL) light emission in blood plasma as a potential medical diagnostic tool. This work presents an experimental apparatus for creating MBSL as well as measurements and analyses of the resulting MBSL light production in two host substances. These experiments were conducted in materials of biological significance to characterize the fluid content. The second body of work relates to cryopreservation. In this field there exists a class of substances known as cryoprotectant agents (CPAs), which display an ability to prevent ice formation upon cryogenic freezing via vitrification. These CPAs are used to prevent cellular damage during the preservation of human tissues. In a vitrified state, cells exist in a glass-like state, meaning there is no formation of mechanically damaging ice crystals during cryogenic freezing and thawing. Although a CPA's ability to vitrify increases with concentration, its toxicity limits viable levels of use. This work investigated a suite of acoustic properties of CPAs via analyses of cavitation noise and cavitation jets for future studies on CPA toxicity. The acoustic spectra of each CPA show an observable dependence on concentration levels and provide a potential way to probe the hydrogen bonding dynamics within the mixtures. The third and final portion of this work relates to sediment characterization. Fine-grained ocean-bottom sediments are often modeled as fluids, despite having some finite rigidity. They contain grains that experience electrochemical forces related to electrostatic charges and electrolytic pore fluids but the nature of these forces and how they affect sediment rigidity, and in turn their acoustic properties is not well-understood. In this work, the salinity- and temperature-dependent behaviors of two types of kaolinite materials were studied by observing sediment settling, rigidity, rheological properties, and longitudinal sound speed using joint acoustical, rheological, and optical techniques.
