Domain-Engineering Enabled Thermal Switching in Ferroelectric Materials

Sponsor: National Science Foundation (NSF)

Start Date: 7/01/20

End Date: 6/30/24

Abstract

The research goal is to understand how thermal conductivity of ferroelectric materials can be switched with external electric fields and how this switching behavior can be engineered through the reconfigurable ferroelectric domains. This is motivated by the possible new paradigm of energy regulation for harvesting, saving, and management if dynamic control of thermal energy transport can be achieved. Seeking solutions for thermal control in materials are limited by the traditional toolkit of linear, static, and passive thermal components, such as thermal resistors and thermal capacitors. This paucity of thermal options pales in comparison to the rich selection of highly nonlinear, switchable, and active components in the electrical domain. Since switchable and nonlinear thermal components are not nearly as mature as their electrical counterparts, the pursuit of these thermal components remains a motivating interdisciplinary challenge to researchers for years. In this project, we will measure the thermal conductivity- domain structure correlation to reveal the effects of domain walls and domain engineering. The studies on the manipulation of domain walls using domain engineering has translational implications for a range of applications, such as infrared imaging, solid-state cooling, and waste-heat energy conversion due to pyroelectric and electrocaloric effects, and sensors based piezoelectric effects.

Abstract

We will develop low cost sensor arrays that can be attached to an ultrasound probe and collect real-time position, orientation, force (between probe and maternal abdomen) and the probe temperature data that is synchronized with the sonograms. Once developed these sensors will be adopted into a clinical algorithm and this additional data collected on all ultrasound scans. The proposed sensor system can be used for automatic ultrasound scan for medical imaging.

Ultrasonic Characterization of Atherosclerotic Plaque using Multiple Scattering

Sponsor: National Institutes of Health (NIH)

Start Date: 9/30/16

End Date: 7/31/19

Abstract

Atherosclerosis is the leading cause of morbidity and mortality in Western countries, in large part due to plaque rupture. Vulnerable plaques are the most likely to rupture, being the major cause of acute myocardial infarction and sudden cardiac death. Neovascularization of the arterial walls by adventitial vasa vasorum appears to participate in the progression of atherosclerosis and atherosclerotic plaque neovascularization was shown to be one of the strongest predictors of future cardiovascular events. No techniques are currently available for the quantitative assessment of vulnerable plaque, which remains an unmet need. Microbubbles are extremely powerful contrast agents for ultrasonic imaging of the vasculature and Contrast Enhanced IntraVascular UltraSound (CE-IVUS) seems to be one of the most promising imaging modalities for the detection of atherosclerosis and vulnerable plaque. However, although this technique allows the detection of the vasa vasorum, CE-IVUS currently does not provide a quantitative characterization of its micro-architecture. The specificity of CE-IVUS has to be improved. A quantitative assessment of the vasa vasorum network in vivo would strongly predict cardiovascular events yet no such techniques currently exist. We propose using ultrasound multiple scattering to characterize the microstructural properties of neovascular networks. By using ultrasound multiple scattering to characterize the architecture of the neovascularization, we will add a new dimension to CE-IVUS. With the technique we propose to develop here, CE-IVUS will not only be used for the detection of plaque related neo-angiogenesis, but also for its characterization. This will dramatically increase the specificity of CE-IVUS for the assessment of plaque vulnerability. It will enable the ultrasonic assessment of the vasa vasorum to become a widely used clinical tool for screening, diagnosis and monitoring of plaque vulnerability.
