Experimental Characterization And Manufacture Of Polymer Nanocomposite Dielectric Coatings For High-Temperature Superconductor Applications, Jacob Ryan Mahon May 2022

Experimental Characterization And Manufacture Of Polymer Nanocomposite Dielectric Coatings For High-Temperature Superconductor Applications, Jacob Ryan Mahon

Theses and Dissertations

Increased implementation of high-temperature superconducting (HTS) power transmission has the potential to revolutionize the efficiency of electrical grids and help unlock a fully electric transportation infrastructure. Realizing the benefits of HTS systems has been impeded by a lack of available dielectric insulation materials that can 1) withstand the extreme cryogenic operating environment of superconductors and 2) demonstrate low temperature processing that is compatible with existing superconductor manufacturing methods. Solving this problem necessitates a high-performance dielectric material with multifunctional properties specifically suited for operation in HTS systems. A polyamide and silicon dioxide (PA/SiO2) nanocomposite material with exceptional thermal stability has been …


Design Improvement Of Transcatheter Aortic Valves For Aortic Stenosis Patients, Samantha K. Shoun, Ali N. Azadani May 2022

Design Improvement Of Transcatheter Aortic Valves For Aortic Stenosis Patients, Samantha K. Shoun, Ali N. Azadani

DU Undergraduate Research Journal Archive

Aortic valve disease is a common condition in patients above 60 years of age and is associated with significant morbidity and mortality. Aortic valve stenosis is characterized by the narrowing of the aortic valve, which can be quite debilitating. This disease is treated with transcatheter aortic valve replacement (TAVR), which is a rapidly expanding alternative to open-heart surgical aortic valve replacement (SAVR). Although TAVR is a less invasive than SAVR, long-term durability of the transcatheter aortic valves could be the Achilles heel of the procedure. Thus, the main objective of this research was to improve the design of transcatheter aortic …
