Opportunity Description

Research on High-Energy-Density Dielectrics and Capacitors for Power Electronics and Pulsed Power Applications In the current and future propulsion and more electrified systems, capacitors are essential in power electronic circuits for efficient power conditioning. In future electromagnetic based guns, protection systems and directed energy systems, capacitors are also essential for providing needed pulsed power for the operation of these systems. Current capacitors cannot meet the high-temperature, high-energy density and graceful fading that are required for the propulsion and other electrified systems. Similarly, the state-of-the-art capacitors are too bulky to fit into the platforms for most of the pulse power applications. To meet the challenges, our research focuses on the following areas. The first area includes the identification of high-energy-density high-temperature dielectrics and the development of process for fabrication of promising dielectrics into high quality capacitor grade films. The second area relating to conversion of the dielectric films before they are assembled into capacitors includes the metallization and coating techniques for enhancing self-clearing, at the same time, current carrying capability. The third area involves development of novel designs and assembly methods for minimizing the field enhancement at the dielectric edge and maximizing the use of dielectrics for high-energy density and high voltage packaging for pulsed power applications. The fourth area includes the development of pulse power systems optimizing capacitors with other components such as switches and loads.

About Us

Grooming future leaders in science and technology requires enhancing the skills, knowledge and experience of workers early in their careers. To that end, ORAU (Oak Ridge Associated Universities) assists in connecting the best and most diverse students, recent graduates, faculty and professionals with world-class fellowships, internships and jobs, whether in national laboratories, research institutions, federal government offices or private sector R&D departments.

ORAU works with agencies such as the U.S. Army Research Laboratory (ARL) Research Associateship Program (RAP) allow Postdoctoral Fellows, Journeyman Fellows (undergraduate and graduates students and recent graduates), Senior Researchers, and Summer Faculty engage in research initiatives of their own choice, that are compatible with the interests of the government and will potentially contribute to the general effort of the ARL. We work with the Environmental Protection Agency (EPA) to place recent graduates in full-time and part-time jobs in the Office of Research and Development at EPA under the National Student Services Contract. ORAU also works with Center for Medicare and Medicaid Innovation.

Research opportunities include, but are not limited to the following disciplines: Aerospace Engineering, Anthropology, Archeology, Biology, Biochemistry, Biological Engineering, Biomechanical Engineering, Biomedical Engineering, Chemical Engineering, Chemistry, Computer Science, Computer Engineering, Data Science, Electrical Engineering, Environmental Health Risk Assessment, Environmental Science, Entomology, Epidemiology, Ergonomics, Geology, Health Education Mechanical Engineering, Materials Science, Mathematics, Nanotechnology, Photonics, Physics, Public Health Economics, Public Health Policy, Toxicology, and more.

If you are ready to take the next step in your career path, then we are ready to help you!
