Tribal Colleges and Universities/American Indian Research and Education Initiatives Advanced Manufacturing Technical Assistance Project

Atcitty, Stanley

The overall goal of this project is to establish a network of TCUs with essential advanced manufacturing (AM) facilities, associated training and education programs, and private sector and federal agency partnerships to both prepare an American Indian AM workforce and create economic and employment opportunities within Tribal communities through design, manufacturing, and marketing of high quality products. Some examples of high quality products involve next generation grid components such as mechanical energy storage, cabling for distribution of energy, and electrochemical energy storage enclosures. Sandia National Laboratories (Sandia) is tasked to provide technical advising, planning, and academic program development support for the TCU/American Indian Higher Education Consortium (AIHEC) Advanced Manufacturing Project. The TCUs include Bay Mills Community College (BMCC), Cankdeska Cikana Community College (CCCC), Navajo Technical University (NTU), Southwestern Indian Polytechnic Institute (SIPI), and Salish Kooteani College. AIHEC and Sandia, with collaboration from SIPI, will be establishing an 8-week summer institute on the SIPI campus during the summer of 2017. Up to 20 students from TCUs are anticipated to take part in the summer program. The goal of the program is to bring AM science, technology, engineering, and mathematics (STEM) awareness and opportunities for the American Indian students. Prior to the summer institute, Sandia will be providing reviews on curriculum plans at the each of the TCUs to ensure the content is consistent with current AM design and engineering practice. In addition, Sandia will provide technical assistance to each of the TCUs in regards to their current AM activities.

Technical Advisor to the American Indian Research and Education Initiatives (AIREI)

Atcitty, Stanley

The American Indian Research & Education Initiative (AIREI) is a pilot program that started in 2011 and is funded by the US Department of Energy (DOE) Economic Impact & Diversity and National Nuclear Security Administration in partnership with the American Indian Higher Education Consortium (AIHEC) and the American Indian Science and Engineering Society. AIREI brings science, technology, engineering, and mathematics (STEM) research and education funding to Tribal Colleges and Universities (TCU) and other US universities. AIREI has funded eight schools, including four pairs of tribal colleges and mainstream universities, in order for student and faculty research teams to bring energy projects to tribal lands. The research team from Southwest Indian Polytechnic Institute (SIPI) and Northern Arizona University (NAU) has performed a student-centric research and analysis feasibility study of a potential utility-scale solar power plant on the Jemez Pueblo reservation trust land. The research team from Navajo Technical University (NTU) and Arizona State University (ASU) has assessed the effectiveness of solar photovoltaic (PV) system designs in meeting the electricity demands of Navajo Tribal homes and public buildings in addition to the development of a solar technology curriculum that incorporates the outcomes of this study, helping to advance PV system design and installations on local Tribal lands. The Little Big Horn College (LBHC) and Montana State University-Bozeman (MSUB) team has developed fast growing strains of nitrogen-fixing cyanobacteria to help advance carbon capture and sequestration (CCS) technologies. The research supported the Crow Nation reservation as it evaluates opportunities for coal-to-liquid fuel and CCS projects. The Sinte Gleska University (SGU) and South Dakota School of Mines (SDSM) team developed computer modeling and simulation technologies to evaluate the feasibility of oil and gas development from the Niobrara Formation on the Rosebud Sioux reservation. Through this project, the students developed skills in applied energy-related research involving computer simulation, chemistry, geology, and petroleum engineering. AIREI supports collaboration between these universities and connects the teams with the technological expertise and mentorship opportunities provided through Sandia National Laboratories (Sandia).

Applied Physics Letters

Paisley, Elizabeth; Brumbach, Michael T.; Allerman, A.A.; Atcitty, Stanley; Baca, Albert G.; Armstrong, Andrew A.; Kaplar, Robert; Ihlefeld, Jon F.

Epitaxial (111) MgO films were prepared on (0001) AlxGa1-xN via molecular-beam epitaxy for x=0 to x=0.67. Valence band offsets of MgO to AlxGa1-xN were measured using X-ray photoelectron spectroscopy as 1.65±0.07eV, 1.36±0.05eV, and 1.05±0.09eV for x=0, 0.28, and 0.67, respectively. This yielded conduction band offsets of 2.75eV, 2.39eV, and 1.63eV for x=0, 0.28, and 0.67, respectively. All band offsets measured between MgO and AlxGa1-xN provide a>1eV barrier height to the semiconductor.

Electrochemical Solution Growth of Bulk GaN for Power Electronics Substrates, Final Report

Monson, Todd; Atcitty, Stanley

This project focused on developing a novel, scalable, and economic growth technique for bulk gallium nitride (GaN), a critical material for next-generation high-temperature power electronics. Large area, high-quality bulk GaN is required as a substrate material in order to grow highly efficient bipolar transistors for inverters and power conditioning. Attempting to grow GaN in bulk by traditional precipitation methods forces extreme thermodynamic and kinetic conditions, putting these techniques at the extremes of experimental science, which is unsuitable for large-area, cost-effective substrate growth. The Electrochemical Solution Growth (ESG) technique is a novel concept that addresses these issues in a unique way, and was developed at Sandia National Laboratories (SNL), in part under this program. The crucial step in demonstrating the technique’s feasibility was to deposit high-quality GaN on a seed crystal. The bulk of SNL’s activities were focused on developing conditions for deposition of GaN on a seed crystal (a thin film of GaN grown by metal organic chemical vapor phase deposition (MOCVD) on c-axis oriented sapphire) in a molten salt electrolyte solution using a rotating disk reactor (RDR) ESG apparatus. This project was actively funded from FY08 to FY12 by the Energy Storage Program and GaN Initiative for Grid Applications (GIGA) program of the Office of Electricity Delivery and Energy Reliability (OE) in the U.S. Department of Energy (DOE). Some activities focused on silicon doping of GaN occurred in FY13 but only through the use of carryover funds.

Multi-Objective Optimization for Power Electronics used in Grid-Tied Energy Storage Systems

Atcitty, Stanley; Hambridge, Sarah

Multi-objective optimization is used to find a nondominated set of solutions for two conflicting performance metrics or objective functions. These functions are dependent variables in the system, controlled by a set of independent variables called decision variables. The decision variables represent the inputs to the problem, chosen by the system designer, and are values listed in the solution set. In this study, a multi-objective genetic algorithm compared insulated-gate bipolar transistor (IGBT) failure rate to filter and cooling system costs. This study demonstrated the use of multi-objective optimization for energy storage systems. IGBT failure rate was compared to its associated filter and cooling-system costs as part of the DC-AC inverter power electronics system in a battery energy storage system (BESS). The independent or decision variables were determined to be switching frequency and thermal resistance of a heat sink, Rsink. The final results indicated that high values of switching frequency increased the effects of Rsink. Future work will add additional objective functions and decision variables to the study to optimize additional components in the power electronics system and BESS.
