A Colorado School of Mines PhD student in materials science has been awarded a NASA fellowship—one of only 14 awarded by the space agency this year—to improve the performance of thermoelectric materials that can be used to power deep-space missions.
Caitlin Crawford, advised by Physics Assistant Professor Eric Toberer, was awarded the NASA Harriett G. Jenkins Graduate Fellowship for her proposal, "Advanced Thermoelectric Materials for Space Power Applications." The fellowship can be renewed for two additional years; Crawford will receive $55,000 for each year of the grant.
Crawford will continue the materials synthesis work she has been doing for the past year at Mines. "We’re looking at a specific type of structure, called the skutterudite structure," Crawford said. "It’s a specific material structure that has really good thermoelectric properties for deep-space power applications."
Michael F. Toney, distinguished staff scientist at the Stanford Synchrotron Radiation Lightsource, part of the SLAC National Accelerator Laboratory, will present "Formation and operation of organic-inorganic halide perovskite solar absorbers" at noon on Thursday, March 24, in Marquez Hall 326 (RESCHEDULED DUE TO WEATHER).
ABSTRACT: To better understand how materials' atomic and mesoscale structure affects their function, it is essential to observe this structure during operation – operando measurements. Similarly, to understand materials synthesis, we must be able to follow the transformation pathways during synthesis (in situ investigations). This talk will give an example of each in situ and operando X-ray scattering and spectroscopy of hybrid organic-inorganic halide perovskite (HOIP) films - unusual solar absorbers presently of considerable interest. I will first present temperature dependent X-ray diffraction from an operating solar cell with an HOIP absorber layer, which allows characterization of the HOIP crystal structure. Our results show how changes in the atomic structure affect the HOIP optoelectronic properties and the device performance. Second, we use in situ X-ray diffraction and spectroscopy to follow the temperature kinetics of HOIP composition and crystal formation, while the HOIP films are annealed after formation from solution. This provides insight into how HOIP formation processes.
ABOUT THE SPEAKER: Michael Toney is head of the Materials Sciences Division and a distinguished staff scientist at the Stanford Synchrotron Radiation Lightsource (SSRL), part of the SLAC National Accelerator Laboratory. He is a pioneer in the use of X-ray scattering, spectroscopy and imaging for the determination of atomic and mesoscale structure of materials used for sustainable energy and for the determination of atomic structure of electrode-electrolyte interfaces. Toney received his BS from Caltech in 1979 and his PhD from the University of Washington in 1983, both in physics. He spent one year as a postdoc at the Risoe National Lab in Denmark, where he participated in some of the first surface X-ray diffraction experiments. He then began working at IBM Almaden Research in materials sciences. He left IBM in 2003 to join SLAC National Accelerator Laboratory and Stanford, where he started programs in sustainable energy materials.
Melissa Teague, who earned her PhD in Materials Science from Mines in 2013, has received the Presidential Early Career Award for Scientists and Engineers, the highest honor bestowed by the United States government on science and engineering professionals in the early stages of their independent research careers.
Teague is a materials engineer at Sandia National Laboratories. She received her PECASE award from the Department of Energy, for her work at Idaho National Laboratory.
Ryan Richards profiled in Mines Magazine
Liu named ABS Endowed Chair in Metallurgical and Materials Engineering
After a competitive international search, Colorado School of Mines Professor Stephen Liu has been appointed the American Bureau of Shipping Endowed Chair in Metallurgical and Materials Engineering.
The nonprofit ABS, which sets standards for the design, construction, and survey of vessels in service, established the endowed faculty chair in March 2014. Liu, a professor in the George S. Ansell Department of Metallurgical and Materials Engineering, served as interim chair until his permanent appointment.
Mines researchers awarded $1.5M to design, improve piezolectrics
Mines researchers have been awarded $1.5 million over four years to design new piezoelectric materials and improve existing ones.
Principal investigator Geoff Brennecka is joined by fellow MME assistant professors Corinne Packard and Vladan Stevanovic; Mechanical Engineering Professor Cristian Ciobanu; Assistant Professor of Applied Mathematics and Statistics Paul Constantine; and Andriy Zakutayev from the National Renewable Energy Laboratory.
The award is from the National Science Foundation’s Designing Materials to Revolutionize and Engineer our Future (DMREF) program. The program seeks to shorten the time for discovering breakthrough materials and bringing them from the laboratory to the marketplace and into products.
Fuel cell research in Science magazine
The development of affordable and efficient ceramic fuel cells that could be used to power homes, the culmination of five years worth of work by Colorado School of Mines researchers, is featured in the July 23 issue of Science magazine.
The research, led by Mines Professor of Metallurgical and Materials Engineering Ryan O’Hayre, would enable more efficient use of natural gas for power generation through the use of fuel cells that convert the chemical energy of a fuel source into electrical energy close to where it is used.
