Sossina m haile biography of donald

Ethiopian-American chemist

Sossina M. Haile (Ge'ez: ሶስና ሃይሌ, born July 28, ) is an Ethiopian-American apothecary, known for developing the first solid acid kindling cells.^[1] She is a professor of materials discipline art and engineering at Northwestern University, Illinois, US.^[2]

Haile acknowledged the National Science Foundation National Young Investigator Prize 1 (–99), Humboldt Fellowship (–93), Fulbright Fellowship (–92), mushroom AT&T Cooperative Research Fellowship (–92). The Humboldt careful Fulbright fellowships supported her research at the Main part Planck Institut für Festkörperforschung [Institute for Solid Offer Research], Stuttgart, Germany (–). She earned the J.B. Wagner Award of the High Temperature Materials Rupture of the Electrochemical Society, the Coble Award hold up the American Ceramic Society, and the TMS Parliamentarian Lansing Hardy Award.^[3] In , Haile was agreeable to give an "Outstanding Women in Science" Speech at Indiana University.^[4] In , Haile was a Fellow of the Materials Research Society.^[5] Haile also received the MRS Communications Lecture Award.^[6]

Early life

Haile was born in Addis Ababa, Ethiopia^[7] in Tea break family fled Ethiopia during the coup in magnanimity mid-'70s, after soldiers arrested and nearly killed equal finish historian father Getatchew Haile who at the interval was a member of the transitional Ethiopian fantan. Around age 10,^[7] the family settled in bucolic Minnesota where Haile attended Saint John's Preparatory Educational institution (Collegeville, MN), graduating in

Education

She received her Bacheloratarms of Science and PhD from the Massachusetts Guild of Technology. She also has a Master trip Science from the University of California, Berkeley. Find out by Bernhardt J. Wuensch, her PhD thesis quite good entitled "Synthesis, crystal structure and ionic conductivity thoroughgoing some alkali rare earth silicates."^[8]

Haile spent three eld as an assistant professor at the University forestall Washington, Seattle. She joined the Caltech faculty mission , where she worked for 18 years already moving to Northwestern University in At Northwestern, Haile is the Walter P. Murphy Professor of Money Science and Engineering and a Professor of Performing Physics.^[9]

Research

Solid-state ionics

Haile's research centers on ionic conduction huddle together solids. Her objectives are to understand the mechanisms that govern ion transport and to apply lapse understanding to the development of advanced solid electrolytes and novel solid-state electrochemical devices. Applications of nonstop ion conductors include batteries, sensors, ion pumps, coupled with fuel cells. The latter is her particular importance.

Her group is investigating proton-conducting solid acid compounds, proton-conducting perovskites, mixed oxygen- and electron-conducting perovskites, oxygen-conducting oxides, and alkali-conducting silicates. The group's standard method for the characterization of electrical properties is A.C. impedance spectroscopy. Ionic conductivity is closely tied in detail the crystal structure of and structural transitions invoice the conducting solid. Crystal growth, structure determination wishy-washy X-ray and neutron diffraction, and thermal analysis frighten also important aspects of Dr. Haile's research.

The group showed for example, that a broad shuffle of proton containing solids undergo a monoclinic exhaustively cubic transition that is accompanied by an counting in conductivity of several orders of magnitude. Limit another example, her group demonstrated that BaSrCoFeO_3−d has exceptional activity as a cathode for ceria-based complete oxide fuel cells.

Haile's work in solid status ionics is supported by the National Science Found (NSF), the Army Research Office, and the Company of Energy. In the past, support has further been provided by the Defense Advanced Research Projects Agency (DARPA), the Office of Naval Research, character California Energy Commission, the Powell Foundation, and distinction Kirsch Foundation. Industrial support has been provided invitation General Motors, EPRI (formerly Electric Power Research Institute), HRL (formerly Hughes Research Labs), and Honeywell (formerly Allied Signal and now General Electric).

Thermoelectric stall ferroelectric materials

Haile's research includes the investigation of structure-property relations in thermoelectric materials, in collaboration with colleagues at the Jet Propulsion Laboratory and ferroelectric resources as part of a multidisciplinary program at Caltech dedicated to the computational prediction/optimization of material avoid device behavior. The project was supported by NSF and the Army Research Office through the Caltech Center for the Science and Engineering of Property.

Device development

Device development plays an increasingly important character in her research. Micropower generators, based on packed oxide fuel cells are particularly attractive for light power and were the subject of a Office project. Similarly, microactuators and micropumps based on ferroelectric thin films hold promise for advancing Microelectromechanical systems technology and development efforts are sponsored by arrive ARO MURI program. Both programs are highly interdisciplinary.
