Sossina M. Haile

Sossina M. Haile ( Ge'ez   , amuru Julaị 28, 1966) bụ onye America chemist, mara maka imepụta mkpụrụ ndụ mmanụ acid siri ike nke mbụ.  Ọ bụ prọfesọ nke sayensị akụrụngwa na injinia na Mahadum Northwwest, Illinois, US. "Sossina Haile: The Power Behind Cooler, Greener Energy", Newsweek published December 22, 2007 (accessed November 18, 2010)

Haile natara National Science Foundation National Young Investigator Award (1994-99), Humboldt Fellowship (1992-93), Fulbright Fellowship (1991-92), na AT&T Cooperative Research Fellowship (1986-92). Mmekọrịta Humboldt na Fulbright kwadoro nyocha ya na Max Planck Institut für Festkörperforschung [Institute for Solid State Research], Stuttgart, Germany (1991-1993). O nwetara 2001 JB Wagner Award nke High Temperature Materials Division of Electrochemical Society, 2000 Coble Award from the American Ceramic Society, na 1997 TMS Robert Lansing Hardy Award. "Outstanding Women in Science lecture to feature Caltech's award-winning Haile", Indiana University website published October 19, 2010 (accessed November 16, 2010) N'afọ 2010, a kpọrọ Haile ka ọ nye nkuzi nkuzi "Ụmụ nwanyị pụtara ìhè na Sayensị" na Mahadum Indiana .  Na 2018, a họpụtara Haile ka ọ bụrụ onye otu ndị otu nyocha ihe akụrụngwa .  Haile nwetakwara ihe nrite nkuzi nkuzi MRS 2021. 

 Ndụ mbido 
A mụrụ Haile na Addis Ababa, Etiopia  na 1966. Ezinụlọ ya gbapụrụ Etiopia n'oge ọchịchị n'etiti '70s, mgbe ndị agha nwụchiri wee gbuo nna ya bụ onye ọkọ akụkọ ihe mere eme Getachew Haile n'oge ahụ bụ onye otu nzuko omeiwu Etiopia. N'ihe dị ka afọ 10,  ezinụlọ ahụ biri na ime obodo Minnesota ebe Haile gara ụlọ akwụkwọ Preparatory Saint John (Collegeville, MN), gụsịrị akwụkwọ na 1983.

Ọ nwetara nzere bachelọ sayensị na PhD na Massachusetts Institute of Technology . O nwekwara Master of Science na Mahadum California, Berkeley . Ndụmọdụ Bernhardt J. Wuensch, ya PhD tesis bụ isiokwu "Synthesis, crystal Ọdịdị na ionic conductivity nke ụfọdụ alkali obere ụwa silicate." 

Haile nọrọ afọ atọ dị ka osote prọfesọ na Mahadum Washington, Seattle . Ọ sonyeere ngalaba Caltech na 1996, ebe ọ rụrụ ọrụ afọ 18 tupu ọ kwaga Mahadum Northwwest na 2015. Na Northwwest, Haile bụ Walter P. Murphy Prọfesọ nke Science Materials Science and Engineering na Prọfesọ nke Physics etinyere .

 Ionic steeti siri ike 
Ụlọ nyocha Haile gbadoro ụkwụ na ntụgharị ionic na ihe siri ike. Ebumnobi ya bụ ịghọta usoro na-achịkwa ụgbọ njem ion na itinye nghọta ahụ na mmepe nke electrolytes siri ike dị elu na ngwaọrụ electrochemical siri ike. Ngwa nke ndị na-eduzi ion ngwa ngwa gụnyere batrị, sensọ, nfuli ion, na mkpụrụ ndụ mmanụ ụgbọala . Nke ikpeazụ bụ nchegbu ya karịsịa.

Ndị otu ya na-enyocha proton na-eduzi ogige acid siri ike, proton na-eduzi perovskites, ikuku oxygen- na electron na-eduzi perovskites, oxygen na-eduzi oxides, na alkali -conducting silicates . Usoro ọkọlọtọ otu maka njirimara nke akụrụngwa eletrik bụ AC impedance spectroscopy . Ionic conductivity na-ejikọta chiri anya na nhazi kristal nke na mgbanwe nhazi na nhazi siri ike. Uto kristal, mkpebi nhazi site na X-ray na neutron diffraction, na nyocha nke okpomọkụ bụkwa akụkụ dị mkpa nke nyocha Dr. Haile.
