SUMMARY:MSE Seminar: "Atomic Structure Insights for Advancing Energy Storag
 e and Electronic Materials"
DESCRIPTION:Abstract\nAs batteries are employed in larger numbers and for i
 ncreasingly diverse applications\, there is a need for electrode materials
  with improved safety\, availability\, and cost relative to those in comme
 rcial devices. We support the identification of alternative materials by p
 roviding insights into the formation\, stability\, and cycling behavior of
  Co- and Ni-free electrode materials\, as well as how to tune Li-ion trans
 port pathways through composition and processing. In studying early transi
 tion metal oxides for fast cycling and cation-disordered rocksalt oxide el
 ectrode materials\, we identify both average and local structural changes 
 that influence battery cycling behavior.\nThe local structure methods we u
 se to study battery materials\, particularly pair distribution function an
 alysis\, are well-established for powdered materials but are not easily ap
 plicable to other sample forms\, such as thin films. To gain an essential 
 understanding of amorphous and nanocrystalline thin films for electronic a
 pplications\, we have developed a program to enable pair distribution func
 tion analysis of films on single crystal substrates. This program leverage
 s machine learning and the inherent differences in scattering from polycry
 stalline films and single-crystal substrates. We continue to refine this a
 pproach to improve efficiency and fidelity\, as well as to probe thinner f
 ilms.\nBio\nMegan Butala\, Ph.D.\nAssistant Professor\, Department of Mate
 rials Science &amp\; Engineering\nUniversity of Florida\nDr. Megan Butala
  (she/her) is an Assistant Professor of Materials Science and Engineering
  at the University of Florida (UF). The Butala Research Group focuses on m
 aterial selection and design by elucidating the relationships between comp
 osition\, processing\, atomic structure\, and functional properties\, as w
 ell as their evolution during dynamic processes. The group is particularly
  interested in materials for energy storage\, information storage\, and co
 mputing.\nBefore joining the faculty at UF\, Megan completed her Ph.D. in 
 Materials at the University of California\, Santa Barbara\, where she inve
 stigated the atomic structure and mesoscale origins of high-energy Li-ion 
 battery electrodes in Ram Seshadri’s group. Subsequently\, she furthered
  her expertise in solid-state materials chemistry and atomic structure ana
 lysis as a National Research Council postdoctoral fellow at the National I
 nstitute of Standards and Technology.\nMegan’s work was recently recogni
 zed by an NSF CAREER award\, which will begin on February 1\, 2025.
