Description:About the Seminar\n\nMost plasmonic metals studied to date are 
 composed of either Cu\, Ag\, and Au. The former two can pose significant c
 hallenges related to oxidation\, the latter is often perceived as cost-pro
 hibitive\, and all three are rare. Recently\, much attention has been focu
 sed on earth-abundant Al\, which is an excellent plasmonic in the UV. This
  talk will briefly discuss colloidal Al nanoparticles as a plasmonic mater
 ial\, then report results on a new composition: magnesium. Mg nanoparticle
 s are remarkably active plasmonics across the UV\, Vis and NIR\, as shown 
 optically and with STEM-EELS. Surprisingly\, they are stable in air for we
 eks owing to a self-limiting oxide layer. Colloidal Mg has potential on it
 s own as a plasmonic structure\, and can also be used as a scaffold for ad
 ditional surface chemistry\, sensing\, and hybrid photocatalysts.\n\n&nbsp
 \;\n\nAbout the Speaker\n\nEmilie Ringe earned her B.A./M.S. summa cum lau
 de in chemistry\, then Ph.D. in chemistry and materials science at Northwe
 stern University in 2012. She became the Gott Research Fellow at Trinity H
 all as well as a Newton International Research Fellow (Royal Society) in t
 he Electron Microscopy group in the Materials Science and Metallurgy Depar
 tment at the University of Cambridge\, UK. In 2014\, she was hired as an a
 ssistant professor at Rice University\, where she established the Electron
  Microscopy Center and received funding from the Air Force Office of Scien
 tific Research (YIP)\, NSF\, ACR-PRF\, 3M\, and the US/Israel Binational S
 cience Foundation.\nIn 2018\, she moved to England to take up a lectureshi
 p in multi-scale\, multi-dimensional imaging of natural and synthetic mate
 rials at the University of Cambridge\, joint between the Department of Mat
 erials Science and Metallurgy and the Department of Earth Sciences. She re
 ceived an ERC Starting grant (1.6M Euros) to pursue her studies of Earth-a
 bundant plasmonics. She has been elected fellow of Gonville &amp\; Caius C
 ollege\, is an associate member of the Royal Society of Chemistry\, and se
 rves on the editorial board of Materials Chemistry Frontiers. 4:00 pm
