DESCRIPTION:Prof. Vasiliki Tileli - INE EPFL\nThe field of in-situ electr
 on microscopy for probing the evolution of nanomaterials during electroche
 mical process has quickly developed in recent years due to the advancement
 s of specialized apparatus. The technique enables observations of dynamic
  changes associated with morphological\, microstructural\, and chemical e
 volution of surfaces and interfaces when exposed to appropriate stimuli an
 d has the potential to enhance our know-how of the processes that take pla
 ce during device operation. During this talk\, I will discuss the developm
 ent and application of in-situ nanoanalytical transmission electron micros
 copy techniques on three distinctive electrochemical processes: charge/dis
 charge cycling of layered oxide cathodes for lithium-ion batteries\, cycli
 ng of Co-based oxides for oxygen evolution reaction\, and probing of Cu na
 nocatalysts during the first stages of CO2 reduction reaction. The challe
 nges involved with performing such experiments will also be discussed.\n\n
 About the speaker\nVaso Tileli is currently an Assistant Professor at the 
 Institute of Materials at EPFL working on the fundamental aspects of nanos
 cale physicochemical phenomena in functional materials revealed by in sit
 u electron microscopy techniques. She received her PhD from the College o
 f Nanoscale Science and Engineering at University at Albany\, SUNY NY\, wh
 ile working on electron beam/specimen interactions in electromagnetic fiel
 ds in the presence of gases. She joined as a Marie Curie Intra-European Fe
 llow the Department of Materials at Imperial College London for the develo
 pment and application of advanced microscopy techniques for functional oxi
 de materials and she spent time at the Department of Physics and Astronomy
  at University College London working on electron characterization of hybr
 id and/or 2D structures. \n
