Description:About the Seminar:\n\nOver the last two decades\, we have witne
 ssed a paradigm change in the way we characterize materials using electron
  microscopy. This latest revolution in resolution began in the late 1990â€
 ™s with the first successful implementation of an objective lens aberratio
 n corrector\, which improved the spatial resolution of transmission (TEM) 
 and scanning transmission electron microscopy (STEM) by more than a factor
  of two to below 50 pm. These developments were followed by faster\, more 
 sensitive direct electron (CMOS) detectors\, monochromated electron source
 s for electron spectroscopy and\, most recently\, magnetic field-free lens
 es. As the result of these transformative discoveries\, we are now able to
  study biological and condensed matter materials with unprecedented resolu
 tion\, sensitivity and precision. While spatial and energy resolutions bet
 ter than 60 pm and 10 meV have been reported\, aberration-corrected TEM ha
 s also enabled a large variety of in-situ experiments at close to atomic r
 esolution. This has enabled us to correlate the atomic structure with i) t
 he properties of multi-valent ion intercalation cathodes\, ii) the dynamic
 s of vacancies in thin films and iii) thermal response of 2D materials\, t
 o only mention a few examples.\n\nBio\n\nDr. Robert F. Klie is a Full Prof
 essor of Physics at the University of Illinois at Chicago and a world lead
 er in the in-situ characterization of complex materials interfaces. He foc
 uses on aberration-corrected imaging and spectroscopy of photovoltaic and 
 battery cathode materials at the atomic scale using scanning transmission 
 electron microscopy (STEM). In recent years. Dr. Klie has pioneered novel 
 approaches to studying water\, biological systems and solid-liquid interfa
 ces using graphene liquid cells and ultra-high resolution electron energy-
 loss spectroscopy (EELS). Dr. Klie has published over 180 peer-reviewed pa
 pers with more than 5\,400 citations\, given more than 80 invited talks at
  prestigious international conferences\, and has an h-index of 38. His sci
 entific achievements have been recognized by a number of prestigious award
 s\, including the Brookhaven Goldhaber Distinguished Fellowship and the Un
 iversity of Illinois Researcher of the Year award. Dr. Klie is also in cha
 rge of the Functional and Regenerative Materials Initiative at the Univers
 ity of Illinois\, bringing together scientists from the medical field and 
 the areas of materials science and engineering to develop multi-modal appr
 oaches for in-vivo sensors or tissue regeneration. 4:00 pm
