DESCRIPTION:Prof. Marie-Laure Bocquet\, CNRS\, Chemistry Laboratory\, ENS 
 Paris\nAbstract:\nGraphene is an attractive candidate for carbon-based ele
 ctronic devices. However the absence of band gap is a major hindrance for 
 this promising application. There is a need to develop facile routes for e
 ngineering the band gap via molecular functionalizations. The challenge re
 sides in the fact that graphene is assumed to be chemically inert. [1]\nIn
  this talk I will mitigate this assumption and show using state-of-the-art
  quantum chemistry how graphene can properly react with molecules under mi
 ld conditions\, first in UHV on a specific UHV graphene/metal interface [2
 ] and seconds in alkaline water solvent .[3-4]\n \nReferences:\n[1] A. Ef

 le Normale Supérieure de Lyon in 1993\, performed her phD about the simul
 ation of STM images under the supervision of Philippe Sautet in the Chemis
 try Laboratory of ENS Lyon. She is now a Director of Research at the CNRS 
 in the Chemistry Laboratory of ENS Paris\, where her research interests ar
 e focused on the elucidation of chemical processes occuring at metallic\, 
 oxide or graphenic surfaces either in vacuum or in water media . They are 
 mainly driven by high-resolution data acquired with a Scanning Tunneling M
 icroscope STM or nanofluidic measurements in collaborative experimental gr
 oups.\nIn 2007 she held an one-year Humboldt Fellowship to study (in colla
 boration with Munich) the STM & theory of epitaxial graphene on metal surf
 aces. In 2013 she took a year sabbatical stay in the CNRS-MIT joint lab\, 
 Cambridge USA in 2013 working on atomistic models of shale gas.\nHer scien
 tific production consists of 79 publications in peer-reviewed journals (in
 cluding Nature Chemistry\, PRL\, JACS and Angewandte)\, 26 Invited Talks i
 n international conferences and 27 Invited Seminars in international insti
 tutions.
