Description:About the Seminar:\nThe programmed assembly of nanoscale buildi
 ng blocks offers exciting new avenues to create materials in which structu
 re and functions can be chemically designed and tuned. In this context\, t
 he synthesis of inorganic molecular clusters with atomically defined struc
 tures\, compositions and surface chemistry provides a rich family of funct
 ional building elements. This presentation will describe our efforts to as
 semble such “designer atoms” into a variety of hierarchical structures
  in which the preformed clusters emulate the role of atoms in traditional 
 “atomic” solids. The resulting materials offer a unique opportunity to
  combine programmable building blocks and atomic precision. As such\, they
  bridge traditional crystalline semiconductors\, molecular solids\, and na
 nocrystal arrays by synergizing some of their most attractive features. Re
 cent synthetic advances to develop this concept into a “modular” platf
 orm for materials design will be presented\, along with some of the unique
  collective material properties (magnetic\, optical\, electrical and therm
 al transport) that emerge as a result of the atomic precision of the cryst
 al lattice and the specific interactions between the building blocks. The 
 presentation will conclude with an assessment of future developments.\nAbo
 ut the Speaker:\nXavier Roy received a B.Eng. (2002) and a Master of Appli
 ed Science (2005) in Chemical Engineering from Ecole Polytechnique of Mont
 real\, performing research under the guidance of Prof. Basil Favis. He ear
 ned his Ph.D. in Chemistry with Prof. Mark MacLachlan at the University of
  British Columbia in 2011\, working as an NSERC Alexander Graham Bell Scho
 lar. He went on to do postdoctoral research as a Canada NSERC Postdoctoral
  Fellow with Prof. Colin Nuckolls at Columbia University from 2011 to 2013
 . He joined the Columbia University Faculty in 2013 as an Assistant Profes
 sor of Chemistry\, and was promoted to the rank of Associate Professor in 
 2018. 4:00 pm
