Description:About the Speaker:\n\nDr Asaph Widmer-Cooper is an Associate Pr
 ofessor in the School of Chemistry at the University of Sydney\, a Chief I
 nvestigator of the Centre of Excellence in Exciton Science\, and a member 
 of the University of Sydney Nano Institute. His research focuses on the ap
 plication of computer simulations to understand how nanomaterials form and
  behave. This includes work on nanoparticle interactions and assembly\, th
 e structure and dynamics of complex fluids\, crystal nucleation and growth
 \, and the design of new materials for harnessing solar energy.\n\nAbout t
 he Seminar: \n\nOne of the biggest challenges of the 21st century will be
  our transition away from a reliance on fossil fuels to power the world. T
 his will require better methods of generating and transforming energy\, in
 volving materials with clever design of light-matter interactions. Equally
  important is to make these materials via scalable\, energy-efficient proc
 esses\, so that new technologies can be deployed at scale with low embodie
 d energy. This\, in turn\, requires exquisite control over the spontaneous
 \, bottom-up organisation of atoms\, molecules and nanoparticles into orde
 red structures near ambient conditions.\n\nI will discuss how we are addre
 ssing this problem\, in collaboration with experimental partners\, via the
  use of theoretical models and computer simulations. This will include exp
 lanation of how surface ligands influence the colloidal stability\, shape 
 and optical properties of nanoparticles [1-4]\, how such particles can be 
 assembled into ordered structures [5-6]\, and how the microstructure of pr
 intable ionic semiconductors depends on their interaction with light and h
 eat [7\,8]. A recurrent theme in this work is the crucial role of nanoscal
 e strain in regulating materials properties\, including chirality. 4:00 pm
