SUMMARY:Painting in 3D: Structural Colour in Nature - Michelle Rigozzi
DTSTART:20081117T194500Z
DTEND:20081117T210000Z
UID:TALK15040@talks.cam.ac.uk
CONTACT:David Gordon
DESCRIPTION:Peacock feathers\, opals and many butterfly wings create their
  intense iridescent colouring in a special way\, distinct from the pigment
 s that typically colour the things around us. Nature has found ways of cra
 fting delicate nanostructures that interact with light to produce colours 
 that are not only brighter but can also change when seen from different an
 gles. These structures control the flow of light and have numerous technol
 ogical applications. However\, some of these naturally occurring structure
 s are so intricate that we do not yet know how to build them synthetically
 . This talk will give an introduction to where structural colour appears i
 n Nature\, as well as what can be learned from the way such nanostructures
  form.\n\nBio: Michelle Rigozzi is a PhD candidate at Pembroke College. A 
 graduate of Physics and Mathematics from the University of Sydney\, Austra
 lia\, she undertook a summer placement at the Natural History Museum in Lo
 ndon\, investigating the breadth of mechanisms that produce structural col
 our. Her undergraduate dissertations then focused on modelling the mechani
 cs and self-assembly of these natural photonic structures. Her PhD researc
 h is also in biophysics\, but she now models the mechanisms used by cells 
 to detect their mechanical environment.
