Orientation |
Nanoparticles can provide useful building
blocks in many structural and functional assemblies. One of the particular
challenges is to synthesise nanoparticles with defined chemistry, shape and
size with functional elements at their surfaces to enable the assembly
process. A second important
issue is to measure these properties to ensure that the particles are
suitable for their purpose. In the latter area, there is an absence of
knowledge in how to interpret data and which methods to use because most
methods assume that particles are spherical. There is a pressing need for
well characterised materials of known shape and chemistry to develop new
models for data interpretation. |
How |
We will concentrate on gold nanorods of
defined shape, measured using electron microscopy, and examine the influence
of these shapes upon data acquired using light scattering, optical
absorption, sedimentation and X-ray photoelectron spectroscopy. The gold
particles will be coated with organic materials of well-defined chemistries,
including self-assembled monolayers of thiols. |
What |
The study will be
conducted in a modern laboratory at The Royal Institution of Great Britain,
which has a long and distinguished 200 year history, including the award of
14 Nobel Prizes, the discovery of 10 elements, and the invention of the
electric generator, to name just a few of many seminal achievements. For more details, you can go to Prof
