According to statistical mechanics, these will have a gravitational sedimentation profile extending over 20-50 microns. The Brownian motion should be visible in 3D with the phase contrast microscope we are devoping for 34-ID-C. We would like to measure this as a function of the viscosity of the supporting medium in glycerol-water mixtures, as a function of temperature. equipment_required: X-ray microscope experiment: Microscopy of sedimentation for Nanocubes foreign_nationals: hazards: none instrument: 34ID-C coherent instrument_other: minimumdays: 4 name: Ian Robinson new_request: ON nonmembers: unacceptable_dates: Must coordinate with Christoph Rau's availability.
