Abstract: C1.00085 : Differential dynamic optical microscopy for the characterization of soft matter: liquid crystal dynamics, volume phase transition of hydrogels, and phase transition of binary mixtures
Author:
The structure and dynamics of soft matter were studied by
differential
dynamic optical microscopy. One can retrieve q-space information
through
image processing and Fourier analysis, even when the feature
sizes in real
space image are too small to be resolved or even visible in an
optical
microscope. The temporal sequence of real space images were Fourier
transformed, and analyzed for the temporal and spatial
fluctuations of power
spectrum. Here, we present the results on liquid crystal dynamics
and their
elastic properties, volume phase transition of hydrogels when their
dimensions are sub-micron, and critical opalescence of binary
mixtures
(water/2,6-lutidine).
