Query: Slow dynamics in cylindrically confined colloidal suspensions   We study bidisperse colloidal suspensions confined within glass
microcapillary tubes to model the glass transition in confined cylindrical
geometries. We use high speed three-dimensional confocal microscopy to observe
particle motions for a wide range of volume fractions and tube radii. Holding
volume fraction constant, we find that particles move slower in thinner tubes.
The tube walls induce a gradient in particle mobility: particles move
substantially slower near the walls. This suggests that the confinement-induced
glassiness may be due to an interfacial effect.
