abstract = {An X-ray flexure-based microgap rheometer (X-FMR) has been
designed for combining rheology and in situ small-angle
X-ray scattering from the vorticity plane. The gap distance
can be varied continuously from 500 μm down to several μm,
which provides the unique possibility to generate a strong
confinement for many complex fluids. A singular advantage of
this setup is the possibility to directly probe the
vorticity direction of the flow field with a microfocus
X-ray beam and to probe the structural response of the fluid
to combined shear and confinement in the vorticity plane.
The sliding-plate setup operates over a wide range of shear
rates of γ̇ = 10−3–103 s−1 and strains in the range
of 10−4–102. The flexure-based bearing maintains the
plate parallelism within 10−5 rad. The X-FMR requires very
small sample volumes on the order of 10 μl. The
applicability of the device is demonstrated here with
limited examples of a nematic suspension of fd virus (rods),
and a crystalline suspension containing sterically
stabilized polystyrene-butylacrylate latex particles.},
