Transient rheology of solvent-responsive complex fluids by integrating microrheology and microfluidics
A new microrheology set-up which allows us to quantitatively measure the transient rheological properties of solvent-responsive complex fluids was constructed by integrating particle trackingExpand

Shear-induced diffusion and rheology of noncolloidal suspensions: Time scales and particle displacements
The shear-induced self-diffusion and rheology of concentrated suspensions of noncolloidal hard spheres have been studied experimentally. The combined results provide an interesting physical picture.Expand

Measuring shear-induced self-diffusion in a counterrotating geometry.
The novel correlation method to measure shear-induced self-diffusion in concentrated suspensions of noncolloidal hard spheres which we developed recently [J. Fluid Mech. 375, 297 (1998)] has beenExpand

Microrheological detection of protein unfolding.
We apply passive probes to protein solutions and evaluate the viscous response to folding and unfolding, allowing us to accurately quantify both the thermodynamics of protein folding and theExpand

Dynamics of unentangled cyclic and linear poly(oxyethylene) melts
Abstract Monodisperse low-molecular-weight (400–1500 g/mol) cyclic poly(oxyethylene)s (CPOE)s were synthesized from linear dihydroxy-terminated poly(oxyethylene)s (LPOE)s. The self-diffusion, NMRExpand

Microscopic structural relaxation in a sheared supercooled colloidal liquid.
The rheology of dense amorphous materials under large shear strain is not fully understood, partly due to the difficulty of directly viewing the microscopic details of such materials. We use aExpand

Linear viscoelastic behavior of aggregated colloidal dispersions
The viscoelastic behavior of a depletion-flocculated dispersion of colloidal spheres is investigated at different volume fractions of the spheres, using a controlled stress and a dynamic rheometer.Expand

Modeling effects of oxygen inhibition in mask‐based stereolithography
Purpose – The purpose of this paper is to present a model that can be used to simulate the photopolymerization process in micro‐stereolithography (SL) in order to predict the shape of the curedExpand

Phase behavior in highly concentrated assemblies of microgels with soft repulsive interaction potentials.
Microgel particles with a soft repulsive interaction potential are investigated with particle tracking methods to study the phase behavior of soft-sphere systems. The use ofExpand

Tunable attractive and repulsive interactions between pH-responsive microgels
We report direct measurements of the pairwise interparticle potential between poly(N-isopropylacrylamide-co-acrylic acid) (pNIPAm-co-AAc) colloidal microgels as a function of pH, as determinedExpand
