Multiple particle tracking microrheology measured using bi-disperse probe diameters

03-Jul-2018 | Matthew Wehrman; Seth Lindberg; Kelly M Schultz, Soft Matter, 2018

Multiple particle tracking microrheology (MPT) is a powerful tool for quantitatively characterizing rheological properties of soft matter. Traditionally, MPT uses a single particle size to characterize rheological properties. But in complex systems, MPT measurements with a single size particle ...

Microrheology of DNA Hydrogels Gelling and Melting On Cooling

26-Jun-2018 | Javier Fernandez-Castanon; Silvio Bianchi; Filippo Saglimbeni; Roberto Di Leonardo; Francesco Sciortino, Soft Matter, 2018

We present a systematic characterisation by means of dynamic light scattering and multiple particle tracking techniques of the viscosity and of the linear viscoelastic moduli, G'(ω) and G''(ω), for two different DNA hydrogels. These thermoreversible systems are composed by tetravalent DNA-made ...

Rheology of phosphonium ionic liquids: a molecular dynamics and experimental study

31-May-2018 | Sten Sarman; Yong-Lei Wang; Patrick Rohlmann; Sergei Glavatskih; Aatto Laaksonen, Physical Chemistry Chemical Physics, 2018

We have studied the rheological behavior of the ionic liquid trihexyl(tetradecyl)phosphonium bis(mandelato)borate, [P66614][BMB], and compared it with that of another ionic liquid, namely trihexyl(tetradecyl)phosphonium chloride, [P66614][Cl]. The non-halogenated [P66614][BMB] has been selected ...

Understanding the Surface Properties and Rheology of Silica Suspension Mediated by Comb-type Poly (Acrylic Acid)/Poly (Ethylene Oxide) (PAA/PEO) Copolymer: Effect of Salinity

30-May-2018 | Dingzheng Yang; Bin Yan; Xiang Li; Haolan Xu; Xiaogang Wang; Hongbo Zeng, Soft Matter, 2018

Understanding the surface properties and rheology of colloidal suspensions in the presence of polymer additives with high salinity is of great importance in formulating construction materials, and optimizing process conditions in mining and petroleum industry. In this work, the surface properties ...

Branching and alignment in reverse worm-like micelles studied with simultaneous dielectric spectroscopy and RheoSANS

30-May-2018 | John K. Riley; Jeffrey J. Richards; Norman J. Wagner; Paul D. Butler, Soft Matter, 2018

Topology and branching play an important but poorly understood role in controlling the mechanical and flow properties of worm-like micelles (WLMs). To address the challenge of characterizing branching during flow of WLMs, dielectric spectroscopy, rheology, and small-angle neutron scattering ...

Nonlinear chiral rheology of phospholipid monolayers

28-May-2018 | KyuHan Kim; Siyoung Q. Choi; Joseph A. Zasadzinski; Todd M. Squires, Soft Matter, 2018

Microbutton rheometry reveals that the chiral morphology of dipalmitoylphosphatidylcholine (DPPC) monolayers imparts a chiral nonlinear rheological response. The nonlinear elastic modulus and yield stress of DPPC monolayers are greater when sheared clockwise (C), against the natural winding ...

Polyelectrolyte scaling laws for microgel yielding near jamming

28-May-2018 | Tapomoy Bhattacharjee; Christopher P. Kabb; Christopher S. O’Bryan; Juan M. Urueña; Brent S. Sumerlin; W. Grego ..., Soft Matter, 2018

Micro-scale hydrogel particles, known as microgels, are used in industry to control the rheology of numerous different products, and are also used in experimental research to study the origins of jamming and glassy behavior in soft-sphere model systems. At the macro-scale, the rheological ...
