Summary: The study investigates the out-of-equilibrium phase behavior of charged colloids under external oscillatory shear using non-equilibrium Brownian dynamics simulations. It reveals the formation of a twinned face-centered-cubic phase and a martensitic transition to a body-centered-cubic crystal in a specific range of maximum strain amplitude, along with the presence of a sliding layer phase and a string phase.

Summary: This paper explores alternative methods for estimating the mixing and compaction temperatures of warm mix asphalt and polymer modified bitumen mixtures, aiming to overcome potential damages caused by implementing the classic Equiviscous procedure. By evaluating different methods, the determined mixing and compaction temperatures were used to measure the mechanical properties of asphalt mixtures.

Summary: We studied the rheological properties of colloidal suspensions based on alumina nanofibers (ANF) with a mass fraction of 0.125-2 wt%. It was found that ANF suspensions exhibit high colloidal stability and have a significant impact on shear viscosity. Non-Newtonian behavior was observed in suspensions with an ANF mass fraction of 0.5 wt%. The results suggest that ANF can be a promising fibrous additive for optimizing the rheological properties of suspensions for various technical purposes.

Summary: This review discusses various studies on shear-induced structure transformation in complex liquids, showing that shearing can lead to the creation of inhomogeneities which may result in phase separation or the formation of new phases. The effects of diffusion-induced phase separation and phase transitions driven by deformation are explored, emphasizing the appearance of regular structures in systems coexisting in different concentrations or phase states.

Summary: In this study, we investigated the effects of salt addition and homogenization speed on the yield and aggregation characteristics of gluten fractions separated through a laboratory-scale batter procedure. The results showed that the gluten yield was correlated with A-starch yield and increased with salt concentration and homogenization rate. Addition of salt and increasing the homogenization rate enhanced the hydration of gluten and reduced its surface hydrophobicity. The water-binding capacity of gluten, A- and B-starch granules played a role in the centrifugal separation process.

Summary: An inelastic model of non-Brownian suspension behavior based on the persistence of straining concept of Thompson and Souza Mendes (TSM model) is proposed and compared with experiments and computations in various flow conditions. The model shows good agreement in general and highlights the significant influence of interparticle friction, which has been incorporated via a bootstrap concept.

Summary: This paper investigates the mechanisms affecting viscosity in shear thickening regimes of cement pastes. The addition of microfines reduces shear thickening properties, but does not always result in a lower increase in apparent viscosity. Furthermore, the use of microfines enhances shear thickening performance in mini-slump flow. A prediction model is proposed based on particle inertia forces and friction contacts, effectively characterizing particle frictional contact interactions in shear thickening regimes.

Summary: The study compared several alternative methods for determining mixing and compaction temperatures, finding that these methods typically resulted in lower temperatures for polymer modified bitumen. Additionally, for warm mix asphalt, implementing the steady shear flow method also yielded lower temperatures compared to the standard equiviscous method.

Summary: This study demonstrates that diffusion significantly limits the measurement times of the equation of state of charge-stabilized colloidal dispersions, and presents a microfluidic chip that can measure the entire equation of state at the nanoliter scale in a few hours. Time-resolved analyses of relaxation to equilibrium in this microfluidic experiment also provide direct estimates of the collective diffusion coefficient of the dispersion in Donnan equilibrium with a salt reservoir.

Summary: This study compared the label information of TPs with different thickening agents and found that using the same descriptors for very different viscosities on labels is a problem. The research demonstrated that shear rate and alpha-SA strongly affect viscosity, but this information is often not described on the labels.

Summary: Magnetic nanoparticles couple to polymeric environments through various mechanisms, including van der Waals, steric, hydrodynamic, and electrostatic forces. This leads to interesting effects and potential applications, although the details of the coupling are often unknown. Previous work has shown that hydrodynamic coupling alone can explain observed trends in magnetic AC susceptibility spectra for spherical particles. Now, this publication focuses on the interplay of steric and hydrodynamic interactions in non-spherical particles and their coupling to a polymer suspension.
