Yield Stress Aging in Attractive Colloidal Suspensions [PDF]
Physical Review Letters, 2022 We investigate the origin of yield stress aging in semi-dense, saline, and turbid suspensions in which structural evolution is rapidly arrested by the formation of thermally irreversible roll-resisting interparticle contacts. By performing optical tweezer (OT) three-point bending tests on particle rods, we show that these contacts yield by overcoming a

Experimental study on pumping pressure of pipeline transportation of hazardous waste
矿业科学学报, 2021 Mixing hazardous waste such as distilled residue and hazardous waste sludge which are piped to cement rotary kilns for incineration is the optimal method of co-processing of hazardous waste in China.

Extrusion rheometry of collagen dough
Czech Journal of Food Sciences, 2021 Although collagen is widely used (for example, in the food industry, in the pharmaceutical industry and in biomedicine), the rheological properties of the material are not well known for high concentrations (8% collagen, 90% water).

Rheopexy and tunable yield stress of carbon black suspensions [PDF]
, 2012 We show that besides simple or thixotropic yield stress fluids there exists a third class of yield stress fluids. This is illustrated through the rheological behavior of a carbon black suspension, which is shown to exhibit a viscosity bifurcation effect ...

Portland/Sulfoaluminate Cement Blends for the Control of Early Age Hydration and Yield Stress
Buildings, 2023 Early age hydration and the rheological behavior of cement pastes are related to their reactivity. The reactivity of Ordinary Portland Cement (OPC) and calcium sulfoaluminate cement (CSA) blends, with a CSA percentage of less than 10%, are investigated ...

Magnetic field induced inversion in the effect of particle size on powder cohesiveness [PDF]
, 2010 Experimental measurements are reported on the tensile yield stress of magnetofluidized beds of fine magnetic powders operated in the cross-flow configuration. In the absence of externally applied magnetic field the yield stress of the powder depends on

Avalanche Behavior in Yield Stress Fluids [PDF]
Physical Review Letters, 2002 We show that, above a critical stress, typical yield stress fluids (gels and clay suspensions) and soft glassy materials (colloidal glasses) start flowing abruptly and subsequently accelerate, leading to avalanches that are remarkably similar to those of granular materials.

Frontiers in Materials, 2019 The increase of the yield stress vs. the magnetic field is the most important quantity characterizing the efficiency of a magnetorheological suspension. The theory based on the formation of columnar aggregates predicts a linear variation with the volume ...

Analysis of the flowability of cohesive powders using Distinct Element Method [PDF]
, 2005 Computer simulations using Distinct Element Method (DEM) have been carried out to investigate the effect of cohesion on the flowability of polydisperse particulate systems. For this purpose, two assemblies with different values of surface energy and made
