Yielding and bifurcated aging in nanofibrillar networks [PDF]
Phys. Rev. Materials 4, 102601 (2020), 2020 The yielding of disordered materials is a complex transition involving significant changes of the material's microstructure and dynamics. After yielding, many soft materials recover their quiescent properties over time as they age. There remains, however, a lack of understanding of the nature of this recovery. Here, we elucidate the mechanisms by which

Boiling of an emulsion in a yield stress fluid [PDF]
Physical Review E, 2010 We report the boiling behavior of pentane emulsified in a yield stress fluid, a colloidal clay (Laponite) suspension. We have observed that a superheated state is easily reached: the emulsion, heated more than 50 °C above the alkane boiling point, does not boil.

Yield stress of aerated cement paste [PDF]
Cement and Concrete Research, 2020 Yield stress of aerated cement paste is studied. Samples are prepared by mixing aqueous foam with cement paste, which allows controlling bubble size, gas volume fraction and yield stress of the cement paste. Two distinct behaviors are observed depending on the surfactant used to prepare the precursor aqueous foam: (i) For a surfactant with low ...

Yield Stress Fluids Solidifying in Capillary Imbibition [PDF]
J. Fluid Mech. 996 (2024) A48, 2023 When subjected to an external stress that exceeds the yield stress ($\sigma_\mathrm{Y}$), yield stress fluids (YSFs) undergo a solid-to-liquid transition. Despite the extensive studies, there has been limited attention to the process of liquid-to-solid transition.

Adhesion of yield stress fluids [PDF]
Soft Matter, 2010 The different regimes of flow when separating two solid rough surfaces in contact via a layer of a simple yield stress fluid are identified. Generic scalings for the adhesion energy and for the geometrical characteristics of the final deposits (after separation) as a function of the initial aspect ratio of the sample are found.

The Yield Stress of Cement Pastes as Obtained by Different Rheological Approaches
Applied Rheology, 2015 Different rheological methods for yield stress estimation of cement pastes during initial hydration were used and results were compared. These methods include measuring of the hysteresis loop, flow curves (recalculated to the same time of hydration) and ...
