Embedded droplet printing in yield-stress fluids. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance Conventional microfluidic methods primarily rely on fluids that behave in simple ways, like water. Yield-stress fluids are materials that behave in a complex way, dramatically transitioning between solid-like and liquid-like behavior ...

Aspiration-assisted freeform bioprinting of prefabricated tissue spheroids in a yield-stress gel. [PDF]
Commun Phys, 2020 Bioprinting of cellular aggregates, such as tissue spheroids, to form three-dimensional (3D) complex-shaped arrangements, has posed a major challenge due to lack of robust, reproducible and practical bioprinting techniques.

2.5D printing of a yield-stress fluid. [PDF]
Sci Rep, 2023 Abstract We report on direct ink writing of a model yield-stress fluid and focus on the printability of the first layer, the one in contact with the supporting substrate. We observe a diversity of deposition morphologies that depends on a limited set of operational parameters, mainly ink flow rate, substrate speed

Granular Hydrogels as Brittle Yield Stress Fluids. [PDF]
Adv MaterABSTRACTWhile granular hydrogels are increasingly used in biomedical applications, methods to capture their rheological behavior generally consider shear-thinning and self-healing properties or produce ensemble metrics such as the dynamic moduli. Analytical approaches paired with common oscillatory shear tests can describe not only solid-like and fluid-

Local yield stress statistics in model amorphous solids [PDF]
Physical Review E, 2018 We develop and extend a method presented in [S. Patinet, D. Vandembroucq, and M. L. Falk, Phys. Rev. Lett., 117, 045501 (2016)] to compute the local yield stresses at the atomic scale in model two-dimensional Lennard-Jones glasses produced via differing ...

Stress Overshoots in Simple Yield Stress Fluids [PDF]
Physical Review Letters, 2021 Soft glassy materials such as mayonnaise, wet clays, or dense microgels display under external shear a solid-to-liquid transition. Such a shear-induced transition is often associated with a non-monotonic stress response, in the form of a stress maximum referred to as "stress overshoot".

Carbomer microgels as model yield-stress fluids
Reviews in chemical engineering, 2021 The review presents current research results for Carbopol-based microgels as yield-stress materials, covering three aspects: chemical, physical and rheological. Such a joint three-aspect study has no analog in the literature.

Acta Technica Jaurinensis, 2023 The importance of turbines in power generation cannot be overstated. While the failure in stationary plants can lead to downtime and high repair costs, its failure in mobile plants like the jet engines can be catastrophic with attendant loss of lives ...

On the “Thixotropic” Behavior of Fresh Cement Pastes
Eng, 2022 Thixotropic behavior describes a time-dependent rheological behavior characterized by reversible changes. Fresh cementitious materials often require thixotropic behavior to ensure sufficient workability and proper casting without vibration.
