“…This led to various, somewhat speculative, models. [90][91][92][93][94][95] Once again, here we are approaching the limit for relevantly predicting, from a microscopic approach, the liquid behaviour of a material made of a lot of elements interacting in a simple liquid.…”

Pastes are materials intermediate between solids and liquids which are of great practical interest as they keep the shape they have been given. Despite their various internal structures it is possible to draw up a generic rheophysical scheme from which one qualitatively understands, from a physical point of view, their main mechanical characteristics, i.e. solid regime, solid-liquid transition, liquid regime, thixotropy and aging. Here we review in detail these different properties as they are generally observed with most pasty materials and the attempts to describe them using microscopic structure-based theoretical models. For real systems a unified, qualitative, conceptual description is provided. For some model systems (e.g., foams, colloidal gels...) there exist consistent microscopic approaches providing quantitative relationships between rheological parameters in the solid regime and physical parameters of the system. For the liquid regime and thixotropy the situation is more complex.

“…Snoswell et al [6] have shown that heteroaggregates with controlled porosity can be prepared using microgel particles. Even though the properties of homoaggregate gels have attracted considerable interest [7,8], gelation of concentrated mixed dispersions is a relatively unexplored research area. The objectives of this paper are to investigate pH-triggered heteroaggregate formation in dilute dispersions and gelation in concentrated dispersions of poly-* Corresponding author.…”

“…The solid behavior of the yield-stress fluid under stationary conditions is associated with the formation of a three-dimensional network of chain-type silica aggregates [ 47 ]. The network is easily disrupted under the shear stress and rapidly recovered when the external loading is removed [ 48 ]. Notice that the PEO effectively enhances the stability of the yield-stress fluid to suppress the potential sedimentation during long-term storage (see Figure S1 ).…”

In contrast to ionically conductive liquids and gels, a new type of yield-stress fluid featuring reversible transitions between solid and liquid states is introduced in this study as a printable, ultrastretchable, and transparent conductor. The fluid is formulated by dispersing silica nanoparticles into the concentrated aqueous electrolyte. The as-printed features show solid-state appearances to allow facile encapsulation with elastomers. The transition into liquid-like behavior upon tensile deformations is the enabler for ultrahigh stretchability up to the fracture strain of the elastomer. Successful integrations of yield-stress fluid electrodes in highly stretchable strain sensors and light-emitting devices illustrate the practical suitability. The yield-stress fluid represents an attractive building block for stretchable electronic devices and systems in terms of giant deformability, high ionic conductivity, excellent optical transmittance, and compatibility with various elastomers.
