Shear thickening characterizes liquid suspensions of particles that reversibly solidify subject to stress. Here, Comtetet al. show that shear thickening occurs at the transition from lubricated contacts to frictional contacts at a single-particle lev

Elastomers are highly valued soft materials finding many applications in the engineering and biomedical fields for their ability to stretch reversibly to large deformations. Yet their maximum extensibility is limited by the occurrence of fracture, wh

Significance Soft materials can be toughened by creating dissipative mechanisms in stretchy matrixes. Yet using them over a wide range of temperatures requires dissipative mechanisms independent of stretch rate or temperature. We show that sacrificia

Description
Tough elastomers that resist fracture at high loads are not optimum for sustaining many cycles at low loads.
Although elastomers often experience 10 to 100 million cycles before failure, there is now a limited understanding of t

A bed of deformable hairs is shown to exhibit a nonlinear response to fluid flows. The biomimetic system suggests that hair-covered surfaces in living systems may function to reduce fluid drag as a means of minimizing excessive stresses.

In many species, sucrose en route out of the leaf migrates from photosynthetically active mesophyll cells into the phloem down its concentration gradient via plasmodesmata, i.e., symplastically. In some of these plants the process is entirely passive

The slipperiness of ice is an everyday-life phenomenon which, surprisingly, remains controversial despite a long scientific history. The very small friction measured on ice is classically attributed to the presence of a thin self-lubricating film of
