Harnessing Phase Separation for the Development of High‐Performance Hydrogels
Advanced Science, EarlyView.ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...

Brittle-to-ductile transition in fracture of few-layered black phosphorus ribbons under uniaxial stretching [PDF]
, 2018 Owing to excellent electrical properties, few-layered black phosphorene (BP) ribbons will be wide used in nano-electro-mechanical systems. Before acting as a component in the nanosystem, they should be fabricated successfully.

Advanced Science, EarlyView.Precipitation‐modulated recrystallization enables a programmable bimodal harmonic architecture in a high‐entropy alloy, delivering 1–2 GPa yield strength with >10% ductility from −196 °C to 700 °C. The resulting broad‐temperature robustness arises from the synergy of dual‐mode nanoprecipitation, harmonic core–shell topology, and temperature‐adaptive ...

Advanced Science, EarlyView.Hierarchical PP–LSR107–BaTiO3 nanocomposite films are fabricated by one‐step extrusion and stretching for roll‐to‐roll manufacture, combining high energy storage and processing flexibility. LSR107 surrounds BaTiO3‐rich regions, locating amorphous PP, decreasing defects, and introducing deep traps that homogenize the electric field and suppress charge ...

The slip-rate, state-, temperature-, and normal-stress-dependence of fault frictionKey points
Earthquake ScienceThe mechanics of slow-slip events and earthquakes is controlled by the constitutive behavior of rocks in active fault zones, which is sensitive to many factors encompassing lithology, temperature, confining and pore-fluid pressure, and slip-rate, among ...
