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 Intermetallic Alloys
, 2002 Two distinct approaches are commonly invoked to explain the brittle to ductile transition of a material in the presence of a crack. In one approach, dislocation mobility plays the key role.

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 ...

Brittle-ductile transition in vanadium
, 1958 Mechanical tests have been made on two grades of vanadium over a range of temperatures below 25°C to establish the existence of a brittle-ductile transition and the temperature range over which it occurs. Also, the effect of small amounts of metallic and

The ductile-brittle transition of a zirconium alloy due to hydrogen
, 2010 [[abstract]]Due to the notch effect, the room temperature ductile-brittle transition was found at a lower hydrogen content between 30 and 40 ppm. A room temperature ductile-brittle transition of reduction of area was observed between 101 kPa and 1010 kPa

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 ...

Advanced Science, EarlyView.A quasi‐periodic Dart‐Kite (QDK) metastructure with a golden‐ratio‐constrained strong–weak bond network simultaneously enhances strength, toughness, and damage tolerance. Its distributed topology enables predictable, tailorable crack paths for precise fracture control and stable mechanics, demonstrating a high‐performance, controllable architecture ...

Brittle-ductile coupling : Role of ductile viscosity on brittle fracturing
, 2005 International audienceLocalized or distributed deformations in continental lithosphere are supposed to be triggered by rheological contrasts, and particularly by brittle-ductile coupling.

Advanced Science, EarlyView.Interpretable machine learning reveals how composition and processing govern the formation and microstructural burden of Fe‐rich intermetallic compounds in recycled Al–Si–Fe–Mn alloys. By separating morphology selection from morphology‐conditioned burden partitioning, this framework shows that identical Fe contents can yield different intermetallic ...
