Ductile B2 Intermetallics‐Driven Strength‐Ductility Synergy in Heterolaminated Multi‐Principal Element Alloys

Advanced Science, EarlyView.
Intrinsic phase toughening transforms a brittle B2 intermetallic into a plastically deformable, load‐bearing phase, while a heterogeneous laminated architecture suppresses strain localization and interface cracking. The synergy between ductile intermetallics and mesoscale heterogeneity establishes a general design strategy for breaking the long ...

Unveiling the Ultralow Thermal Conductivity of Hybrid Perovskites

Advanced Science, EarlyView.
In hybrid perovskites, thermal energy flows through lattice vibrations of the framework (48%–65%) and organic molecules (35%–52%). When the disorder introduced by organic molecules is excluded, the temperature dependence of the vibrational thermal conductivity results from the lattice framework transits from ∼T0 to ∼T−1, and the value doubles at room ...

The Nonlinear Vibration Absorber for Mitigating Torsional Vibrations

From causing mild inconveniences to catastrophic failures, vibration affects all structural and mechanical components. The situation becomes especially critical when the structure is subjected to an exciting force that induces resonance. Industry trends towards lightweight construction compounds this issue by lowering the resonance frequency .
