Enhanced Superconductivity in X4H15 Compounds via Hole‐Doping at Ambient Pressure

open access: yesAdvanced Science, EarlyView.
Hole doping in X4H15 hydrides significantly enhances superconductivity, with X3 + compounds reaching Tc values near 50 K due to strong electron–phonon coupling. A viable route is proposed by doping thermodynamically unstable X43+H${\rm X}^{3+}_4{\rm H}$15 to control the charge‐compensated YZr3H15 compound.

Ultrahigh Strength and Exceptional Work Hardening in a Hierarchical‐Structured Alloy via Hetero‐Interface‐Mediated Twinning

open access: yesAdvanced Science, EarlyView.
This study presents a novel strategy for achieving exceptional work hardening in ultrahigh‐strength alloys by designing hierarchically heterogeneous dual‐phase (HHDP) structures, where hetero‐deformation‐induced strain gradients activate deformation twinning.
