The development of advanced creep constitutive equations for high chromium steel P91 at low stress range

, 2013
Diffusion dominates the creep deformation at low stress range for high chromium steel P91. Brittle creep fracture is caused by cavity nucleation, growth and coalescence of cavities and large precipitates (Laves phase and M23C6) at grain boundary under ...

Tensile creep behaviour of as-cast Mg-4Al-4RE (2.7La-1.3Ce) alloy

Next Materials
The Mg-4Al-2.7La-1.3Ce alloy was synthesized by melting in a resistance furnace at 750°C under a protective atmosphere of 98 % argon and 2 % SF6 to prevent oxidation.

GPR124 Alleviates Blood–Brain Barrier Disruption by Enhancing Microvascular Endothelial Function after Traumatic Brain Injury

Advanced Science, EarlyView.
Our study reveals the protective role of GPR124 in maintaining BBB integrity and promoting neurological recovery following TBI. It makes a significant contribution by uncovering a novel molecular interaction between GPR124 and FGFBP1 and linking this to activation of the Wnt/β‐catenin signaling pathway in vascular repair mechanisms.
