The Effect of Mechanical Loading on Sprouting Angiogenesis from Engineered Macro‐vessel Model

open access: yesSmall Methods, EarlyView.
A stretchable macro‐vessel model embedded in collagen is subjected to distinct mechanical loading profiles to study sprouting angiogenesis. Finite element analysis maps strain distributions, revealing that lateral stretch enhances sprouting and alignment, while longitudinal stretch inhibits it.

Influence of Cooling Rates and Titanium Content on Hot Ductility in Niobium‐Fixed Microalloyed Steels

open access: yessteel research international, EarlyView.
The hot ductility of four microalloyed steels was examined under varying cooling rates and titanium contents. Hot tensile testing and microscopic analysis revealed that ferrite formation and TiNb(CN) precipitation critically influence hot ductility. Lower cooling rates enhance ductility by increasing ferrite thickness and modifying precipitate features,

Bioinspired Quasi‐Zero‐Stiffness Structure for Multidirectional Cushioning and Vibration Isolation

open access: yesSmall Structures, EarlyView.
Inspired by natural energy‐absorbing structures, this work proposes a bionic quasi‐zero‐stiffness (QZS) structure integrating S‐shaped and center ring cross structures. The resulting S‐shaped cubic cross center ring‐cross structure (S‐CCCRCS) design achieves QZS and superior energy absorption in all three dimensions, offering excellent multidirectional
