Addressing Oxygen Embrittlement in Additively Manufactured Titanium via Cu-Mediated Interstitial Site Engineering. [PDF]
A novel “Cu‐mediated interstitial site engineering” strategy is introduced to thermodynamically stabilize hexagonal oxygen (hex‐O) configurations in oxygen‐containing titanium alloys. The hex‐O configuration activates multiple slip systems and enhances dislocation pinning via long‐range repulsion.

Enzymatic and microbial routes to bioplastics: The green chemistry frontier of biopolymers. [PDF]
Microbial biosynthesis and engineered enzyme platforms are expanding the design space of polyhydroxyalkanoate bioplastics. By combining fermentation, PHA synthase engineering and cell‐free modular systems, tailored biodegradable polymers can be produced with tunable properties, supporting more sustainable materials and future circular bioeconomy ...

Creep fatigue behaviour and the application of damage prediction models for 2.25Cr 1Mo steel.
Experimental creep fatigue data for normalised and tempered 2.25Cr 1Mo steel at 550 °C, with strain ranges of 0.8–1.2% and dwell times of 0–120 min, was generated to assess the accuracy of five different creep-fatigue life prediction models. The accuracy

Numerical prediction of creep rupture life of ex-service and as-received grade 91 steel at 873 K [PDF]
Infallible creep rupture life prediction of high temperature steel needs long hours of robust testing over a domain of stress and temperature. A substantial amount of effort has been made to develop alternative methods to reduce the time and cost of ...

Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including
