On the Mechanical and Thermal Behavior of PLA, PBAT, and PHBV‐Based Ternary Blends and the Effect of Short Flax Fibers as Reinforcing Agents

Polymer Composites, EarlyView.
Preparation and testing of biodegradable polymer ternary blends and composites with short flax fibres. ABSTRACT Bioplastics offer environmental benefits but they are costly and exhibit lower mechanical and thermal performance compared to fossil‐based counterparts. Poly(butylene adipate‐co‐terephthalate) (PBAT) exhibits high ductility but relatively low

Experiments on High-Temperature Irradiation of Li₂ZrO₃/MgLi₂ZrO₄ Ceramics by He²⁺ Ions

Ceramics
The key objective of this study is to determine the effect of interphase boundaries, the formation of which is caused by the variation of Li2ZrO3/MgLi2ZrO4 phases in lithium-containing ceramics based on lithium metazirconate, on the resistance to near ...

Aggregation‐induced enhanced emission for quantification of recycled content in automotive plastics

Polymer International, EarlyView.
Quantifying recycled content in four automotive plastics using aggregation‐induced enhanced emission showed that performance was highly dependent on both polymer and additive chemistries. Abstract The use of plastics in the automotive industry is increasing due to their versatility, light weight and affordability.

Transforming Grain-Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy. [PDF]

Adv Sci (Weinh)
By engineering graded BCC/L12 interfaces, brittle precipitates in a complex concentrated alloy enable sequential deformation, realizing gigapascal strength with >20% elongation to solve the strength‐ductility trade‐off. ABSTRACT Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack ...

Embrittlement behaviour of metal additive-manufactured high-entropy alloy components under gaseous and electrochemical hydrogen charging

Journal of Materials Research and Technology
Embrittlement is an environmentally induced fracture that primarily affects metallic materials. This phenomenon occurs when hydrogen is absorbed on the metal surface and penetrates to the core, followed by degrading the mechanical properties in a ...
