Mechanical properties and energy absorption of bio-inspired hierarchical circular honeycomb

Ngoc San Ha et al.

Summary: This study proposed a new bio-inspired hierarchical circular honeycomb (BHCH) with excellent energy absorption capacity. The experimental results showed that BHCH outperformed the conventional circular honeycomb in terms of energy absorption and had significantly higher relative stiffness, strength, and energy absorption than other cellular structures. The theoretical model analysis further demonstrated the enhanced energy absorption mechanism of BHCH.

Layer-by-layer stacking, low-temperature welding strategy to effectively recycle biaxially-oriented polypropylene film waste

Qi Wu et al.

Summary: High-value recycling and reuse of plastic products are crucial in addressing global plastic pollution. This study proposes an innovative and efficient method for recycling biaxially oriented polypropylene (BOPP) film waste, achieving high strength and toughness through temperature-sensitive interfacial diffusion and orientation retention mechanisms. Furthermore, the use of supercritical CO2 foaming technology transforms the high-performance fused PP sample into lightweight and rigid foam, adding more value to the recycling process. This method is simple, scalable, economical, and can be applied to other biaxially oriented films, setting a good example for achieving a green and low-carbon life.

Ultrahigh-Aspect-Ratio Boron Nitride Nanosheets Leading to Superhigh In-Plane Thermal Conductivity of Foldable Heat Spreader

Qingwei Yan et al.

Summary: A rapid and high-yield method based on a microfluidization technique is developed to obtain exfoliated BNNS with a record high aspect ratio of approximate to 1500 and low degree of defects. The composite film made of BNNS and poly(vinyl alcohol) (PVA) matrix exhibits an in-plane thermal conductivity of 67.6 W m(-1) K-1 at a BNNS loading of 83 wt %, leading to a record high value of thermal conductivity enhancement (approximate to 35,500). This provides a practical route to produce electrically insulating polymer composites with high thermal conductivity for thermal management applications in modern electronic devices.
