Summary: In this study, sugar palm crystalline nanocellulose (SPCNC)-reinforced thermoplastic sugar palm starch (TPS) was blended with poly(lactic acid) (PLA) to balance the individual polymer limitations and prioritize biodegradation feature. The results showed that incorporating SPCNC into TPS led to a significant reduction in water uptake of the blend in all mediums and a slight increase in soil degradation rate. However, PLA40TPS60 and PLA60TPS40 exhibited flammable properties.

Summary: This study investigated the influence of different processing input parameters on the heat-affected zone (HAZ) of SPF-UPE composites cut with a CO2 laser. Results showed that minimizing laser power and maximizing traverse speed and gas pressure gave the optimum HAZ response. Gas pressure had the most significant effect on the HAZ, with its contribution decreasing as material thickness increased, while the contribution of traverse speed increased with material thickness.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
