Summary: A novel flame retardant containing high amounts of P and N elements was designed and grafted onto cotton fabric via P-O-C covalent bonds, showing improved flame retardancy and durability. The treated cotton exhibited lower peak heat release rate, total heat release, and initial decomposition temperatures, as well as increased carbon residue during combustion, indicating the formation of an expanded char layer. Various spectroscopic techniques confirmed the flame retardant mechanism, and the mechanical properties of the treated cotton remained suitable for use after treatment.

Summary: In recent years, indoor fires caused by the flammable properties of cotton have become increasingly common, emphasizing the importance of flame-retardant cotton. Researchers have successfully developed a new flame retardant that forms stable chemical and coordination bonds on the surface of cotton fibers through a simple finishing process. This flame retardant exhibits excellent durable flame retardancy and does not significantly affect the physical properties of cotton fabric.

Summary: A novel flame retardant (POCODA) synthesized from POC and ODA was investigated for its effects on the thermal stability and combustion behavior of poly(L-lactic acid) (PLA) composites. The addition of POCODA/APP as a synergistic flame retardant showed improvements in the flame retardancy of PLA-based composites, with the optimal ratio achieving a V-0 rating. The proposed mechanism of flame retardance for the PLA/2%POCODA/10%APP composite was discussed based on SEM, TG-IR, and PY-GC/MS measurements.

Summary: A novel silicon, phosphorus and nitrogen synergistic flame retardant, EPSO-P, was synthesized and shown to improve the flame retardancy and thermal stability of cotton fabrics. The char residue of treated samples increased to 43% at 700 degrees C, while heat release rate and total heat release were significantly reduced after flame retardant treatment. EPSO-P was found to prevent the fabrics from burning in both gas phase and condensed phase, indicating it as a promising candidate for producing flame retardant cotton fabrics with favorable properties.

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.
