Summary: Preparation of transparent flame retardant polymer composites is always a challenging task. In this study, a biodegradable carbon dioxide derived copolymer, polypropylene carbonate (PPC), was chosen for its importance in human environmental protection. By utilizing intermolecular hydrogen bonds, PPC composites were obtained by incorporating polylactic acid (PLA) and flame retardant guanidine phosphate (GP). The results showed that GP contributed to the composites with enhanced glass transition temperature (Tg) and flame-retardant properties, without sacrificing the intrinsic transparency of PPC. This study provides a facile approach to overcome the limitations of PPC for advanced applications.

Summary: In this study, a multifunctional PLA/TCP-Mg composite was fabricated by incorporating TCP microspheres and Mg particles into PLA matrix, aiming to enhance mechanical strength, accelerate pore generation, and improve biological and antibacterial performance. The compressive strength and stiffness of the composites were significantly enhanced, and as the Mg content increased, the elimination of reinforcers was faster, leading to accelerated pore generation and enhanced osseointegration. The PLA/TCP-1 Mg composite showed enhanced bioactivity with osteoblast cells and exhibited antibacterial properties.

Summary: Soil microorganisms play a crucial role in maintaining ecological balance, particularly through their involvement in nutrient cycles. Phosphate-solubilizing bacteria (PSB) are of particular importance in the rhizosphere and can be used as biofertilizers in agriculture. This study identified five species of PSB, including Pseudomonas fluorescens, P. putida, P. taiwanensis, Stenotrophomonas maltophilia, and Pantoea agglomerans, through genetic sequencing. The PSB isolates exhibited varying degrees of phosphate solubilization, with P. fluorescens showing the highest solubilization ability. Additionally, all five PSB species were capable of producing the growth-promoting hormone indole acetic acid (IAA), with P. fluorescens producing the highest quantity.

Summary: Biocomposites, with a focus on the use of polylactic acid (PLA) as the matrix material and cellulose fibers as the filler, have gained significant interest in recent years. The challenges posed by the hydrophilic nature of cellulose fibers in blending with hydrophobic polymers have been addressed in this study, along with the analysis of various shapes and forms of cellulose and mineral nanocomponents. The thermomechanical and physico-chemical properties of the resulting composites were examined, providing insights into the effects of shape and filling degree.

Summary: This study aims to fabricate a biodegradable polylactic acid (PLA) layer using the electrospinning process to replace the non-biodegradable polypropylene (PP) layer in 3-ply facemasks, making them more environmentally friendly. The results showed that the electrospinning method can produce PLA layers with similar thickness, narrow fiber diameter distribution, and slightly dense surface morphology compared to commercial facemasks. The synthesized PLA fiber layer exhibited significant improvements in tensile strength, Young's modulus, and elongation at break compared to the commercial samples. Additionally, the PLA samples showed significant degradation changes in seawater, river water, and soil environments, while only the soil environment exhibited significant weight changes after 45 days.
