Summary: This study investigated the effect of consuming a high-fat diet on internal exposure to glycidol. The findings showed that continuous consumption of lipid-rich foods reduces lipase activity, leading to decreased release of glycidol and reduced exposure. Therefore, monitoring lipase activity can provide a comprehensive assessment of the risk of glycidol ester exposure.

Summary: This study prepared a hemp fiber-reinforced composite from bio-based components, using hemp nanopaper and acrylated epoxidized soybean oil or acrylated rapeseed oil. The impregnation process was examined in detail, and it was found that rapeseed oil had excellent fiber surface wettability and a significant difference in viscosity compared to soybean oil. The rapeseed oil composite with 50% hemp loading achieved good mechanical properties and showed potential to replace epoxy/paper composite insulators.

Summary: Some Antarctic bryozoans can create calcitic bioconstructions that promote habitat complexity, but the processes leading to biomineral formation are largely unknown. This study investigated three Antarctic bryozoans, analyzing their morphological and skeletal features, as well as the organic matrix associated with the skeleton. The results showed variations in growth check lines, zooid length, and basal zooidal walls among the species. Preliminary characterizations of the organic matrix revealed the presence of proteins, polysaccharides, and chitin-related saccharides, providing valuable insights into biomineral formation in bryozoans.

Summary: Extracellular polymeric substances (EPSs) serve as an important carbon reservoir and promote carbonate precipitation in pelagic and benthic environments. This study explores the role of EPS produced by cyanobacteria during different growth phases in the formation of whitings. The production and characteristics of EPS were analyzed using various techniques, and in vitro precipitation experiments were conducted to evaluate the impact of EPS on carbonate mineral formation. The results suggest that EPS produced during the stationary phase plays a critical role in the formation of smaller carbonate minerals compared to EPS produced during the exponential phase.

Summary: Photopolymerization technology is limited in the fields of food packaging and biomedicine due to the high migration of small molecules from photoinitiators. In this study, a polymerizable 2-vinyl thioxanthone (ETX) was synthesized to improve the migration stability of photoinitiators. Macromolecular photoinitiators (PPI1, PPI2) were also prepared to further reduce migration. The results showed that the ETX/TEOA system had higher initiation performance and PPI2 displayed favorable initiation ability. Additionally, the migration of ETX, PPI1, and PPI2 in photocured film was significantly reduced. These low-migration photoinitiators have potential applications in the fields of food packaging and biological materials.

Summary: This study focuses on the development of high-performance, low-migration photoinitiators. A polymerizable photoinitiator (VBP) was synthesized by introducing an ethylene group into benzophenone, and three different molecular weight single-component photoinitiators (PVBN1-3) were synthesized based on VBP. The results show that these new photoinitiators have stronger absorption ability compared to benzophenone and significantly reduce the migration of initiators and co-initiators, addressing the safety concerns caused by migration.

Summary: This study investigates the effect of plasma treatment on carbon nanotubes (CNTs) and the structure/properties of polyimide (PI) nanocomposites with ultra-low content of CNTs. The results show that plasma treatment introduces isocyanate groups on the surface of CNTs and enhances the interfacial interaction between PI and treated CNTs. This leads to a significant improvement in the mechanical properties of the nanocomposites, with even a small addition of treated CNTs showing a substantial increase in Young's modulus, tensile strength and toughness.

Summary: The insertion of rigid aliphatic or aromatic building blocks in polymer structures is an effective way to synthesize high -Tg polymer materials. In this study, a series of isosorbide-2-aryl carboxylate-5-methacrylate monomers (ArIMAs) were synthesized by functionalizing isosorbide 5-methacrylate with various aromatic lignin-inspired esters. These monomers were polymerized to obtain high molecular-weight poly(aryl carboxylate isosorbide methacrylates) (PArIMAs). The resulting polymers showed high glass transition temperatures and thermal stability, making them suitable for use as high-performance plastics and coatings.
