Summary: In this study, the effect of chloride ion (Cl-) on the oxidation of 2,4-dinitrotoluene (DNT) by persulfate/Fe2+ was investigated. It was found that the presence of Cl- increased the content of hydroxyl radicals in the persulfate/Fe2+ system, leading to enhanced DNT removal. The transformation pathways of DNT were proposed, including hydroxylation/oxidation, elimination of the nitro group, and chlorination process. The toxicities of the intermediate products decreased during the oxidation process, but chlorinated by-products posed a higher toxicological risk.

Summary: The aim of this study is to investigate the p-toluene sulphonic acid (p-Ts.OH)-catalyzed reaction of racemic-azetidine-2,3-diones with enantiomerically pure cis and trans-4-hydroxy-L-proline in refluxing ethanol, resulting in the synthesis of substituted novel 3-(pyrrol-1-yl)-azetidin-2-ones at the C-3 position. An alternative synthetic route enabling the tandem transformation of proline to pyrrole, followed by intramolecular chirality transfer to the beta-lactams ring, was described. All four diastereomers of 3-(pyrrol-1-yl)-azetidin-2-ones could be achieved in good to excellent yield with high diastereoselectivity in a single-pot operation. This method can be applied to other activated carbonyl compounds, and functionalized pyrroles can be obtained through an expeditious process.

Summary: The synthesis and self-assembly of a silicon-containing liquid crystalline block copolymer (SiLCBCP) with high interaction parameter was reported, which contained thermally and photo-responsive azobenzene mesogens in the side chains. The phase transitions and orientation in the block copolymer were influenced by the molecular structural transitions of the azobenzene mesogens. A series of azobenzene-containing SiLCBCPs were synthesized through atom transfer radical polymerization, and the influence of the liquid-crystalline phase transition on the nanostructure of the block copolymers was described. Various nanostructures were obtained as the volume fraction of the PMAAzo block changed.

Summary: This investigation examines the relationship between the structure and properties of surface-grafted cellulose nanofiber (CNF)-based one-component composites. Key parameters, such as graft density, graft chain length, and interface structure, were systematically adjusted. Increasing the graft density and hydrophobic modification of the CNF surface improved thermal stability. Shorter graft chain length increased the T(g) of the graft chain while hydrophobic modification and longer graft chain length decreased stiffness. Decreasing graft density remarkably enhanced toughness and strength. The interfacial interaction between CNF and grafted polymer played a crucial role in determining the composites' properties, along with graft density.

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 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.
