AI Article Synopsis
- Two novel naphthalimide derivatives, SNI-Cz and SNI-DCz, were created and analyzed for their physical and chemical properties using techniques like NMR and HRMS.
- SNI-DCz demonstrated superior photoluminescence properties due to its unique D-π-A-π-D structure, showing weak fluorescence in pure DMF but a significant increase in fluorescence in a 40% water mixture, indicating a notable AIE effect.
- The analysis also revealed that SNI-DCz has good electron affinity and thermal stability, making it a promising candidate for applications in optoelectronics.
Article Abstract
Here, two novel naphthalimide derivatives SNI-Cz and SNI-DCz with AIE were designed and synthesized. The correctness of the two structures was characterized by NMR and HRMS. Their crystal structures, photophysical properties, electrochemical properties, thermal stabilities, fluorescence lifetime and yields have been characterized. Photoluminescence experiments revealed that SNI-DCz had superior properties due to the D-π-A-π-D structure and sliding away stacking of molecules. SNI-DCz exhibited weak fluorescence in pure DMF, with a significant AIE effect observed in the 40% water mixture and a sharp increase in fluorescence intensity was also observed. Cyclic voltammetry and thermogravimetric analysis indicated that SNI-DCz had good electron affinity and thermal stability. The excellent properties of SNI-DCz made it a promising emitter for optoelectronics.

The current unavailability of efficient myocardial repair therapies constitutes a significant bottleneck in the clinical management of myocardial infarction (MI). Ginsenoside Rb1 (GRb1) has emerged as a compound with potential benefits in safeguarding myocardial cells and facilitating the regeneration of myocardial tissue. However, its efficacy in treating MI-related ischemic conditions is hampered by its low bioavailability and inadequate angiogenic properties.

In anterior cruciate ligament (ACL) repair methods, the continuous enzymatic erosion of synovial fluid can impede healing and potentially lead to repair failure, as well as exacerbate articular cartilage wear, resulting in joint degeneration. Inspired by the blood clot during medial collateral ligament healing, we developed a composite scaffold comprising collagen (1 %, w/v) and polyvinyl alcohol (5 %, w/v) combined with platelet-rich plasma (PRP). The composite scaffold provides a protective barrier against synovial erosion for the ruptured ACL, while simultaneously facilitating tissue repair, thereby enhancing the efficacy of ACL repair techniques.

Abdominal hernia repair is a common surgical procedure, involving in most cases the use of textile meshes providing a mechanical barrier to consolidate the damaged surrounding tissues and prevent the resurgence of the hernia. However, in more than half cases postoperative complications such as adhesions and infections occur at the surface of the mesh, leading to chronic pain for the patient and requiring the removal of the implant. One of the most promising strategies to reduce the risk of postoperative adhesions and infections is to add a physical barrier between the mesh and the abdominal walls.

In this study, an alginate-chitosan (AL-CS) nanocomplex decorated with vitamin C coated iron oxide nanoparticles (FeO-vit C NPs) was investigated as a novel nanoiron fortification agent. The FeO-vit C NPs decorated on AL-CS nanocomplex underwent comprehensive characterization, including zeta potential, fourier transform infrared spectroscopy, X-ray diffraction, and UV-vis spectroscopy. The transmission electron microscopy (TEM) analysis confirmed the decoration of FeO-vit C NPs on AL-CS nanocomplex.

This study aimed to investigate the effects of freezing duration and matcha concentration on the rheological properties, moisture distribution, and multiscale structure of dough. The results indicated that both freezing and high concentrations of matcha (≥1 %) significantly reduced the stiffness of the dough matrix, restricted its ability to expand during fermentation, and disrupted the structure of gluten protein. Furthermore, freezing induced moisture redistribution within the dough.
