Summary: Antibiotic abuse has become a burden on patients and healthcare systems, leading to a need for non-antibiotic wound dressings. However, hydrogel wound dressings with good recoverability, toughness, and excellent antibacterial properties still face obstacles. In this study, a series of semi-interpenetrating network (semi-IPN) hydrogels were developed using quaternized chitosan (QCS) and polyacrylamide (PAM) through a one-pot method, which showed exceptional mechanical performance and remarkable antibacterial activity. The integration of quercetin (QT) further enhanced the antibacterial properties against S. aureus and E. coli. These high-elastic hydrogels have potential applications in wound dressing, tissue repair, chronic wound care, and other biomedical fields.

Summary: In this study, a special type of polymer matrix composite (PMC) used as a structural material in unmanned aerial vehicles (UAVs) was investigated. The microstructure showed a uniform distribution of E-glass fiber reinforcement in an epoxy matrix fabricated by the lay-up process. The study focused on adjusting the matrix by investigating the effect of a solvent, methyl hydroxide. The results indicated that the addition of methyl hydroxide improved the stability and mechanical properties of the resin. Furthermore, the addition of aluminum oxide as a secondary reinforcement increased the rigidity but decreased the tensile/flexural strength of the composite.

Summary: In this study, hydrophilic poly(lactic acid) (PLA)/poly(ethylene glycol)-poly(propyl glycol)-poly(ethylene glycol) (PEG-PPG-PEG) blended nanofiber membranes with various PEG-PPG-PEG concentrations were prepared using electrospinning. The properties and performance of the membranes were confirmed through various tests. The results showed that as the PEG-PPG-PEG content in the membranes increased, their hydrophilicity and fog collection ability also increased. These membranes can not only enhance the water harvesting capability of fog collectors, but also have potential applications in tissue engineering, drug delivery, scaffolds, and pharmaceuticals.
