Summary: In this study, temperature-, pH-, and electro-responsive materials were developed by loading poly(N-isopropylacrylamide-co-acrylic acid) (PNIPAm-co-AAc) microgels into polycaprolactone (PCL) nanofibers. The nanofibers exhibited thermo- and pH-responsive behavior within the range of 31-34 degrees C. Drug release kinetics could be enhanced by applying a pulsed voltage, and long-term temperature- and pH-responsive release was demonstrated. The nanofibers also showed switchable antibacterial activity and supported cell growth. Overall, these nanofibers have potential applications in wound healing.

Summary: In this study, electrospun poly((2-methylsulfinyl)ethyl acrylate-co-acrylic acid) (PMSEA-AA) nanofibers were synthesized as wound dressing materials for the first time. These nanofibers exhibited remarkable mechanical properties, hydrophilicity, cell viability, and antibacterial behaviors. Compared to pure acrylic acid (PAA) fibers, PMSEA-AA nanofibers showed higher tensile strength (9 MPa) and elongation at a break (30%), and achieved superior bacterial inhibition zones for Staphylococcus aureus and Escherichia coli.

Summary: This study develops a novel thermoplastic polyurethane/nanohydroxyapatite electrospun composite membrane-based piezoelectric nanogenerator (PENG) using polydimethylsiloxane as the substrate. The addition of nanohydroxyapatite and oxidized multiwalled carbon nanotube transforms the non-piezoelectric polyurethane into a piezoelectric composite material. Compared to pristine electrospun polyurethane, the composite samples show improved mechanical properties, thermal stability, dielectric properties, and piezoelectric characteristics. The optimized nanofibrous sample modified with the nHA/o-MWCNT hybrid filler exhibits exceptional dielectric properties and piezoelectric characteristics.

Summary: Tissue integration is a major challenge in tissue engineering and tissue scaffold development. This study explores the use of blend and composite materials to improve tissue integration. Poly(lactic acid) PLA and polysuccinimide (PSI) are used as the polymer components. The results show that the blend-electrospun meshes have a pronounced 3D structure and increased hydrophilicity. However, the blend meshes performed poorly in terms of degradation.

Summary: In this study, green reactive flame-retardant polyether polyols (GPP) were successfully synthesized by the ring-opening polymerization of environmentally friendly melamine resin (EFMR) with propylene oxide, and applied to prepare flame-retardant rigid polyurethane foams (RPUFs). The addition of GPP greatly improved the thermal stability and flame retardancy of the RPUFs, making them commercially viable. The GPP shows great potential for the development of specified flame-retardant PU materials.

Summary: Artificial protein cages, such as TRAP-cages, have potential applications in vaccines and drug delivery. TRAP-cages have the ability to control the disassembly conditions by modifying the interface between their building blocks. By using TRAP rings with different numbers of monomers, it is possible to predict the formation of other cages.
