Summary: In this study, reduced graphene oxide (rGO) nanosheets were spray-coated onto electrospun polyvinyl alcohol (PVA) nanofibers to fabricate a multilayer rGO/PVA film. The resulting flexible H-rGO/PVA-4 composite exhibited high thermal conductivity and was used as a thermal-interface material (TIM) for effective thermal management. Compared to a pure PVA film, the H-rGO/PVA-4 TIM facilitated lower surface temperatures for LED lamps. This study provides a universal approach for fabricating heat-dissipating composites of 2D materials and polymer films.

Summary: This study developed an active packaging material by encapsulating Zataria multiflora essential oil (ZMEO), a natural antimicrobial agent, into polyvinyl alcohol (PVA) fiber using electrospinning. ZMEO showed effective inhibitory effects on pathogenic bacteria, fungi, and yeasts. Scanning electron microscopy and Fourier-transform infrared spectroscopy confirmed the physical encapsulation of ZMEO into the PVA fiber. Strawberries treated with PVA/ZMEO exhibited better preservation of various quality attributes during cold storage. These findings demonstrate the effectiveness of electrospinning for encapsulating bioactive compounds and the potential of PVA/ZMEO for active packaging.

Summary: Graphene oxide nanosheets were used as a selective layer on a highly porous polyvinyl alcohol nanofiber support to synthesize composite nanofiltration membranes. By cross-linking the nanosheets and linking them onto the support surface using glutaraldehyde, stable membranes were produced with high solute rejection rates. This approach may offer a promising method for the fabrication of mechanically stable thin-film composite membranes effective in solute separation via nanofiltration.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
