Summary: Flexible piezoelectric nanogenerators (PENGs) incorporating functionalized mono-/few-layered hexagonal boron nitride nanosheets (F-hBNNS) in a polyvinylidene fluoride (PVDF) matrix were fabricated for clean energy harvesting and powering low-power modules. The F-hBNNS showed enhanced piezoelectric properties compared to non-functionalized hBN, resulting in a 5.5 times increase in energy harvesting performance. The PENGs exhibited stable voltage output even after 1000 cycles of bending-unbending, making them compatible with wearable devices.

Summary: In this paper, electret treatment was used to enhance the electrostatic repulsion between the membrane and bovine serum albumin, resulting in improved anti-fouling ability and recycling rate of the membrane. The results showed that after the electret treatment, the surface potential of the membrane increased, the PVDF crystal type changed, and the crystallinity increased. Grafting N-vinylpyrrolidone onto MWCNTs reduced the contact angle of the composite film. The pure water flux, flux recovery rate, and rejection rate of the MWCNTs-g-PVP/PVDF composite membranes increased after the electret treatment, and the improved membrane performance was verified through circulation experiments.

Summary: With the increasing impact of antibiotics on the environment, membrane separation technology has been widely used to treat antibiotics in water environment. In this study, the surface of PVDF base film was modified by PEI to improve its performance. The results showed that the modified membrane had the best comprehensive performance when the molecular weight of PEI was 10,000 Da (P-10K). It could effectively remove antibiotics from both simulated water and actual river water, but it was also accompanied by a large degree of membrane fouling.

Summary: PVDF is rarely used as a substrate membrane for thin film composite polyamide nanofiltration membrane due to its hydrophobic surface pushing water away during interfacial polymerization. In this study, it was found that the pore size of the PVDF substrate greatly influences the morphologies and surface properties of the TFC PA NF membrane. The TFC membrane prepared with a PVDF substrate of 100 nm exhibited a 27.0 L m-2 h-1 bar-1 pure water permeance, and a 96.2% Na2SO4 rejection, demonstrating a facile and effective method for preparation of PVDF substrate supported PA NF membrane.

Summary: To mitigate membrane fouling and address the trade-off between permeability and selectivity, nanocellulose fine-tuned polyvinylidene fluoride (PVDF) porous membranes were fabricated. The incorporation of cellulose nanocrystals and oxidized cellulose nanofibers improved the surface charge, hydrophilicity, porosity, and tensile strength of the membranes. The NC-PVDF membranes exhibited enhanced flux, rejection, and fouling resistance, making them promising candidates for membrane separation.

Summary: In this study, the performance outputs of triboelectric nanogenerators (TENGs) were enhanced using polyvinylidene fluoride (PVDF)/fullerene (C-60) composite nanofibers (NFs). It was found that the incorporation of C-60 into the PVDF matrix improved the output power of the TENG devices, but an excessive amount of C-60 resulted in a decrease in power. The increase in C-60 content in the PVDF matrix enhanced the TENG performance by improving trap charge ability and electronegativity, and the output power was sufficient to operate a display device.

Summary: Limited understanding of stress response and tolerance to perfluorooctane sulfonate (PFOS) in plants exists at physiological, biochemical, and molecular levels. Lettuce exposed to PFOS showed accumulation of PFOS in leaves and roots, with different reactive oxygen species (ROS) production and defensive mechanisms observed between the two parts. Multiple defensive strategies in roots contribute to the high tolerance to PFOS.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
