Some studies have shown that the heavy metal emissions (HMEs) emitted from diesel engines can seriously threaten human health. HMEs are mainly related to the content of heavy metal ions in diesel fuel. Therefore, in order to reduce HMEs from diesel engines, a nano-fiber membrane filtration technology for diesel fuel was investigated.

- The research focused on the properties of polypropylene (PP) composites mixed with fly ash (FA) and waste stone powder (WSP) through injection molding, creating various formulations.
- All composites exhibited no surface cracks or fractures, confirming the reliability of the preparation method through thermogravimetric analysis.
- While tensile strength did not improve, the additions of FA and WSP significantly enhanced bending strength and notched impact energy by 14.58-22.22%, indicating potential uses in industries like artificial stone and flooring.
As an environmentally friendly water-soluble polymer, polyvinyl alcohol (PVA) has attracted extensive attention because of its non-toxic, degradable, low cost, and good biocompatibility. Electrospinning is a kind of nanotechnology, and the nanofiber membrane prepared by it has the advantages of large surface area-to-volume ratios, nano- to micron-sized fibers, etc. Herein, a simple and facile one-step green electrospinning method was developed to fabricate various environmentally friendly PVA nanofiber membranes.

- Volatile organic compounds (VOCs) contribute to air pollution and pose risks to human health and the environment, prompting the need for effective removal methods.
- The study developed polyurethane/rare earth (PU/RE) composite nanofibrous membranes through electrospinning to enhance VOC absorption capabilities.
- Analysis revealed that the PU/RE membranes with 50 wt. % rare earth nanoparticles achieved the highest absorption capacity—three times greater than pure PU—especially for VOCs like styrene, xylene, and toluene.
