Summary: The introduction of lignin helps reduce the cyclization degree and attenuate the exothermal rate of fibers, facilitating the stabilization process. The oxygen-containing groups in lignin act as free-radical scavenger and the carboxyl group accelerates the ionic cyclization of fibers. The oxygen structural unit of lignin is a promising candidate to enhance the stabilization behaviors of PAN-derived fibers.

Summary: The mechanical properties of carbon nanofiber mats are closely related to the fiber diameter. Smaller fiber diameters lead to larger cross-linking structures and higher graphitization degree. However, the tensile properties of the mats are not solely determined by fiber diameter but also by structural regularity and defects. The highest tensile strength of 125.2 MPa was achieved with a fiber diameter of around 500 nm.

Summary: Trimethylamine (TMA) is a malodorous substance that can cause odor nuisance to residents even at low concentrations. This study designed PAN/PANI fibers with abundant active sites by increasing the saturation difference between PAN and PANI in the precursor solution, resulting in a sensor with ultrahigh sensitivity and excellent repeatability to TMA. Scanning electron microscopy (SEM), Fourier transform infrared (FTIR), and Raman spectroscopy were used to analyze the effects of increasing PANI content on the fiber morphology and the proportion of PANI molecules on the fiber surface. The results showed that increasing saturation difference is an effective method for improving the sensing performance of electrospun conductive polymer fibers.

Summary: This research article introduces a novel composite material made of natural fiber and PAN fiber, aiming to address the issue of harmful materials in current composite materials. The study emphasizes the lack of research on PAN and natural fiber based hybrid composites. Therefore, Grewia optiva with good mechanical properties and PAN fiber with good tribological properties were used to develop the composites. The developed composites demonstrated promising physical, mechanical, and tribological properties.

Summary: This study investigates the effects of various additives on the stability of graphene nanoplatelet-based nanofluid phase change material for cold thermal energy storage. The results show that the nanofluid phase change material is stable with the appropriate surfactant, and it can significantly enhance thermal conductivity and viscosity. The type of surfactant also affects the phase change properties of the material. The integration of the nanofluid phase change material with a chiller can contribute to environmental pollution remediation.

Summary: The study found that PVDF fibers prepared under different conditions have similar crystallinity and melting point values, but analysis at the single fiber level showed a wide distribution of diameters and melting points. At the nanoscale, the melting point of nanofibers increases rapidly as the diameter decreases, with molecular orientation being the driving force behind the correlation between melting point and diameter of the nanofibers.
